连铸过程中,覆盖中间包钢液面的保温剂应当满足下列要求:使钢水和大气隔绝,以减少热损失;确保钢水不被二次氧化,并能创造吸附上浮非金属夹杂物的最佳条件;另外,在钢液面上形成的渣应不会对钢包衬产生侵蚀作用。选择保温剂化学成分时,最重要的是考虑其所形成的渣的粘度。渣粘度
In the continuous casting process, the thermal insulating agent covering the tundish surface should meet the following requirements: Insulate the molten steel from the atmosphere to reduce heat loss; ensure that the molten steel is not reoxidized and create the best adsorption of floating non-metallic inclusions Conditions; In addition, the slag formed on the surface of the molten steel should not have erosion of the ladle lining. When choosing the chemical composition of the insulation, the most important thing is to consider the viscosity of the slag it forms. Slag viscosity
