零件在箱式电炉中加热调质时,手工操作劳动强度大,往往三四个人操作还累得满头大汗。去年我们在炉门前建成一地下水槽(见图),解决了这个问题,具体做法如下: 在距箱式炉炉门前1米处,挖一1.2×1.2×1.5(深)米的槽,槽底用混凝土浇注而成,四周用普通砖彻成槽壁,再抹上水泥即成。槽上盖一厚5毫米的钢板,钢板上切一60×60毫米孔,用摆皮板盖上,另外再设一挂钩 Parts heating in the box-type electric furnace when the manual operation of labor-intensive, often three or four individuals are also tired of sweating profusely. Last year we built an underground tank in front of the oven door (see photo) to solve the problem by digging a 1.2 x 1.2 x 1.5 (deep) meter tank at a distance of 1 meter from the front of the box oven door, The bottom of the tank is made of concrete, surrounded by ordinary brick wall into the tank, and then cast the cement Serve. Slot cover a thick 5 mm steel plate, cut a 60 × 60 mm hole, with a swing plate cover, and then set a hook
