We discuss several drive mechanisms for the working stand in periodic cold-rolled pipe mills. This paper focuses on identifying opportunities to increase mill capacity and modernize existing periodic cold-rolled pipe mills. We provide a comparative analysis of a variety of systems for equilibration of the dynamic forces in the working-stand drive mechanism.
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.
