The Influence of Heat Treatment Process on the Microstructure and Properties of Large SAG Mill Cylinder Liner
In response to the frequent maintenance and replacement of SAG mill liners,the paper discusses the influence of heat treatment process on the microstructure and properties of large SAG mill cylinder liners to extend the service life of the mill,and analyzes the influence of different quenching and tempering temperatures on the microstructure and mechanical properties of the materials by optimizing the heat treatment process of chromium molybdenum steel liner.The experimental results show that under the conditions of quenching at 920℃and tempering at 560℃,the chromium molybdenum steel liner exhibits the best comprehensive performance,with a hardness of 45HRC and an impact toughness of exceeding 45 J/cm2.
