Lignite-coke briquets in ferroalloy production
Tóm tắt
Kansko-Achinsk 2B and 3B coal is of interest not only as a fuel but also as a raw material for the production of metallurgical reducing agents. Theoretical and practical aspects of the manufacture of briquets based on medium-temperature coke (thermocoke) produced from Berezovsk 2B lignite and their use in ferroalloy smelting are considered. The new material is compared with metallurgical coke. Keywords: coke, coal, medium-temperature coke, reduction, silicon, chromium, shaft electrofurnaces, gas liberation, ferroalloys
