为解决热处理和加热设备能力不足问题,永济电机厂自己设计、制造了一台具有保护气氛及高温性能(1200℃)的90kW台车电阻炉。此炉用高强度轻质砖砌筑、保温层为硅酸铝纤维,台车进出均为电控并附有自动收线装置,工件进出炉采用吊车,大大减轻了工人劳动强度。此炉可代替2台35kW渗碳炉对螺钉加热,产量比前提高3倍,有效地缓解热处理设备能力不足的矛盾。可节能15％,而且为工厂节约4.5万余元的设备购置费。
In order to solve the problem of insufficient heat treatment and heating equipment capacity, Yongji Electric Works designed and built a 90kW trolley resistance furnace with a protective atmosphere and high temperature performance (1200 ℃). The furnace is made of high-strength lightweight brick masonry, the insulation layer is aluminum silicate fiber. The trolley is both electrically controlled and equipped with an automatic wire take-up device. The workpieces are transported in and out of the furnace by crane, greatly reducing the labor intensity of workers. This furnace can replace the two 35kW carburizing furnace heating screw, the output increased three times than before, effectively alleviate the heat treatment capacity of the lack of contradictions. Can save 15%, but also for the factory to save 45,000 yuan of equipment purchase costs.
