中厚板轧后快速冷却系统设计与应用

Design and application of an accelerated cooling system for plates after rolling

为了完善和丰富钢板的品种和规格,同时提高产品质量和轧制生产效率,针对武钢轧板厂生产线实际情况,设计了一套具有国内领先技术的中厚板轧后快速冷却系统.系统应用工业变频供水、高压水箱水量优化分配及高密度层流等先进技术,同时采用了西门子高性能控制器进行系统综合控制.该系统结构合理,功能完善,控制精度高,已成功投入使用,取得了良好效果.

In order to produce many kinds of products and improve products quality and rolling efficiency, a set of accelerated cooling system with the advanced technology of plates after rolling was designed based on the condition of the plate rolling plant of Wuhan Iron and Steel Corporation, China. The water supply technology by frequency conversion, the optimized distribution technology of water quantity and the high-density laminar flow technology were used in the system. High performance controllers from Siemens were also applied in the system. The system had reliable construction, integrated functions and good control precision, and was successfully used in the plate rolling plant of Wuhan Iron and Steel Corporation.
