Hot rolled coil is made of continuous casting slab or initial rolling slab as raw material, heated by a stepper heating furnace, descaling by high-pressure water, and then enters the roughing mill. The roughing material is cut into heads, tails, and then enters the finishing mill for computer-controlled rolling. After final rolling, it is cooled by laminar flow (computer-controlled cooling rate) and coiled by a coiler to become straight coil.
Can be used to manufacture many common steel products, such as automotive parts, building materials, and pipelines. This production process can produce steel plates with high strength, high quality, precise shape and size to meet the needs of various industrial and consumer markets.
Hot rolled products have excellent properties such as high strength, good toughness, easy processing and good weldability, and are therefore widely used in manufacturing industries such as construction, machinery, boilers, and pressure vessels.
In the production process of hot-rolled coils, it is first necessary to load the cooled steel billet into the heating furnace and use high temperature and pressure to hot-roll it into thin coils. The rolls are then fed into cooling equipment for rapid cooling and solidification. This process increases the strength and durability of the steel and enables the control of the size and shape of the steel, thereby improving production efficiency and quality.
Next, the coil goes through a series of processing steps, including surface cleaning, cutting, and coiling, in order to turn it into the final product. During these steps, production workers use various advanced equipment and tools to ensure that each coil meets strict quality standards and specifications.
