Abstract

The state of steel-melting production in Ukraine in 1991–1995 is considered. About 50% of the steel is produced in open-hearth furnaces. The imperfect structure of steel-melting production, the low quality of the refractory materials used, and the unstable operating conditions of steel-melting equipment determine the high specific consumption of magnesia refractories which exceeds that in the leading industrial countries by a factor of 2–3. The volume of out-of-furnace treatment of steel by the LF, AOD, ACEA—CKF, and VKO processes does not exceed 1% of the total yield.
