Hot rolled coils use slabs (mainly continuous cast slabs) as materials, and after heating, strips are assembled by rough rolling units and finishing rolling units.
Hot-rolled coils are cooled by laminar flow to the set temperature from the final rolling mill. The coils are rolled into coils. After cooling, the coils are cooled according to the different needs of the user. The finishing line (crushing, straightening, cross-cutting or slitting, inspection, weighing, packaging and marking, etc.) is processed into steel plates, slender coils and slitting strip products.
Because hot-rolled steel products have high strength, good resistance, easy processing, and excellent weldability, they are widely used in vessels, automobiles, railways, construction, machinery, pressure vessels, etc.
Occupation. Along with the increasingly sophisticated new technologies for correcting hot-rolled scale accuracy, shape, surface quality and new products, hot-rolled steel plates and strip products have been used more and more widely and have become more and more powerful in the market. Competitiveness.
What is hot rolled coil? What are the types of hot rolled coil?
Hot-rolled steel sheet products include steel strips (rolls) and steel sheets cut from them. Steel strips (rolls) can be divided into straight hair rolls and finishing rolls (divided rolls, flat rolls and slit rolls).
Hot continuous rolling can be divided into: general carbon structural steel, low alloy steel, and alloy steel according to their raw materials and functions.
It can be divided into: cold forming steel, structural steel, passenger car structural steel, corrosion resistant structural steel, mechanical structural steel, welded gas cylinders, container steel that can accept pressure, and steel for pipelines.
