摘要
研究了热处理工艺对中铬抗磨铸钢组织和性能的影响，确定了合理的热处理工艺参数。经热处理后中铬抗磨铸钢的性能为硬度ＨＲＣ≥６０，冲击韧性ａｋ≥２０Ｊ／ｃｍ２。
Studies the effect of heat treatment on the microstructure and properties of medium chromium wear resistant cast steel and gives the rational procession parameters of heat treatment.It gets HRC 60 and impact toughness(ak)more than 20 J/cm 2 after being subject to heat treatment.
