Intelligent 1+4 hot continuous rolling tank body material tail control method

The invention discloses an intelligent 1+4 hot continuous rolling tank body material tail control method. The control method comprises the following steps that 1), a 3104 tank body material is conveyed to an inlet of a finish rolling set, and a finish rolling model is used to calculate a set value of bending roller force required by each machine frame of finish rolling based on temperature, thickness and width of the 3104 tank body material, and actual shape of a roller; 2) after each machine frame of finish rolling bites the 3104 tank body material, the bending roller force of each machine frame is switched from balance force to the bending roller set value calculated by the finish rolling model; 3) in the rolling process of the finish rolling set, the temperature of a tail strip materialis detected; and 4) control over the bending roller and a roller gap by a WRB bending roller control system and an AGC roller gap control system in the rolling process of the finish rolling set is cut off according to the de
