What is produced in a Bessemer Converter?
Bessemer process testing and helped him draw up a patent that was taken out in May, 1878. Sidney Gilchrist Thomas's invention consisted of using dolomite or sometimes limestone linings for the Bessemer converter rather than clay, and it became known as the 'basic' Bessemer rather than the 'acid' Bessemer process. An additional advantage was that the processes formed more slag in the converter, and this could be recovered and used very profitably as a phosphate fertilizer. In 1898, "Scientific American" published an article called "Bessemer Steel and its Effect on the World" explaining the significant economic effects of the increased supply in
Bessemer process the lighter slag was left behind. The conversion process, called the "blow", was completed in approximately 20 minutes. During this period the progress of the oxidation of the impurities was judged by the appearance of the flame issuing from the mouth of the converter. The modern use of photoelectric methods of recording the characteristics of the flame greatly aided the blower in controlling final product quality. After the blow, the liquid metal was recarburized to the desired point and other alloying materials were added, depending on the desired product. A Bessemer converter could treat a "heat" (batch of hot metal)
