　　钢铁企业在生产过程中需要大量的新水资源，同时又不可避免地在外排废水过程中对水资源造成污染。因此在钢铁生产过程中应尽量增加水的利用率和循环水浓缩倍数。
　　为达到节水目的，钢铁工业根据工序对水质要求不同，一般采用分质供水、分级串联利用。
　　In the manufacturing process of iron and steel industry, there need a great deal of fresh water, as well as, drain the waste water to pollute resource of water unavoidably. It is very essential to make the most of utilization ratio of water and cycles of concentration of circulating water.
　　According to the demand of working procedure, it generally adopt water supply for different water quality or series classification.
