Why is Metal Rolling Important in Metalworking Industries

Jun 22nd 2015 at 10:54 PM

The development in technology has made great changes in rolling mechanism as in any other field. Perfection in design is always considered an important thing. With lot of roofing sheet used today, rolling machineries has also became well known even in households today. With a number of machineries, the selection of the perfect one is only based on your usage.

Quality and perfection is always the greatest thinks to be noted in any production industry. When it comes to house hold production, the importance of perfection doubled in its importance. No matter for what, industrial or domestic purpose perfection is always important.

What is rolling?

Rolling in metalworking is a process used to get uniformity throughout the metal surface. We do similar process a rolling a dough to get the work done. In this technique the metal will be passed through more than one rolls, to attain uniform thickness throughout the surface. There are two main type of rolling technique used today, they are:

• Cold rolling.
• Hot rolling.

The difference between the both is nothing but in their operating temperature. There are lot of machineries available today with different technologies. The latest technology used in rolling is in IBR roof panel roll forming machines implementing the advanced IBR technology. With development in technology we today have a lot of machineries, and process based on them. The selection of the perfect is based on our mode of usage.

The process

There are lot of process used in rolling, each of the different in the materials used. The selection of the perfect process will be based on the type of material being rolled, or the output product required. The main types of rolling mechanisms are:

• Roll forming; this method is mainly used to obtain longer length products or for larger quantity production. It includes continuous bending operation by passing through consecutive rolls. There are machineries available with different number of rollers, each with its own advantages.

• Flat rolling; this is considered as the most basic rolling mechanism. This is used for rolling of materials with a rectangular cross-section. It mainly includes two rolls, each rotating in opposite direction. The distance between the rolls will be adjusted to be less that the product thickness, this will help to deform the material. Often the rolls will be heated, and lubrications will also be used.

• Foil rolling; these are special mechanisms used to produce foils, and hence the name. As the product will have very small thickness special rollers have to be used. Aluminium foils are the main thing produced by this method.
The word forming is used instead of rolling, as a heavy press is used to form sheets.
