我厂11/350水箱拉丝是参观学习无锡钢丝绳厂后,自我武装的。性能、结构良好,运转正常,未经淬火的塔轮是用45号钢铸成,经车加工后成形的。在高速拉丝、连续工作20天左右后起槽,不能生产,需拆下来将槽车平后再用,经车3—4次后,这只塔轮就报废。一台水箱(?)丝机不到2个月,就要报废2对塔轮,近400元左右。报废率太高,不仅浪费资金材料,而且对维修带来很大的不便,影响了生产的进行。为了解决塔轮起槽问题,我们进行了模索。开始在塔轮表面镀铬以增强硬度,因镀的表面层太薄,只有0.1—0.2m/m,所以进行
Our factory 11/350 water tank drawing is self-armed after visiting Wuxi Wire Rope Factory. Performance, good structure, normal operation, unquenched tower wheel is cast with 45 steel, formed by the car after processing. In high-speed drawing, continuous work for about 20 days after the groove, can not be produced, to be demolished to tank flat after reuse, after the car 3-4 times, this tower wheel scrapped. A tank (?) Wire less than 2 months, we must scrap 2 pairs of towers, nearly 400 yuan. Scrap rate is too high, not only a waste of capital materials, but also brought great inconvenience to maintenance, affecting the production. In order to solve the problem of towering tank, we carried out modeling. Began to chrome on the surface of the tower wheel to enhance the hardness, due to plating the surface layer is too thin, only 0.1-0.2m / m, so the
