Cold rolling forming equipment and method for preparing channel by using carbon steel or stainless steel

The invention discloses cold rolling forming equipment and method for preparing a channel by using carbon steel or stainless steel, and belong to the technical field of metal material preparation. Theequipment is characterized by being mainly composed of a primary rolling unit including 3-4 cold rolling machines, a bright annealing furnace kiln, a gear pressing unit, a finish rolling unit including 2-3 cold rolling machines, a pre-forming and final-forming unit, induction heaters and a computer control device, the induction heaters are positioned in front of the units, and a channel finishedproduct with a main vertical surface thickness of 6.0-12.0mm and a width of 40-200mm can be manufactured through cold rolling forming and continuous operation by using the equipment. Compared with a common hot rolling forming technology, the surface of the finished product is not damaged, the hardness of the finished product is 1.6 times that of a hot rolled product, and the production efficiencycan be improved by 30% due
