What are the refractory materials used in the blast furnace casting yard?

Due to the different scales of domestic blast furnace tapping yards, the refractory materials used in blast furnace tapping yards are also quite different. The blast furnace tapping plant uses refractory materials to make a simple analysis. Generally, small blast furnaces below 1000m³ use lower-priced ramming materials and lower-strength ramming materials. Large blast furnaces above 2000m³ generally use good castables and high-cost gun mud. In the medium-sized blast furnace, the surplus is between the two, and there is a tendency to approach the refractory materials used in the large blast furnace casting yard.
