description The utility model discloses a novel fully-closed lead discharge tank for a blast-furnace bottom. The lead discharge tank is constructed by laying universal bricks, three-way bricks, four-way bricks and end bricks in a furnace bottom carbon block groove and filling a carbon ramming material at the periphery, wherein heat preservation bricks are arranged at a lead outlet of the lead discharge tank; through holes are formed in the middle of the universal bricks; T-shaped holes are formed in the center of the three-way bricks; crossed holes are formed in the center of the four-way bricks; and blind holes are formed at one end of the end bricks. By improving the shape of a single brick of the lead discharge tank, the lead discharge tank has a simple and practical structure, reduces the investment cost of the material, is convenient to construct and shortens the brick laying time.
