Titanium fine furnace protection clay plays the role of protecting the furnace wall in the iron mouth area, lowering the water temperature difference and sidewall temperature, reducing the blast furnace backloading, blocking the wind mouth, and ensuring the safety and stability of the blast furnace running smoothly. Compared with other titanium-containing slimes, the TiO2 content of Baoyi Refractories' titanium-containing furnace protection slime can be adjusted within the range of 4-15% according to the actual situation of the blast furnace, so that it has the functions of good performance of opening and blocking the mouth, long time of iron discharge, and effective suppression of the brick lining temperature in the mouth area, and so on.
