Description

technical field [0001] The invention relates to a method for dynamically tracking the gas flow center and monitoring the gas utilization rate. Background technique [0002] Blast furnace production is a series of complex physical, chemical and heat transfer reactions carried out under high temperature and high pressure conditions. Because its internal smelting is a typical "black box" operation, it is difficult to realize real-time accurate positioning and control of the blast furnace throat gas flow center distribution. A reasonable central distribution of the gas flow is an important condition to ensure the stable decrease of the charge in the blast furnace, and the normal progress of chemical reactions and heat exchanges. At present, infrared cameras are installed in the blast furnace production of iron and steel enterprises. The purpose is to observe the position and changes of the blast furnace gas flow center in real time. The furnace director conducts production regu...

Problems solved by technology

The existing technology generally only extracts features from a small amount of infrared images under abnormal furnace conditions, and fuses them with the cross temperature measurement data to obtain the temperature field distribution of the material surface under different furnace conditions. It fully represents the complex blast furnace conditions, and there is no accurate measurement of the specific distribution characteristics of the gas flow center and the impact of the center distribution on the blast furnace
