Strip steel winding temperature control method and device and strip steel machining system

Abstract

The invention discloses a strip steel winding temperature control method and device and a strip steel machining system, and relates to the technical field of strip steel production. The method comprises the steps that a corresponding speed compensation factor is looked up according to the target thickness and target temperature parameters of strip steel; a corresponding speed gain coefficient is found from a second corresponding table according to the strip steel rolling speed; the strip steel rolling speed is corrected based on the speed compensation factor and the speed gain coefficient, andthe corrected strip steel speed is obtained; and according to the corrected strip steel speed, the cooling efficiency of laminar cooling equipment is adjusted. Through the method, dynamic regulationof the cooling efficiency of the laminar cooling equipment can be achieved according to the strip steel rolling speed, accordingly, the situation that the difference between the tail winding temperature and the front section winding temperature of the strip steel is too large due to steel throwing is avoided, and the cutting loss of the strip steel is decreased.

Description

technical field [0001] The application relates to the technical field of strip steel production, in particular, to a strip steel coiling temperature control method, device and strip steel processing system. Background technique [0002] In the hot continuous rolling production line, it is a difficult problem to control the coiling temperature to ensure the uniform coiling temperature of the strip throughout the length, especially for the thin strip steel, because the speed of the strip steel will change rapidly during the strip throwing process, resulting in the The speed of the tail passing through the cooling zone has a certain deviation compared with the front section of the strip, which leads to the problem that there is a difference between the coiling temperature of the tail of the strip and the coiling temperature of the front section. [0003] In the prior art, the cooling efficiency of the cooling equipment is usually adjusted according to the thickness of the strip...
