Abstract: It is difficult to get an engineering accuracy answer of bending deflection for the section roller straightening according to elastic-plastic mechanics theory. Adequate mechanics model of section is established, combined with computer and mathmatics analysis, the relation between force and bending deflection of the section roller straightening is deduced. Compared with the traditional and engineering method, it is shown that the analytic solution accords with the production conditions and straightening theory and can give an important reference for the establishment of technological parameters.

Key words: Section  Roller straightening  Elastic-plastic  Bending deflection
