今年我国废钢需求量将达到3900万吨,可供废钢资源3700万吨,供需平衡存有200万吨缺口将靠进口解决,由此可见钢铁行业所需废钢铁将来自于国内外两大市场。但当前冶金企业与供货单位之间,所依据的标准回炉碳素废钢分类及技术条件(GB4223—84),难于适应这两大市场。 This year, the demand for scrap in China will reach 39 million tons, 37 million tons for scrap steel, and 2 million tons will remain in the balance of supply and demand. This shows that the scrap steel needed by the steel industry will come from both domestic and overseas markets. However, between the current metallurgical enterprises and suppliers, based on the standard classification of scrap carbon scrap and technical conditions (GB4223-84), it is difficult to adapt to these two major markets.
