连铸坯凝固末端位置控制研究

Study of controlling liquid pool of continuous casting slab

针对影响连铸坯内部质量的中心缩松、缩孔现象 ,综合运用数值模拟、实验研究、数理统计等方法 ,深入分析了连铸过程的主要工艺因素对铸坯凝固及其凝固末端位置的影响 ,建立了描述各工艺因素与凝固末端位置关系的数学模型 .应用该模型可以合理地控制铸坯的凝固末端位置 。

Centerline shrinkage is one of the main defects of continuous casting slab. Based on the coupling of the numerical simulation and the experimental investigation with the statistical analyses, a mathematical model, describing the relationship of the liquid pool of slab and the technical parameter of continuous casting, is developed to control the liquid pool of slab. By adopting this model, the position of solidification of slab can be controlled.
