The card carries these facts from its Wikipedia article.
- Blowing oxygen through molten pig iron lowers the carbon content of the alloy and changes it into low-carbon steel.
- The process is known as basic because fluxes of calcium oxide or dolomite, which are chemical bases, are added to promote the removal of impurities and protect the lining of the converter.
- The process was invented in 1948 by Swiss engineer Robert Durrer and commercialized in 1952–1953 by the Austrian steelmaking company VOEST and ÖAMG.
