1. a Calculation of Solubility method for the nitrogen of nitride smelting high-nitrogen steel, is characterized in that:

  • When nitrogen bring into massfraction that the massfraction of the nitrogen of molten steel and nitride bring the nitrogen of molten steel into be less than the saturation solubility of nitrogen in molten steel time, the solubleness of nitrogen in steel equals nitrogen and brings the massfraction of the nitrogen of molten steel into and nitride brings the summation of the massfraction of the nitrogen of molten steel, the difference with the massfraction of the nitrogen overflowed during solidification of molten steel into;

    When nitrogen bring into massfraction that the massfraction of the nitrogen of molten steel and nitride bring the nitrogen of molten steel into be greater than the saturation solubility of nitrogen in molten steel time, the difference of the massfraction of the nitrogen overflowed when the solubleness of nitrogen in steel equals saturation solubility and the solidification of molten steel of nitrogen;
