On the Physico-Chemical Research of the Metallurgical Reaction of Charcoal (4th Report). On the Reaction of the Steels with Semi-Water Gas

Sôsuke Uchida


Abstract:

The reaction of the steels with Semi-water gas produced by the combustion of charcoal in wet air were investigated, especially, on the bright heating and carburizing of steels, and the following results were obtained: (1) The curve of oxydation and reduction of Fe was plotted with the straight line in the equilibrium diagram of CO/CO2 and H2/H2O of semi-water gas.(2) These gases had strong carburizing power for steels when CO2 and H2O were small or removed. (3) When these gases was including their carburizing compositions were heated at a low temperature, soot was deposited by the following reaction in order to reach the equilibrium state at its temperature.

CO=C+CO2      CO+H2=C+H2O
