Abstract
The problem of nickel alloys production is to refi ne the metal and to safe alloying elements and nickel. The aim of this work was to create a model of behavior of all components of complex alloys during melting in the vacuum induction furnace in a deep vacuum. The act of evaporation was taken as a limit stage. The fl ow of each component of the alloy in gas phase under these conditions was determined with the Langmuir equation. The model is adequate to predict the evaporation of components in complex alloys based on nickel during smelting in a vacuum induction furnace. The algorithm providing the calculation of mass and composition variation in time of nickel-based alloys during refi ning in a vacuum induction furnace with selected capacity, residual pressure and temperature is presented.
