Original Abstract

High-alloy steel scrap is very often processed by melting in basic electric-arc furnaces via simple re-melt technologies. This technology gradually leads to continued increase in the content of hydrogen and nitrogen in melts and after a certain number of re-melts, hydrogen and nitrogen bubbles begin to form. Especially high-alloy chrome steels for water turbines and high-alloy manganese (Hadfield) steels have a tendency to form such bubbles. The increase in the content of both gases in the re-melting can be significantly reduced by engaging a short but intensive carbon boiling by oxygen blowing. This paper puts forward verified thermodynamic and kinetic conditions of the oxygen blowing into the baths of the re-melts of two different high-alloy steels: chromium steel 13wt% Cr and 1wt% Ni used for the castings of water-turbine parts and pumps and manganese (Hadfield) 13 wt% Mn and 1,3 wt%C steel for castings designed to resist wear connected with high pressures and impacts.
