THERMAL CALCULATION FOR MAGNETIZATION COILS OF ELECTROMAGNETIC SEPARATOR

The degree of electromagnetic separator coil heating determines the service life of isolation fabrics of the construction and consequently, the service life of the whole coil, more often, the entire device. Therefore the objective was set to calculate stationary temperature field in the axisymmetric magnetization coil, that had the shape of a hollow cylinder, and to check with the correspondence between coil temperature and regulatory documents. The characteristic of thermal calculations is that coils were calculated with the software complex ELCUT and compared with the experimental data obtained during the coils testing. The analysis of the stationary temperature field was done with a simplified model. The simplification was based on several assumptions. An actual separator, which was composed of heterogenous parts with different thermal and technical properties, was referred to as a homogenous body possessing infinitely great thermal conductivity. The latter property means that the temperature in all the points of the body examined has been always the same. The temperature of the environment is constant during heating. The magnetization coil thermal capacity does not depend on the temperature of the environment.
