Hot rolled coil is made of continuous casting slab or priming slab as raw material, heated by step heating furnace, high pressure water descaling into roughing mill, roughing mill through cutting, tail, and then into finishing mill, implementing computer-controlled rolling, after the final rolling laminar cooling (computer-controlled cooling rate) and coiler winding, straight coil.

Hot rolled coils are suitable for applications where perfect surfaces and precise dimensions are not required. But they have some excellent properties, such as high strength, high toughness, good weldability. Therefore, hot-rolled products are widely used in construction, automotive structures, machinery, boilers, pressure vessels, steel pipes and other manufacturing industries, including:

Construction: Building structures, frames, Bridges, fences, partitions, rails, I-beams, etc.

Pipelines are used for the transport of oil, gas, water, heating networks and sewage pipelines;

Machinery products, body and components machinery, cars and trucks, tanks, cranes, etc

Hot rolled steel is rolled at a very high temperature, which is higher than the recrystallization temperature of the steel. Here’s a look back at how it was made.

1.the billet into the heating furnace;

2. the use of hydraulic descaling machine to remove the surface scale;

3.Feed the roughing mill and cut the end;

4.after finishing mill to adjust the thickness and width of the coil to form a smooth surface;

Let cool and roll into rolls.
