This paper concerns the mathematical modelling and numerical solution of thermoelectrical phenomena taking place in an axisymmetric induction heating furnace. We formulate the problem in a two-dimensional domain and propose a finite element method and an iterative algorithm for its numerical solution. We also provide a family of one-dimensional analytical solutions which are used to test the tw...

In case of the currents asymmetry analysis for an induction furnace – symmetrizing circuit connected in a Steinmetz scheme, one of the most important aspects is represented by the negative asymmetry coefficient. This one can be determined knowing the positive sequence and the negative sequence components and the initial parameters R0 and X0 of the induction furnace. The testing algorithm follow...

introduction: it is important that biological and health effects from the induction of currents and fields in the body by extremely low frequency (elf) fields are fully explored to determine the effects produced at the molecular, cellular and organ levels. the objective of this study was to evaluate the intensity of elf electromagnetic fields and its probable relationship with hematological cha...

laboratory and industrial scale experiments are made on the application of sponge iron pellets and briquettes for the production of cast iron and steel in different melting systems, such as electric induction furnace, electric resistance furnace and fuel-fired crucible furnace. effect of various variables such as specifications of sponge iron, temperature of the molten metal and the method of f...

The use of linear graphs in the development a mathematical model metal melting an induction crucible furnace allows to determine temperature and control excess main parts furnace. In addition, if it is necessary optimize thermal mode operation according presented graph conversion method, any part with desired parameters can be obtained.
