Thermal power treatment of step shafts

Abstract

This article reviews the design of thermal power units for performing thermal operations of hardening and tempering of non-rigid parts of the “shaft” type. The authors describe the thermal power treatment technology, the residual deformation analysis and the optimal conditions definition. The units operation principles and algorithms are given. The developed technology and the design of the frame for thermal operations make it possible to maintain accuracy throughout the term of the product use.
