Shell Thickness Distribution in Mold and Space between Dendrites in the Shell of Continuous Casting Slab

摘要: 通过向结晶器内添加FeS测定了正常工况下结晶器内坯壳的厚度分布.由测得的坯壳厚度分布,分析了结晶器内弯月面参数、凝固系数以及坯壳的凝固速度、温度梯度和冷却速度.结果表明,用结晶器内钢水添加硫方法确定的坯壳厚度分布较为合理.

Abstract: The distribution thickness of steel shell was gotten by added the sulfur into the mould of continuous casting slab. Use the steel shell thickness, the shape of meniscus, soildification coefficient of mould, solidification velocity and the gradient of temperature in shell were calculated.
