技术领域technical field

本发明涉及破碎机技术领域,尤其涉及一种动锥体制备用耐磨材料、动锥体及动锥体的制备方法。The invention relates to the technical field of crushers, in particular to a spare wear-resistant material for a movable cone, a movable cone and a preparation method for the movable cone.

背景技术Background technique

圆锥破碎机可广泛应用于各黑色、有色、非金属矿山及砂石料等工业领域,圆锥破碎机依靠动锥体和破碎壁的摩擦,来破碎岩石。动锥体需要承受岩石的冲击和磨损,因此,要求动锥体椎体内侧有较高的强度和耐冲击性,其表面还应具有很高的硬度和耐磨性。Cone crushers can be widely used in various industrial fields such as black, non-ferrous, non-metallic mines and sand and gravel materials. Cone crushers rely on the friction between the moving cone and the crushing wall to crush rocks. The dynamic cone needs to withstand the impact and wear of the rock. Therefore, the inner side of the cone body is required to have high strength and impact resistance, and its surface should also have high hardness and wear resistance.

目前,动锥体材料通常选用铸钢、高锰钢、高铬铸铁等,动锥体机加工后,工作表面还需要进行热处理,以增加动锥体工作面的耐磨性。然而,直接采用整体制造动锥体或经一定热处理工艺进行整体或局部强化处理的动锥体工作面耐磨性能及耐冲击性能较差,从而导致动锥体常因过早磨损而失效,进而破坏圆锥破碎机的机动性。At present, the material of the moving cone is usually cast steel, high manganese steel, high chromium cast iron, etc. After the moving cone is machined, the working surface needs to be heat treated to increase the wear resistance of the working surface of the moving cone. However, the wear resistance and impact resistance of the working surface of the dynamic cone that are directly manufactured as a whole or through a certain heat treatment process for overall or local strengthening are poor, resulting in the failure of the dynamic cone often due to premature wear, and then Impairs the mobility of the cone crusher.
