用途及功能 Applications and function 

分兩輥、四棍兩大系列。適用于退火 后冷軋帶鋼的平整，其主要目的是提 高帶鋼板型精度、改善帶鋼表面硬 度、延伸率。使帶鋼具有較好的深 沖性能、較好的板型和表面光潔度。 中、寬帶精密板材四輥平整機系列配 備液壓AGC壓下系統、軋制線自動 調整裝置。工作棍采用液壓彎輥電液 伺服系統、機前機后安裝”S”輥、 防皺輥、防跳輥；具有自動穿帶功 能、操作方便；計算機在線控制， 可實現恒延伸率、恒軋制力、恒輥縫、恒張力等平整工藝。

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.
