The present invention relates to an electric melting fireproof material oxygen-blowing method, which comprises pouring a material to an electric melting furnace, increasing the temperature inside the furnace to 2000-2400 DEG C to make the furnace material melt, and other steps, and is characterized in that during the inside-furnace temperature increase process, compressed air after oil and water separation and oxygen are conveyed into the furnace through the gas inlet arranged on the bottom portion of the electric melting furnace, and the pressures of the compressed air and the oxygen respectively are 0.1-2.0 MPa gauge pressure value. According to the present invention, during the furnace material temperature increase process, the compressed air after oil and water separation and the oxygen are input into the furnace through the gas inlet arranged on the bottom portion of the furnace so as to substantially promote the volatilization of the low-melting substance in the furnace material and accelerate the flowing of the melting furnace material, such that the porosity of the produced fireproof material product is reduced, the product purity is improved, the problem of the shortened service life due to erosion, infiltration, shedding and peeling-off during the fireproof material product use process is solved, the environmental pollution caused by the waste is reduced, and the raw material is saved.
