Introduction:       Nine measures to control the thickness fluctuation of special-shaped steel pipe are as follows:      ( 1) When the concentration of emulsion is increased from 2.5% to 4%, the oil film thickness of the effective contact zone between the roller and the special-shaped steel tube strip is increased, the lubrication performance is improved, and the friction coefficient is reduced, so as to reduce the rolling force and improve the thickness fluctuation.      ( 2) By adding acid additives, the pH value of emulsion is controlled at 5-5.5, the particle size of rolling oil tends to increase, the stability of emulsion is reduced, and the ESI is reduced from 60% - 80% to 40% - 60%, so as to improve the oil-water separation effect and improve the performance of profiled steel pipe
