连铸坯内部中心缩松、缩孔是影响铸坯内部质量的主要缺陷之一。本文综合运用数值模拟、实验研究、数学推导等手段 ,提出了描述连铸坯中缩缺陷形成可能性大小的连铸坯中缩敏感系数。并以中缩敏感系数为桥梁 ,建立了工艺因素与中缩缺陷的关系 ,为进一步实现连铸工艺的计算机优化奠定了基础
One of the main defects that affect the internal quality of the slab is shrinkage and shrinkage of the inner center of the slab. In this paper, we use the numerical simulation, experimental research and mathematical derivation to propose the shrinkage-sensitive coefficient in the continuous casting slab, which describes the possibility of shrinkage defects in the continuous casting slab. The relationship between the process factors and the shrinkage defects was established by using the medium shrinkage sensitivity coefficient as a bridge, which laid the foundation for further computer optimization of the continuous casting process
