Quantification and refinement technology of blast furnace blow-in and sealing and its application
Based on the blast furnace material and heat balance combined with basic theory of ironmaking and its production requirement,the integrated computation model was established.The model was successfully applied in the production practice of blast furnace blow-in and sealing repeatedly with different volume,raw materials and fuels in Kungang Company.The practice results showed that the technology was easy to realize quantification and refinement in the important operations such as the blast furnace blow-in and sealing,which greatly shortened the time of reaching full production after blow-in or sealing and reduced the blow-in and sealing costs significantly.
