Characteristics and uses of hot rolled steel coils

Hot-rolled coils are made from slabs (mainly continuous casting slabs). The hot steel strip coming out of the final rolling mill of finishing rolling is cooled to a set temperature by laminar flow, and then coiled into a steel strip coil by a coiler. The cooled steel coil is subjected to different finishing procedures according to the different needs of users. Production lines (leveling, straightening, cross-cutting or slitting, inspection, weighing, packaging and marking, etc.) into sheet, flat coil and slitted strip products. Hot continuous rolled steel plate products are widely used in shipbuilding, automobile, bridge, construction, machinery, pressure vessel and other manufacturing industries due to their excellent properties such as high strength, good toughness, easy processing and good weldability. Hot continuous rolling can be divided into ordinary carbon structural steel, low alloy steel and alloy steel according to material and performance.

According to different uses, it can be divided into: cold-formed steel, structural steel, automobile structural steel, corrosion-resistant structural steel, mechanical structural steel, welded gas cylinder and pressure vessel steel, pipeline steel, etc.
Hot continuous rolled steel plate products have a wide variety of steel grades and specifications, and are widely used. They are used in the manufacture of everything from general engineering structures to automobiles, bridges, ships, boilers and pressure vessels. Different uses have different requirements on the material properties, surface quality, size and shape accuracy of steel plates. Therefore, it is necessary to understand the varieties, materials, characteristics and uses of hot-rolled steel plates in order to achieve economic benefits.
