摘要: 本实验以平果拜耳法赤泥和锰矿结合提炼还原出的中锰铸铁作为原料，分别对试样使用不同温度进行淬火，并配合低中高温回火的热处理后观察其组织，研究中锰铸铁的硬度和耐磨性。实验结果表明中锰铸铁最佳热处理工艺为850℃淬火200℃回火，热处理后通过显微镜观察得到以回火马氏体为主，同时存在贝氏体、残余奥氏体以及少量碳化物的试样金相组织，其硬度较低易于加工，磨损后失重量小，耐磨性好。在相同淬火温度下，随着回火温度的增加，试样的硬度降低，耐磨性能减弱。淬火温度的变化对试样的力学性能的影响相对较小。
Abstract: In this experiment, the medium manganese cast iron produced by the combination of red mud and manganese ore from Pingguo Bayer process was used as raw material, and then melted and cut into samples, the manganese content is about 5.36%. The hardness and wear resistance of medium manganese cast iron were studied after quenching at 800˚C, 850˚C and 900˚C and tempering at 200˚C, 400˚C and 600˚C respectively. The results show that the best heat treatment process of medium manganese cast iron is 850˚C quenching and 200˚C tempering. After heat treatment, the microstructure of the sample is mainly tempered martensite, with bainite, retained austenite and a small amount of carbide. It has low hardness and is easy to process. It has small weight loss and good wear resistance after wear. At the same quenching temperature, with the increase of tempering temperature, the hardness and wear resistance of the sample decrease. The change of quenching temperature has little effect on the mechanical properties of the samples.
