The continuous casting slab or the slab is used as a raw material, heated by a step heating furnace, and the high-pressure water is descaled and then enters the roughing mill. The rough rolling material is cut into the head and tail, and then enters the finishing mill to carry out computer controlled rolling. After the final rolling, it is subjected to laminar cooling (computer controlled cooling rate) and coiler winding, and finally becomes a hot rolled steel plate. Although its mechanical properties are far less than cold-worked steel sheets, it is also inferior to forged steel sheets, but it has good toughness and ductility.
1. The surface of hot rolled steel plate is smooth, has high plasticity, toughness and mechanical strength, and is resistant to corrosion by acid, alkaline gas, solution and other media. It is an alloy steel that is not easily rusted.
2. The hot rolled sheet has low hardness, easy processing and good ductility.

The use of the products is different because of the different materials used in steel:
1. Structural steel: It is used for the production of steel for general structure and steel for welded structure. It is mainly used for the production of steel structural parts, bridges, ships and vehicles.
2, weather-resistant steel: adding special elements (P, Cu, C, etc.), has good corrosion resistance and atmospheric corrosion resistance, used in the production of containers, special vehicles, also used in building structures.
3. Steel for automobile structure: High-strength steel plate with good DRAWING performance and welding performance, used for automobile frame, tire production, etc.
4. Hot-rolled special steel: Carbon steel, alloy steel and tool steel for general mechanical structure are used in the production of various mechanical parts after heat treatment.
