摘要
Abstract
In order to improve the JCO forming welded pipe quality and enhance steel pipe production efficiency, based on a JCO forming unit forming technology, in view of the problems appeared in forming process, according to the practical experience to make a detail research and adjustment measures for adjustment measures. The research results indicated that the radius-thickness ratio of steel pipe, the yield strength of steel plate and forming reduction will affect steel pipe ovality. In forming process the compensation of upper and lower beam will impact on steel pipe straightness;improper compensation and inaccuracy pusher location can cause steel pipe helicity; the size of pre-bending rate is the key factor of affecting steel pipe pouting quantity and steel pipe shape. Finally, it put forward the specific adjustment measures based on research results.关键词
