Embodiment Construction

[0023] In order to calculate the antegrade index of the blast furnace more accurately, so as to improve the stability of the operation of the blast furnace, the present invention provides a method for calculating the antegrade index of the blast furnace based on the moving range, such as figure 1 shown, including the following steps:

[0024] During blast furnace production, according to the actual operation experience of smelting experts, select the blast furnace state parameters that affect the forward movement during the actual operation process, including blast furnace feeding speed, blast furnace wind pressure, blast furnace top pressure and gas percentage in the blast furnace ;

[0025] Assign values ​​to various state parameters of the blast furnace, among which, wind pressure, top pressure, and gas percentage in the blast furnace are all assigned based on their respective moving ranges, which refer to the fluctuation of blast furnace state parameters within a period of...

Abstract

The invention relates to the field of blast furnace smelting, and discloses a method for calculating an antegrade index of a blast furnace based on a moving range, which is used to calculate the antegrade index of a blast furnace more accurately, so as to improve the stability of blast furnace operation. The present invention first obtains the state parameters of the blast furnace in real time during the blast furnace production, including the blanking speed of the blast furnace, the wind pressure of the blast furnace, the top pressure of the blast furnace and the gas percentage in the blast furnace; Assign values, wherein, wind pressure, top pressure and gas percentage in the blast furnace are all assigned based on their respective moving ranges, the moving range refers to the fluctuation value of the blast furnace state parameters obtained in the latest period of time; finally through all blast furnace state The assignment and sum of the parameters are used to obtain the antegrade index of the blast furnace. The invention is suitable for blast furnaces in ironworks.

Description

technical field [0001] The invention relates to the field of blast furnace smelting, in particular to a method for calculating an antegrade index of a blast furnace based on a moving range. Background technique [0002] Blast furnace ironmaking is a resource- and energy-intensive process, and its process costs account for about 70% of the total cost of iron and steel enterprises. Under the circumstances of severe domestic iron and steel production capacity and fierce market competition, effective control of ironmaking production costs is the survival of enterprises. Basic conditions. As the blast furnace is a typical reverse reactor of high temperature and high pressure multiphase complex system, it has the characteristics of multifactoriality, nonlinearity, hysteresis and irreversibility. High-temperature physical and chemical reactions are constantly going on inside the blast furnace. The gas flow and solid, reflow zone, and liquid are constantly convectively moving. The...
