1. Production process of hot rolled steel plate:
Using slabs or blooming slabs as raw materials, heated by a walking heating furnace, high-pressure water descaling, then enters the rough rolling mill, the rough rolling material is cut head and tail, and then enters the finishing rolling mill, where computer-controlled rolling is implemented, and after finishing rolling That is, after laminar cooling (computer-controlled cooling rate) and coiling machine, it becomes a straight hair roll. The head and tail of straight hair curlers are often tongue-shaped and fish-tail-shaped, with poor thickness and width accuracy, and the edges often have defects such as wave shape, hemming, and tower shape. The coil weight is heavier, and the inner diameter of the steel coil is 760mm.
After the straight hair coil is processed by a finishing line such as head cutting, tail trimming, edge trimming and multi-pass straightening and leveling, then the plate is cut to become: hot-rolled steel plate, flattened hot-rolled steel coil, slitting strip, etc. product.
2. Application of hot rolled steel plate:
1. Structural steel
2. Weather resistant steel
3. Steel for automobile structure
4. Hot rolled special steel
5. Cold rolled original plate
6. Steel plate for steel pipe
7. Steel plate for high pressure vessel
8. Stainless steel plate
