Beschreibung
Zusammenfassung:The invention provides a cooling water circulation control method for strip steel of a normalizing furnace, which is characterized in that the strip steel is cooled in a cooling section of the normalizing furnace in a water spraying manner, and after cooling, water for cooling the strip steel flows back to a turbid circulation system for cooling and filtering treatment. Signals such as the turbid circulation sedimentation tank liquid level, the hot water tank liquid level, the cold water tank liquid level, the cooling tower fan rotating speed, a lifting pump signal, a circulating pump signal and the cold water tank temperature are connected into a main line PLC for automatic interlocking control and alarm control, and stable control over the water temperature and the water quality of the cold water tank can be effectively achieved. And the device can be widely applied to the normalizing furnace with water cooling or water mist cooling. 本发明提供了一种常化炉带钢冷却水循环控制方法,在常化炉冷却段采用水喷淋方式对带钢进行冷却,冷却后,冷却带钢的水回流至浊循环系统进行降温和过滤处理。通
