Brief introduction

The hot-rolled steel coil is made of continuous casting slab or pre-rolled slab as raw material, heated by a walking heating furnace, descaled by high-pressure water, and then entered into the rough rolling mill. Computer-controlled rolling, after final rolling, laminar cooling (computer-controlled cooling rate) and coiling by a coiler become straight rolls.

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 steel, construction, machinery, boilers, and pressure vessels. 

Application range

(1) After annealing, it is processed into ordinary cold rolling; 

(2) The galvanizing unit with pre-annealing treatment device processes galvanizing; 

(3) Panels that basically do not need to be processed.

Classification 

Common carbon plate, excellent carbon plate, low alloy plate, ship plate, bridge plate, boiler plate, container plate, etc. Hard-rolled coils: Continuously rolling hot-rolled pickled coils at room temperature. Hot continuous rolled steel sheet products include steel strips (coils) and steel sheets cut from them. The steel strip (roll) can be divided into straight hair rolls and finishing rolls (split rolls, flat rolls and slit rolls).

Hot-rolled coils (in the form of flat plates or coils) generally have a thickness of 2.0-13.5mm, of which the price of 2.0-3.0mm hot coils gradually decreases from thin to thick; most steel mills have a basic price of 3.1mm-13.5mm Equivalent, the price of 3.1-4.0mm and 9.5mm-13.5mm hot plate coils in some manufacturers and markets may be higher than the price of 4.0mm-9.5mm plates. Hot plate coils represent products with a thickness of 5.5mm. Under normal circumstances, the price of flat plates is slightly higher than the price of coils.
