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 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 کاملElectrochemical and Tribological Behaviour of Oxide Dispersion Strengthened Duplex Stainless Steel in Mine Water Environment
Abstract This work investigated the electrochemical and aqueous tribological behavior of hot pressed 2205 duplex stainless steel (DSS). DSS sintered composites of different volume percent (% vol) of partially stabilized zirconia (PSZ) was developed using powder metallurgy (PM) technique. Electrochemical behaviour was studied at room temperature, using open circuit potential and potentiody...
متن کاملVacuum Induction Melting
MELTING UNDER VACUUM in an induction-heated crucible is a tried and tested process in the production of liquid metal. It has its origins in the middle of the 19th century, but the actual technical breakthrough occurred in the second half of the 20th century. Commercial vacuum induction melting (VIM) was developed in the early 1950s, having been stimulated by the need to produce superalloys cont...
