Research on Phase Change Calculation and Heat Treatment of Stainless Steel Material for Pulping Abrasive Disc
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.
