Practice On Longevous Production Of Tongsteel No.7 BF

This paper expounds the Tonghua iron and steel co., LTD no. 7 blast furnace cylinder masonry structure and the present state of erosion, high heat load is analyzed regional department of bosh, belly and furnace body using copper cooling wall structure and characteristics. To ensure that no. 7 blast furnace blast furnace high efficiency and long life goal truly, maximizing the interests for the company, for reasonable distribution of gas flow and standardized operation problems by using mathematical statistics methods to analyze it, data and formulate reasonable operation parameter optimization system. Through a comprehensive strengthening monitoring, setting up the management system of the longevity, of hearth erosion dynamic trend, make comprehensive analysis and judgment. By taking effective measures to control the temperature of the toroidal carbon brick, such as the reduction of blast furnace smelting intensity, tuyere feeding titanium wire, titanium ore furnace protection and forcibly plugging tuyere and so on, to implement the bf longevity.
