Steel Rolling Process Flow Sheet

In metalworking rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform.

Steel rolling process flow sheet.

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. The metal sheet has a smoother surface and the strength of the steel is also increased. If the temperature of the metal is above its recrystallization temperature then the process is. 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. 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 materials commonly rolled are steel copper magnesium aluminum and their alloys. 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.

The concept is similar to the rolling of dough rolling is classified according to the temperature of the metal rolled.
