OEMK. In 2018, OEMK saw the opening of a scientific and technical steel smelting laboratory in which Metalloinvest and NUST MISiS invested over RUB 60 m (about USD 1 mn). The laboratory’s vacuum-induction furnace with a maximum load of just 60 Kg provides for rapid experimental smelting of small volumes, which is impossible using OEMK’s 150-tonne industrial furnaces. This allows the specialists at OEMK to conduct more experiments and substantially reduces research costs. Recently, metalworkers at the scientific and technical steel smelting laboratory at the A.A. Ugarov Stary Oskol Technical Institute, which is located on the grounds of OEMK, conducted a series of projects jointly with scientists from the higher education institution to develop a new steel grade: sparingly alloyed chrome-manganese steel.
According to Ivan Malikov, Head of the Department of New Products at OEMK, the new grade was developed especially for the Slovakian company HKS, a leading manufacturer of forgings and stamping products in Europe, which are used in the automotive and mechanical engineering industries. The collaboration with the institute allowed us to satisfy the full range of technical requirements put forward by HKS.
As explained by laboratory leader Alexei Kozhukhov, Head of the Department of Metallurgy and Steelmaking at the A.A. Ugarov Stary Oskol Technological Institute of NUST MISiS, 37 smeltings were carried out for the selection of chemical components of steel, which enabled the formation of mechanical, hardening and exploitational characteristics of the end product according to customer demands.
As part of the programme for improving the quality of SBQ, by 2020 Metalloinvest will build in the OEMK Finishing Shop a facility with a capacity of 70,000 tonnes of SBQ bars (the project is costing approximately RUB 3 bn (in the region of USD 47 m)). It will permit various types of heat treatment to be undertaken (in a broad temperature range of 400-980 °C) required for producing steel for springs, ball and roller bearings and construction, as well as for high-strength metal.
Fabrizio Pere, CEO at equipment supply company Danieli Centro Combustion: “We are proud to be Metalloinvest’s partner for the heat treatment expansion project of the high-quality SBQ bars at OEMK. The furnaces, which process bars ranging from 19 to 90 mm in diameter, will perform five different heat treatments: isothermal annealing (standard and pendular), spheroidizing annealing, high-temperature tempering, and under annealing. Our partnership combines our furnace manufacturing capability together with know-how in the metals and mining industry.
