Research Status of High Speed Steel for Rolls

High speed steel rolls,widely used in the steel rolling industry,are characterized of excellent hardness,high temperature properties and wear resistance.The main elements and their effects,the characteristic of carbides in high speed steel rolls as well as production technologies and the characteristic of high speed steel rolls are summarized in this paper.The recent research on the effect of modification on the microstructure and mechanical pro-perties of high speed steel rolls are reviewed.For the improvement in research and application of high speed steel rolls,study on chemical composition matching,heat treatment technology,application characteristic,microstructure transformation and computer control for modification of high speed steel rolls should be emphasized.
