| 摘 要： | 精锻机锻造高碳铬轴承钢时存在网状碳化物不易破碎、锻件合格率低的问题。通过采用锻后雾冷+正火雾冷+球化退火的热处理工艺,将轴承钢锻件网状碳化物的合格率从66%提高至93.4%。

| Abstract: | While forging the high-carbon chromium bearing steel by the finish forge press,there still remains the issues that the carbide network can not be crushed with the low qualification rate.By means of the heat treatment process such as mist cooling after forged + normalizing mist cooling + spheroidal annealing,in this case,the qualification rate of carbon network of the bearing steel forging shall be improved from 66% to(93.4%). |
