Abstract:
High temperature vacuum furnaces for heat treatment typically have operation powers of several hundred kilowatts. They are generally equipped with a fast-cooling system that has to assure that cooling rates, required for certain heat treatment processes, are uniformly met in the whole load. In this contribution thermo-electric and thermo-fluid dynamic analyses of a high temperature vacuum furnace with a refractory metal hot zone are applied to show potentials for energy savings without losing cooling efficiency. The simulation results are validated by experimental data. The results show that an optimization of the gas system allows energy savings of up to 20 % without losing cooling efficiency.
