转炉净环水系统自循环改造

Self-circulating Modification of Purified Recirculating Water System for Converter

炼钢一工区转炉净环冷却水用后直接外排，造成废水排放量大，运行费用高等问题。对净环水系统进行改造后实现自循环，可以节约用水，减少鞍钢外排废水量。

The purified recirculating water is directly discharged out after usage at a steelmaking operating zone, resulted in some problems such as big waste water discharge amount, high cost. After the modification, a self circulating system is realized. The purpose of water saving and discharge amount decrease is achieved.
