Abstract

The invention discloses a device and method for manufacturing special-shaped steel through local heating and cold roll forming, and belongs to the technical field of metal material machining. The device mainly comprises an uncoiler, a leveler, a centering device, a shearing machine and the like, and is characterized by further comprising a forming unit composed of 3 to 6 forming racks, a set of induction heaters is arranged in front of each forming rack, the edge of a workpiece is heated to 700 DEG C-1000 DEG C when the workpiece passes through the induction heaters, and then the workpiece isgradually deformed under the action of horizontal rollers and vertical rollers on all forming racks. When the device is used for producing the special-shaped steel, the equipment investment can be saved, the hot rolling burning loss is reduced, the pickling is avoided, and the economic and social benefits are obvious.

Description

technical field [0001] This technology belongs to the technical field of metal material processing, and is a device and method for producing special-shaped steel by local heating and cold bending. Background technique [0002] At present, with the in-depth development of various industrial and civil projects, simple plate, strip and pipe construction steel can no longer fully meet the requirements of various construction projects and product processing, and special-shaped steel materials with various complex sections are emerging as the times require. Typical special-shaped materials are various channel steels, I-beams and channel steels. However, in the traditional manufacturing process of these special-shaped steel products, most of them need to heat the plate as a whole and produce it by hot rolling. The problems brought about not only increase the cost, but also affect the quality of steel products, energy consumption and steel products. Rate, etc., another problem usua...
