METHOD FOR PRODUCTION OF CARBIDES

FIELD: metallurgy. SUBSTANCE: process of melting of carbide block is carried out in two stages. In the first stage, use is made of pelletized charge, in which amount of reducing agent exceeds that of required by stoichiometry by 3-10%, and in the second stage, use is made of pelletized charge in whi...

Summary:FIELD: metallurgy. SUBSTANCE: process of melting of carbide block is carried out in two stages. In the first stage, use is made of pelletized charge, in which amount of reducing agent exceeds that of required by stoichiometry by 3-10%, and in the second stage, use is made of pelletized charge in which the amount of reducing agent exceeds the required amount by stoichiometry by 0.1-2.5%. EFFECT: reduced power consumption, increased yield of satisfactory product and higher efficiency. 4 tbl Сущность изобретения: процесс выплавки блока карбида осуществляют в две стадии: на первой стадии используют окомкованную шихту, в которой восстановителя на 3-10% больше, чем требуемого его по стехиометрии, а на второй - окомкованную шихту, в которой восстановителя на 0,1 - 2,5% больше, чем требуется его по стехиометрии. 4 табл.
