Abstract: The present disclosure discloses a steel strip coiling temperature control method, a steel strip coiling temperature control device and a steel strip processing system, which relate to the technical field of steel strip production. The method comprises: seeking a corresponding speed compensation coefficient according to a target thickness of the steel strip and a target temperature parameter; seeking a corresponding speed gain coefficient from a second correspondence table according to a steel strip speed; correcting the steel strip speed based on the speed compensation coefficient and the speed gain coefficient to obtain a corrected steel strip speed; and adjusting a cooling efficiency of a laminar flow cooling apparatus according to the corrected steel strip speed. With the method, the cooling efficiency of the laminar flow cooling apparatus can be dynamically adjusted according to the steel strip speed, thereby solving the problem that that there is a great difference in coiling temperature between a tail section of the steel strip and a front section of the steel strip caused by the steel strip throwing process, and reducing the amount of cutting loss of the steel strip.
