一种新型钢水保温剂日本新近研究出一种新型的保温剂，这种保温剂的组成为：１０％～４０％的消石灰或钙渣，３０％～６０％的粘结剂，１０％～５０％的ＭｇＯ。备组成物的粒度均≤１ｍｍ。这种保温剂可用于盛钢桶等钢液的保温，其保温性能优良。该保温剂现已取得了日本的... A new type of molten steel thermal insulation Japan recently developed a new type of thermal insulation agent, the composition of this thermal insulation: 10% to 40% of the slaked lime or calcium slag, 30% to 60% of the binder, 10% to 50 % Of MgO. Prepared composition of the particle size are ≤ 1mm. This insulation agent can be used for holding molten steel such as ladle, the insulation performance is excellent. The thermal agent has been made in Japan ...
