Refractory concrete parts for edging the walls of soaking pits

Conclusions The technicoeconomic desirability of replacing chamotte brick in the edge of soaking pits with concrete parts of bauxite or of a mixture of commercial grade chamotte and silicon carbide part scrap using high-alumina cement was shown. The life of the upper structure of the soaking pit doubled, the time for repair of this element of the lining was reduced by more than 10 times, and the heavy bricklaying work was replaced by less laborious assembly work.
