Couplings for steel industry

In a steel plant, there is a necessity for the reliability and high performance of machinery and equipment.  Couplings, serving as vital transmission parts, are no exception to meet higher and more stringent quality requirements needed for the steel plant’s equipment and machinery.

Function:
It used to transfer rotational movement from one shaft to another. Couplings are used to connect two shafts for torque transmission in varied applications. Couplings are capable of transmitting axial thrust loads between machines and any axial growth that may occur due to high temperature.

Types of coupling
Couplings are normally classified in two ways. The classification of couplings is rigid coupling and flexible coupling.

Rigid couplings are used for shafts having no misalignment. Rigid couplings are of following types:

• Sleeve coupling

• Sleeve coupling with taper pins

• Clamp coupling 

• Ring compression type couplings

• Flange coupling 

Flexible couplings are more commonly used to transmit driving torque between a prime mover and a rotating element of the equipment. Flexible couplings are of following types:

• Elastomeric couplings

• Metallic membrane couplings

• Miscellaneous couplings

Rolling process in Steel rolling plant

Rolling of steel is one of the most important manufacturing processes for steel. Steel 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.

The initial rolling of steel is done in a hot rolling mill where blooms and slabs are rolled down to various rolled products such as plate, sheet, strip, coil, billet, structures, rails, bars and rods. Steel rolling can produce a wide range of products. The width of a rolled product can vary from a few millimeters to several meters while the thickness can vary from 0.1 mm to more than 200 mm. The rolled section can be square, rectangular, round or shaped sections.

Rolling of steel is done not only to achieve the desired cross section but also to get the desired properties of steel. Rolling of steels imparts strength and favourable grain orientation. Further heat treatment processes incorporated during controlled rolling helps in modification of steel microstructure to give the steel desired properties.
