Brem V. Interphases distribution of hydrogen in (gas) - (ftoride-oxide melt) - (metallic melt) systems

It have been theoretically sought and developed a new method of finding the content of hydrogen in ftoride-oxide systems (slags, fluxes). We developed a method of quantitative estimation of hydrogenic permeability by the means of which a study of standard and experimental ftoride-oxide slags hydrogenic permeability was provided. Were studied the solubility (HF+Н2О) and molecular hydrogen at this melts, forms of its representation and gas phase balanced compositions. We found the coefficients of hydrogen molecular diffusion at ftoride-oxide meltings which composition is typical for electroslagging. We explored the kinetics and mechanism of interphases hydrogen distribution processes at the system gas-flux-metal where applicable to the technology of steels electroslag remelting. Was determined that limited interphase reaction is reversible and gives principal possibility for electroslagging both with additional hydrogen dissolving in metal and with significant extraction hydrogen from metal.
