Abstract

The invention relates to the technical field of steelmaking in the metallurgical industry, and discloses a thermal image tracking and control method for a high-temperature smelting soft stirring system. The method includes: firstly, collecting thermal image data of the liquid level in the steel ladle through the high-temperature infrared thermal image unit, and transmitting the data to the system host; then, automatically detecting an image and temperature distribution formed on the surface of the molten steel by bottom blowing, and partitioning the thermogram by image processing; calculating the area, the highest temperature, the average temperature and the like of a high-temperature region of the molten steel according to the partitions, analyzing the rolling intensity of the molten steel in the high-temperature region, and establishing a corresponding relation between the input image and the output bottom blowing pipeline gas flow; establishing a bottom blowing control model through a fuzzy control method, obtaining a negative feedback closed loop for controlling flow, and calculating and outputting a reasonable target flow value; and finally, enabling the electric cabinet to controls a gas valve of the steel ladle bottom blowing pipeline according to the target flow value, so that the gas flow of the steel ladle bottom blowing pipeline is controlled. According to the invention, intelligent control of ladle bottom blowing is realized.

Description

technical field [0001] The invention relates to the technical field of ladle bottom blowing, in particular to a thermal image tracking and control method of a high-temperature smelting soft stirring system. Background technique [0002] In the converter steelmaking process in the metallurgical industry, after the converter smelting is completed, the molten steel needs to be poured into the ladle for bottom blowing argon stirring. Although this process is short, it plays a non-negligible role in the quality assurance of the subsequent molten steel products. Steel ladle is also called steel ladle, which is mainly used in steelmaking plants and foundries to undertake molten steel and perform pouring operations before open hearth furnaces, electric furnaces or converters. With the rapid development of out-of-furnace refining, especially the wide application of various refining furnaces, the role of the ladle has attracted more and more attention; during high-temperature smelting...
