废钢是炼钢的重要原料,多年来,一般是处在供过于求的状态。库存逐年上升,如1982年底,上海冶金企业的废钢库存达40万吨,是历史最高的数字,为降低库存,也为降低产钢成本,几年来各厂都实行多吃废钢有奖的办法,到1983年一季度很快就倒转为供不应求,且日趋严重,如83年至12月上钢五厂、一厂都由于废钢供不应求而增加了生铁的消耗一万五千多吨,从而使钢锭成本回升。至1983年底上海冶金企业废钢的库存仅为10万吨,比82年降低了3/4,废钢供应困难,不仅是在上海,在全国均已成为炼钢生产中的一个问题。
Scrap is an important raw material for steelmaking. Over the years, scrap is generally in oversupply. Inventories increased year by year, such as the end of 1982, the Shanghai metallurgical enterprises scrap inventories reached 400000 tons, is the highest in history, in order to reduce inventory, but also to reduce the cost of producing steel, the plant over the past few years to eat more scrap prizes, In the first quarter of 1983, the demand for iron was rapidly reversed and became increasingly serious. For instance, the first five factories and the first one in 1983 and December all increased the consumption of pig iron by more than 15,000 tons due to the shortage of scrap, making the cost of steel ingot Pick up. By the end of 1983, the stock of scrap in Shanghai metallurgical enterprises was only 100,000 tons, a decrease of 3/4 over 82 years. The supply of scrap was difficult, not only in Shanghai, but also in the whole country as a problem in steelmaking.
