Effect of Triple Smelting Process on the Purity and Microstructure of 9Cr18Mo Bearing Steel

摘要：

　　In order to improve the purity of bearing steel, the VIM+ESR+VAR triple smelting process was used to smelt 9Cr18Mo stainless bearing steel.The content of harmful elements, non-metallic inclusions and microstructure of the steel were studied.The results show that, the content of harmful elements of the steel is very low.A fairly small number of non-metallic inclusions are uniformly distributed and fine.The purity of the steel reaches a higher level.After thermal processing and heat treatment, the microstructure of the steel is the same as 9Crl8Mo bearing steel smelted by normal process, but the primary carbides in the steel is more uniform distribution and finer.
