鋼鐵廢末煉製熟鐵 國營西北第一機器廠機床上車下來和鉋下來的鐵屑(其中大部爲鋼屑),過去一直沒有利用。今年二三月間,鑄工車間職工會學習西北農具廠熔煉鐵末子的辦法,搞了個煉鐵末的爐子進行熔煉,但也只能煉熟鐵末,不能煉裏面的廢鋼屑和生鐵末,而且煉出來的鐵疙瘩,雜質不能完全清出來。每爐能煉的數量也少。供銷科的技術員范迪清想:廢熟鐵很不好買,又是配機器鑄鐵的一種必需原料,如能依照煉鋼廠煉製木炭熟鐵的辦法,自己來進行熔煉,或許更好。他就把他想的道理,提了個合理化建議。領導
Smelting of iron and steel waste iron smelter down the country’s Northwest Machinery Factory first machine and planing down (most of them steel scrap), the past has not been used. In February and March of this year, the foundry workers’ union learned how to smelt iron ore from the Northwest Farm Machinery Factory and engaged in a smelting furnace at the end of the ironmaking process. However, it was only able to refine the iron scrap at the end and not to refine scrap iron and pig iron at the end. Iron out of the refining pimples, impurities can not be completely cleared. Each furnace can also be a small number of refining. Supply and marketing division technician Fan Di Qingxiang: waste cooked iron is not good to buy, but also with the machine cast iron is an essential raw material, such as in accordance with the practice of steel mills refining wrought iron, their own smelting, perhaps better. He put the reason he thought, made a rational proposal. leadership
