Capacity: 2.5 Mio t/year HDRI/CDRI
Furnace Type: Midrex Megamod® 7.65 m dia.
Reformer: 8 Rows x 18 Bays
Project description
In May 2015, the Turkish Steel producer
Tosyali Holding awarded Midrex Technologies,
Inc. and its partner Paul Wurth S.A. the
project to build the world’s largest multiple
product direct reduced iron plant for the
new steelworks of Tosyali Algeria located in
Bethioua (Oran), Algeria.
The new MIDREX NG™ Combo Direct Reduc-
tion Plant was designed to produce 2.5 million
tonnes of direct reduced iron per year and
has the capability to vary its production to
produce hot direct reduced iron (HDRI) and/or
cold direct reduced iron (CDRI) simultaneously
without any stoppage of production. This new
DRI plant is the largest single DRI facility to
produce multiple DRI products in combina-
tion ever built. HDRI is fed via a hot transport
conveyor to a new electric arc furnace (EAF)
located adjacent to the MIDREX® DRI plant
allowing for greater EAF productivity and
energy savings. CDRI can also be produced for
additional on-site use.
This new MIDREX® DRI Combo Plant provides
the Tosyali Algeria steelmaking facility with
greater production flexibility to produce high
quality, low impurity steels as well as to de-
crease their demand for imported scrap.

Main project data
Order received: May 2015
Start of commissioning: June 2018
First production of cold DRI (CDRI): November 2018
Hot DRI (HDRI) production and
official plant start-up:
February 2019
Benefits of Hot Direct Reduced Iron
There are two main benefits of charging
hot DRI (HDRI) to the EAF: lower specific
electricity consumption and increased pro-
ductivity. Energy savings occur because less
energy is required in the EAF to heat the
DRI to melting temperature, resulting in
reduced electricity consumption of about 20
kWh/t liquid steel for each 100° C increase in
DRI charging temperature. The productivity
increase is related to the reduced tap-to-tap
time (up to 20%) compared to charging CDRI.
Additional benefits of charging hot DRI (HDRI)
to the EAF are:
yy Reduced electrode consumption
yy Lower overall emissions due to lower
electricity demand and reduced need for
charge carbon
