This study analyzes the impact of operational parameters of hot rolling mill in the degradation process of a roll surface by thermal fatigue. A methodology was developed to determine a coefficient that could identify when operational parameters become crucial to initiate this degradation process. This new coefficient, named the surface damage coefficient (κ), is correlated with the calculated ...

Abstract A mathematical model of a striplooper system of a hot strip tandem rolling mill is developed using Hamilton's principle and the Galerkin weighted residual method. Several nonlinearities are considered and the effects of bending and dynamic forces on the accuracy of the model are studied. Based on the model, an estimator for the strip tension is proposed.

The rolling process is shown in Fig. : 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.

Abstract. The theory of rolling metals has been adequately developed since the mid 1940's. Of the popular theories, the complex formulations are accurate over a large range of rolling conditions, and the approximate formulations tend to be accurate only on a narrow range. This paper covers the development of an approximate formulation of the Orowan (1943) rolling theory that is applicable ...
