铲斗,铲运机刮板、斗齿、矿车轮子及锤碎机等都是需要经常维护的易磨损机件。采用表面耐磨堆焊及堆焊可延长使用寿命。本文说明了堆焊工艺在采矿工业及破碎机中的应用,并讨论了现场焊接程序。较详细地说明了,用高应力磨损试验为锤碎机锤子选择表面耐磨堆焊材料及堆焊材料。对所选合金进行现场试验确定其性能。维修记录已表明这大大地节省了时间和降低了成本。总结了合金坑磨强度与硬度、加工硬化、成本及微观结构之间的关系。 Buckets, scoop scrapers, bucket teeth, mine wheels and hammer pulverizers are often worn parts that require frequent maintenance. Adopt the surface wear-resistant surfacing and surfacing can extend the service life. This article describes the application of surfacing technology in the mining industry and crushers, and discusses on-site welding procedures. Described in more detail, high-stress wear test hammer hammer for the selection of surface wear-resistant surfacing materials and surfacing materials. The selected alloy field test to determine its performance. Maintenance records have shown that this saves significant time and costs. Summarized the relationship between the strength of the alloy pit grinding and hardness, work hardening, cost and microstructure.
