摘要
南通宝钢钢铁有限公司炼钢连铸单元的纯水循环水系统项目运行前进行设备、管道的清洗预膜处理,保证系统长期稳定运行。纯水密闭循环水系统经水力冲洗、化学清洗、预膜阶段,总历时168 h。通过控制过程指标,较好地完成清洗预膜工作,检测挂片出现明显色晕,腐蚀率满足GB 50050—2007《工业循环冷却水处理设计规范》要求。
In order to ensure the long-term stable operation of the pure water circulation system,the processes of cleaning and prefilming of the devices and pipelines of the said system in steelmaking and continuous casting unit of Baogang Group Nantong Steel Co.,Ltd.were carried out.The total time consumption of the phases： water washing,chemical cleaning and prefilming in pure water closed circulation system was 168 hours.Through the process index controlling,the work of cleaning and prefilming could be well completed;meanwhile,obvious haloing appeared on the hanging pieces for testing,the corrosion rate met the specification of GB 50050—2007 Code for Design of Inidustrial Recirculating Cooling Water Treatment.
