It's a steel fabrication process involving passing the metal through a pair of rollers. There are two main types of rolling process: Flat rolling the finished product is a sheet. Profile rolling the finished product is a bar or rod. The process always starts with hot rolling. Hot rolling refers to the process of rolling steel at a ...

Aluminium slabs are heated to a temperature of around 525°C and then passed repeatedly through a hot rolling mill until either the required plate thickness is obtained or until the metal is thin enough (generally about 3 mm thick), to be coiled ready for cold rolling the last 3 or 4 hot rolling passes are usually performed sequentially ...

Aug 21, 2012. likes | Views. Rolling mill. Introduction to Rolling. Rolling is a bulk deformation process in which the thickness of the work is reduced by compressive forces exerted by two opposing rolls. The rolls rotate to pull and simultaneously squeeze the work between them. Introduction to Rolling.

For hot rolling of metals they are first cast into ingot moulds of suitable form (rectangular, square or round). The size of ingot depends upon the metal to be cast and the endproduct desired. For hot rolling, the ingot is removed from the mould after solidification when it is hot and placed in the gas fired furnace called soaking pits.

At its most basic principle, a rolling mill is a machine that reduces the thickness of a metal without sacing any of the material meaning material is always displaced and never lost. By design and function, rolling mills do not generate scrap. The process of rolling affects the materials at a metallurgical level and the desired ...

In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change its crosssectional area.. The types of rolls used in rolling mills are depended upon the shape, size, and the gap between the rolls and their contour. Because of workability and limitations in equipment, rolling is done in the ...
