【摘要】：以土木機(jī)械攪拌機(jī)襯板材料ZG85Cr2MnMo為研究對象,在不同條件下進(jìn)行熱處理,熱處理后對其硬度、淬透性、沖擊韌度及耐磨性進(jìn)行分析。結(jié)果表明:隨淬火溫度的升高,土木機(jī)械攪拌機(jī)襯板材料硬度先變大后減小,在880℃時(shí)達(dá)到最大值828 HV,且該溫度下淬火試樣的淬透性及淬硬性良好;隨回火溫度的升高,硬度逐漸下降,沖擊韌度不斷上升,試樣在400~500℃回火獲得較高硬度的同時(shí)已具備較好的沖擊韌度;綜合硬度、沖擊韌度和耐磨性分析,土木機(jī)械攪拌機(jī)襯板材料ZG85Cr2MnMo的最佳熱處理工藝為880℃加熱油淬,500℃回火,該熱處理工藝下襯板材料可以獲得較好的綜合性能。
[Abstract]:Taking ZG85Cr2MnMo as the research object, the hardness, hardenability, impact toughness and wear resistance of the lining board of civil machinery mixer were analyzed after heat treatment under different conditions. The results show that with the increase of quenching temperature, the hardness of lining board of civil machinery mixer increases first and then decreases, reaches the maximum value of 828 HV, at 880C, and the hardenability and hardenability of the quenched sample are good at this temperature. With the increase of tempering temperature, the hardness decreases gradually, and the impact toughness increases continuously. The high hardness obtained by tempering at 400? 500 鈩，
