Energy consumption estimation method based on extended rist operating line of blast furnace

Abstract

The application discloses an energy consumption estimation method based on an extended blast furnace Rist operation line, which is based on the calculation of the blast furnace Rist operation line, organizes and calculates the blast furnace process data, the data including the carbon content dissolved in the molten iron and the solid carbon content in the furnace dust ash; the carbon content dissolved in the molten iron and the solid carbon content in the furnace dust ash are substituted into the calculation of the blast furnace Rist operation line, the horizontal and vertical coordinates of points A and E are calculated according to the measurement results; the AE operation line is obtained by connecting the points A and E, the slope of the AE operation line is converted into the carbon ratio of the blast furnace smelting, and then the carbon consumption of the blast furnace fuel is represented; thus, under the condition of considering hydrogen reduction, the carbon content dissolved in the molten iron and the solid carbon content in the furnace dust ash are identified as fixed carbon, the carbon dissolved in the molten iron and the solid carbon in the furnace dust ash are regarded as active carbon elements in the blast furnace ironmaking, and are substituted into the calculation of the blast furnace Rist operation line, so as to reduce the calculation error of the carbon consumption and expand the capacity of the blast furnace Rist operation line.
