The Effect of Slag Types and Melting Rate on Electro-Slag Remelting (ESR) Processing
In this research, the influence of chemical composition of slags and the melting rate on the impurity of commercial grade iron in ESR processing has been investigated.The chemical composition and microstructure studies were evaluated, using spectrophotometer,OMand EDX analyses attached to SEM.The results show that ESR process has successfully reduced the amount and size of inclusions. In some c...

متن کاملProduction of Cu-Cr-Zr Alloy Using Electro Slag Remelting Technique (RESEARCH NOTE)
This study focused on the effect of electro slag remelting process (ESR) on microstructure and composition of an as-cast alloy of Cu-Cr-Zr. These observations revealed that applying ESR process results in a more uniform distribution of alloying elements, however a slight aggregation of large precipitates and inclusions existed in as-cast ingot was found. Additionally, impurities like P, S and M...
متن کاملEFFECTS OF ELECTRO-SLAG REMELTING PROCESS (ESR) ON MACROSTRUCTURE AND REFINEMENT OF A MEDICAL GRADE OF STAINLESS STEEL
This study is focused on the effects of electroslag remelting by prefused slag (CaO, Al2O3, and CaF2) on macrostructure and reduction of inclusions in the medical grad of 316LC (316LVM) stainless steel. Results showed that in order to obtain uniform ingot structures during electroslag remelting, the shape and depth of the molten pool should be carefully controlled. High melting rates lead to de...
متن کاملCarbide Structure and Fracture Toughness of High Speed Tool Steels
In the present study, M2 high speed steels were fabricated by using electro-slag rapid remelting process. Carbide structure was analysed and the fracture toughness and hardness were also measured after austenitization treatment at 1190 and 1210C followed by tempering treatment at 535C for billets with various diameters from 16 to 60 mm. Electro-slag rapid remelting (ESRR) process is an advanced...
