In the production of the white heart malleable cast iron, in practice, close puck the white cast iron in a furnace with some iron oxide, and anneal for a long time at a high temperature. To study the mechanism of the decarburisation of the cast iron, two different phenomena ; the action of the gases in the furnace and the migration of the carbon in the cast iron ; shoud be demonstrated. This first report is the study of the action of the gases in the furnace, and the phenomenon about the migration of carbon may be published on the second report. The decarburisation of the cast iron in the furnace be taken place on the meaning of the oxidation of the carbon in the cast iron and the reduction of the iron oxide by the intermediating action of the carbon monoxide and the carbon dioxide. The writer has studied the action of the mixed gases of the carbon monoxide and the carbon dioxide on the decarburisation in their many different rates of composition, and further studied the change of the components of the gases in furnace during the annealing. And by these experimental results, the writer confirmed the action of the gases in the furnace to be explained by the chemical equilibrium of the iron-carbon-oxygen.
