板坯連鑄結晶器內坯殼厚度及枝晶間距

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

摘要: 通過向結晶器內添加FeS測定了正常工況下結晶器內坯殼的厚度分布.由測得的坯殼厚度分布,分析了結晶器內彎月面參數、凝固系數以及坯殼的凝固速度、溫度梯度和冷卻速度.結果表明,用結晶器內鋼水添加硫方法確定的坯殼厚度分布較為合理.

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.
