Method for determining adding amount of steel scrap of torpedo ladle

The invention discloses a method for determining the steel scrap adding amount of a torpedo ladle, and mainly solves the technical problems that the steel scrap adding benefit of the torpedo ladle cannot be evaluated and the optimal steel scrap adding amount cannot be determined under the existing conditions. According to the technical scheme, the method for determining the steel scrap adding amount of the torpedo ladle comprises the steps that (1) the temperature loss of molten iron saved by adding steel scrap into the torpedo ladle is calculated; 2) calculating the steel-making cost increment of adding the scrap steel into the torpedo ladle; 3) calculating the heat recovery benefit of the torpedo ladle; 4) calculating the benefit of adding the scrap steel into the torpedo ladle; and 5) determining the addition amount of the steel scrap of the torpedo ladle. According to the method, the adding amount of the steel scrap of the torpedo ladle can be determined according to the market condition change, so that t
