Flat bar production process
Precision flat bar flat bar production process of pure machine working principle is to cold flat bar wool bad leveling wheel with two groups of staggered up and down the thickness direction for pre school and eventually leveling. With a pair of relative to its width to finishing wheel extrusion, make width is compressed and achieve the desired parameters, the compression quantity adjustable. With five interlaced arrangement of straightening roller straightening on its width. This system is mainly composed of control box, finishing roller, leveling unit, finishing unit, straightening units. Its production process can be summarized as: preliminary leveling - after finishing to alignment leveling. Flat bar is with12-300 mm wide and 4-60 mm thick with cross section of rectangle and slightly with the edge of the pure steel. Flat bar can be finished steel, also can be welded pipe billet and pack rolling sheet with thin slab. Main usage of the flat bar is as timber can be used in the system of hoop iron parts, tools and machinery, building used as frame structure, escalator. Flat bar according to its shape can be divided into two kinds: flat spring flat bar and single double groove spring flat bar. Hot spring flat bar is mainly used in the manufacture of automobiles, tractors, leaf spring on the railway transportation machinery.
