摘要：
A refractory for steel casting comprising, based on the total weight of the refractory in each case, 5-80% by weight of ZRM, 10-40% by weight of carbon powder, 0-20% by weight of one or more of SiC, Si.sub.3 N.sub.4, metallic silicon and ferrosilicon, 0-30% by weight of fused silica and 0-60% by weight of alumina powder containing at least 70% by weight of Al.sub.2 O.sub.3 based on the total weight of the alumina powder. The ZRM includes the main mineral phase consisting of mullite, baddeleyite and corundum and having the chemical composition consisting of 25-85% by weight of Al.sub.2 O.sub.3, 10-70% by weight of ZrO.sub.2 and 5-25% by weight of SiO.sub.2. A process for producing the refractory for steel casting.
