OREANDA-NEWS. February 11, 2009. Yenakiyevo Steel Plant (YeMZ), which belongs to Metinvest Group, is trying to master production of five new steel grades using innovative technology. YeMZ developed a comprehensive steelmaking and deoxidation program that makes it possible to increase the range of finished products for construction such as reinforcing and round steel bars with diameter of 5,5-12mm, reported the press-centre of Yenakiyevo Steel Plant.

The innovations are introduced within the comprehensive development program of Metinvest Group enterprises.

Technologies are implemented according to the pattern "converter - ladle furnace - continuous casting machine" and are used to cast billets on continuous casting machine-1.

Within the chain "converter - ladle furnace" YeMZ has developed a new technological process for low-carbon steel grades SAE 1006-1010. It replaces traditionally used aluminium with ferro-calcium to deoxidize low-silicon steel (rimming steel).  In addition, YeMZ specialists managed to receive the best manganese-silicon ratio in the chemical composition of steel to be used for low-alloy 25G2С и 35GС steel grades. Ground-breaking solutions make it possible to cast billets with an open jet; as the result the plant has reduced production costs without damaging the quality of the output.

"National and international mining and metals companies do not practise casting of rimming low-carbon steel grades on continuous casting machines with an open jet as it is quite a complicated process", said Aleksandr Podkorytov, CEO of YeMZ. “To master new technologies our steelmakers developed optimal alternatives of billet casting. Continuous casting machines are equipped with modern systems allowing to quickly change metering nozzles, that's why we can now regulate the casting speed".  

At the moment Yenakiyevo Steel Plant makes 25 steel grades.

Profile:
Steel grades:
25G2С is constructional low-alloy steel for welded steel structures. It is used to make steel reinforcement bars.

35GС is carbon low-alloy steel. Building bars are used for reinforcement of concrete-steel constructions. 

SAE 1006, 1008, 1010 is constructional low-carbon low-silicon steel. It is used as wire to produce grids.

Ladle furnace - CC machine is a continuous casting machine.
YeMZ Group is one of global leaders in marketable billets production. The Group includes OAO Yenakiyevo Metal Plant and Ukraine-Switzerland Joint Venture Metalen, LLC both operating at the same industrial site and having a common production cycle. The company produces rolled and cast billets, wire rods, and different section bars (beams, channels, angles, etc.). YeMZ is a part of Steel and Rolled Products Division of MetinvestGroup.
