我国废钢不足这个矛盾,短期内尚不能解决.据冶金工业部有人估计:每生产100万吨钢材大约只产生20万吨废钢,并且将来在采用连续铸锭后,产生的废钢还要少.由于废钢缺少,现有的平炉不得不加入大量生铁(大约是80%生铁,20%废钢).在机械工厂中,看它产品的性质,或多或少能从金属备料、机械加工、锻件切头, According to estimates from the Ministry of Metallurgical Industry, only about 200,000 tons of scrap steel are produced per 1 million tons of steel and less scrap will be produced in the future when continuous ingots are used in the future There is a lack of scrap, and existing open hearths have had to add large amounts of pig iron (about 80% pig iron and 20% scrap). In a machine shop, look at the nature of the product, more or less cut from metal stock, machining, forgings ,
