Classification and application of hot coil;
Hot coil can be divided into straight coil and fine coil, flat coil and longitudinal coil. According to the different materials and properties, it can be divided into ordinary carbon structural steel, low alloy steel and alloy steel. According to different uses, it can be divided into cold-formed steel, structural steel, automobile structural steel, corrosion-resistant structural steel, mechanical structural steel, welding steel for gas cylinders and pressure vessels, pipeline steel and so on.
Hot rolled steel plate products have excellent properties such as high strength, good toughness, easy processing and forming, and good weldability, and are widely used in shipbuilding, automobiles, bridges, construction, machinery, pressure vessels and other manufacturing industries. The hot steel strip from the last finishing mill is cooled to the set temperature by laminar flow, and is coiled into a steel strip coil by a coiler, and the cooled steel strip coil.
With the maturity of new control technologies such as dimensional accuracy, shape and surface quality of hot rolling and the emergence of new products, hot rolled steel plates and strips have been widely used and become more and more competitive in the market.
