LW400-6 cold bending steel welded pipe production line, the production line to meet opening cold bend steel, square rectangle tube production process requirements.In hot rolled strip steel as raw material, through the method of cold bending forming and high frequency welding production required specifications of the opening cold bend steel, square,rectangle pipe and round pipe.Reproduction of a complete set of unit when opening cold bend steel rectangular pipe and adopts the most advanced international level of multipoint to combined bending, pipe when using popular titles include FFX forming technology in production.These two forming modes of deformation process make a force more reasonable, the unit of each frame material deformation by the original line contact into point contact.Two forming modes are used the world's advanced technology and the organic combination of both ,as also the cold bending steel and welding pipe technology product requirement.
Full unit set of significant features:
(1). square rectangle pipe and opening cold bend steel using a multipoint to bending roll, the round pipe in rough shape closed before using a set of popular titles include FFX forming roll ,the roll above the set without replacement, reduce the roll cost more than 90%.
(2). the unit each frame of the deformation of material section by a line contact into contacts the whole unit to reduce energy consumption by over 30%.Save the strip width 2.3 ~ 2.5%. |
