Hot rolled steel coils , it uses slab (mainly continuous casting billet) as raw material, and after heating, it is made into strip steel by rough rolling mill and finishing mill.
Hot rolled steel coils have many advantages. First of all, it has higher strength and hardness, which can withstand greater load and pressure. Secondly,Jiacheng steel coil due to the heat treatment, an oxide skin layer is formed on the surface, which can effectively prevent corrosion and rust. In addition, due to the advantages of high production efficiency and low cost, hot rolled steel coil has become the main material in many industries.

In addition, due to the advantages of high production efficiency and low cost, hot rolled steel coil has become the main material in many industries.
The hot steel strip from the last rolling mill of the finishing rolling is cooled to a set temperature by laminar flow, and then coiled into a steel coil by the coiler. The cooled steel coil undergoes different finishing operations according to the different needs of users. Lines (flattening, straightening, cross-cutting or slitting, inspection, weighing, packaging and marking, etc.) are processed into steel plates, flat coils and slit steel strip products.
Product category
Hot rolls can be divided into straight hair rolls and finishing rolls (divided rolls, flat rolls and slit rolls).
According to its material and performance, it can be divided into: ordinary carbon structural steel, low alloy steel, alloy steel.
