Power part is composed of leveling base, speed reducer, YWZ arrester, coupling, power distribute box, joint spindle joint sleeve, universal drive shaft and so on. Main motor equip with high power direct current adjust motor and high capability direct current adjustment. With more high starting pitch of strand than rating, less voice and good reliability.

Main motor is separated up and down two rolls each part. composed of machine base, double housing type frame, up/down bearing base, beam, roll support ,roll support frame , roll support base , worm wheel and worm pole drive to control the upper roll come up and down. Two speed reducers adjust the distance of up and down in entrance and exit rolls. Simile adjustment manually. display on the percent gauge. Leveling working roll 6CrWMoV material , support roll material is 40Cr. Its forming procures is modulator and intermediate frequency quench and surface plating Cr precise grand, no mark on the surface of sensitivity material .the hardness of leveling working roll is HRC55-58, the hardness of support roll is HRC48-53. We adopt needle roller bearing and plane bearing support leveling roller so as to reduce the resistance of whole
