Description
Technical field
The utility model relates to a kind of ladle pocket block structures, belong to metallurgy industry steelmaking equipment technical field.
Background technique
Ladle is the container that molten steel is contained in metallurgical industry, is made of steel shell, interior block refractory brick, molten steel is mounted on by bottom
Mouth of a river outflow on brick cup, casts.Steel ladle is used for steel mill, molten steel is accepted before open hearth, electric furnace or converter by Foundry Works,
Carry out pouring practice.
It is especially almost harsh to the requirement of non-metallic inclusion as quality requirement of the user to steel is higher and higher.It is general
The pouring type of logical ladle pocket block is to flow on ladle after molten steel enters brick cup inside by steel base brick circular aperture
It is poured in the mouth of a river, steel ladle pouring latter stage be easy to cause molten steel to form turbulent flow, and ladle slag is involved in molten steel and forms nonmetallic folder
Sundries.
Currently, the mode being usually taken is steel ladle pouring latter stage to stop being poured in advance, and ladle remainder molten steel, meeting in this way
The increase of steel-making cost is caused, therefore, how to improve steel ladle pouring mode, the non-metallic inclusion effectively reduced in molten steel is same
When reduce cost, become steel mill's problem in the urgent need to address.
Utility model content
The utility model aim is to provide a kind of ladle pocket block structure, can reduce the rapids of steel ladle pouring process formation
Stream improves Molten Steel Cleanliness, solves the problems, such as background technique.
The technical solution of the utility model is:
A kind of ladle pocket block structure, includes steel base brick, ladle upper nozzle and magnesia powder, and the steel base brick is side
Shape structure, the center of steel base brick, which is equipped with, pours steel hole, and the top for pouring steel hole is cylindrical hole, pours the lower part in steel hole as cone
Shape hole, the upper surface of steel base brick be equipped with the groove one, groove two, groove three and the groove four that pour steel hole and be connected to, on ladle
The mouth of a river is fixed in the bellmouth of steel base brick lower part, and magnesia powder is equipped between ladle upper nozzle and steel base brick.
The center line of groove one and groove three on the steel base brick upper surface is overlapped, the center of groove two and groove four
Line is overlapped.
The center line arranged crosswise of the center line of the groove one and groove three and groove two and groove four.
The groove one, groove two, groove three and groove four are U-type groove.
The internal diameter of the bellmouth bottom of the steel base brick lower part is greater than the internal diameter on top.
Using the utility model, during steel ladle pouring, molten steel passes through groove one, the groove on steel base brick upper surface
Two, groove three and groove four enter ladle upper nozzle by pouring steel hole from different directions, can effectively mitigate molten steel formation
Turbulent flow.
The beneficial effects of the utility model are: the turbulent flow of steel ladle pouring process formation can be reduced, ladle slag is greatly reduced
It is involved in the probability of molten steel, improves Molten Steel Cleanliness, while ladle residue molten steel can be greatly lowered again, cost is reduced and the energy is situated between
Matter consumption.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model steel base brick main view；
Fig. 3 is the utility model steel base brick top view；
In figure: steel base brick 1, groove 23, groove 34, groove 45, pours steel hole 6, ladle upper nozzle 7, magnesium at groove 1
Emery dust 8.
Specific embodiment
Below in conjunction with attached drawing, by example, the utility model is described in further detail.
Referring to attached drawing 1,2,3, a kind of ladle pocket block structure includes steel base brick 1, ladle upper nozzle 7 and magnesia powder
8, the steel base brick 1 is square structure, and the center of steel base brick 1, which is equipped with, pours steel hole 6, and the top for pouring steel hole 6 is
Cylindrical hole, the lower part for pouring steel hole 6 is bellmouth, and the upper surface of steel base brick 1 is equipped with and pours groove 1 that steel hole 6 is connected to, recessed
Slot 23, groove 34 and groove 45, ladle upper nozzle 7 are fixed in the bellmouth of 1 lower part of steel base brick, ladle upper nozzle 7 with
Magnesia powder 8 is equipped between steel base brick 1.
In the present embodiment, groove 1, groove 23, groove 34 and the groove 45 on 1 upper surface of steel base brick are U
The center line of type groove, groove 1 and groove 34 is overlapped, and the center line of groove 23 and groove 45 is overlapped, groove 1 and groove
34 center line and the center line arranged crosswise of groove 23 and groove 45, and the center by pouring steel hole 6.
Using the utility model and each 200 furnace of pour steel of conventional ladle pocket block, ladle stops casting and passes through ladle
The control of slag automatic control system.Steel inclusion rank, field trash disproportion and steel ladle pouring finish surplus steel amount data pair
Than being shown in Table one:
Table one: the utility model and conventional ladle pocket block are poured Contrast on effect data
Tracking result is shown, pours steel using the utility model, steel inclusion rank and field trash disproportion are more conventional
Steel base brick has clear improvement, and is poured the surplus steel amount of ladle and significantly reduces.
