锥度微调(法: We have studied the optimum narrow face taper of mold with a target to minimize the cracks of cast product by modifying the taper little by little for various casting conditions and steel grades. 我们已经对结晶器窄面最佳锥度进行了研究，其目标是在不同的连铸条件和浇铸不同钢种的情况下，通过锥度微调法将铸坯裂纹降至最低。)
结晶器保护渣受氧化锆污染(Loss of mold lubrication is due to improper mold slag properties for the casting conditions, erratic steel level control, inadequate mold powder application, mold slag contamination by zirconia or alumina, rapid casting speed increases, or excessively high superheat. 结晶器润滑丧失是由于：结晶器保护渣性能与连铸条件不适应，钢水面控制失稳，结晶器保护渣用量不足，结晶器保护渣受氧化锆或 Al₂O₃ 污染，拉坯速度提高过快或过高的过热度。)
