English to Russian Tech/Engineering Metallurgy / Casting RH process etc.

the final hydrogen content in steel at the end of RH treatment depends on the pressure of the vacuum vessel, the amount of lift gas and the CO gas development. At higher initial hydrogen contents, the drop of hydrogen is stronger. This phenomenon is due to the fact that for high hydrogen contents there is a high difference between the hydrogen partial pressure of the steel bath and the vacuum atmosphere in the RH-vessel. If this difference is high, a high potential difference is present and a faster reaction **towards** the equilibrium will be achieved, which enhances the hydrogen removal.
