Process performance of hot rolled coil

RELEASE TIME :

2023-07-11 13:27

Hot rolling is a relatively simple product in steel, which can be produced by basically domestic steel mills. It is used for ordinary stamping, bending, and stretching, and can be stored for a long time. It is also called ordinary carbon steel.

The slab (mainly continuous casting slab) is used as the raw material, and the strip steel is made by the rough rolling unit and the finishing rolling unit after heating. The hot steel strip coming out of the last rolling mill of finishing rolling is cooled to the set temperature by laminar flow, and rolled into steel strip coils by the coiler. The cooled steel strip coils undergo different finishing operations according to different needs of users. Wire (leveling, straightening, cross-cutting or slitting, inspection, weighing, packaging and marking, etc.) processed into steel plate, flat coil and slitting steel strip products, its strength is not very high, but plasticity, weldability It is better, the appearance color is not bright, and it is easy to corrode. Because the price is relatively cheap, most companies use it to reduce costs, so they are more commonly used. The steel is hot-pressed and cold-pressed into rolls. In order to facilitate storage and transportation, it is convenient for various processing (such as processing into steel plates, steel strips, etc.)
