Title:
STRIP STEEL COILING TEMPERATURE CONTROL METHOD AND APPARATUS AND STRIP STEEL MACHINING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/017262
Kind Code:
A1
Abstract:
A strip steel coiling temperature control method. The method comprises: searching for a corresponding speed compensation coefficient in a first corresponding table according to a strip steel target thickness and target temperature parameters; searching for a corresponding speed gain coefficient in a second corresponding table according to a strip steel rolling speed; correcting the strip steel rolling speed on the basis of the speed compensation coefficient and the speed gain coefficient to obtain the corrected strip steel speed; and adjusting the cooling efficiency of a laminar cooling device according to the corrected strip steel speed. Also provided are a strip steel coiling temperature control apparatus and a strip steel machining system. According to the method, dynamic regulation of the cooling efficiency of the laminar cooling device can be achieved according to the strip steel rolling speed, thereby avoiding the problem that the difference between a strip steel tail portion coiling temperature and a front section coiling temperature is too large due to steel throwing, and decreasing the cutting loss of the strip steel.
