RESEARCH OF THE HEATING PROCESS OF METAL BALLS IN AN INNOVATIVE INDUCTION PLANT

Deals with the study of the process of heating metal balls in an innovative induction plant for in-line axisymmetric heating of metal products with a discrete cross-section area, analyzes the time of heating a metal ball to a given temperature, depending on its parameters and operating modes of the plant, presents the results of modeling processes and experimental studies, as well as their comparison and analysis. To create energetically efficient continuous-action equipment for symmetric heating of spherical metal products to a given depth for heat treatment without oxidation and decarburization is a challenging problem for some industries, including the mass production of milling bodies for ore-dressing and processing enterprises and cement plants, balls for rolling bearings and valves in hydraulic systems, and wear-resistant balls in the backwater gates of deep-well pumps for oil production. Consider plant induction heating of metal balls has a high level of innovation, which is confirmed by patents of the Russian Federation, as well as interest in the development of several industrial enterprises in the Russian Federation (JSC «Oskol electrometallurgical plant» EUROCEMENT group, etc.) and abroad, in particular TENOVA LOI Thermprocess GmbH (Germany) and Magnatech GmbH (Austria).
