One of the convex ring 4 and the groove 6 is provided on the outer side surface of the hearth lining 1, and each of the convex ring 4 and the groove 6 is annular. The other one of bulge loop 4 and recess 6 is equipped with on resistant material layer 3's the inboard face, and bulge loop 4 cooperation is in recess 6, and the medial surface of resistant material layer 3 and the laminating of the lateral surface of hearth inside lining 1. The taphole frame 2 is arranged on the refractory layer 3.
Molten iron outflow channel 5 passes resistant material layer 3 and hearth lining 1, is equipped with the opening that leads to molten iron outflow channel 5 on the taphole frame 2, and the first opening of molten iron outflow channel 5 is located resistant material layer 3's outside side, and the second opening of molten iron outflow channel 5 is located hearth lining 1's medial surface, and wherein, each in recess 6 and the bulge loop 4 sets up around molten iron outflow channel 5.
One of the convex ring 4 and the groove 6 is arranged on the outer side surface of the hearth lining 1, and the other of the convex ring 4 and the groove 6 is arranged on the inner side surface of the refractory layer 3. That is, the outer side surface of the hearth lining 1 is provided with a convex ring 4, and the inner side surface of the refractory layer 3 is provided with a groove 6; or, the outer side surface of the hearth lining 1 is provided with a groove 6, the inner side surface of the refractory layer 3 is provided with a convex ring 4, and the convex ring 4 is matched in the groove 6.
According to the utility model discloses blast furnace tap hole is through being equipped with one in bulge loop 4 and recess 6 on the lateral surface of hearth lining 1, is equipped with the other in bulge loop 4 and the recess 6 on the medial surface of resistant material layer 3, and the cooperation of bulge loop 4 in recess 6. So that the binding surface of the refractory layer 3 and the hearth lining 1 (the inner side surface of the refractory layer 3 and the outer side surface of the hearth lining 1) is provided with a convex ring 4 and a groove 6 which are matched with each other. So that the joint surface (sealing surface) of the refractory layer 3 and the hearth lining 1 has a bent part (the joint surface of the refractory layer 3 and the hearth lining 1 forms a labyrinth structure).
When going out the molten iron, labyrinth prevents that coal gas from assaulting the binding face, the binding face of part of buckling (resistant material layer 3 and the labyrinth structure of the binding face formation of hearth lining 1) can block the coal gas and continue to assault the binding face of resistant material layer 3 and the depths of hearth lining 1 (keeping away from molten iron outflow channel 5), thereby make the part of buckling (the labyrinth structure that the binding face of resistant material layer 3 and hearth lining 1 formed) block the gap between resistant material layer 3 and the hearth lining 1 and continue the increase, prevent gas leakage, prevent that more molten irons from flowing into in the gap of resistant material layer 3 and the binding face department of hearth lining 1.
Each of the collar 4 and the groove 6 is ring-shaped, wherein each of the groove 6 and the collar 4 is provided around the molten iron outflow channel 5. So that the joint surfaces of the refractory layer 3 and the hearth lining 1 around the molten iron outflow passage 5 are both provided with bent portions (a labyrinth structure formed by the joint surfaces of the refractory layer 3 and the hearth lining 1). Thereby preventing any gap formed between the refractory layer 3 and the hearth lining 1 from continuously increasing.

Namely, the convex ring 4 can be better filled in the groove 6, and the gap between the convex ring 4 and the groove 6 is smaller, so that the impact of gas can be effectively blocked. Thereby preventing the gap between the refractory layer 3 and the hearth lining 1 from increasing, preventing the gas from leaking and preventing more molten iron from flowing into the gap between the refractory layer 3 and the hearth lining 1
In some embodiments, there are a plurality of grooves 6 and a plurality of collars 4. The plurality of grooves 6 are arranged around the molten iron outflow channel 5 centering on the molten iron outflow channel 5 so as to form concentric circles. A plurality of collars 4 are arranged around the molten iron outflow passage 5 centering on the molten iron outflow passage 5 so as to form concentric circles. The grooves 6 are matched with the convex rings 4 in a one-to-one correspondence manner, so that the bent parts (the labyrinth structure formed by the binding surfaces of the refractory layer 3 and the hearth lining 1) of a plurality of concentric circles are arranged around the molten iron outflow channel 5 by taking the molten iron outflow channel 5 as the center, the impact of coal gas is further blocked, and the increase of the gap between the refractory layer 3 and the hearth lining 1 is prevented.
As shown in fig. 1, in some embodiments, the hearth lining 1 is a carbon brick and the refractory layer 3 is a casting material. The castable is poured at the refractory layer 3, so that the inner side surface of the refractory layer 3 is attached to the outer side surface of the hearth lining 1, and a gap between the refractory layer 3 and the hearth lining 1 is reduced.
In some embodiments, the groove 6 has a groove width and a groove depth of greater than 5 mm. The convex surface width of the convex ring 4 and the length of the convex ring 4 are both larger than 5 mm. The matching surface of the groove 6 and the convex ring 4 is large, so that the pouring material can be completely filled in the groove 6, or the pouring material can be completely coated outside the convex ring 4, and gaps between the matching surface of the groove 6 and the convex ring 4 are reduced.
As shown in fig. 1, in some embodiments, the first opening of the molten iron outflow passage 5 is higher than the second opening of the molten iron outflow passage 5. Thereby making the molten iron in the blast furnace flow out from the molten iron outflow channel 5 and reducing the outflow of the iron slag.
The utility model also provides a blast furnace, the blast furnace includes foretell blast furnace taphole to make according to the utility model discloses a blast furnace has the gap increase that prevents between resistant material layer 3 and the hearth inside lining 1, prevents that coal gas from leaking and prevents more molten irons from flowing into the advantage in the gap between resistant material layer 3 and the hearth inside lining 1.
