Rolling is the most important and widely used metal forming process because of its lower cost and higher productivity. The rolling process is best defined as the shaping of metals into semi-finished or finished forms by passing between rollers rotating in opposite direction.
Just like any other metal forming process, rolling works in the same way. The deformation takes place when a compressive force is applied by a set of rolls on ingot or any other product like billets, blooms, sheets, slabs, plates, strips, etc.
This deformation decreases the cross-section area of the metal and converts it into the required shape. The main purpose of rolling is to decrease the thickness of the metal. Steel, magnesium, aluminum, copper, and their alloys are the materials commonly rolled.
As a result of the friction between the rolls and the metal surface, the metal is subjected to high compressive stresses.
High production rate, grain structure, and surface-finish are obtained, which makes it a most suitable metal forming process for large length cross-section workpieces like plates and sheets of steel and aluminum for other works and structure. However, the high set up cost of the rolling machine makes it an alternative process. The rolling process is done both hot and cold, which is accomplished in rolling mills.
A rolling mill is a complex machine having two or more supporting rollers, working rollers, drive motor, roll stands, working rollers, coupling gear, flywheel, etc.
According to the requirement of the process and technical issues, these rolling machines are available in different shapes and sizes. Each rolling mill consists of a minimum of two rolls. As per the process requirement, these numbers can extend even. Depending upon the shape of the rolled product, the rollers may be grooved or plain. The shape of the metal changes gradually during the period in which it's in contact with the two rollers.
Compared to forging, rolling is a more economical method of deformation when metal is required in long lengths of uniform cross-section. The hot rolling process occurs with the initial breakdown of ingots into billets and blooms. This is followed by further hot rolling into the sheet, plate, bar, rod, rail, and pipe. It's done at the above recrystallization temperature and used for large deformations. Hot rolling gives residual stresses free product, but due to scale formation, it gives poor dimension accuracy and surface finish.
A major role in the industry is played by the cold-rolling of metals by providing sheet, strip, foil with high mechanical strength, good surface finish, along with dimension accuracy.
The cold rolling which is done to get the final product is done at below recrystallization temperature. We shall discuss here the types of rolling process and its applications in the manufacturing industry.
In this process, the threaded dies are fitted on cylindrical rollers of the rolling machine. The cylindrical blank presses the threaded roller and roll against the faces, which displace the material and form threads on the cylindrical blank. The thread-rolling process has the benefit of generating threads with high strength due to cold working , without any material loss scrap and good surface finish.
The shape rolling is used to cut different shapes on the metal workpiece. It does not involve any significant change in thickness. It's used to roll construction shapes such as I-beams, L-beams, and U channels, rails for railroad tracks, and round and square bars and rods, etc.
The applications of shape rolling are -. Ring rolling is a type of hot rolling that increases the diameter of a ring. Two rollers i.
Due to the rotation of the roller, the ring rotates and the rollers then start moving close to each other, with a decrease in ring thickness and hence this results in an increase in its diameter. To maintain the height of the ring, a pair of edge rollers are used, which does not allow metal flow in the direction of height.
This process gives material finish and high accuracy. Common applications of ring rolling include -. Tube piercing is another rolling process in which you can find a stationary mandrel at the center of tube and cavity form, due to tensile stress in a cylindrical rod when subjected to external compressive stress.
Two rolls are rotated in the opposite direction in this process which compresses the tube and feeds it against mandrel which creates a hollow cavity in it. This process is used to make seamless hollow tubes of a thick wall. Also called cross rolling, which is used to produce table knives, leaf springs, tapered shafts, and hand tools.
In this process, both rollers rotate in the same direction and the heated bar is cut to length and is fed transversely between rolls. Usually, circular wedge rolls are used in the transverse rolling. This is a process similar to roll forging. Typically used for making ball bearings.
In this process, round wire or bar is fed directly into specially designed rollers which continuously form spherical balls by rolling action. Used for the mass production of small size spherical balls. In roll bending, a cylindrical shaped product is produced from plate or steel metals.
The rolls change shape during rolling because of the forces acting on them, which tends to bend the elasticity of the rolls during rolling. If the elastic modulus of the roll material is high, then the roll deflection would be smaller.
Compared to its edges, the rolled strip tends to be thicker at the center. We can avoid this problem by grinding the rolls in such a way that their diameter at the center is slightly larger than at their edges. This is the most basic form of rolling in which the starting and end material both have a rectangular cross-section. The material is fed in between two rollers, that rotate in opposite directions. The two rollers in flat rolling are called working rolls. The gap between the two rolls is less than the thickness of the starting material, which causes the deformity of it.
The material, which is pushed through due to the friction at the interface between the material and the rolls, even elongates due to the decrease in material thickness. However, the friction between the rolls limits the amount of deformation possible in a single pass. The rolls just slip over the material and do not draw it in if the change in thickness is too great.
The workpiece is brought above the recrystallization temperature with the help of heat, which performs the heat treatments to avoid any subsequent heat treating.
Controlling the nature, size, and distribution of various transformation products; production of a fine grain structure; controlling the toughness; inducing precipitation hardening are some of the types of heat treatments included. The entire process must be closely monitored and controlled, to achieve this. The deformation levels, cool-down conditions, starting material composition and structure, the temperature at various stages are the common variables in controlled rolling.
Better mechanical properties and energy savings are the benefits of controlled rolling. Publish Your Article.

Plastic Vs. Metal Fabrication - Advantages and Disadvantages
The metal working is an ancient art. There are witnesses that, already millennia before christ, metals were known and worked. It is easy to understand that it is extremely complex. This article is focused on tracing a synthetic history of sheet metal and its machining. We must first of all distinguish three fundamental aspects, distinct but deeply interconnected: -the production of the raw material, in particular steel; -the thin sheet fabrication; -its machining. Raw material production The material working by plastic deformation started in the prehistory through the cold use of metals present in nature at the native state, like gold and silver. Afterwards, with the introduction of the possibility of melting materials, they passed to copper, bronze and more recently steel.

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. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its recrystallization temperature, then the process is known as hot rolling. If the temperature of the metal is below its recrystallization temperature, the process is known as cold rolling. In terms of usage, hot rolling processes more tonnage than any other manufacturing process, and cold rolling processes the most tonnage out of all cold working processes. Most steel mills have rolling mill divisions that convert the semi-finished casting products into finished products. There are many types of rolling processes, including ring rolling , roll bending , roll forming , profile rolling , and controlled rolling.

Descriptions of manufacturing processes 1. This analysis had to identify the amount, type and quality of energy required so as to identify possible energy savings compatible to the respective cost-benefit analysis. The following process descriptions of the manufacture of sawn timber, plywood and particleboard are of a general nature and should provide the reader with a broad outline of the production processes involved in the mechanical wood-based industry and the role in which energy plays a part. Sawmilling is a less sophisticated activity of the mechanical forest industries. It implies a certain number of operations from handling and transportation of logs to timber drying, sorting and classification which require different types of energy. Whereas in developing countries most of the processes are highly mechanized and the energy requirements are met basically with the generation of a few kW to drive the main saws.
