The hot-rolled carbon steel coil is made of a continuous casting slab or pre-rolled slab as raw material, heated by a walking heating furnace, descaled by high-pressure water, and then entered into the rough rolling mill. Computer-controlled rolling, after final rolling, laminar cooling (computer-controlled cooling rate), and coiling by a coiler become straight rolls. Hot-rolled products have excellent properties such as high strength, good toughness, easy processing, and good weldability, so they are widely used in manufacturing industries such as steel, construction, machinery, boilers, and pressure vessels.
Application range:
(1) After annealing, it is processed into ordinary cold rolling;
(2) The galvanizing unit with pre-annealing treatment device processes galvanizing;
(3) Panels that do not need to be processed.
