Russia: Eurocement has signed a contract with Russia’s fourth largest steel company, Novolipetsk Steel (NLMK), for the supply of an estimated 25,000t of cement over the three months to 31 December 2019. Metal Daily News has reported that the cement will be used in conjunction with NLMK’s blast furnace slag to produce briquettes at a rate of 0.7Mt/yr.

Russia: NLMK Group has signed a five-year contract for the supply of raw materials, including granulated slag, to Eurocement group. The contract, which runs until the end of 2022, covers an annual supply of up to 5Mt of raw materials for use as primary feedstock and additives for cement production at seven Eurocement plants. The raw materials to be supplied also include iron-containing additives, chalk, clay and limestone screenings.

“NLMK Group has been working with Eurocement for several years, on short-term contracts. This new long-term agreement has taken our partnership to a new level. It will make our relationship more open and structured, simplify clearing and settlement and reduce the risk of changes in the market impacting the supply of materials,” said Ilya Guschin, NLMK Group’s Vice President for Sales.

NLMK and Eurocement are also exploring new ways to use fine steelmaking slag in the construction industry, such as the possible substitution of limestone with slag in the production of clinker.

Russia: NLMK Group has completed hot-testing of its new crushing and screening unit for the processing of steelmaking slag at its Lipetsk plant. The project will double the amount of scrap, or ‘metal inclusions‘, extracted from waste and returned to the production process. The new unit will process 2.4Mt/yr of slag, replacing an obsolete unit, which processed 1.7Mt/yr of slag. Metal extraction efficiency at the new unit will be as high as 95%, which will minimise the consumption of iron ore and scrap in pig iron and steelmaking operations through replacement with recoverables. The project had an investment of US$7.2m.

“The new unit will process the entire volume of our steelmaking slag, which is about 2.2Mt/yr, as well as allowing us to eliminate the need to process slag via third parties. The unit will also help us to recycle previously accumulated waste. This Strategy 2017 project is our next step towards increasing the role of recycling in bringing down steelmaking costs and reducing our environmental footprint,” said Sergei Filatov, the managing director of Novolipetsk.

Recovering production waste is one of NLMK’s priorities as part of its operational efficiency improvement efforts. NLMK Group is currently building a new briquetting plant at the Lipetsk plant. Briquettes will be manufactured from a mix of iron ore concentrate and blast furnace slag formed in the process of wet blast furnace gas cleaning. The plant will recycle more than 350,000t/yr of blast furnace waste.
