Quality assurance

The products described in this brochurerepresent the latest stage in the developmentof non-oriented fully processed electrical steels.They are subjected to rigorous quality controlprocedures throughout the processing routes.The quality management systems of OrbElectrical Steels Ltd and SurahammarsBruks AB are approved by Lloyd’s RegisterQuality Assurance Limited to the QualityManagement System StandardsEN ISO 9001/9002 (respectively) applicableto the manufacture of electrical steels.

Quality logging system

Cogent Power Ltd is continuously developingprocessing systems to provide customers withproducts of enhanced quality. A part of thisdevelopment is the unique, computerized,quality logging system at SurahammarsBruks AB, based on continuous monitoring ofthe processing variables. Large quantities ofmeasured data for each coil are stored in adatabase and are available on demand ingraphical or numerical form.

A computer on each production line collectsand displays process information to the lineoperators. Parameters such as line speed,furnace temperatures and continuous stripthickness are continuously logged. Included inthe system is a continuous measurement ofloss along the length of the annealed strip.Although this is not an absolute andstandardised method, it provides valuableinformation on the quality of the material.

The logged data is instantly available for usersin, for example, Production, Maintenance,Quality and TR&D departments so that lineperformance and product quality can beanalysed in order to improve the processesand products. The general structure of thesystem also makes it possible to collate datasuch as hot rolling parameters from feedstocksuppliers. The flexibility of the system enablesthe user to perform anything from an instantcheck on the quality of a particular coil to adetailed analysis over a large number of coilsand their processing parameters.

Cogent non-oriented fully processed electricalsteels are free from magnetic ageing.

Ageing, or the increase of power loss withtime, is caused by an excessive carbon contentin the steel. The carbon content is continuouslymonitored by state-of-the-art analyticalequipment to ensure freedom from ageing.

3) Tolerances according to European Standard, which also fulfils requirementsaccording to ASTM A677 (except for cut lengths between 25.2 inch and30.0 inch as can be seen from the table).

4) The European nominal thicknesses are conversions from metric: 0.0138 inch = 0.35 mm, 0.0197 inch = 0.50 mm, 0.0256 inch = 0.65 mm

where the strip is rolled to European standards. Sura’s control of thicknesstolerances is more stringent than ASTM A677 resulting in final products forthicknesses 0.0140 inch and 0.0250 inch remaining within specification. Thenominal metric version of the 0.0185 inch thickness however, can be at aminimal variance. Sura's control of this variance gives a likelihood of less than5% in terms of number of coils outside the ASTM + tolerance and no coilsoutside +0.0020 inch of the ASTM nominal thickness.

Coatings

The surface of Cogent non-oriented fullyprocessed electrical steel is clean, smooth and hasa very thin layer of oxide. To improve surfaceinsulation resistance, grades are normally suppliedwith insulating coatings. Coatings have differingproperties and the thickness can be varied,normally ranging from 40 to 120 µinch.

All coatings have excellent adherence and

will withstand normal punching operations.Cogent coatings provide some corrosionresistance and have only a marginal effect onstacking factor.

The schematic diagrams below provide anindication of how coating properties are relatedand how they depend upon thickness and typeof coating.

National and international standards

ASTM American Society for Testing and MaterialsAISI American Iron and Steel InstituteEN European StandardIEC International Electrotechnical CommissionJIS Japanese Industrial StandardGOST National Standard of the USSR

Electrical steels are designated according tothe guaranteed maximum core loss at a peakmagnetization of 1.5 T and 60 Hz.

In the table on page 13, Cogents’ presentgrades are compared with previousdesignations and International standards.

Standards usually include other magneticrequirements (eg for minimum magneticpolarization). Such requirements are excludedin this comparison.

AISI standards for electrical steels expiredmany years ago, but the designations of theold AISI standard are still frequently used andtherefore included in the comparison onpage 13.

The European standard EN 10106 hasbeen implemented as National Standard in allcountries of the European Union, as well as inIceland, Norway and Switzerland.

Many national and international standardsare based on metric units and a test frequencyof 50 Hz. There is no exact conversion of lossdata from 60 Hz to 50 Hz, but the followingapproximate relationships may be used forlosses at 1.5 T:

Comparison of grades and standards

* These grades do not appear in the standard ASTM A677.Note: A designation within brackets, eg (M19) indicates approximate equivalence.

Conversion factors1 Tesla (T) = 1 Weber/m2 (Wb/m2) = 10000 Gauss = 64.5 kilolines/sq.in.

1 A/m = 0.01 A/cm = 0.0254 A/in = 0.01257 Oersted

1 W/lb = 2.205 W/kg (at the same frequency)

1 VA/lb = 2.205 VA/kg (at the same frequency)

1 N/mm2 (MPa) = 145.0 psi (lbs/sq.in.)

1 inch = 25.4 mm

1 kg = 2.20 lbs

Stress relief annealing

Cogent non-oriented fully processed electricalsteels are supplied finally annealed with fullydeveloped magnetic properties and arenormally used without stress relief annealing.

Applications

Cogent grades cover a wide range ofproperties. Since the materials are fullyprocessed the properties are fully developedin the ‘as supplied’ condition. From themagnetic viewpoint, different grades arecharacterised, primarily, by values of powerloss and permeability. An increasing alloycontent (mainly silicon and aluminium)increases electrical resistivity of the steel andthus reduces power loss. On the other hand,an increased alloy content results in reducedmagnetic saturation and reduced permeabilityat medium and high field strengths(H >1000 A/m).

Generally, higher permeability is moreimportant for smaller machines whereaspower losses are of greater importance forlarge machines. Grades of lower alloy contentwith higher losses, higher permeability andlower cost, are therefore mainly used for smallmachines. Grades of high alloy content withlow losses, lower permeability and higher costare used for large machines. There are,however, many exceptions to this.

The table lists examples of suitable Cogent grades for various applications.

To make best use of low core loss of thesteel, edge deformation zones and burrsshould be minimised during the laminatingprocess by using sharp tools, preferably thosewhich are highly wear-resistant such astungsten carbide. The additional cost ofannealing for improvement of magneticproperties can normally only be justified forvery narrow laminations.

Some aspects of stress relief annealingprocedures are given in the Cogent GrainOriented electrical steels brochure. For stressrelief annealing, uncoated or SURALAC 7000coated steel should be used. 36F135 –

Thin non-oriented electrical steels for medium to high frequencies

For applications at frequencies higher thanthat of the normal power frequency(50 or 60 Hz), it may be necessary to select athinner steel to maintain low losses. A rangeof thin non-oriented fully processed electricalsteels for application at medium to highfrequencies (200 -3000 Hz) has beendeveloped.

Thin gauge grades are available with aninsulating coating, SURALAC 7000 (see page11), or as uncoated strip. For more detaileddescriptions, please refer to separate Cogentbrochures.
