Problems solved by technology

[0008] 2) Due to errors in charge quality, composition, cooling energy, etc. (especially steel scrap), a considerable number of heat "TSC" measurement results deviate from the target. Increased content of molten steel [O] and slag FeO;
[0009] 3) Sub-gun equipment maintenance and measuring probe costs increase production costs;
[0010] 4) It is necessary to reduce the oxygen supply intensity when measuring "TSC", and it takes about 1 minute to measure "TSO" after blowing, and it takes more time to wait for the chemical analysis results of the sample, which prolongs the converter smelting cycle;
[0011] 5) The cost of equipment investment is relatively high
[0012] Although several 100t converter steelmaking plants of state-owned enterprises in China have installed imported flue gas analysis (mass spectrometer) equipment to realize fully automated steelmaking, there are many problems in the mass spectrometer flue gas analysis equipment, and the maintenance of the equipment is large. The response time is long, which brings difficulties to the intelligent steelmaking model technology, so it has not been widely used in domestic steel mills

Description

technical field [0001] The invention relates to the technical field of iron and steel metallurgy, in particular to an intelligent steelmaking system based on converter flue gas analysis technology. Background technique [0002] As we all know, my country is a big steel country, but not a strong steel country. In WSD (World SteelDynamics) annual list of the most competitive steel companies in the world in 2017, Baowu Group ranked No. 1 in China and No. 10 in the world. Compared with foreign steel mills, domestic steel mills currently produce iron and steel products in terms of quality, variety, per capita steel production, and corporate benefits. [0003] At present, most of the domestic converter steelmaking plants are small and medium-sized converters with a furnace capacity of less than 100t. These converters cannot be equipped with gun equipment, and thus cannot realize intelligent steelmaking. For domestic large and medium-sized converter steelmaking plants, although th...
