摘　　要：由于马氏体不锈钢的物理特性，使得连铸过程中存在柱状晶发达、中心疏松、缩孔及表面凹陷严重等问题。针对上述情况，连铸过程中针对该钢种凝固特点、高温物理特性等方面进行了研究，解决了马氏体不锈钢浇铸过程中的工艺问题，保证了产品的质量。The developed columnar crystals, center porosity ,shrinkage cavity and surface quality of martensitic stainless steel are caused by special physical properties. The study of solidification and elevated temperature physical properties of martensitic Stainless Steel was carried out. The preliminary solution was got to solve these technical problems, and the product quality was enhanced.
