Abstract: Some of experiment study on the smelting superheat of molten steel was introduced to replule the superheat.The production of composite stainless steel strip by Inversion Casting Technology were introduced. The conclusion was the follows, when the thickness of mother sheet was 2mm, the temperature of mother sheet was 800~850℃ and the smelting superheat was controlled as 10~30℃,the production of composite stainless steel strip would be possible.
