炼钢厂磁选尾渣处理系统工艺改造

Technology Modification of Magnetic Separation Tailings Processing System for Steel-making Plant

针对昆钢炼钢厂60万t／年钢渣磁选处理生产线使用过程中，斜板浓密机、盘式真空过滤机处理能力不足，尾渣排放困难，污水直接外排，严重污染环境等问题，对磁选尾渣处理工艺、设备进行改造，将水力旋流器、厢式隔膜自动压滤机应用在钢渣磁选尾渣处理系统中，改造后取得显著的经济效益和社会效益。

In steel slag magnetic separation processing line of 600,000 t/y of Kungang steel-making plant, lamella thickener and disk vacuum filter capacity insufficient, tail-slag discharge difficult, direct discharge sewage, causing severe environmental pollution, the processes and equipment were then improved, with using hydrocyclone and diaphragm pressure filter, and the economic and social benefit are great
