| 摘 要： | H型钢辊式矫直机在辊压腹板时使翼缘产生塑性变形以达到矫直目的.为了避免矫直过程中出现矫直缺陷,通过建立适当的矫直力学模型,求出了H型钢九辊矫直的压弯挠度与弯矩、矫直力的解析关系,确定了生产中调节矫直辊压弯挠度来保证各辊处的弯矩、矫直力等力能参数的范围.

| Abstract: | Aiming at H-beam straightening, the plastical deformation of H-beam flange should be ocurred when the rollers pressed the web plate. In order to avoid flaws in the process of H-beam straightening, an adequate mechanical model was established and the relations between bending moments, forces and bending deflections of the H-beam in nine-roller straightening were deduced. The range of the technological parameters such as forces and bending moments under each straightening roller was determined by adjusting the bending deflections in practice. |
