【Abstract】 The influence of hot rolling technology on austenite grain size in 20MnMoB steel was investigated.The results show that the hot rolling technology is one of important factors determining austenite grain coarsening temperature of 20MnMoB steel.With the increase of relative draught,the austenite grain coarsening temperature of the steel decreases.更多还原
