Originální abstrakt

Corrosion resistant 13% Cr and 1% Ni cast steel are used to produce castings for the Kaplan, Pelton and Francis turbines. These cast steels have also a satisfactory cavitation resistance. The oxidation re-melting process, where oxygen is blown into the bath, was elaborated in order to reduce the gas content (hydrogen and nitrogen) in re-melted corrosion-resistant 13% and 1% Ni steel scrap. This technology was tested on and elaborated for twenty-five melts, with special regard to oxygen-blowing conditions, mechanical properties (verified by the impact test) of the cast steel, and suppressing the formation of gas holes in the castings. Basic electric arc furnaces were used in the oxidation re-melting process of steel scrap.
