On February 19, the Russian steelmaker Magnitogorsk Iron and Steel Works (MMK) announced the commissioning at the oxygen converter shop of its new secondary steel treatment complex, which is a part of its investment project for the creation of a complete cycle for plate production.
Accordingly, the commissioning of the new secondary steel treatment complex will allow MMK to cast crude steel at its continuous slab caster No. 6 at the rate of two million mt per year for the production of thick plates at its plate mill 5000. The purpose of the complex is to ensure that all steel acquires the characteristics needed to produce high quality pipe steel grades with strength characteristics of up to X120, and to broaden the mix of steel grades, especially as regards special steels.
Specifically, the secondary steel treatment complex will enable MMK to produce steel grades for high-quality pipes and automotive steel with carbon content up to 0.003 percent and sulphur content up to 0.001 percent. In addition, the modern dust and gas suppression system, integrated into the complex, will allow the company to decrease emissions at the oxygen converter shop.
MMK's secondary steel treatment complex was supplied by the German secondary metallurgical equipment producer SMS-Mevac GmbH.
