Abstract

The analysis of the force pattern at steady-rolling process in the form in which it is applied in the modern theory of rolling is carried out. Inaccuracies in the existing approaches to estimation of the nature of influence, purpose and origin of forces are revealed. It is shown that existing assumptions about the force pattern in the rolling and, in particular, the scheme of forces have to be refined. The force pattern in the applicable form is a statically indeterminate problem and its solution requires additional initial conditions. Development and creation of methods based on volumetric flow of metal, in particular, on the basis of offset volume is considered promising.
