A 1000 mm wide and 2mm thick mild steel sheet is cold rolled to 1.5 mm thickness. The mean yield strength of the material of sheet is 25 kgf/mm 2. The working roll diameter is 500 mm. Determine the rolling load on the rolling stand if the co-efficient of friction is 0.07. Also determine the rolling torque. Solution: Example 2:
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 equipment, rolling is …

The Manufacturing Process Here is a typical manufacturing process used to produce brass sheet and strip The coldrolling mills are designed to minimize deflection across the width of the rollers in order to produce brass sheets with nearuniform thickness 9 …
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. Rollers may be plain or grooved depends upon the shape of rolled product.
Thread Rolling Figure 13.16 (a) Features of a machined or rolled thread. (b) Grain flow in machined and rolled threads. Unlike machining, which cuts through the grains of the metal, the rolling of threads causes improved strength, because of cold working and favorable grain flow. Figure 13.15 Thread-rolling processes: (a) and (c) reciprocating
Rolling is the process of plastically deforming steel by passing it between rolls. Rolling is defined as the reduction of the cross sectional area of the steel piece being rolled, or the general shaping of the steel products, through the use of the rotating rolls. Rolling of steel is one of the most important manufacturing processes for steel.
• Rolling is the most widely used forming process, which provides high production and close control of final product. •The metal is subjected to high compressive stresses as a result of the friction between the rolls and the metal surface.Rolling process Note: rolling processes can be mainly divided into 1) hot rolling and 2) cold rolling. 3.
Santanu Chakraborty, in Treatise on Process Metallurgy: Industrial Processes, 2014. 6.5 Rolling Mills. The rolling mill facilities were designed to meet the production requirement of Table 1.The rolling mills complex was proposed to include a light and medium merchant mill with breakdown group of stands for rolling blooms into billets and an intermediate in-line heat compensating furnace; a ...
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 rolling mill consists of two rolls 1, 2, and the supporting shafts 3, {1 are geared witheac-h other by wheels 5, 6. The supporting shafts 3, 4 aremade hollow. for passing therethrough heating agents, and they are connected to the supply and escape tubes for the heating agent by stuffing boxes 7 Each roll 1, 2 consists as is known of a set of disks or laminae 10 arranged side by side and ...
