Abstract
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.
Description
Technical field
The utility model belongs to the blast-furnace smelting field, relates in particular at the bottom of a kind of State of Blast Furnace with novel fully-closed lead discharging groove.
Background technology
During the more iron ore of blast-furnace smelting lead tolerance, have low-melting lead solution to generate at furnace bottom, if the lead discharging groove is not set at the bottom of the State of Blast Furnace, lead solution just can't be discharged, and is easy at furnace bottom along charcoal piece slit furnace bottom charcoal piece jack-up destruction furnace bottom furnace lining structure.The structure of past lead discharging groove is at furnace bottom charcoal piece surface fluting, places the clay matter lead discharging groove brick of 3 combinations in groove, and wherein 2 dock into groove through processing, and another piece is a cover block.This complex structure, single brick processing quantity is many, difficulty of construction is big, the time is long, and it is poor to build many stopping propertys of brickwork joint by laying bricks or stones, lead solution is easy to ooze out from brickwork joint, destroy furnace bottom brick fuel interior tissue, influence whole furnace lining structure, add the water-cooled of lead outlet cooling stave, cause lead solution frozen plug lead outlet.
The utility model content
The purpose of this utility model provides at the bottom of a kind of State of Blast Furnace with novel fully-closed lead discharging groove groove, by the improvement to lead discharging groove list brick shape, reduces the investment cost of material, prolongs furnace bottom work-ing life.
In order to achieve the above object by the following technical solutions: at the bottom of a kind of State of Blast Furnace with novel fully-closed lead discharging groove groove, by general brick, threeway brick, four-way brick and end brick build in furnace bottom charcoal piece groove and be filled with the plain ramming mass of charcoal at periphery constitute, lead outlet place at the lead discharging groove is provided with insulating brick, described general brick is the middle brick that through hole is set, the threeway brick is the brick that the center is provided with the T-shaped hole, the four-way brick is the brick that the center is provided with cross bore, and the end brick is the brick that an end is provided with blind hole.
The aperture of described through hole, T-shaped hole, cross bore and blind hole equates.
The two ends of described general brick, threeway brick and four-way brick are respectively arranged with projection and the groove that matches.The blind hole end of described end brick is provided with projection.
The projection at described general brick, threeway brick and four-way brick two ends and the diameter of groove are all greater than the aperture of through hole, T-shaped hole, cross bore and blind hole; The projection of end brick and the groove of general brick match.
The utility model is by the improvement to lead discharging groove list brick shape, make the lead discharging groove simple and practical, reduce the investment cost of material, easy construction, shorten the time of building stove, inlay mutually between brick and the brick and build by laying bricks or stones, improved stability of structure, and lead discharging groove area occupied is little, little to the heat transfer influence of furnace bottom, and lead solution is discharged out of the furnace more smoothly by the lead discharging groove, minimizing is to the destruction of furnace lining structure, prolongs furnace bottom work-ing life, and novel fully-closed lead discharging groove is simple in structure, the lead discharging groove is to be formed by a brick boring, is the hermetically sealed structure of closing.

Embodiment
As at the bottom of kind of the State of Blast Furnace of Fig. 1～5 one with novel fully-closed lead discharging groove groove, build by laying bricks or stones in the groove of furnace bottom charcoal piece 6 and be filled with the plain ramming mass 7 of charcoal by general brick 1, threeway brick 2, four-way brick 3 and end brick 4 and constitute at periphery, lead outlet place at the lead discharging groove is provided with insulating brick 5, shown in Fig. 6,7, general brick 1 is the middle brick that through hole 8 is set, and the two ends of brick are respectively arranged with projection 9 and the groove 10 that matches; Shown in Fig. 8,9, threeway brick 2 is provided with the brick in T-shaped hole 11 for the center, and the two ends of brick are respectively arranged with projection 9 ' and the groove 10 ' that matches; Shown in Figure 10,11, four-way brick 3 is provided with the brick of cross bore 12 for the center, and the two ends of brick are respectively arranged with the projection 9 that matches " and groove 10 "; Shown in Figure 12,13, end brick 4 is the brick that an end is provided with blind hole 13, and the blind hole end of brick is provided with projection 9 " '.Wherein the aperture of through hole 8, T-shaped hole 11, cross bore 12 and blind hole 13 equates; The projection at described general brick 1, threeway brick 2, four-way brick 3 and end brick 4 two ends and the diameter of groove are all greater than the aperture of through hole, T-shaped hole, cross bore and blind hole.
During use, general brick, the threeway brick, the four-way brick is combined into the lead discharging groove by using the position difference to build by laying bricks or stones respectively in furnace bottom charcoal piece groove, and use end brick sealing of hole, straight line is connected between brick and the brick, the front end boss inserts groove position, back, block is stung at the brick two ends mutually, improved the stopping property of lead discharging groove, at general brick, the threeway brick, the periphery of four-way brick and end brick is filled the plain ramming mass of charcoal, lead discharging groove insulating brick is set going out the lead bath mouth, builds by laying bricks or stones with layer, in case cooling stave place temperature is low, lead solution solidifies row does not go out, and adopts the insulation measure in plumbous liquid exit, has solved because the low problem that causes the outlet of lead solution frozen plug of cooling stave temperature.
