Steelmaking heat balance control method

The invention discloses a steelmaking heat balance control method which comprises the following steps: S1, calculating and listing a material balance relationship between added materials and products in a steelmaking process according to used materials and listed condition assumptions; s2, calculating a revenue-expenditure balance relationship of physical and chemical heat, consuming the generated surplus heat through ores, and constructing a new heat balance relationship; s3, an end point target is set for the steelmaking type, a steelmaking model is constructed with the purpose of finally achieving the material balance relation and the heat balance relation, and parameter information is listed in the steelmaking model in a table form; and S4, the steelmaking parameters are input into the steelmaking model, and steelmaking guidance parameters are obtained through table look-up. According to the method, the model parameters are corrected according to the actually measured terminal point condition, so that ste
