分析了水平连铸的拉坯制度对钢坯表面质量的影响，论述了结晶器入口处齿形初生坯壳的形成机理及其热力学稳定性，提出了水平连铸钢坯齿形初生坯壳迅速平滑化的概念。
The effect of horizontal continuous casting billets on the surface quality of billets was analyzed. The forming mechanism and thermodynamic stability of tooth-shaped primary billets at the entrance of mold were discussed. It was also proposed that the horizontal continuous casting billets should be rapidly smoothed the concept of.
