China Anhydrous/Waterless Taphole Clay Used for Large Size Blast Furnace, Find details about China Taphole Clay, Taphole Anhydrous Refractory Clay from Anhydrous/Waterless Taphole Clay Used for Large Size Blast Furnace
Product Description:
Taphole clay is a refractory material used to seal the taphole. It can be divided into two categories: water clay and water-free clay. The former is used in small and medium-sized blast furnaces with low top pressure and low intensified smelting, and the latter It is used in large and medium-sized blast furnaces with high top pressure and high degree of intensified smelting. Among them, Taphole clay uses clay powder, clay refractory brick crushing particles, and coke powder as the main raw materials, and appropriately adds asphalt, high alumina bauxite, silicon carbide, etc., and uses water as a binding agent. Commonly used waterless Taphole clay raw materials are generally corundum, high alumina bauxite, silicon carbide, clay and coke powder.
In order to improve the performance of taphole clay and increase its strength and corrosion resistance, raw materials such as metallic silicon, metallic aluminum, sericite powder, and ferrosilicon nitride have been used. The addition of various fine powder and ultrafine powder raw materials has further increased its density and sintering performance. Waterless Taphole clay usually uses tar, dianthracene oil, and resin as binders.
