Sep 11, 2014· Customers often ask us about the differences between hot rolled steel and cold rolled steel.There are some fundamental differences between these two types of metal.The differences between hot rolled steel and cold rolled steel relates to the way these metals are processed at the mill, and not the product specification or grade.
Cold Rolled Steel Coil and Hot Rolled Steel Coil. Hot Rolling Process for Steel Coil. Hot rolling uses slabs (mainly continuous slabs) as raw materials, and after heating, strips are made from rough rolling mills and finishing mills. The hot strip from the last rolling stand of the finish rolling is cooled by laminar flow to the set temperature.

In the hot rolling mill, a cold slab is reheated in reheating furnace and then rolled into thin coils through hot rolling process. Traditional research on hot rolling mill generally takes the two processes as two separate single-objective scheduling problems, though they are closely connected and their optimization objectives are conflicting with each other.

The performance achieved in China Steel is among the best in the world and exhibits the following levels: Target Coiling Temperature (product) 97.1% of all rolled coils within +/-15°C Target Coiling Temperature ("hot ends") 97.3% of all rolled coils within +/-20°C Final temperature differential (top to bottom surface) 99.3% of all rolled ...
The slab of non-oriented electrical steel 50W800, produced by continuous casting, was hot rolled to a thickness of 2.25 mm. When the hot-rolled coil was cooled to 100℃ (at 150℃ in the steel coil center), the pickling cold rolling mill was started. The hot-rolled coils were rolled into five cold-rolling mills.
Compared with hot rolled coil, the surface of cold rolled coil is bright, the finish is high, but it will produce more internal stress, and often annealed after cold rolling. Classification: SPC SPCD SPCE (Galvanized steel coils), galvanizing is the surface treatment technology that is coated with zinc on the surface of metal, alloy or other ...
