4 Classification and grades

Refractory castables for steel rolling heating furnaces are divided into refractory castables for working linings and refractory castables for thermal insulation linings according to their use positions. Refractory castables for working linings are divided into ZJ-40, ZJ-50, ZJ-60, ZJK-60, ZJ-65, ZJS-65, ZJ-70 seven grades; refractory castables for thermal insulation lining are divided into ZJQ-0.6, ZJQ-0.8, ZJQ-1.0, ZJQ-1.3, Five grades of ZJQ-1.5. Among them, Z, J, K, S, and Q are the first characters of the first Chinese pinyin of "rolling heating furnace", "casting material", "anti-burst", "water-cooled pipe" and "light". Mother; the number after ZJ, ZJK, ZJS represents the mass fraction of the product alumina, the number after ZJQ represents the volume density of the product.
