Melt Yard and Deck Basics (Training Moments)
Larry Helm
Seneca Foundry We Bring Iron to Life
ABSTRACT This article is a written version of a presentation made at the Ductile Iron Society Meeting held in Peoria, IL on October 24-26, 2012. It contains basically three components: 1st a little about who is Seneca Foundry, 2nd some information about melting and alloying practices employed at Seneca; and 3rd some general observations gathered over the years on melting, alloying, and general foundry topics. WHO IS SENECA FOUNDRY We are a family owned foundry located in North Central Iowa; that can trace our heritage as a company back over 100 years. Metals poured include: Gray Iron grades G30, G35, and G40; Ductile Iron grades D60, D65, D80, D100, and D120; along with Austempered and High Silicon-Moly Ductile Irons. Molding entails: Green Sand a Hunter 10 to a turntable and a Hunter20 to pallet lines, weights 1-90#; No-Bake weights up to 250#; and Lost Foam weights up to 100#. Core making consists of Shell, Cold Box, and No-Bake. Heat treating in house is annealing and stress relieve, other is performed by outside sources. Melting is by 2-2 ton medium frequency furnaces. Also included is Top Notch Tooling, a full service pattern shop; and Gold Chip Machining, a casting machine shop.
IRON YARD Our iron yard is very simple, one grade of steel, from one source (a back-up source is available).Manganese content is a compromise for use in both Gray and Ductile iron. Many foundries are not able to accomplish this and as a result will have piles of several grades in their yards. For us it works well, and allows us to minimize our need for inventories and storage area. In pig iron again only one grade is used (also from only one supplier), and is used only in Ductile Iron to control Mn and other elements levels in our base iron. Our returns are stored in meal tubs by iron type. Each gating system and riser is marked with the corresponding iron grade ex: G30, D80, etc. and after blasting is placed into the metal tubs. Unlike in cupola melting returns segregation for S control is very important in electric melting, so we work hard in keeping materials properly separated. Which brings us to our first Universal Law.
MURPHYS LAW OF IRON YARDS
Beware, keep everything well marked and separated on the yard;
especially all grades of returns!
Nothing is worse than going looking for that special material that was put out onto the yard the other day, and finding it gone; mixed into who knows whatever pile or charges. As mentioned before all of our returns are blasted and then handled in tubs in the yard. We work to keep sand, dirt, trash, non-ferrous material, and junk out of the iron yard. This leads to our next law.
THE 1st LAW of ELECTRIC FURNACES
Metal is easier to melt than Slag.
Studies have been done showing that is takes several times the number of kilowatts of power to melt 100# of slag as 100# of metal, thus anything that can be done to minimize non-metallics in our melt yards, and thus our charges; improves the efficiency and cost effectiveness of our electric melting operations. Cupolas are a different animal; there more dirt/sand can be tolerated due to the slagging practice that is established in order to flux the surface of the pieces of coke for maximum carbon and heat transfer. But even in cupolas if too much in the way of this dirt and sand is added (especially going into mud in inclement weather) you can pay a real penalty in chemistry and temperature control, along with excess flux and coke usage. Bottom line, a cleaner charge is a better charge. MELTING OPERATION Our furnace linings are Silica with 1.0% Boron Oxide, thus on sintering in a lining with Ductile Iron we will experience the B ferritizing effect on pearlitic grades. We try as much as possible to sinter in on Gray Iron. As a bonus the higher Si content in the sinter also seems to start the lining out better, with less overall wear and patching over its life. We will take a lining out after 35 to 45 heats, we tend to be conservative on this, but we also have outstanding coil life. If we must sinter in on Ductile Iron, we definitely stay away from pouring D100 right after the sinter; and even D80 if possible. If we have to go D80 we will over alloy with Mn for a period of time (typically for 2 hours), to counteract the B effect. In our charge make-up all materials are weighed against a designated recipe, and are dried out (not preheated) before charging. The importance of precise material weights cannot be overstated. This gives us another law.
THE 2nd LAW of ELECTRIC FURNACES
What you put in, is what you get out!
