Hot rolled coil is made from slab (mainly continuous casting slab) as raw material, heated and then made into strip steel by rough rolling and finishing rolling units. The hot steel strip from the last finishing mill is cooled to the set temperature through laminar flow, and then rolled into steel strip coils by the coiler. The cooled steel strip coils are processed into steel plates, flat coils, and longitudinal cut steel strip products through different finishing operation lines (leveling, straightening, transverse or longitudinal cutting, inspection, weighing, packaging, and marking, etc.) according to the different needs of users.
purpose
Due to its excellent properties such as high strength, good toughness, easy processing and forming, and good weldability, hot-rolled steel plate products are widely used in manufacturing industries such as ships, automobiles, bridges, construction, machinery, and pressure vessels.
With the increasing maturity of new technologies for controlling hot-rolled dimensional accuracy, shape, surface quality, and the continuous emergence of new products, hot-rolled steel plates and strip products have been increasingly widely used and have stronger competitiveness in the market.
