Description
Technical field
The utility model relates to a kind of reductions to pour remaining steel pack lining structure, belong to metallurgy industry steelmaking equipment technology neck
Domain.
Background technique
In continuous casting production process, the molten steel in ladle flows into tundish, shape after crystallized device is cooling by slide gate nozzle
At slab, ladle molten steel pours surplus in steel pouring process, to the recovery rate of iron of continuous casting, and steel-making steel technology have it is very big
Influence.
Existing ladle bottom building method is horizontal masonry, in tapping since molten steel washes away for a long time, bottom of steel ladle
The area that is hit will appear pit, reduces ladle life, causes ladle circular flow in short supply, while casting the later period in continuous casting,
It has part molten steel to reside in the pit at packet bottom, causes ladle to remain steel, at the same time, molten steel is poured to the following molten steel of critical altitude
Whirlpool can be generated, casting process may generate slag, at this time to guarantee slab quality, will close the mouth of a river, guarantee by getting rid of steel
Molten Steel Cleanliness causes to remain steel in ladle.Above-mentioned two situations can all cause ladle to remain steel, and then influence continuous casting of metals and receive
Rate increases steel-making steel technology.
Utility model content
The utility model aim is to provide a kind of reduce and pours remaining steel pack lining structure, and steel is enabled in continuous casting process
Water pours surplus and substantially reduces, and improves the recovery rate of iron of continuous casting, solves the problems, such as background technique.
The technical solution of the utility model is:
Remaining steel pack lining structure is poured in a kind of reduction, comprising ladle, hanging axis, plane refractory brick, packet bottom permanent layer, the mouth of a river and
Inclined-plane refractory brick, hanging axis are fixed on the outside of ladle and the packet bottom close to ladle, and the packet bottom of ladle passes through castable pouring ladle bottom
Permanent layer wraps and builds plane refractory brick and inclined-plane refractory brick in the permanent layer of bottom, and the packet bottom of ladle is equipped with the mouth of a river, the mouth of a river position
Between hanging axis and the center of ladle, plane fire resisting brick masonry is at the mouth of a river close to the region of hanging axis, and inclined-plane fire resisting brick masonry is in water
Region of the mouth far from hanging axis.
The region of the plane fire resisting brick masonry is plane, and the region of inclined-plane fire resisting brick masonry is inclined tiltedly to the mouth of a river
Face.
Angle α between the inclined-plane refractory brick and plane refractory brick is 6-8 degree.
The density of the inclined-plane refractory brick is greater than the density of plane refractory brick.
Using the utility model, by the side of bottom of steel ladle using plane fire resisting brick masonry at plane, the other side is using tiltedly
Fire resisting brick masonry in face realizes that the mouth of a river and the drop at packet bottom can prevent to increase the thickness of impact zone packet bottom refractory brick at inclined-plane
Only packet bottom remains steel due to wrapping bottom caused by washing away erosion；Simultaneously because bottom of steel ladle part is built using slope, steel is occupied
Packet portion volume, molten steel amount under the same conditions, ladle steel liquid level be higher than common ladle, reach critical altitude when, can
Reduce the surplus steel generated under molten steel is poured to critical altitude by slag.
The beneficial effects of the utility model are: can effectively reduce erosion of the molten steel to packet bottom impact zone, packet bottom recess is avoided
Caused by remain steel；Simultaneously because bottom of steel ladle part is built using slope, molten steel amount under the same conditions, ladle molten steel face is high
Degree is higher than common ladle, when reaching critical altitude, can reduce the surplus steel generated under molten steel is poured to critical altitude by slag.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
In the figure, it is marked as ladle 1, hanging axis 2, plane refractory brick 3, packet bottom permanent layer 4, the mouth of a river 5, inclined-plane refractory brick 6.
Specific embodiment
Below in conjunction with attached drawing, by example, the utility model is described in further detail.
Referring to attached drawing 1, a kind of reduce pours remaining steel pack lining structure, includes ladle 1, hanging axis 2, plane refractory brick 3, packet bottom
Permanent layer 4, the mouth of a river 5 and inclined-plane refractory brick 6, hanging axis 2 are fixed on the outside of ladle 1 and the packet bottom close to ladle 1, the packet of ladle 1
Bottom wraps by castable pouring ladle bottom permanent layer 4 and builds plane refractory brick 3 and inclined-plane refractory brick 6 in bottom permanent layer 4, ladle 1
It wraps bottom and is equipped with the mouth of a river 5, between hanging axis 2 and the center of ladle 1, the masonry of plane refractory brick 3 is leaned at the mouth of a river 5 at the mouth of a river 5
The region of nearly hanging axis 2, inclined-plane refractory brick 6 are built in region of the mouth of a river 5 far from hanging axis 2.
Specific embodiment:
In the present embodiment, packet bottom permanent layer 4 is poured using castable, and packet bottom permanent layer 4 starts after building
Build working lining.Castable and refractory brick are all made of refractory material commonly used in the art, such as alumina spinelle refractory
Castable and magnesia carbon brick, the density of inclined-plane refractory brick 6 are greater than the density of plane refractory brick 3.
Referring to attached drawing 1, the mouth of a river 5 is to 2 direction region of hanging axis, i.e., the left area at the mouth of a river 5, uses plane fire resisting in schematic diagram
Brick 3 is built, and the right area at the mouth of a river 5 in the bottom other side, that is, schematic diagram is wrapped, using inclined-plane refractory brick 6 by highly successively carrying out
It builds, realizes the drop with the mouth of a river.
The region built using plane refractory brick 3, packet bottom are plane；The region built using inclined-plane refractory brick 6, packet
Bottom is inclined-plane, and the angle α of inclined-plane and horizontal plane is 6 ~ 8 °, and height can successively increase when masonry.Wrapping is molten steel impact zone in the middle part of bottom,
Packet bottom horizontal zone can be higher than by building height herein, while suitably increase the density of molten steel shock zone refractory brick, can be improved
Bottom of steel ladle impact resistance, to extend ladle service life.
Compared with the packet bottom that conventional planar is built, the utility model can reduce impact zone and generate surplus to the erosion at packet bottom
Steel, while the surplus steel generated under molten steel is poured to low critical altitude by slag can be reduced, and then improve continuous casting of metals recovery rate, drop
Low steel-making steel technology.
