Method for controlling scratch of tension roller caused by slipping

The invention provides a method for controlling scratch of a tension roller caused by slipping, and relates to the field of acid mills. The method comprises the following steps: controlling rolling liquid parameters and improving a roller surface to improve a friction coefficient; controlling the rolling liquid parameters comprises the steps of controlling the temperature of a rolling liquid, controlling the upper concentration limit of the rolling liquid, and controlling emulsion flow; the temperature of the rolling liquid is controlled below 50 DEG C; controlling the upper concentration limit comprises the steps of controlling the upper concentration limit of a system A to be 3.0 percent, and controlling the upper concentration limit of a system L to be 0.7 percent; and controlling the emulsion flow comprises the step of controlling the emulsion flows of the acid mills of a first machine frame, a second machine frame and a third machine frame to be over 5,500 L/min. According to themethod, a cooling effect