Again cupolas are different. There in charge make-up you are looking at losses in certain elements, such as Mn, Si, etc. This effect, along with the fact that various materials melt at different levels in the stack, gives you a sine wave of chemistries. With a cupola you are always looking at the center of the sine wave as your desired chemistry. But in electric melting these losses dont occur. What you see is what you get. To me making charge make-up that much more important in electric melting. We use a heel melting practice, thus the drying of the charges mentioned earlier. Dont want wet metallics being submerged in the bath. Molten iron and water dont mix well. Our initial charge into the furnace is 3800# and we normally tap out 550# ladles. Thus we are only changing 1/7 of the furnace on each tap/charge. This allows us pretty consistent chemistry control. We will pour multiple metal grades in a day, utilizing change-over charges (one per furnace) to go from Ductile to Gray, or from Hi-Sil-Moly to Gray. This brings up the cast iron version of pour acid into water.
CAST IRON LAW of MIXING Ductile can go into Gray, but not the reverse!
Ductile returns can mix into Gray iron allowing for extra alloys to be used. The reverse raises the S content in the Ductile, undesirable. Ductile carbon raisers again OK, you will have to add some S. The reverse is a disaster, just ask someone who did it! Even in ferrosilicons it is true. What would happen if a Ti ferrosilicon, good in Gray Iron for certain conditions; got accidently added to some Ductile? As a result we always refer to the Law of Mixing. ALLOYING For furnace alloys we use two carbon raisers, one for Ductile and one for Gray; S content obviously being the difference. One common SiC, iron pyrite to flavor the Gray Iron, a low alloy 75% FeSi for silicon units as needed, Ferro Mn and Cu and Ferro Moly for trimming. Our Ductile is produced using a tundish treatment ladle, our own design; using a Balanced (1%) RE, 5% MgFeSi. The final inoculant for both metals is a Ca Bearing 75% FeSi. Ferro Mn, Cu, and Ferro Moly are used for ladle additions for various iron grades. Some Ti Bearing 50% FeSi is used for some special Gray Iron jobs. It is kept basically under lock and key. Which brings up the:
LAW of FERROSILICONS
All Ferrosilicons are not created equal!
How often have we heard in our shops But they looked the Same! In my career ferrosilicons have caused more probably issues than any other alloys, other than maybe Sn; or possibly FeCr in Ductile Iron. Our Ferrosilicons contain various levels of combinations of Al, Ca, Sr, Z, Ba, Ti, and who knows what else! Trying to explain to someone on the floor why some are meant to work better than others for certain applications, has always been a challenge. While talking about ferrosilicons two other items come to mind. Overall in our industry we have tended to use inoculants of too large of a size for a given application. For instance the sizing which would be good for a 5000# transfer ladle; is not what you would want to use in a 500# pour off ladle. Studies have shown that the smaller the amount of iron, the smaller the sizing should be on the inoculant. Also the uniformity of sizing, controlling a consistent % of fines is important. Our final inoculation is done upon the transfer of iron from the transfer/treatment ladle into the pour off ladle. On some certain jobs we add an additional inoculant into the mold. You can add an inoculant in the transfer ladle, in the pour off ladle, into the iron stream, into the mold; or into multiple locations. Any of which can be effective processes. CHEMISTRIES You will naturally end up choosing C and Si ranges that suit the type of castings which you pour. At the same time you will control residual element levels, and levels of Pearlite formers and stabilizers for the grades of metal which you pour. But eventually you will bump into:
HELMS LAW of CHEMISTRIES
There will always be one (or more) jobs that will not run in your established ranges. Accept it, and adjust as needed.
Or, get rid of the job(s)!
Over the years I have been able to keep many gating/rigging people very busy in trying to solve scrap issues that we eventually only solved by adjusting the chemistries, typically C and Si. If you cannot easily do these necessary adjustments on an individual job basis, then help out your head and tell sales to remove the brick wall. At Seneca we re-gated one Gray Iron job multiple times in order to prove what Taguchi experiments had showed; that only a higher carbon would solve the issue. Result back to the original gating, and scheduling of pour off to allow the higher carbons. This can also happen with certain parts in especially heavier (or thinner) section sizes, where sometimes creative alloying is required.
