摘要
研究了当Cr12铸铁的铸态组织有珠光体时,热处理工艺对其组织和性能的影响。通过试验,得出了在1050℃淬火时,淬火硬度值最高;回火温度升高,显微组织也发生变化,硬度提高,耐磨性较好。在作为磨球使用时,最佳处理工艺为1050℃淬火+400～500℃回火。
The influence of heat treatment process on structure and properties of Cr 12 cast iron with pearlite existing in its as-cast structure was studied. The test showed that the highest hardness was obtained when quenching temperature was 1 050 ℃. As the tempering temperature increased, the microstructure also changed and the hardness increased so the wear resistance was improved. When this type of cast iron used for producing grinding balls the optimal treatment is quenching at 1 050 ℃ + tempering at 400 ℃～500 ℃.
