Hot rolled steel plate
| Item | Hot rolled steel plate/ sheet |
| Introduction | Using continuous casting slab or blooming slab as raw material, it is heated by a walking heating furnace, high-pressure water is descaled and then enters the rough rolling mill. The rough rolling material is cut head, tail, and then enters the finishing rolling mill for computer-controlled rolling. After the final rolling, it undergoes laminar cooling (computer-controlled cooling rate) and coiled by a coiler to become a straight hair coil. 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-cutting, edge-trimming, and multi-pass straightening and leveling, then it is cut or re-coiled to become: hot-rolled steel plate, flattened hot-rolled steel coil, longitudinal Cut tape and other products. If the hot-rolled finished coil is pickled to remove the oxide scale and coated with oil, it will become a hot-rolled pickled coil. This product has a tendency to partially replace cold-rolled sheet, and the price is moderate, and it is deeply loved by the majority of users. Good ductility, cold-rolled sheet has high hardness and relatively difficult processing, but it is not easy to deform and has high strength. The strength of the hot-rolled plate is relatively low, and the surface quality is poor (oxidation\low finish), but the plasticity is good, generally medium and thick plates, cold-rolled plates: high strength\high hardness, high surface finish, generally thin plates, can be used as stamping Used board. Hot-rolled steel plate has mechanical properties far inferior to cold working and inferior to forging processing, but it has better toughness and ductility. |
