The concept is similar to the rolling of dough rolling is classified according to the temperature of the metal rolled.
Steel rolling process flow sheet.
If the temperature of the metal is above its recrystallization temperature then the process is.
In short cold rolling results in a final metal sheet that is more accurate in terms of dimensions and properties than the one that is obtained from hot rolling process.
Another interesting defect that can occur in flat rolling is alligatoring where the work being rolled actually splits in two during the process.
It is one of the most widely used among all the metal working processes because of its higher productivity and lower cost.
In sheet metal industrial practice a sheet may be passed through a series of leveling rolls that flex the sheet in opposite directions to flatten it.
Rolling is defined as the reduction of the cross sectional area of the steel piece being rolled or the general shaping of the steel products through the use of the rotating rolls.
The metal sheet has a smoother surface and the strength of the steel is also increased.
