Smelting Methods and Applications of Stainless Steel Materials
According to the TRIZ theory,the melting and alloying processes of steel were separated in different working stages.The smelting process of EAF+LF+VOD+LF was adopted,and the smelting process of ZG04Cr13Ni4Mo was introduced.The qualified products were obtained with qualified chemical composition,inclusions of liquid steel reaching fine series 1,total oxygen content less than 60 ppm,nitrogen content less than 50 ppm,hydrogen content less than 2 ppm.
