Product Description

 

 HOT ROLLED STEEL COIL

Hot-rolled products have excellent properties such as high strength, good toughness, easy processing and good weldability, so they are widely used in manufacturing industries such as machinery, construction, machinery, boilers, and pressure vessels.

Applications:
(1) After annealing, it is processed into ordinary cold rolling;
(2) The galvanizing unit with the annealing pretreatment device processes galvanizing;
(3) A panel that basically does not require processing.

Hot-rolled coils are made of slabs as raw materials, and are made into strips by rough rolling mills and finishing mills after heating.
The hot steel strip from the last rolling mill of the finishing rolling is cooled to the set temperature by laminar flow, and is coiled into a steel coil by the coiler.
The finishing line (leveling, straightening, cross-cutting or slitting, inspection, weighing, packaging and marking, etc.) is processed into steel sheets, flat rolls and slitting steel strip products.

 

Detailed Photos

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).
