Hot Roll Steel Coil

Hot roll steel coil is made of slab (mainly continuous casting slab) as raw material, which is heated and then made into strip steel by roughing mill and finishing mill. The hot-rolled strip of the last finishing mill is cooled to a set temperature by laminar flow, and then rolled into a strip...

Product details

Name

---- hot roll steel coil

Standard

---- AISI, ASTM, BS, DIN, GB, JIS

Advantages

----1) Hot rolling can significantly reduce energy consumption and cost. In the hot rolling process, the metal has high plasticity and low deformation resistance, which greatly reduces the energy consumption of metal deformation.

----2) Hot rolling can improve the processability of metals and alloys. Coarse grains in the cast state will break, obvious cracks will heal, reduce or eliminate casting defects, transform the cast structure into deformed structure, and improve the processability of the alloy.

----3) Hot rolling usually adopts large ingot rolling with large reduction, which not only improves the production efficiency, but also creates conditions for increasing the rolling speed and realizes the continuity and automation of the rolling process.
