Hot rolled coil, also known as hot-rolled coil, is made from slab (mainly continuous casting slab) as raw material, heated and then processed into strip steel by roughing and finishing mills. The hot steel strip coming out of the last finishing mill is cooled by laminar flow to the set temperature, and then rolled into steel strip coils by the coiling machine. The cooled steel strip coils. The sheet metal that has undergone hot rolling treatment and has not yet been flattened by the flattening machine is called hot rolled sheet metal.

Product classification
Hot coils can be divided into straight coil and finishing coil (divided coil, flat coil, and longitudinal cut coil). According to their different materials and properties, they can be divided into ordinary carbon structural steel, low alloy steel, and alloy steel.
According to their different uses, they can be divided into:cold formed steel, structural steel, automotive structural steel, corrosion-resistant structural steel, mechanical structural steel, welded gas cylinder and pressure vessel steel, pipeline steel, etc.
purpose
Due to its 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, pressure vessels, household appliances, hardware, furniture, etc.
With the increasing maturity of new control technologies such as hot-rolled dimensional accuracy, plate shape, and surface quality, as well as the continuous emergence of new products, products such as hot-rolled steel plates have been widely used and have stronger competitiveness in the market.
