Hole-drilling iron-opening brick

The utility model discloses a borehole iron notch brick, consisting of not more than eleven bricks made of aluminum-carbon-silicon carbide material arranged on the iron and the brick in the center of the iron notch is provided with an opening for iron melt pouring. The utility model adopts large bricks, thus greatly reducing the number of bricks; and pre-drilled iron notch hole, thus reducing the gap between bricks and avoiding local fever and early damage of furnace lining as well as infiltration of iron slag into the furnace lining through brick gaps due to many brick gaps and gas leakage. The utility model has the advantages of good slag resistance, high thermal conductivity, good thermal stability and overall structural stability, thus effectively guaranteeing the tightness of the iron notch, plus less brick shapes and convenient installation. In addition, due to the adoption of aluminum-carbon-silicon carbide brick, the utility model solves the phenomenon of viscoid slag and iron and increases the alkali
