Optimizing technology and transforming equipment of R9m billet CC in Shiheng Special Steel Plant

In order to improve the quality of superior billet.R9m Billet CC was optimized in Shiheng Special Steel Plant .After optimization,the product structure was optimized,the content of gas and inclusions in billet were resuced. macrostructure of billet was improved .So that the middle crack and bulging deformation were ceased,and the probability of the different side,poriness,shrink hole and superposition of billet was reduced
