Abstract
The utility model discloses a steel ladle bottom bleeder vent, including building the air brick that has the bleeder vent on the steel ladle bottom involucrum by laying bricks or stones, the welding has the wedge -shaped cushion piece on the involucrum of air brick below, the middle part of wedge -shaped cushion piece seted up with the corresponding through -hole of air brick bleeder vent. The sectional form of wedge -shaped cushion piece is the right angled triangle structure, with the inclination an on the slope that the air brick contacted is 10 3, and what make the air brick blows the angle towards the ladle center. The utility model has the advantages of addding the wedge -shaped cushion piece in the below of air brick, making the gaseous angle of bloing in in the ladle change, the molten steel spray that the stirring air current was dug evenly erodees to around the ladle, has reduced local the deteriorating fast of steel ladle lining, reaches steel ladle lining and erodees the equilibrium, and it is even to deteriorate, and the ladle bulk life time can prolong, has reduced steel ladle lining refractory material's consumption.
Description
Technical field
This utility model is related to ladle, especially relates to a kind of ladle bottom air-vent.
Background technology
Ladle bottom is typically fitted with the air brick with air-vent, and effect is that gases at high pressure blow into steel by air-vent
Bag is internal, molten steel is stirred, so that liquid steel temperature in ladle is evenly distributed, and adjustment molten steel is to optimal cast temperature；Lead to simultaneously
Cross stirring, also can make the distributed components in molten steel, product quality is stable, promote inclusion floating to bring in slag, meet
Purity requirements to molten steel.
According to the needs of ladle real work, bottom air brick is not mounted within the center of ladle bottom, but peace
It is installed adjacent to ladle side-walls.Wash away in the molten steel spray rolling that in the molten steel Argon whipping process in ladle, air-flow blows afloat
In the sidewall refractory material liner body of air brick, causing to be washed position erosion seriously (as shown in Figure 1), away from air brick
Side wall liner body deteriorate relatively light, ladle liner can not synchronously deteriorate.The liner body of local damage determines the use longevity of ladle liner
Life, in order to ensure production safety, the residual lining of ladle can be removed simultaneously, so will result in the significant wastage of inner lining material, more sternly
Weight is if to the not careful of local corrosion observation it is also possible to cause the substantial equipment that molten steel burns ladle to damage and personnel's wound
Die accident.
Content of the invention
The purpose of this utility model is to provide a kind of can make ladle side wall deteriorate the ladle bottom air-vent keeping synchronous.
For achieving the above object, this utility model can take following technical proposals:
Ladle bottom air-vent described in the utility model, carries the saturating of air-vent including building by laying bricks or stones on ladle bottom involucrum
Gas brick, the involucrum below described air brick is welded with correcting wedge, and the middle part of described correcting wedge offers is breathed freely with described
The corresponding through hole of brick air-vent.
The rectangular triangular structure of section configuration of described correcting wedge, the inclination on the slope contacting with described air brick
Angle a is 10 ± 3 °, and the air blowing angle making air brick is towards ladle center.
The utility model has the advantage of setting up correcting wedge in the lower section of air brick, make the gas angle being blown in ladle
Change, the molten steel spray that stirring air-flow is dug uniformly washes away to around ladle, decreases the quick erosion of ladle liner local
Damage, reach ladle liner and wash away equilibrium, deteriorate uniformly, ladle bulk life time is extended, and reduces ladle lining fireproof material
Consumption.
Brief description
Fig. 1 is the structural representation of existing ladle bottom air-vent.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the structural representation of correcting wedge in Fig. 2.
Fig. 4 is the top view of Fig. 3.
Specific embodiment
As shown in Figure 2,3, 4, ladle bottom air-vent described in the utility model, including building by laying bricks or stones in ladle bottom involucrum 1
The upper air brick 2 carrying air-vent, is welded with correcting wedge 3, the middle part of correcting wedge 3 is opened on the involucrum 1 below air brick 2
It is provided with the through hole 4 corresponding with air brick air-vent；The rectangular triangular structure of section configuration of correcting wedge 3, with air brick 2
The angle of inclination a on the slope contacting is 10 ± 3 ° (concrete angle of inclination suitably can be adjusted according to ladle structure), makes
The air blowing angle of gas brick 2 is towards ladle center.
Correcting wedge 3, using the steel with ladle involucrum phase same material, is directly welded on ladle bottom involucrum 1, both
Form one, be not in the loosening phenomenon that drops, air brick 2 can be born, Ladle Bottom is lined with and accepts the static pressure after molten steel.
When ladle bottom Argon stirring molten steel, external high pressure gas is blown in ladle from the air-vent of air brick 2, gas
The molten steel spray that stream is dug uniformly washes away to the surrounding of ladle, ladle side wall liner 5 is formed with uniform erosion, extends ladle
Overall service life, reduces the loss of lining material in the ladle.
