Abstract

The invention discloses a cooling device for a rolling mill. The cooling device comprises a water tank, a water inlet pipe, a driving device, an upper side cooling device and a lower side cooling device; the upper side cooling device is used for cooling the upper surface of a hot-rolled steel plate steel strip in a cooling section; the lower side cooling device is used for cooling the lower surface of the hot-rolled steel plate steel strip in the cooling section; each of the upper side cooling device and the lower side cooling device comprises water inlet branch pipes, a flow dividing device, a plurality of rows of cooling water pipes and nozzles; and the water tank is connected with the water inlet pipe, the water inlet pipe is provided with the driving device, the flow dividing device is arranged between the water inlet pipe and the water inlet branch pipes, the water inlet branch pipes are connected with cooling water pipes, the cooling water pipes are perpendicular to the running direction of the hot-rolled steel plate steel strip, and cooling water pipe bodies are provided with the multiple nozzles. The cooling device guarantees the cooling uniformity of the rolling mill and is good in cooling effect.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a cooling device for a rolling mill. Background technique [0002] The finishing rolling production line of iron and steel enterprises must use the strip cooling device. Its main function is to rapidly cool the finishing strip according to the set finishing target temperature to ensure the product organization and performance of the strip. [0003] With the continuous development of metallurgical production technology, the types and specifications of strip steel have gradually expanded, and microalloy steel and carbon-manganese steel have replaced ordinary steel to become the main products. With the continuous expansion of the rolling specifications of the rolling line and the continuous improvement of the user's product quality requirements, the existing strip steel cooling device can no longer meet the needs of the production of some steel types, especially some high-strengt...
