当前,我国钢铁工业转型升级的两个核心,绿色转型和产品升级,都与废钢消费直接相连。据专家测算,用废钢代替生铁炼钢,平均吨钢可节约铁矿石近1.67吨,减少能源消耗350千克～400千克标煤,减少CO_2、SO_2等废气排放86%,减少废水排放76%、废渣排放72%。废钢铁的利用在资源循环利用和节能减排方面效果明显。根据废钢协会对我国重点钢企统计:今年上半年综合炼钢废钢单耗为95公斤,
At present, the two cores of the transformation and upgrading of China’s steel industry, green transformation and product upgrading, are all directly linked to the consumption of scrap steel. According to experts’ calculations, using scrap instead of pig iron and steelmaking, the average tonne of steel can save nearly 1.67 tons of iron ore and reduce energy consumption by 350kg ~ 400kg of standard coal, reduce 86% of emission of CO_2 and SO_2, and reduce 76% Waste discharge 72%. The utilization of scrap steel has obvious effect in resource recycling and energy conservation. According to the Scrap Association statistics on China’s key steel enterprises: the first half of the comprehensive steel scrap scrap unit consumption of 95 kg,
