对16MnDR钢板焊接前的热处理工艺进行了研究。结果表明,厚12mm的16MnDR钢板采用正火工艺为加热温度920℃,保温时间40min(加热速率为1.5～2min/mm)后空冷,可获得良好的组织及优异的力学性能。。
The heat treatment of 16MnDR steel before welding was studied. The results show that the 16MnDR steel plate with thickness of 12mm has good microstructure and excellent mechanical properties by normalizing process with heating temperature of 920 ℃, holding time of 40min (heating rate of 1.5 ~ 2min / mm) and air cooling. .
