ABSTRACT
The gases removal from Fe-C (C content 0.8 and 2.0 wt %, Fe – the balance) melt was determined by reducing the melt weight. Weight loss could occur with the removal of iron, carbon, hydrogen, nitrogen and oxygen. The constancy of the Fe-C melt (2% wt.) weight at the end of the experiment in an electric field and without it excluded iron from the number of elements to be removed. The removal of the elements (C, H2, N2, and O2) is calculated by the mass of monatomic ions taking into account the influence of experimental conditions. The weight of a monatomic ion of an element is determined by the amount of electricity required for its transfer, the proportion of ions in electricity and the element atomic weight. The ions proportion in the transmitted electricity is determined from the ratio of the ion velocity to the sum of the electron velocity. The required amount of electricity for the transfer of an element monatomic ion is calculated in relation to the product of the fraction of the element ions in the past electricity that flowed and its atomic weight to the sum of their values of all participants in the transfer. The weight of the monatomic ions of the removed elements when multiplied by the determined number of atoms is equal to the melt weight change. The removed gases (C, H2, N2, and O2) were found by the determined number of their atoms from the equality of masses during the experiment and in short periods of experiment conducting. The weight of gases monatomic ions during the experiment is greater than the weight of such ions in short periods.
During the experiment hydrogen was removed in the form of Н3+ ions (0.0658•10-3 g) and nitrogen – N3+ (7.2396•10-3 g) from the Fe-C melt (0.8 wt %). The deviation of ions mass from the weight change was + 0.07%.
Hydrogen was removed from the Fe-C melt (2 wt %) in the form of Н10+ ions (0.180•10-3 g), nitrogen – N2+ (4.0208•10-3 g), oxygen О5+ (13.04268•10-3 g). The deviation of their mass from the weight change was 0.03%. Polyatomic ions were removed from the melt gases. Carbon was not removed, there was no carbon in the surface layer.
