The rolling process is shown in Fig. 2.1: Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc.
In a large range of applications, steel must first be processed in a rolling mill before it can be used. Steel used for building a vessel must sustain fatigue due to rolling and other reaction during voyage. The main users of scrapped irons are the local steel re-rolling mills producing MS rods, MS bars, angles and steel sheets for domestic market.

The mill is a reversing mill, allowing the ingot to pass and re-pass through the rolling stand until the desired profile is achieved. Prior to their introduction in late 19th century, large industrial hammers were used to reduce ingots to a suitable size and shape for rolling.
BLOOMS: A Semi-finished product, usually in square (at times in rectangular) section of cross sectional size exceeding 5"x5" (125mm X 125mm). In some of the modern mills, the term bloom is used to cover such products of cross sectional size exceeding 8"x8". These are inputs for producing Heavy sections and Sheet piling section normally by hot rolling.

Hot rolling breaks the grain structures and destroys the boundaries, giving rise to the formation of new structures with strong boundaries having uniform grain structures. Starting materials such as blooms or slabs at an elevated temperature flow from the continuous casting process directly into the rolling mills.
2: Three high rolling mill: It consists of a roll stand with three parallel rolls one above the other. Adjacent rolls rotates in opposite direction. So that the material may be passed between the top and the middle roll in one direction and the bottom and middle rolls in opposite one. In three high rolling mills the work piece is rolled on both ...
ROLLING The rolling mill is equipped with a walking beam furnace with a capacity of 125 tons per hour. Blooms are de-scaled after exiting the furnace, and then proceed through a five stand roughing mill, a six stand intermediate mill, and an eight stand finishing mill. Dimensional control
Various configurations of rolling mills: (d) cluster mill Cluster Mill 22 Variousconfigurations of rolling mills: (e) tandem rolling mill. Tandem Rolling Mill Rolling mills have several stages, where the each stage successively reduces the thickness of the stock until the desired cross section is achieved.
Rolling is a metal forming process in which the deformation takes place under the application of Compressive forces between the rollers. In this article, we are going to discuss a detailed presentation on the Rolling Process with its Principle, Working, Types of Rolling Mills, Advantages, Disadvantages & Applications.
noun. A factory or machine for rolling steel or other metal into sheets. 'Men who work in steel mills, blast furnaces, rolling mills, or other environments of intense heat have a slightly increased incidence of breast cancer (probably due to thermal suppression of androgen production).'. 'It is a world leader in the field of high-pressure ...
If the mill rolls 800,000 tons per year, it runs at an average production rate of 114.16 tons/hour. If the utilization can be improved by 1 %, the available rolling hours is 365 x 24 x 0.81 = 7096.6, creating 87.6 extra rolling hours. At 114.16 tons/hour that is an additional 10,000 tons can be rolled.
Rolling speeds at the finishing mill will be higher than at the roughing mill. Hence rolling cannot be done with stock present in both roughing and finishing mills. Finishing mill rolling of reheated slab: The finishing mill usually has five to seven finishing roll stands, which reduce the thickness of the transfer bar down to the gauge required.

The roughing mill is made up of six independent rolling mill stands, the last four of which incorporate small vertical rolling mills called edgers. Slabs heated in the furnace until they glow bright orange-yellow are rolled through one stand at a time to produce so-called transfer bars suitable for finish rolling. High-pressure water-jet
In a metal rolling process, rolls, stands, bearings, housing, motors, and other mechanical equipment are all a necessary part of the manufacturing operation. The place where all the equipment for metal rolling manufacture is set up is called a rolling mill. Rolling mills often vary in the type, number, and position of rolls.
What Is A Rolling Mill? 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.
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 …
The rolling mills are similar to that used in hot rolling. The cold rolling process has the advantage of providing close dimensional tolerance up to 0.025 mm. It also improves toughness, hardness, mechanical strength, surface finish of the material. Softer metals like tin, silver, gold, aluminum and its alloys undergo cold rolling.
