目前电弧炉电极升降绝大多数仍采用钢丝绳卷筒系统。在操作过程中常常会发生钢丝绳松脱现象(即通常所说的钢丝绳掉道),一旦钢丝绳掉道就得停电抢修,延长熔炼时间,浪费电力,工人们还得冒着酷热到炉顶上进行繁重的体力劳动,弄得汗流浃背,浑身油泥。我厂电炉工人李国祥等同志破除迷信,解放思想,自己动手,土法上马,只花了10多元钱,制成钢 At present, most of the electric arc furnace electrode lift still use wire rope reel system. Rope unscrewing often occurs during operation (commonly referred to as wire rope drop-off), and once the wire rope goes off, it has to be repaired by a power failure, lengthening the smelting time and wasting power. Workers also have to heat up to the top of the furnace Heavy manual labor, made sweat, covered with mud. Our electric furnace workers Li Guoxiang and other comrades to get rid of superstition, emancipate the mind, do it yourself, native law launched, only spent more than 10 yuan of money, made of steel
