TISCO/POSCO/BAOSTEEL cold roll 201 430 304 stainless steel coil
Hot rolling coil uses continuous casting slab or blooming slab as raw material, which is heated by stepping heating furnace and descaled by high-pressure water, and then enters the roughing mill. The roughing material enters the finishing mill after cutting head, tail and then enters the finishing mill for computer-controlled rolling. After final rolling, it is rolled into straight hair coil through laminar cooling (computer-controlled cooling rate) and coiler.

Benefits of Hot Rolled Steel
Hot rolled steel offers several manufacturing advantages, such as:
-
Lower cost: Hot rolled steel tends to be less expensive than cold rolled steel since it involves less processing.
-
Better workability: As the hot rolling process occurs at elevated temperatures, the processed material is easy to form and shape.
-
Little to no internal stress: The hot rolling process involves cooling the steel gradually, which allows the material to essentially normalize its structure and become free of internal stresses.
Surface finish :
| Surface Finish | Definition | Application |
| 2B | Finished by heat treatment, pickling after cold rolling. Followed by skin pass line to be more brighter and smooth surface | General application Medical instruments, Tableware |
| BA | Bright heat treament after cold rolling | Kitchen utensil, kitchenware, architectural |
| 8K | A mirror-like reflective surface by polishing with finer abrasives over 800mesh | Construction, mirrors, plate sets, decoration elevators |
| HL | Finished by continuous linear polishing | Architectural purpose, Escalators, kitchenware, vehicles |
| NO.1 | Finished by hot rolling, annealing and picking, characterized by white pickled surface | Chemical industry Equipment, industrail tanks |
| NO.4 | Polishing with NO.150 to NO.180 mesh abrasives specified in JISR6001 | Kitchen utensils, Building Construction, Medical equipment |
Applications of Hot Rolled Steel
Since hot rolled steel shrinks slightly during the cooling stage, there is a lesser degree of control over its final shape. For this reason, it is typically used in applications that do not require extremely tight tolerances, such as:
-
Agricultural equipment
-
Automobile parts (e.g., frames and wheel rims)
-
Construction materials (e.g., I-beams)
-
Railroad equipment (e.g., tracks and railcar components)
