索道是矿山运输的重要设备,其托索轮在长期生产运行中,受到严重的磨损,而且索道对托索轮的需要量很大。为解决这一困难,采取了电弧堆焊方法修复,效果很好。经车床加工后,保证了尺寸要求,满足了生产需要。焊补后的托索轮要求具有耐磨性和可加工性。托索轮为45号铸造锰钢,堆焊后不能变形并保证元周径向尺寸的一致。为了保证上述质量要求,采用了两种堆焊材料:第一种是距加工表面0.5～1毫米以下的
Cableway is an important equipment for mine transportation. Its cable pulley suffered serious wear and tear in the long-term production operation, and the ropeway required a large amount of the cable. In order to solve this problem, the method of arc surfacing has been adopted and the effect is very good. After the lathe processing, to ensure the size requirements to meet the production needs. Weld repair after the request of the cable has wear resistance and workability. Torso wheel 45 cast manganese steel, after welding can not be deformed and ensure that the perimeter of the radial size of the same. In order to ensure the above quality requirements, using two surfacing materials: the first is from the processing surface of 0.5 to 1 mm below
