来源钢铁厂生产过程中产生的废钢称为“返回废钢”、“自产废钢”或“循环废钢”。钢铁联合企业和普通钢厂自产废钢约为钢产量的15~25%;特殊钢厂达30~50%。废钢主要产生于炼钢车间、铸钢车间和钢的冷加工和热加工车间。随着钢铁生产技术的发展,钢材收得率增加,自产废钢占钢产量的比例有下降趋势。钢铁产品和工制造过程中产生的废钢,约占废钢总量的20~25%,主要为钢料的切头、切尾、切屑、边角料等。各种废旧设备,钢结构件,“报废”的机车、车辆、钢轨、汽车、船舶、工具、用具等,也产生大量“折旧废钢”。它在工业发达国家约占废钢总量的25~30%,占社会上钢材总投放量的1~1.5%。中国当前每年产生的折旧废钢约300万吨。生活用品废旧钢铁如罐头盒、家具和用具等,称为“社会废钢”或“垃圾废钢”,数量有时高达钢材投放量的1%。此外,还有从渣中回收的废钢,积存的废钢块,打捞的沉船等,来源颇为复杂。
