In recent years, the controlled cooling technology after rolling of the medium plate is receiving more and more attention. Steel enterprises put forward higher cooling speed and cooling uniformity requirements for producing high-performance products, and the traditional laminar flow cooling device cannot meet the increasingly improved cooling performance requirements of the steel enterprises.

The conventional laminar flow cooling equipment generally improves the heat exchange efficiency by means of encrypting a collecting pipe, increasing the size of a water outlet of the collecting pipe and the like, for example, an enhanced laminar flow cooling device developed by a certain domestic unit is an optimization device of a common laminar flow cooling device, and water quantity of an upper cooling water nozzle is about 2 times that of the common laminar flow cooling device by encrypting the upper cooling water nozzle on the same cooling distance. Such structures are still laminar cooling from a cooling mechanism. Due to the cooling mechanism, the technical realization cannot realize a large cooling speed, and the problem of uneven cooling of the steel plate under the condition of large flow cannot be solved.

Therefore, the following two problems still exist in the device: firstly, the cooling capacity is not enough, and secondly, the plate shape is poor under the condition of large cooling strength. The Super-OLAC of the Japan JFE company and the MULPIC medium plate ultra-fast cooling equipment developed by the Siemens VAI company are representatives of similar devices abroad, and from the use experience of the similar devices in domestic steel enterprises, the similar devices abroad have some defects, mainly the weak plate type control capability and the ladle area defect easily generated when certain steel grades are produced.
