The present study made some consideration on the results obtained at the Osaka Arsenal with regard to the melting operation of the high-grade steels using the acid electric furnace, following the former report. The authors equalized the temperature of the melt by full agitation, and determined it with an optical pyrometer. Taking it for the reaction temperature, they dealt with the carbon reaction, the silicon reaction and the manganese recation and the quantity of "sbnims." Thus they perceived that the CO gas always evaporates from the steel melt even at the static state without movement of the steel melt at the deoxidation period and the carbon reaction is always proceeding and that the flotation of the product of deoxidation depends on the adsorption of the gas evoloved as well as on the difference of densities of the steel melt. The flotation velocity was found to be fairly great. Moreover, the authors referred to the fact that the quality and purity of the acid furnace steel mostly depend on the oxidation rate {(FeO)×C}.
