Description
技术领域
本发明涉及一种消失模铸造高铬合金耐磨件余热液淬处理方法。
背景技术
现有高铬合金耐磨件热处理仍旧使用传统方法，将铸成后的铸件再装炉加热到1030摄氏度左右，保温结束后出炉风淬处理，其渗透层深度只有5-7毫米的马氏体组织，耐磨性能低，使用寿命短，而且材料中还必须添加“钼、铜、钒、镍”贵重元素，使生产成本提高30%。
发明内容
本发明的目的在于克服现有高铬合金耐磨件热处理存在的缺点，提供一种利用余热液淬处理高铬合金耐磨件的方法。用本发明方法处理高铬合金耐磨件有三个优点：（1）、不需添加“钼、铜、钒、镍”贵重元素，直接降低30%的生产成本；（2）、不需二次加热，每吨铸件直接减少600度电耗；（3）、马氏体组织淬层深度达到40-50毫米，使用寿命提高40-50%。这是有史以来高铬合金耐磨件热处理的一项新突破，节能效果显著，是一个创举，这是本发明的创造性的表现。所述的高铬合金耐磨件包括：破碎机用的“甩锤、板锤、反击板、衬板”、砖机螺旋。所述现有的高铬合金耐磨件化学成份为：C:2.6-3.2%,Si:0.4-0.8%,Mn:0.4-0.8%,Cr:20-28%,Mo:0.5-1.0%,Cu:0.5-1.0%,V:0.5-1.0%,Ni:0.5-1.0%,S:<0.03%,P:<0.03%,余量为Fe。所述本发明高铬合金耐磨件的化学成份为：C:2.8-3.6%,Si:0.6-0.9%,Mn:0.8-1.2%,Cr:18-24%, Ti:0.15-0.2%,S:<0.04%,P:<0.06%,余量为Fe。
具体实施方式
一种消失模铸造高铬合金耐磨件余热液淬处理方法，其特征在于：（1）、待箱内铸件心部凝固停止负压；（2）、在停止负压后30分钟内出箱进入淬池（此时铸件温度约为1160-1260摄氏度左右）；（3）、待铸件在池内冷却至小于100摄氏度出淬池，经清理后获得高铬合金耐磨件。
