Conclusions Under the severe service conditions of the ladles used in the production of ferrosilicon (temperature 1900°C and the duration of teeming 2.5 h), chamotte linings do not possess sufficient life. In this case, mullite present in chamotte decomposes to form corundum and a glass phase which, in turn, interacts with carbon to form silicon carbide and cementite. The formation of a working zone consisting of silicon carbide, cementite, and calcium hexa-aluminate improves the service life of the lining to some extent. Monolithic self-densifying carbon linings were used for the first time for lining the ladles used in the production of ferrosilicon. Their application led to a five-fold improvement in the life of the lining as compared to the life of the chamotte linings. Such an improvement owes to the formation of a dense layer of SiC and Fe3C.
