The particle size distribution is more uniform, and the overall refractory structure is made more dense, and its bulk density is significantly higher. It has a positive effect on resisting slag sharp intrusion. 'The iron outlet plugging of the present invention is a new type of refractory material for blast furnaces'. By the combination of the volume composition of the aggregate, the expanded material and the bonded material, and the selection of the raw materials, and the overall chemical composition of the aluminum oxide. 12 201236997 The weight percentage is 25wt%~45wt%, carbon cut and nitrogen cut plus the weight percentage of one and the other... one%, compared with the existing taphole:: has a faster and stable sintering rate, and good anti-fishing milling Invasiveness achieves the creative purpose of the present invention. However, the above is only the preferred embodiment of the present invention, and the scope of the present invention can be limited thereto, that is, the simple (four) effect change and modification according to the scope of the present invention and the description of the invention are the present invention. Within the scope of the patent. White [Simple description of the drawing] Fig. 1 is a schematic cross-sectional view showing the situation in which the plugging of the kiln is used to block the tap hole of the kiln in the blast furnace iron making operation.口13 201236997 3 ..........铁水4 ..........>4 [Main component symbol description] 1..........iron outlet Blocking mud 21 ......... blast furnace 22 ......... tapping port 14
