Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Aim. This article is intended to develop a technique for monitoring the lining state of induction channel furnaces for melting
oxygen-free copper by monitoring changes in the distribution of thermal fields in their lining and carrying out a comparative
analysis of the developed technique with the existing one that controls the electrical resistance of the melting channel of the
furnaces. Technique. For carrying out the research, the theories of electromagnetic field, thermodynamics, mathematical physics,
mathematical modeling based on the finite element method were used. Results. A technique for diagnosing the lining state of the
induction channel furnaces for melting oxygen-free copper has been developed, which makes it possible to determine the
dislocation and the size of the liquid metal leaks by analyzing the temperature distribution over the body surface both the inductor
and the furnace. Scientific novelty. The connection between the temperature field distribution on the surface of the furnace body
and the dislocation and dimensions of the liquid metal leaks in its lining is determined for the first time. Practical significance.
Using the proposed technique will allow to conduct more accurate diagnostics of the lining conditions of the induction channel
furnaces, as well as to determine the location and size of the liquid metal leaks, creating the basis for predicting the working life
of the furnace |
