一、概述近年来,保温剂在钢铁工业上已得到广泛地应用与充分地重视,国内外冶金工作者已作了大量的工作,并取得了一定的成绩。在炼钢工业中,保温剂的作用尤为重要。为提高钢的质量,转炉出钢中采用截渣操作,使复盖在钢液面上的渣层很薄。为减少盛钢桶及浇注过程中的散热,常在盛钢桶中间包及钢锭模顶部施加足够数量的性能优越的保温剂,以 I. Overview In recent years, the insulation agent in the steel industry has been widely used and fully valued, metallurgical workers at home and abroad have done a great deal of work and achieved some success. In the steel industry, the role of insulation agent is particularly important. In order to improve the quality of steel, slag tapping operation is adopted in tapping of the converter so that the slag layer covering the molten steel surface is very thin. In order to reduce the heat in the ladle and pouring process, a sufficient amount of high temperature insulation agent is often applied to the top of the ladle tundish and the ingot mold
