摘　　要：磨片是磨浆机的关键零部件。磨片的磨损会使磨浆能量效率、成浆质量和制浆能力下降。对磨片的材料、制造工艺、热处理工艺加以优化,可以延长磨片使用寿命。提高磨片性能的生产措施包括铸造中稀土孕育处理、覆膜砂固化的壳型铸造、铸造后的特殊热处理和铸造磨片的表面改性处理。Disc plate is one of the key parts and components for refiners.The abrasion of disc for refiners will reduce the energy efficiency of refining,qualities of pulp and refining capacity.Optimization on the materials,manufacturing processes and the heat treatment process can extend the service life of disc.Production measures for improving resistance to abrasion of disc for refiners include inoculation with RE during casting,shell casting with coated sand mould,special heat treatment after casting and dealing with surface modification for disc.
