Hot-rolled steel/coil from finishing the last hot steel strip mill out through laminar flow cooling to the set temperature, which consists of the winder coil, steel coil after cooling, according to the different needs of users, with different finishing line (flat, straightening, transverse or longitudinal cutting, inspection, weighing, packaging and logo, etc.) and become a steel plate, flat roll and longitudinal cutting steel strip products. Because hot rolled steel products have high strength, good toughness, easy processing and good weldability and other excellent properties, it is widely used in shipbuilding, automobile, bridge, construction, machinery, pressure vessel and other manufacturing industries.

热轧钢板/卷板从精加工后的热轧带钢经层流冷却至设定温度，其中由卷板、卷板组成，卷板经冷却后，可根据用户的不同需要，采用不同的精加工线(平、校直、横向或纵向切割、检验、称重、包装及标识等)而成为钢板、平卷和纵向切割的带钢产品。由于热轧钢产品具有强度高、韧性好、易加工和可焊性好等优异性能，被广泛应用
