摘　　要：马氏体耐热钢由于其物理特性,在连铸生产过程中易出现表面凹陷、中心疏松及中心缩孔等质量缺陷。通过对马氏体耐热钢在连铸过程中的凝固特点、高温特性和缺陷形成的机理进行分析、研究,优化连铸生产工艺,有效地改善了铸坯质量。Owing to physical characteristics of martensitic heat resistant steel, quality defects easily ap- peared in continuous casting process, such as surface depression, central porosity and central pipe and so on. By studying solidification characteristics and high temperature characteristic of martensitic heat resistant steel in continu- ous casting process, formation mechanism of defects were analyzed. After continue casting technology was optimized, billet quality has improved effectively.
