用途及功能 Applications and function 

分两辊、四棍两大系列。适用于退火 后冷轧带钢的平整，其主要目的是提 高带钢板型精度、改善带钢表面硬 度、延伸率。使带钢具有较好的深 冲性能、较好的板型和表面光洁度。 中、宽带精密板材四辊平整机系列配 备液压AGC压下系统、轧制线自动 调整装置。工作棍采用液压弯辊电液 伺服系统、机前机后安装”S”辊、 防皱辊、防跳辊；具有自动穿带功 能、操作方便；计算机在线控制， 可实现恒延伸率、恒轧制力、恒辊缝、恒张力等平整工艺。

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 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.
