ANALYSIS CONCERNING OPTIMUM MATE BETWEEN ROLL SPEED AND GUIDE DISC SPEED OF TWO-HIGH ROTARY PIPE MILL

The paper deals with two mathematic models concerning the two-high rotary pipe mill with relatively large toe angle and feed angle, one for roll speed, work-piece speed and disc velocity, the other for the optimum mate between roll speed and disc velocity, which can be used as theoretic basis for consideration of actual production.
