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

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.
