电弧炉炼钢过程中,每道工序的操作几乎是重体力劳动,为减轻劳动强度,搞了辅助设备,如炉顶加料、电磁搅拌等,辅助料加料同样是一项繁重体力劳动。如10吨电炉,每炉出钢水18～20吨,仅加入的合金量3～5吨,石灰、萤石、铁矿石等大量的渣料要往炉内加,每炼一炉钢,工人们汗流夹背,腰疼腿酸。因 Electric arc furnace steelmaking process, the operation of each process is almost heavy manual labor, in order to reduce labor intensity and engage in auxiliary equipment, such as the top feeding, electromagnetic stirring, auxiliary material feeding is also a heavy manual labor. Such as 10 tons of electric furnace, each furnace tapping 18 ~ 20 tons, only adding the amount of 3 to 5 tons of alloy, lime, fluorite, iron ore and other large amount of slag to be added to the furnace, each refining a furnace steel, workers Sweat clip back, back pain leg pain. because
