Abstract
The analysis of the ring rolling machine capabilities in providing increased accuracy of ring blanks is performed. The necessity of operator’s participation in controlling the ring rolling machine to achieve the required accuracy even with full automation of the ring blanks manufacturing process is noted. The necessity of controlling the process of cooling of circular blanks after the circular rolling machine to ensure increased accuracy of the circular blanks has been noted. To eliminate the ovality of low rigidity ring blanks after the circular rolling mill it is proposed to use the technology of their controlled cooling and stabilization. The sequence of thermal strain control of the ring blanks during cooling to preserve the achieved accuracy of the “hot” ring after the ring rolling on the “cold” ring after cooling has been developed. The proposed recommendations are intended for the development of technological support for automated ring rolling complex at OJSC “BELAZ”.
