Rolling is a Metal forming process that is one of the most important manufacturing processes in modern metalworking industry. It is used for shaping the metal by passing it through one or more heavy rollers. Rolling mills are generally incorporated with the steel industry. Modern rolling techniques are mainly classified into two types.

Cold Compact Mill (CCM) Pickled coils are rolled in twin stand cold rolling mill where they are processed into a specified thickness. Generally, the rolling reduction ratio is 50% to 90%. The critical point at this stage of the process is to maintain uniform and precise flatness throughout the entire length of the coil. Unique Features

2005. A. Mill scale consists primarily of magnetite, Fe 3 O 4, of characteristic blue-gray "steely" color. An extremely thin outer film of hematite, Fe 2 O 3, is invisible to the naked eye. The inner portion of the magnetite contains fine metal grains and sometimes, residual black FeO (see below), which contribute to the roughness of descaled metal.
At a rolling mill, blooms and slabs are further rolled down to intermediate parts such as plate, sheet, strip, coil, billets, bars and rods. Many of these products will be the starting material for subsequent manufacturing operations such as forging, sheet metal working, wire drawing, extrusion, and machining.

tire, called a "green tire" at this point. When a green tire is finished, the metal drum collapses, allowing the tire assembler to remove the tire. The green tire is then taken to a mold for curing. 1 The first step in the tire manufacturing process is the mixing of raw materials to form the rubber compound.

The large sheets are cut to width, rolled and transported to the assembly area where all the components will come together. At the same time as the raw rubber is transformed into the tread and plies, the creel room equips the tire with its basic strength. Fine steel wire goes into the manufacturing of belts for the steel-belted radial tire.
The same storage system houses the hot-rolled coils used as raw material for the line, all the cold-rolled coils waiting for the next processing phase, and finished and packed products ready for delivery. This removes the need for many separate storage units located around the mill complex.
Tire building begins on a revolving drum. The operator is a highly skilled craftsman who takes the previously calendared cut fabric (called a ply) and wraps it around the drum. After the appropriate number of plies have been applied to the revolving drum, a bead bundle is placed on each edge. The fabric is crimped over its edges.
In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill & ball mills, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.
3. Kiln shell structure: Kiln shells are made with structural rolled steel plate, such as A.S.T.M. A36. The tensile strength of this type of steel at room temperature is 50,000 to 80,000 psi. As stated before shell strength is measured at a room temperature. Figure-1 is showing how shell strength drops
