After the straight coils are processed by head cutting, tail cutting, edge trimming and multi-pass straightening, leveling and other finishing lines, they are then cut into plates or re-rolled to become: hot-rolled steel plates, flat hot-rolled steel coils, longitudinal steel coils, etc. Cutting tape and other products. If the hot-rolled finished rolls are pickled to remove scale and oiled, they become hot-rolled pickled rolls. This product has the tendency to partially replace cold-rolled plates, is moderately priced, and is very popular among users.
Hot-rolled plates have relatively low strength and poor surface quality (oxidation and low smoothness), but have good plasticity and are generally medium-thick plates.
Type use:
1. Structural steel: mainly used in the production of steel structural parts, bridges, ships, and vehicles.
2. Weathering-resistant steel: Added with special elements (P, Cu, C, etc.), it has good corrosion resistance and atmospheric corrosion resistance. It is used in the production of containers, special vehicles, and building structures.
3. Steel for automobile structures: high-strength steel plates with good stamping performance and welding performance, used in the production of automobile frames, wheels, etc.
4. Hot-rolled special steel: Carbon steel, alloy steel, and tool steel are used for general mechanical structures. They are used in the production of various mechanical parts after heat treatment.
5. Cold-rolled raw plates: used to produce various cold-rolled products, including CR, GI, color-coated plates, etc.
6. Steel plate for steel pipe: It has good processing performance and compressive strength and is used to produce high-pressure gas pressure vessels with a content volume of less than 500L and filled with LPG, acetylene gas and various gases.
7. Steel plate for high-pressure vessels: It has good processing performance and pressure resistance, and is used to produce high-pressure gas pressure vessels with a content volume of less than 500L and filled with LPG, acetylene gas and various gases.
8. Stainless steel plate: Stainless steel has good corrosion resistance and is mainly used in the food industry, surgical equipment, aerospace, petroleum, chemical industry and other industries.
