In the paper, the process of GCr15 bearing steel is improved by optimizing the LF slags and VD furnace process as well as improving the continuous casting process and controlling the rolling temperature. Moreover, its performances were studied. The results showed that the thickness of oxide layer on the surface of GCr15 bearing steel was reduced, the purity of GCr15 bearing steel, the surface quality and hot rolling metallographic structure of wire rod were improved after the process improvement.
