Study On Operation Regulation Optimization Of Blast Furnace In Jiugang

Steel is one of the important metal materials and is widely used in various fields.One of the important signs of a country’s development is the degree of development of steel production.The upgrading of industrialization,automation and intelligence is an important indicator of the comprehensive strength of modern countries.The main indicator of whether the country is developed is the degree of industrial mechanization and automation.Labor productivity is one of the most important indicators for assessing the level of industrialization.A large amount of mechanical equipment is required to achieve high labor productivity.The steel industry provides the most basic materials for the manufacture of parts and machinery required for various industries,and belongs to the basic materials industry.Through the research on the development of blast furnace smelting at home and abroad and the impact of blast furnace smelting operation system on the technical and economic indicators of blast furnace,combined with the status quo and existing problems of slag blasting,air supply,charging and heat system in the blast furnace operation,Based on the production status of Jiugang blast furnace and a large number of detailed production data,Jiugang No.1 blast furnace and No.2 blast furnace are the main research objects,and the operation system of each period is compared and tested,and it is continuously optimized and practiced.Explored the various operating systems that are currently suitable for the Jiugang blast furnace.It includes a reasonable furnace material structure,a reasonable charging system,a reasonable slagging system,a reasonable air supply system,and a reasonable thermal system.Through comparative analysis and experiment,we continuously optimize and practice the rational operation system of Jiugang blast furnace to optimize the effect of blast furnace antegrade,the impact on product quality and the impact on major technical and economic indicators,so that the blast furnace can be put into the furnace.The coke ratio is significantly reduced,the product quality is significantly improved,and huge benefits have been achieved in blast furnace smelting.The best operating system must be combined with the concentrate level,equipment level,personnel quality and scientific management to create the best economic benefits.
