摘　　要：造纸制浆磨片是制浆系统中磨浆工段的核心件和易损件,在制浆生产线中消耗量巨大,同时也是决定纸浆质量的关键零部件。通过对制浆磨片制造厂的实地跟踪,并记录其生产情况,对磨片生产现场存在的问题进行汇总与分析。通过JMatPro软件模拟计算了耐磨材料的相变特征,并以此制定了热处理制度,进行热处理试验,对热处理后的样品使用OM、SEM、EDS等表征和测试手段,研究了制浆磨片的微观组织特征。结果表明:JMatPro模拟计算结果与试验结果基本吻合,通过合适的热处理,磨片材料组织主要为强度和硬度较高的马氏体基体+微米级细小碳化物,这种组织有利于磨片长寿命使用。Paper pulping abrasive disc is a core part and wearing part of the pulping section in the pulping system,which is a huge consumption products in the pulping production line,and also a key part to determine the quality of pulp.The problems existing in the abrasive disc production site are summarized and analyzed through the field tracking of the abrasive disc manufacture factory and recording its production situation.The phase change characteristics of wear-resistant materials were simulated and calculated by JMatPro software,and the heat treatment process was formulated and the heat treatment experiment was carried out.OM,SEM,EDS and other characterization and testing methods were used to study the microstructure characteristics of pulping grinding pieces after heat treatment.The results show that the JMatPro simulation results are basically consistent with the experimental results.Through proper heat treatment,the microstructure of the grinding plate material is mainly martensitic matrix with high hardness+micron fine carbide,which is conducive to the requirement of long service life of the grinding plate.
