DEVELOPMENT OF A DECISION SUPPORT SYSTEM FOR CONTROLLING THE DISTRIBUTION OF BLAST PARAMETERS OVER BLAST FURNACE TUYERES<\/h2>\n\n\n\n

Abstract.<\/strong> The article describes the problem of automated control of the quantitative distribution of the blast on the air tuyeres of a blast furnace (BF), which has been studied for many years and is still not fully resolved and relevant, since the uneven distribution of the blast significantly affects the gas distribution and thermal state throughout the volume of the BF. The results of the effectiveness of the application of the method of controlling the distribution of the blast parameters on the air tuyeres when manually measuring the thermal loads on the flanges of the suspended knees of the tuyere devices BF-1M and BF-12 of PrJSC “Kamet-steel” in 2018-2020 are shown. The methodological and information principles of the decision support system (DSS) for controlling the distribution of the blast parameters on the tuyeres of the BF, which has been developed in recent years at the Iron and Steel Institute, are presented. The creation of the DSS consists of the following stages: using information from modern automated control tools with the establishment of statistical dependencies of this information with blast smelting indicators; creation of a representative database containing various BF operating modes with corresponding technical and economic indicators of BF smelting, charging mode parameters and information on control means; development of a block of recommendations. DSS should include: visualization of primary information on the distribution of temperature differences and cooling water consumption around the circumference of the BF; visualization of calculated information on the distribution of the actual RAFT (raceway adiabatic flame temperature), consumption and blast speed, and the geometry of the raceway zone around the circumference of the BF; a block for generating recommendations on adjusting the consumption of fuel additives on individual tuyeres to ensure the required circumferential distribution of the RAFT; signaling on the presence of the so-called “slagging” of tuyeres; recommendations on changing the diameters of air tuyeres. DSS for controlling the circumferential distribution of blast parameters in a BF should also provide for the development of methods and criteria that allow for the synergistic interaction of the functioning of various DSSs installed on the BF. The article first shows the influence of the unevenness of the circumferential distribution of the thermal state of the lower zone of the BF, according to the distribution of the RAFT along the air tuyeres, on the development of the central gas distribution of the upper zone and the channel course of the BF, according to the readings of the means of controlling the temperatures of the gas flow above the charge surface. The dependences of the temperature indicators of the gas flow above the charge surface on the root mean square deviation of the RAFT along the circumference of the BF are obtained. The article indicates that an important stage in the development of the DSS is the testing of both its individual components and a set of recommendations for controlling BF smelting in real production conditions.<\/p>\n\n\n\n
