Mar 25, 2021 · Because the cold-rolled original coil is relatively brittle and hard, it is not suitable for processing. Generally, cold-rolled steel sheets require annealing, pickling, and surface smoothing before being handed over to the customer. The maximum thickness of cold rolling is below 0.1-8.0MM.
Hot Rolled Steel vs. Cold Rolled Steel (Ultimate Hot rolling is the rolling process beyond crystallization temperature while cold rolling is the rolling process under the crystallization temperature. The change of cold rolled steel shape is a continuous cold deformation, and the cold hardening of this process causes the strength, hardness, and toughness of hard rolled coil to decrease.

RollingHistoryHot and Cold RollingProcessesMillsDefectsHOT ROLLING Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usuallSHAPE ROLLING DESIGN Rolling mills are often divided into roughing, intermediate and finishing rolling cages. During shape rolling, an initial billet (round or square) with edge of diameter typically ranging between 100140 mm is continuously deformed to produce a certain finished product with smaller cross section dimension and COLD ROLLING Cold rolling occurs with the metal below its recrystallization temperature (usually at room temperature), which increases the strength via strain hardening up to 20%. It also improves the surface finish and holds tighter tolerances. Commonly cold-rolled products include sheets, strips, bars, and rods; these productCold Rolled Coils - Cold Rolled Full Annealed Sheets Cold reducing coils of hot-rolled pickled steel, then annealing (heat treating to high temperatures) make the sheet thinner and leads to a refinement of the steel and gives the steel very desirable and unique forming properties.
Galvanized Cold Rolled Full hard coils are annealed and coated with varying level of zinc coating to prevent rust and provide either a smooth or bright and shiny finish Galvannealed Similar to galvanized in its rust prevention properties, cold rolled full hard is annealed in order to form galvanneal that has a harder surface that
