一、引言钢液凝固是由热传递和液体对流运动这两个基本现象控制的。连铸是铸坯在运动中带有很长液相穴的凝固过程。液相穴内液体的运动对于过热度的消除、凝固结构和成分
I. INTRODUCTION The solidification of molten steel is controlled by the two basic phenomena of heat transfer and liquid convection. Continuous casting is the solidification of slab with a long liquid phase in motion. The movement of liquid in the liquid cavity eliminates the superheat and solidifies the structure and composition
