THE RESEARCH OF A STRESSED STATE BY AN ASYMMETRICAL ROLLING OF A BAND IN ROLLS WITH A REVERSE TAPER

Abstract

In the paper the author sets out the results of a stressed state by an asymmetrical rolling of a band in rolls with a reverse taper. The analysis of the results shows that by an asymmetrical rolling of a band in rolls with a reverse tape more favourable conditions of the stressed state are provided. They promote the removal of all internal defects of a blank at the expense of a high hydrostatic pressure, as well as the decrease of an axial tension. That reduces the probability of metal destruction in a lengthwise direction.
