A roller leveler main design
Abstract: rolling of the rolling, cooling and transport process, due to the influence of various factors tend to produce the shape defect. Some cross-section of the beam (I-beam, etc.) will produce flanges and external expansion and reverse. Sheet and strip (wavy) will produce vertical bending, lateral bending, and the edge of the wave-shaped and intermediate buckling and camber. In order to eliminate these defects, rolling on the straightening machine to be corrected. Finally straightening process in the straightening machine, a plurality of straightening rolls profiles several repeated bending, so that originally has a variety of curvature of the profile of a single straightening curvature in the same direction, and then the last bending the purpose of straightening. In this paper, a simple roller leveler research and discussion describes the design process and the design elements of the two-roll Straightened straightening bars. The second roller is convex roller, a concave roller the guide plate is formed by a straightening bar straightening channel. Through the roller-shaped curve with straightening function.

1矫直设备概述
矫直技术产生的确切时间尚未找到准确的文字记载。但从文物发掘中看到我国春秋战国时期包间的平直度可以使人想象到当时手工矫直和平整技术已经达到了很高水平。20世纪50年代苏联的矫直机大量进入到中国。同时世界上随着电子技术及计算机技术的发展，工业进步速度加快，矫直机的品种、规格、结构、及控制系统都得到不断的发展与完善。
近年来我国在反弯辊型七斜辊矫直机，多斜辊薄壁管矫直机、3斜辊薄壁管矫直机、双向反弯辊型二辊矫直机、复合转毂矫直机，平行辊异辊距矫直机等研制方面相继取得成功。在矫直高强度合金钢方面也已获得很好的矫直质量。此外，从20世纪60年代以后拉伸与拉弯矫直设备得到很大发展，对带材生产起到重要作用。主要类型有压力矫直机、拉伸矫直机、辊式矫直机等等。
1.1 压力矫直机
压力矫直机的工作原理是使工件在活动压头和两个固定支点间，利用反弯的方法进行矫直。压力矫直机分立式和卧式两种。这种矫直机用来矫直大型钢梁、钢轨和大直径(大于Φ200~300毫米)钢管或用作辊式矫直机的补充矫直。压力矫直机的主要缺点是生产率低且操作较繁重。
