Development of GCr15SiMn Steel for Rolling Mill Bearings
This paper introduces the development and key processes of GCr15SiMn steel for rolling mill bearings.The process adopts vacuum degassing+continuous casting+continuous rolling,and through technologies such as low harmful element control,refining and efficient deoxidation,continuous casting and light reduction,intermediate ladle induction heating,and controlled rolling and controlled cooling,the steel for rolling mill bearings has the characteristics of high purity,low harmful element content,and high tissue uniformity,which can meet user requirements and achieve international advanced level of product quality.
