Abstract
The problem of melting the iron-based alloys in a vacuum induction
furnace is to provide a metal refi ning while maintaining alloying elements and ensuring the specifi ed composition. It is impossible to solve this problem without the appropriate quantitative description of deep vacuum refi ning processes. The objective of the research was to create an adequate model of iron-based alloy components evaporation in deep vacuum. The act of the component transition into the gas phase is taken as the limiting stage of the vacuum evaporation process. The fl ow of each alloy component was calculated with Langmuir’s equation. The model developed by the authors gives the adequate results of prediction the iron-based high alloy components evaporation during smelting in a vacuum induction furnace with deep vacuum. The algorithm developed in this work makes possible to calculate the alteration of the alloy composition and the mass of iron during refi ning in a vacuum induction furnace with selected capacity, residual pressure and temperature
