Severstal, one of the world's leading vertically-integrated steel and mining companies, has patented the technology for the production of an innovative carbon-containing product (IPUS). It is used as a fuel for blast furnaces at the site of the Cherepovets Metallurgical Plant (CherMK, part of the Severstal Russian Steel division).
The product was developed and implemented by specialists from the Center for Technological Development of Coke and Blast Furnace Production of CherMK in cooperation with Coke Shop No. 1. The technology allows the use of low-value coal grades from Vorkuta deposits, which were previously considered only conditionally suitable for coking.
“One of the steps in reducing the cost of liquid steel production and ensuring the company's raw material security is the maximum use of the products of our resource assets at CherMK. The basis for this is provided by experiments with coal and iron ore raw materials. The introduction of innovations in the first stage of the technological chain allows Severstal to feel more confidently at the forefront of the new and increasingly serious challenges that the volatile market presents to us, ”commented Evgeny Vinogradov, CEO of Severstal Russianstal Division and resource assets.
The product is used at the CherMK site since December 2018. Today, slave furnaces are almost completely transferred to the use of solid substitute for coke. The end-to-end economic effect of using the IPUS (from December 2018 to the present) amounted to $ 29 million.
