The author proposes a process for making of pure iron by a duplex process of Bessemer converter and high frequency electric furnace as an economical industrial process. The molten pig iron melted in a cupola furnace was blown in the basic or acid bessemer converter depending on the phosphorus content to eliminate the impurities. The carbon content in the blown metal was kept under 0.04 per cent. The refining of the blown metal was carried out in the high frequeney electric furnace with acid slag. The final metal obtained contained very small impurities and it is recognized that it is not difficult to make the carbon content of iron under 0.02 per cent and to deoxidize the metal by acid slag to obtain the pure iron with good mechanical properties.
