. The hydrogen permeability decreases with increasing EH to a certain extent. An appropriate choice of slag for the ESR process can be obtained. These results also suggest that the hydrogen pick-up in steel... in a continuous increase of hydrogen content during the remelting process. The hydrogen permeability of the slag dominates the resulting hydrogen content of the steel, especially when the remelting is carried out......
