Hot Rolled Coil Black

Hot rolled coils are steel coils produced through the hot rolling process and are widely used in multiple industries. Here are the key points:

1. Definition
Hot rolled coil: Rolling steel billets into thin plates or coils at high temperatures, usually above the recrystallization temperature.

2. Production process
Heating: Heat the steel billet to 1100 ° C to 1300 ° C.

Rolling: Achieving the desired thickness through multiple passes of rolling.

Cooling: Natural cooling or controlled cooling after rolling.

Roll up: After cooling, roll up into a coil.

 Hot rolled steel coil including common steel, high quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel and industrial pure iron sheet.

 According to professional use, there are oil barrel board, enamel board, bulletproof board and so on.

application 

Buildings: steel structures, bridges, ships, etc.

Automobile: body frame, chassis parts, etc.

Mechanical manufacturing: equipment casings, components, etc.

Pipeline: Oil and natural gas transmission pipeline.

    Due to the high strength, good toughness, easy processing, and good weldability of hot rolled steel products, they are widely used in manufacturing industries such as ships, automobiles, bridges, construction, machinery, and pressure vessels.
