Abstract

The invention provides a hot-rolled strip steel laminar cooling device and a control method thereof. The hot-rolled strip steel laminar cooling device and the control method thereof are used for solving the problem of water accumulation of a steel strip in the prior art. The hot-rolled strip steel laminar cooling device is located between a finishing mill group and a coiling machine and comprisesa middle cooling section and a tail end side water spraying group, the middle cooling section is used for cooling the steel strip, and the tail end side water spraying group is also used for cooling the steel strip. The tail end side water spraying group comprises at least one water spraying nozzle arranged on the side face in the steel strip conveying direction, the purging angles of the water spraying nozzles are larger than or equal to the width of the steel strip, the water spraying directions of the water spraying nozzles deviate to the steel strip conveying direction or the direction opposite to the steel strip conveying direction, and an acute angle is formed between the water spraying directions of the water spraying nozzles and the left-right direction. Accumulated water of the steel strip can be swept away.

Description

technical field [0001] The invention belongs to the field of steel production equipment, in particular to a laminar flow cooling device for hot-rolled strip steel and a control method thereof. Background technique [0002] In the hot-rolled strip steel production line, laminar flow cooling has become an indispensable process link in the production of hot-rolled strip steel, and the ability of laminar flow cooling directly determines the performance of the product. The basic principle of laminar cooling: by controlling the opening number of the headers of the laminar cooling system, the flow rate of the headers and different control strategies, the cooling speed of the strip after rolling and the final temperature entering the coiler are controlled, thereby improving the metallographic profile of the strip. organization and performance. [0003] The quality of laminar cooling is directly reflected in the coiling temperature control accuracy. The coiling temperature is one o...
