Description
Technical field
The utility model relates to the ladles that a kind of working lining uses four spiral brick-building arts, belong to the technology neck of ladle masonry
Domain.
Background technique
Ladle refers generally to steel ladle, and the container of Sheng Gangshui is made of a steel, interior block refractory brick, and molten steel is flowed out by the mouth of bottom,
It casts.Cylinder-packing is magnesia carbon brick or magnesite-chrome brick, high-alumina brick, zirconium chrome brick.Steel ladle for steel mill, Foundry Works open hearth,
Molten steel is accepted before electric furnace or converter, carries out pouring practice.Structure type has rod type and two kinds of slide gate nozzle formula.Using ladle
In technology, ladle is one of melted steel container the most used in process for making.Due to the erosion of molten steel washed away with liquid slag,
Ladle lining fireproof material is easy to corrode, therefore ladle lining fireproof material is a ton Main way for steel refractory consumption, improves
The service life of refractory material in ladle is energy-saving one of the main path of steel mill, so improving the material of resistance to material in ladle
It is the project that engineer studies always with brick-building art.In ladle casting process, since the temperature of molten steel is excessively high, ladle working
Directly and steel contacts, molten steel can corrode steel ladle working layer brick to the brick of layer, and the part that refractory brick is etched, and will become and be unfavorable for
The objectionable impurities of purification of molten steel.So in order to solve this problem, improving brick-building art becomes the top priority of numerous steel mills.
It is built currently, ladle liner refractory brickwork generallys use successively annular block method, although not needing using special shaped brick,
Successively annular block method must close the weak link that tweel block is masonry using tweel block is closed when every layer of brick closes up, and brickwork joint is difficult to control；
Some are able to maintain the gap between brick and brick unanimously, build convenient and ensure that tank body
Globality, effectively avoid the infiltration steel phenomenon between brickwork joint, since double helix rises before and after slope there are break, built in up spiral
When building, break nearby inevitably generates exceeded brickwork joint；The ratio bottom that impact zone is all only built in existing ladle structure
Workspace is more slightly higher, can still caused biggish destruction to the material of impact zone by molten steel impact type, form impurity and pollute steel
The quality of water.

Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
As shown, a kind of working lining uses the ladle of four spiral brick-building arts, including ladle shell 1, air brick 6 and water
Mouthful brick 7 is equipped with permanent layer 2 on 1 inner wall of ladle shell, packet bottom working lining 4 is equipped in the bottom interior wall of permanent layer 2, permanently
It is equipped with containment wall working lining 3 on the side wall of layer 2, wraps and is provided with packet bottom impact zone 5 in the middle part of bottom working lining 4, the two of packet bottom impact zone 5
Side is respectively arranged with air brick 6 and nozzle brick 7, water outlet 8 is offered on nozzle brick 7, the first floor 10 of containment wall working lining 3 is by four
A slope layer 9 joins end to end to form four helical structures, and playing slope layer 9 is built by brick 11 level in slope several, plays slope brick
The prototype of 11 ontologies be straight brick, increase the gradient on the basis of straight brick, and the gradient is consistent, wrap bottom impact zone 5 top to
Shape camber protrusion, wraps and is evenly arranged with convex block 12 at the top of the impact zone of bottom, so that the molten steel poured into forms whirlpool in ladle
Stream reduces destruction of the molten steel to packet bottom impact zone 5.
Double sections that the first floor 10 enable play slope layer 9 and build；Rise slope layer 9 be by slope brick 11 several along the gradient be incremented by direction according to
It is secondary to be formed by connecting, so that the gradient for playing slope layer 9 is consistent；The cross section for playing convex position and packet bottom of the packet bottom impact zone 5
The top surface of working lining 4 is in same level；Permanent layer 2, which is that high alumina castable is integrated poured, to be formed；Containment wall working lining 3 and institute
It states packet bottom working lining 4 to be built by magnesia carbon brick, the thermal insulation property of high alumina castable is utilized, so that liquid steel temperature will not be fast
Prompt drop temperature avoids skin temperature excessively high or even rubescent, energy saving；On the other hand the erosion-resisting characteristics of magnesia carbon brick is also utilized,
Also reduce the cost of ladle；By the center at 5 top of packet bottom impact zone, edge is extended convex block 12 around.
Utility model works principle: as shown in Figs. 1-5, including rise slope brick 11 starting altitude C1, terminal height C2 and
Play 11 difference in height B of slope brick, play slope layer 9 in ladle wall working lining 3, rise 11 starting altitude C1 of slope brick in containment wall working lining 3
Initial position, rise slope brick 11 terminal height C2 rise slope layer 9 a final position, rise slope brick 11 difference in height B at adjacent
The difference in height position of slope brick 11；The prototype that containment wall working lining 3 plays slope brick 11 is straight brick, increases difference in height on the basis of straight brick
B plays slope layer 9 and is located in steel ladle working layer, and starting altitude C1 can be adjusted according to ladle pouch-type, and terminal height C2 can be according to reality
Border needs to design, and plays slope layer 9 and joins end to end to form four helical structures, redesign plays slope brick 11 accordingly, the slope for building spiral
Degree is consistent, avoids exceeded brickwork joint to completely eliminate, and avoids every laminated door in building process, and increase ladle uses the longevity
Life reduces the time for building ladle, and then reduces the cost of ladle；The gradient, the width and thickness for playing slope brick 11 can be according to steel
Packet actual needs adjust, rise slope brick 11 first brick can height according to actual needs increase or decrease；Ladle is poured into molten steel
When, impact of the molten steel to packet bottom impact zone 5,5 top of packet bottom impact zone can be reduced by wrapping the arc convex being arranged at the top of bottom impact zone 5
The convex block being uniformly arranged can make molten steel form vortex in ladle, can offset molten steel and impact to a part of packet bottom impact zone 5
Power to reduce destruction of the molten steel to packet bottom impact zone 5, and then reduces impurity content, guarantees the purity of molten steel；
The process of producing product and common steel wrapping machine pressure brick production method are consistent, will not extra band to carry out any production tired
Difficulty will not bring the increase of production cost；The production is simple, saves material, and easy for construction, using effect is ideal, fits
Close batch production.
The above are the preferable embodiment of the utility model, the utility model those skilled in the art can also be to upper
It states embodiment to change and modify, therefore, the utility model is not limited to above-mentioned specific embodiment, all abilities
