Blast furnace furnace smoke and protection method using titanium-containing spectroscopy

摘要

The present invention relates to a method that can suppress and protect the erosion with the furnace smoke for the long life of the blast furnace, and more specifically through a tuyere located in the upper portion 30 ~ 40 ° from the temperature rise portion of the thermocouple installed in the furnace furnace lead furnace. The present invention relates to a blast furnace furnace smoke and a protection method using a TiO ₂ -containing spectroscopy, characterized in that the TiO ₂ -containing spectroscopy containing a large amount of TiO ₂ is blown to form a Ti compound at the erosion site.;According to the present invention as described above, it is possible to selectively inject the TiO ₂ component-containing spectroscopy to the erosion furnace blast furnace erosion site, and to form a Ti compound in a short time to protect the furnace duct provides a great effect on the life of the blast furnace.
