Metinvest Group’s Kametstal plant, which was built at the facilities of Dnipro Metallurgical Plant (DMK, Kamianske, Dnipro region), is expanding the range of steel that can be smelted using economical technology with preheating of scrap metal.
According to the company, the peculiarity of the efficient preheated smelting technology is that immediately after scrap metal is fed into the converter, before liquid iron is poured, the scrap is heated with oxygen and using gas coal. This makes it possible to increase the use of scrap metal, which reduces the consumption of liquid iron in steel production and thus its cost.
It is noted that to develop and implement this technology in Kametstal’s BOF Shop, the smelting parameters were carefully selected, the amount of oxygen and gas coal for heating was determined, as well as the optimal scrap heating modes to prevent the formation of a liquid phase during pig iron pouring and the modes of smelting blowdown.
“The proven technology has already proved its economic efficiency in compliance with the parameters and requirements for the quality of steel produced in the converter. Therefore, steelmakers continue to develop and improve their achievement, systematically increasing the share of melts with scrap preheating and reducing the consumption of liquid iron during steelmaking,” the information summarizes.
“Kametstal was established on the basis of Dnipro Coke and Chemical Plant (DKKhZ) and Central Steel Works (DMK).
According to the 2020 report of Metinvest Group’s parent company, Metinvest B.V. (Netherlands) owned 100% of the shares in DCCP.
