【 摘 要 】

In order to research the heat treatment process of hydrogen 12Cr2Mo1VR steel, the small furnace of 50 kg was smelted and rolled. The influence of cooling rate on the microstructure of steel was studied, and the quenching and tempering process of heat treatment was explored. It is found that the austenitizing temperature of heat treatment should be above 875°C in order to obtain better solid solution strengthening effect and avoid two coarsening caused by undissolved phase after quenching. In order to avoid serious M6C phase with coarse coarsening in tempering, the tempering temperature should be higher than 706°C. After comparing the impact properties and tensile properties of different heat treatments, two heat treatment systems were further contrasted, and 970°C WQ + 710°C AC was selected as the best heat treatment system.
