在型钢轧制的企业，一般是通过矫直机来完成矫直的。 角钢，槽钢，工字钢，h型钢，轻轨，重轨，翼缘板，u型钢的矫直方法。

       主要类型有压力矫直机、平行滚矫直机、斜滚矫直机、旋转反弯矫直机、拉伸与拉弯矫直机等等。

       矫直与弯曲是俩个相反的工艺过程，但它们的变形机理是相同的。为了将钢材矫直，首先要了解金属的弹性特征;通常;不同金属的弹性很 限大小有所不同。就是说在塑性变形时也伴随这弹性变形。过去在矫直生产中，人们就认识到弹性的存在，也总结出了"矫枉过正"的规律，也是矫直操作的基本原理。

       In the steel rolling enterprises, generally through the straightening machine to complete the straightening. Angle steel, channel steel, I beam, h beam, light rail, heavy rail, flange plate, u beam straightening method.

       The main types are pressure straightener, parallel roll straightener, oblique roll straightener, rotary reverse bending straightener, stretch and stretch bending straightener and so on.

       Straightening and bending are two opposite processes, but their deformation mechanism is the same. In order to straighten the steel, it is necessary to understand the elastic characteristics of the metal; Usually; Different metals have different elastic limits. That is to say, plastic deformation is accompanied by elastic deformation. In the past, people realized the existence of elasticity in straightening production, and summed up the law of "overcorrection", which is also the basic principle of straightening operation.
