(skin pass mill,skin pass machine,temper machine) It consists of two series of tworollers and four rollers. It is used for leveling the annealed cold rolling strips in order to improve the machinery functions to enhance the surface hardness, strength and elasticity of CR strips. Meanwhile, the CR strips through the leveler unit can have functions of excellent deep punching, shapes and surface clearness. Four rollers leveler unit for middle and wider coils and plates is equipped with hydraulic AGC pressing down and automatic adjusting rolling elevation lever installations. The working rollers adopt hydraulic reverse bending electro-liquid servo system. Roller "S", anti-crinkle rollers, and anti-jumping rollers are set up to the front and rear machines with functions of strips transmission automatically and easy operation. Leveling technics such as constant extension, constant rolling force, constant clearance of rollers, and constant tension can come true by computer online control.