TESTING/SAMPLING We test the base iron always before starting to pour from a furnace, both thermal analysis and spectrometer samples. Any adjustments are made before starting of pouring. After we start pouring additional base furnace samples are poured every 4 ladles/charges. Final chemistries are poured with any test bars, with additional finals throughout the day on Gray Iron; and a final on every ladle of Ductile. We wont burn all of them, but we pour them to have available in case we see any possible issues. We use chills sometimes on Gray Iron when looking for data, and pour micros on all ladles of Ductile. We always burn all specto samples 3 times. Good testing is important to keep from falling into:
MURPHYS LAW of CHANGES
Never make a major process change on data from only one test!
Ever have someone make an alloy % change to the MgFeSi after making only one burn on a sample, only to find that the single burn was on a slag stringer? Or make big C and/or Si addition changes on what turned out to be a faulty T/A cup reading? Enough said. Refer to the above law when preparing to make changes to the operation. Besides routine testing; look at testing the metal under any/all conditions. This would include for instance out of a furnace that has sat for a while, at start-up, the first ladle of the day; and at pour-off, the last ladle. It may tell you some interesting information about the metal going into your castings. You may find yourself at the:
3rd LAW OF ELECTRIC FURNACES
Unlike professional wrestling, Monday Morning Iron is Real!
It can, and will exist, in any style of electric furnace: coreless melters, channel holders, or pressure pour units. Monday Morning Iron is basically metal which has suffered a loss (or destruction) of nucleation. It can happen faster than you think, especially in medium frequency melters. We can see it happening especially on holding the furnaces overnight; and on furnace pour-off on Gray Iron. We have worked on the issue by adjusting charge materials/alloys to increase nucleation, and by paying closer attention to furnace metal temperatures. Now the:
4th LAW of ELECTRIC FURNACES
DO NOT superheat the metal any more than necessary!
Increased and/or unnecessary superheating will only harm the metal, nothing good comes from it. It can contribute to more slag formation, it causes destruction of nucleation, it can cause carbon boil; it is bad for the furnace linings. And at the same time it raises your costs for the additional electricity. Just dont put any more power into the metal than you need for good operations and the types of castings you are pouring. OTHER FOUNDRY GOOD PRACTICES This discussion on metal superheating is a great lead-in to a good rule of thumb adhered to by my old foundry professor.
METAL CHARACTERISTICS
Pour any given part: As cold as you can. As fast as you can;
And, as quietly as you can! Dr. D.C. Williams, OSU
This statement doesnt mean to pour all iron at a temperature that is barely liquid. It means simply dont pour any hotter than is necessary for that given part. It doesnt mean to fill the mold so fast that it blows out at the parting line. It does mean not to dribble the iron in so slowly that bad things start to happen to the mold and the metal. And it does mean to try to design the gating to minimize iron velocity and turbulence during filing. All of these characteristics will help in producing good castings. For more on pouting times refer to this old rule of thumb for horizontally parted molds.
POURING TIMES
A reasonable aim point in seconds; is the Square Root of the Pour Weight of the Mold.
As an example this would mean a 10# mold in about 3 seconds, a 100# mold in 10 seconds, a 1000# mold in 31 seconds, and a 100,000# mold in about 5 minutes. Is this a hard and fast rule, no it is an approximation. Some people would say we cant pour that fast; others would say we would never pour that slow. But I would bet that if you go out and time a number of jobs you will be slower than these numbers/times. Again the point here is the same as Dr. Williams. The faster you can fill an individual part, the better off you will be. As examples obviously vertical machines are much faster than these times, with only say 5-6 seconds of time to fill a mold. And in Lost Foam you can see downsprues with designed fill rates as high as 30-50# per second. TRAINING MOMENTS At the beginning of this article under the title, I had in parenthesis the term Training Moments. At Seneca each morning the Plant Manger has a meeting where we review production results against plan, scrap rates, safety subjects, and also a segment we call Training Moments. In just a few minutes we will go over topics such as the ones in this article on melting. And others such as sand, molding, cores, heat treat, clays, etc, basically just about any topic concerning foundry operations. The idea is to present in bite sized chunks, little bits of knowledge/wisdom concerning foundries. We have been doing this for over a year and have had good feedback from employees as they better learn how and what they do affects the castings they are producing. To finish I will leave one more nugget of wisdom from a supervisor I once worked with who was tired of dealing with runouts on a particular part number. He stated:
PLOGS LAW
You generally get a much better looking casting if you keep all of the metal in the mold!
