Carbon Steel Coil (2)
11 month ago
Hot-rolled coils are made from slabs, which are heated and then rolled into strips by rough rolling mills and finishing rolling mills. The high-temperature steel strip coming out of the finishing mill is cooled to the set temperature by laminar flow and wound into a coil by a coiler. Finishing lines for steel plate, flat coil and slitting strip products (leveling, straightening, cross-cutting or slitting, inspection, weighing, packing and marking, etc.).
Hot-rolled steel products are widely used in manufacturing industries such as ships, automobiles, bridges, construction, machinery, and pressure vessels due to their excellent properties such as high strength, high toughness, easy processing, and excellent weldability. Therefore, there is a huge demand for HRC in the market.

Classification:
Common carbon plate, excellent carbon plate, low alloy plate, ship plate, bridge plate, boiler plate, container plate, etc. Rolled hard coils: Continuous rolling of hot-rolled pickled coils at room temperature. Hot rolled steel plate products include steel strip (coil) and steel plate cut from it. The steel strip (roll) can be divided into straight rolls and finishing rolls (sub-rolls, flat rolls and slitting rolls).
