Hardened Temper Rolling Mill Four Roller For Carbon Steel High Elasticity
Functions and applications
It consists of two series of two rollers 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 surace clearness. Four-roller leveler unit for middle and wider coils and plates is equipped with hydraulic AGC pressing down and rolling line automatic adjusting device, The work rolls adopt hydraulic anti- bending electro-liquid servo system. At the front device and rear device equipped with S roller, anti-crinkle rollers and anti-jumping rollers, which has the functions of automatic threading and easy operation. while computer on line control can realize constant extension, constant rolling force, constant roll gap, constant tension, etc.
