The hot rolled coil is made of slab (mainly continuous casting billet), and is heated to be made of strip by rough rolling mill and finishing mill. The hot steel strip from the last rolling mill of the finishing mill is cooled to a set temperature by laminar flow, and is rolled into a steel coil by a coiler, and the cooled steel coil is rolled. According to the different needs of users, through different finishing lines (flat, straightening, cross-cutting or slitting, inspection, weighing, packaging and marking), it becomes a steel plate, flat roll and slitting steel strip. Since hot-rolled steel sheet products have high strength, good toughness, easy processing and good weldability, they are widely used in shipbuilding, automobiles, bridges, construction, machinery, pressure vessels and other manufacturing industries.
With the increasing maturity of new technologies such as hot-rolling dimensional accuracy, plate shape and surface quality, and the advent of new products, hot-rolled steel sheets and strip products have become more and more widely used and are becoming more and more powerful in the market. Competitiveness.
Main products
Hot rolling can be divided into ordinary carbon structural steel, low alloy steel and alloy steel according to its material and performance.
According to their different uses, they can be divided into: cold forming steel, structural steel, automobile structural steel, corrosion resistant structural steel, mechanical structural steel, welding gas cylinder, pressure vessel steel, pipeline steel, etc.
General description
Hot-rolled steel products, steel types and specifications, a wide range of applications, from general engineering structures to automobiles, bridges, ships, boilers and pressure vessels, etc., are widely used. For various purposes, the requirements for the material properties, surface quality, size and shape accuracy of the steel sheet are also different. Therefore, it is necessary to understand the varieties, materials, characteristics and uses of the hot-rolled steel sheet products in order to achieve economical efficiency. Reasonable use.