Thank you.

IntroductionIntroduction Optimizing Magnesium Recovery.
There are several ways to treat ductile iron and the scope of this presentation will focus on MgFeSi alloys.MgFeSi alloys.
The converter process and cored wire process are beyond the scope of this presentation.
MgFeSi alloys have low vapor pressures which makes the addition of these alloys challenging.y g g
They react violently which makes recovery of the Magnesium difficult.
Introduction Due to the low vapor pressure there is one
over riding theme in increasing Magnesium Recovery. Delay the reaction as long as possible to
maximize the amount of magnesium capturedmaximize the amount of magnesium captured by the iron.
Cover Materials Purpose is to delay the MgFeSi reaction as
long as possible allowing for more iron capture of magnesium.

Allowing for as much iron and slag to naturally fall out of ladle as possible makes operators job easier and helpsladle as possible makes operators job easier and helps to extend the life of the pocket.
Timing and Iron Controlg Add alloy just before tapping iron.
The heat in the ladle can initiate ignition ofThe heat in the ladle can initiate ignition of MgFeSi alloy.
Tap temperature will directly impact the t f M F Si d damount of MgFeSi needed.
Increasing the speed of tapping or improving the insulation on ladle will allow for lowering tap g ptemperature which directly reduces the amount of alloy needed.
Consistent Base Sulfur control is also Consistent Base Sulfur control is also necessary for consistent recovery. Operators tend to error on the safe side, so it is
always easier to increase Mg than to decrease Mg.
Timing and Iron Control g Avoid torching as long as possible.
The torching causes a sulfur reversion which will require additional MgFeSi upon start uprequire additional MgFeSi upon start-up.
Torch heat is only surface heat and does not penetrate the lining, try only using for known extended down times.
Ladle washing with iron is much more effective for heating g gup a ladle but is often not feasible in many operations.
Be aware of where chemistry results are coming from.g Some foundries are testing chemistry after treatment.

Alloy Design Discussion The Magnesium Reaction.
Mg + O = MgO Mg + O = MgO Mg + S = MgS
Magnesium will deoxidize and desulfurize and this action contributes to the Magnesium Requirement.
Mg Recovery = .76 (Sbase Sfinal) + Mgresidual x 100 Mginitial [1]

oxygen and sulfur would allow foroxygen and sulfur would allow for better utilization of the Magnesium.With thi i f ti l k t With this information we can look to the Ellingham Diagram for ideas to

Alloy Design Discussion Aluminum.
From the Ellingham diagram we see Al will react more dil ith O th M t l t d t treadily with O than Mg at elevated temperatures.
Aluminum is recognized for contributing to pinhole formation in iron castings..Aluminum will also add to the slag formation resulting in poor furnaceto the slag formation, resulting in poor furnace performance, more ladle and holder maintenance and increased risk for slag inclusions in castings At higher aluminum levels, FeSi-based alloys will tend to i l bilit b t th i d l f tiimprove solubility, but the increased slag formation and tendency for pinholes should call for caution. [4]
The greatest benefits were achieved when Al was introduced in to the iron via the inoculant late in theintroduced in to the iron via the inoculant late in the process or as a pre-conditioner of the base iron early in the process. Al added via the MgFeSi provided the minimum benefit. [4]
Alloy Design Discussion Barium.
One of the objectives of a O e o t e object es o apreconditioning treatment with high level of barium containing ferrosilicon is to manage or control the oxygen and sulfur activity, promoting the formation of oxysulfphides of barium (BaO andof oxysulfphides of barium (BaO and BaS).
