Background technology
The patent No. is 200920030724.5, patent is called square billet, rectangular bloom stopper bag fast sprue-replacing device, it is made up of brick cup, filling pipe end, the lower mouth of a river, filling pipe end and the lower mouth of a river are placed in inside brick cup, filling pipe end lower surface and upper surface, lower mouth of a river compact siro spinning technology, the lower mouth of a river is connected with quick change slide block, quick change upper end of slide block face and lower surface, lower mouth of a river compact siro spinning technology, and quick change slide block is connected with submersed nozzle. In use, filling pipe end and the lower mouth of a river fit together, and gap is inevitably left in centre, and molten steel has risk of leakage, affect the service life of the mouth of a river and brick cup, and of long duration can causing wears bag.
The patent No. is 201220008356.6, patent a kind of Integral nozzle brick cup by name, is formed by saving under joint, brick cup on brick cup, it is provided with the mouth of a river in joint under brick cup, saving on brick cup and save one-body molded under brick cup, whole brick cup sealing is good, and seepage impact use will not occur when molten steel is by the mouth of a river. But owing on brick cup, joint is cylinder, under brick cup, joint is cuboid, and one-body molded rear transition region intensity is likely to occur weak spot and undeclared inner lining material, and liner material is the key affecting Integral nozzle brick cup life-span and serviceability.
Utility model content
The purpose of this utility model is in that: there is gap for junction, the above-mentioned mouth of a river, and mouth of a river inwall plug-in mounting zirconium core holds caducous problem, it is provided that a kind of overall brick cup mouth of a river, make simple, be conducive to improving tundish safety, reduce air-breathing, prevent the rim of a bowl dross, improve the mouth of a river life-span.
In order to reach object above, the technical solution of the utility model is as follows: a kind of long-life entirety brick cup mouth of a river, including the brick cup body adopting high alumina graphite material, described brick cup body is embedded in tundish shell, it is characterized in that: described brick cup body interior is provided with the runner of up/down perforation, described runner upper end is provided with the flow control mouth with tundish inner space, lower end is provided with filling pipe end installation position, runner inner wall between described flow control mouth and filling pipe end is provided with the inner liner of aluminum zirconium carbonaceous material, inlays zirconium bowl in described flow control mouth. Flow control mouth place inlays zirconium bowl and is possible to prevent the rim of a bowl dross.Prior art improves the life-span frequently with the way of plug-in mounting zirconium core, but zirconium core is easy to fall off thus blocking the mouth of a river. This structure arranges inner liner in runner inner wall, compared to prior art, it is possible to avoid nozzle blocking, improves the corrosion resistance at the brick cup mouth of a river, thus increases the service life at the brick cup mouth of a river.
Further, described zirconium bowl is outside in round table-like, and inside has trumpet-shaped cavity, and the internal diameter of described cavity is from top to bottom gradually reduced. Trumpet-shaped cavity contributes to conflux molten steel, improves molten steel circulation efficiency.
Further, described inner liner and described zirconium bowl lower end closely touch; The internal diameter of described inner liner is equal to the internal diameter of described zirconium bowl lower end. Adopting this structure, inner liner and zirconium bowl junction smooth and seamless gap, molten steel will not seepage, it is to avoid occur wearing bag phenomenon.
Further, described brick cup body is cylindrical. Cylindrical brick cup body is more beneficial for one-shot forming compared to the square brick cup body of prior art, and improves brick cup mouth of a river intensity.
Further, described flow control mouth, runner, filling pipe end, slide gate nozzle are concentric. Each part centerline overlaps, it is simple to makes, and can improve molten steel circulation efficiency.
The advantage of this structure is: 1. zirconium bowl is inlayed at flow control mouth place, it is prevented that the rim of a bowl dross; 2. overall brick cup mouth of a river profile is cylinder, is conducive to one-shot forming, improves intensity; 3. overall brick cup mouth of a river inwall is provided with the inner liner that aluminum zirconium carbonaceous material is made, it is possible to improve the service life at mouth of a river corrosion resistance and the brick cup mouth of a river, solves by the high core problem to improve the life-span, it is to avoid in use procedure, zirconium core comes off and causes nozzle blocking.

Fig. 1 is one one kinds of long-life entirety brick cup gate structure schematic diagrams of this utility model embodiment;
Fig. 2 is that the overall brick cup mouth of a river coordinates figure with filling pipe end, slide gate nozzle installation.
In figure: 1-zirconium bowl, 2-brick cup body, 3-inner liner, 4-flow control mouth, 5-filling pipe end installation position, 6-runner, 7-filling pipe end, 8-tundish shell, 9-slide gate nozzle.
Detailed description of the invention
In order to be more fully understood that this utility model, below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
Embodiment one
Fig. 1 illustrates the first embodiment of the present utility model. As it is shown in figure 1, a kind of long-life entirety brick cup mouth of a river, including the brick cup body 2 adopting high alumina graphite material, brick cup body 2 is cylindrical, and its external diameter is 220mm. Cylindrical brick cup body is more beneficial for one-shot forming compared to the square brick cup body of prior art, and improves brick cup mouth of a river intensity. Brick cup body 2 is embedded in tundish shell 8. The internal runner 6 being provided with up/down perforation of brick cup body 2, runner 6 upper end is provided with the flow control mouth 4 with tundish inner space, and lower end is provided with filling pipe end installation position 5, and the lower internal diameter of filling pipe end installation position 5 is 100mm. Runner 6 inwall between flow control mouth 4 and filling pipe end 7 is provided with the inner liner 3 of aluminum zirconium carbonaceous material, and inner liner 3 is cylindrical, and its internal diameter is 29mm, and thickness is 14mm. Zirconium bowl 1 is inlayed in flow control mouth 4. Zirconium bowl 1 is outside in round table-like, and inside has trumpet-shaped cavity, and the internal diameter of cavity is from top to bottom gradually reduced. The height of zirconium bowl 1 is 80mm, and its upper end external diameter is 110mm, and its upper-end inner diameter is 90mm. Inner liner 3 and zirconium bowl 1 lower end closely touch;The internal diameter of inner liner 3 is equal to the internal diameter of zirconium bowl 1 lower end. Trumpet-shaped cavity contributes to conflux molten steel, improves molten steel circulation efficiency. Flow control mouth 4, runner 6, filling pipe end 7, slide gate nozzle 9 are concentric. Each part centerline overlaps, it is simple to makes, and can improve molten steel circulation efficiency.
Flow control mouth 4 place inlays zirconium bowl 1 and is possible to prevent the rim of a bowl dross. Prior art improves the life-span frequently with the way of plug-in mounting zirconium core, but zirconium core is easy to fall off thus blocking the mouth of a river. This structure arranges inner liner in runner inner wall, compared to prior art, it is possible to avoid nozzle blocking, improves the corrosion resistance at the brick cup mouth of a river, thus increases the service life at the brick cup mouth of a river.
In addition to the implementation, this utility model can also have other embodiments. All employings are equal to replacement or the technical scheme of equivalent transformation formation, all fall within the protection domain of this utility model requirement.
