Method, device, medium and equipment for preventing strip steel in temper mill from being broken

The invention provides a method, device, medium and equipment for preventing strip steel in a temper mill from being broken, and the method comprises the steps that a thickness measurement value, reported by a thickness gauge, of the strip steel in the temper mill is received in real time, and rolling force applied to the strip steel by the temper mill is in positive correlation with the thickness measurement value; when the thickness gauge breaks down, calculating a thickness difference value between the thickness measurement value and a thickness set value; and if the thickness difference value exceeds a preset threshold value, the thickness set value is received to serve as a new thickness measurement value, and the rolling force applied to the strip steel by the temper mill is determined according to the new thickness measurement value. The problem that the strip steel in the temper mill is broken due to the fact that the thickness gauge breaks down is solved, stable production of the strip steel is guara
