Application Practice of the Condition Maintenance Technology of 200 tons Converter in Tanggang New District
The erosion mechanism of converter lining is analyzed,the current situation of converter lining erosion is proposed,and the dynamic control technology of slag splashing furnace protection,front surface maintenance technology,automatic slag hanging technology,and image recognition technology of converter bottom blow hole are introduced.Through the application of the above protection technology,the erosion rate of the converter surface is reduced from 0.49 mm/furnace in the upper furnace to 0.25 mm/furnace in the furnace age of 1000 furnace.The erosion rate of the bottom of the furnace decreased from 0.74 mm/furnace to 0.45 mm/furnace,and the age of the converter increased from 7 500 to 8 800,which provided a theoretical guide for extending the age of the converter.
