随着国民经济的迅速发展,钢材的需要量日益增多。当前,钢材供应紧张,供需矛盾比较突出。要解决钢材供应紧张的状况,除了开采矿石和进口矿石增加钢材产量外,最主要的一条就是要充分回收和合理利用废钢铁。我国每年产生的废钢铁约有2500万吨,其中40%的废钢铁基本上由产生废钢铁的企业自行消化。每年大约有1500万吨废钢铁要通过流通环节实行再分配,占我国钢 With the rapid development of the national economy, the demand for steel is increasing. At present, the tight supply of steel, the contradiction between supply and demand is more prominent. To solve the tight supply of steel, in addition to mining ore and imported ore to increase steel output, the most important one is to fully recover and make rational use of scrap steel. China produces about 25 million tons of scrap every year, of which 40% is basically digested by enterprises that generate scrap iron. Each year about 15 million tons of scrap steel to be redistributed through circulation, accounting for China’s steel
