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 in its cross-sectional 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 …
5. Cluster Rolling Mills: In this type of rolling mill, there are two basic roles that are backed up by two or more rolls which are bigger than those two basic rolls. These backed up rolls give more pressure to the basic rolls to heavily press the strip.

Subaru's EJ251 and EJ252 were 2.5-litre horizontally-opposed (or 'boxer') four-cylinder petrol engines. For Australia, the EJ251 engine was first introduced in the Subaru BE/BH Liberty in 1998 and subsequently offered in the BH Outback, GD/GG Impreza RS and Subaru SG Forester. For the Subaru BL/BP Liberty and BP Outback, the EJ251 was replaced by the EJ252 engine.
for rolling. They are then rolled to smaller thickness by passing over a series of rolls, and finally made into a rolled coil of steel. The coil is shipped or sent to a cold mill. The cold roll mill reduces the thickness further. Annealing and galvanizing is done on the steel to meet the specifications of its intended use.

The primary finishing refinement for sheet steel is being further hot-rolled in the rolling mills. Rolling mills are just a series of rollers and hot-rolling just means that the steel is at a high temperature while it is being rolled. Before the slabs can be rolled, they need to be reheated to about 2400 degrees Fahrenheit and then need descaled.
