Abstract

The invention discloses a converter bottom blowing gas supply branch pipe differential control method and system based on image recognition, and belongs to the technical field of converter steelmaking. The erosion sunken depth of each bottom blowing gas supply element is determined by measuring the thickness of the converter bottom, ventilation states of the bottom blowing gas supply elements are judged and marked by identifying morphological characteristics of ventilation black holes of the bottom blowing gas supply elements and judging the damaging states, and the corresponding converter maintenance information is sent out according to different states; and according to control of branch pipe control parameters of the bottom blowing gas supply elements and calculation of control parameters of the single-branch bottom blowing gas supply elements, differential control of all the bottom blowing gas supply elements is achieved by issuing and executing control instructions of the single-branch bottom blowing gas supply element, and the comprehensive purposes of prolonging the service life of the bottom blowing gas supply elements, inhibiting rapid damage of individual bottom blowing gas supply elements, strengthening the synergistic stirring effect among the bottom blowing gas supply elements, stabilizing the bottom blowing stirring effect of a converter, improving the production efficiency of the converter, improving the quality of molten steel and the like are achieved.

Description

technical field [0001] The invention belongs to the technical field of converter steelmaking, and more specifically relates to a differential control method and system for bottom blowing gas supply branch pipes of a converter based on image recognition. Background technique [0002] Converter top-bottom combined blowing steelmaking is to blow oxygen into the molten iron from the upper part of the converter molten pool through the oxygen lance, and blow nitrogen or argon gas into the molten pool from the bottom of the converter through the bottom lance to stir the molten pool. In the converter smelting process, with the increase of the bottom blowing flow rate, the stirring intensity and mass transfer efficiency of the molten pool increase, which not only promotes the balance of slag and steel, improves the kinetic conditions of carbon-oxygen reaction in the furnace, but also improves the utilization efficiency of top-blown oxygen , to reduce the carbon and oxygen accumulatio...
