Description
Technical field
This utility model increases the extra furnace dephosphorization molten iron packaging of ladle internal volume in being related to a kind of vanadium-bearing hot metal pretreatment
Put, belong to hot metal in steelmaking bag equipment technical field.
Background technology
When smelting containing valuable vanadium resource molten iron, typically using vanadium extraction-steel-making duplex technique, due to vanadium titano-magnetite
Molten iron phosphorus content it is higher between 0.150%-0.225%, low-phosphorous kind requires phosphorus content≤0.012%, thus results in converter
Slag charge, iron and steel stock, alloy material etc. consume high, implement the outer semi-steel dephosphorizing pretreatment of stove significant.120 tons of smelting devices are adopted
With the outer semi-steel dephosphorizing pretreatment of stove, set up on vanadium extraction from hot metal Process ba- sis, the content of silicon be vestige in 0.01%-0.03%, half
Steel temperature is advantage that dephosphorizing pretreatment creates high alkalinity, low temperature, that is, has saved de- between 1320-1380 DEG C
Phosphorus agent passive lime powder consumption, improves semi-steel dephosphorizing rate again, but brings following problem using common ladle：
1st, when ladle headroom 1500mm requirements above is met, splash during semi-steel dephosphorizing pretreatment is effectively controlled,
Charge weight is unsatisfactory for making steel charge weight requirement, must be blended into molten iron again, affect rhythm of production but in 90-100 tons/stove；
2nd, when charge weight meets 135 ± 3 tons/stove of steel-making to be required, between 400-600mm, half steel takes off ladle headroom
During phosphorus pretreatment, splash is serious, spills that ferrum is more and flue dust is larger；
3rd, such as increase ladle containment wall height, and mismatch with dephosphorization equipment, the suspension hook spacing of overhead traveling crane handling ladle is
Fixed, semi-steel dephosphorizing pre-treatment job is restricted.
If can solve the problem that the problems referred to above, semi-steel dephosphorizing expulsion events will be substantially improved, ferrum and flue dust are spilt in control, it is to avoid again
It is secondary to be blended into molten iron, it is smoothed out semi-steel dephosphorizing pretreatment, rhythm of production is guaranteed.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of extra furnace dephosphorization molten iron packaging of increase bag internal volume
Put, this molten iron bag apparatus can make ladle both meet dephosphorization Clearance requirement, converter charge weight requirement can be met again, reached de-
Phosphorus injection process is steady, and charge weight is stable, the significant purpose of dephosphorization effect, is that the smelting of low-phosphorous kind creates good conditions.
Solve above-mentioned technical problem technical scheme be：
It is a kind of increase bag internal volume extra furnace dephosphorization molten iron bag apparatus, it include ladle it is indentured, bag bottom, bag mouth, hanging axis,
Gudgeon, gudgeon are arranged symmetrically in the left and right sides of ladle middle and upper part, and two bag mouths are respectively positioned at both sides before and after ladle
In the middle of upper end, hanging axis is located in the middle of the lower end of the rear side of ladle, and its improvements is to be with two gudgeon vertical center lines
Indentured straight section connector is increased before and after marginal ladle between two parts, indentured straight section connector is rectangle, is wrapped
The upper end of body straight section connector is flushed with the indentured upper end of ladle, and the lower end of indentured straight section connector is connected with bag bottom, indentured
The both sides of straight section connector respectively with gudgeon vertical center line be marginal ladle before and after two-part ladle bag
Body is connected.
The extra furnace dephosphorization molten iron bag apparatus of above-mentioned increase bag internal volume, the indentured straight section that the ladle left and right sides increases
Connector is symmetry equivalent, and the width of two indentured straight section connectors is 200-400mm.
The beneficial effects of the utility model are：
Ladle height of the present utility model keeps constant with gudgeon spacing, with two gudgeon vertical center lines as marginal
Indentured straight section connector be increased between two parts before and after ladle, indentured straight section connector increases the bag content of ladle
Product, both without transforming the equipment such as overhead traveling crane suspension hook size and hired car base, can guarantee that dephosphorization headroom and converter charge weight requirement again,
Semi-steel dephosphorizing expulsion events are substantially improved, ferrum and flue dust are spilt in control, it is to avoid be blended into molten iron again, reach dephosphorization injection process and put down
Surely, charge weight is stable, the significant purpose of dephosphorization effect, is steady production rhythm, reduces lime consumption cost, smelts low-phosphorous kind
Favourable conditions are created, is smoothed out semi-steel dephosphorizing pretreatment, rhythm of production is guaranteed.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, labelling is as follows：Ladle is indentured 1, indentured straight section connector 2, bag bottom 3, bag mouth 4, hanging axis 5, gudgeon 6.
Specific embodiment
This utility model is by ladle is indentured 1, indentured straight section connector 2, bag bottom 3, bag mouth 4, hanging axis 5, gudgeon 6 are constituted.
Show in figure, gudgeon 6 is arranged symmetrically in the left and right sides of ladle middle and upper part, two bag mouths 4 are located at molten iron respectively
Before and after bag in the middle of the upper end of both sides, hanging axis 6 is located in the middle of the lower end of the rear side of ladle, with two 6 vertical centres of gudgeon
Line be marginal ladle before and after be welded with indentured straight section connector 2 between two parts, compared with existing ladle
Increase the volume in bag.
Show in figure, indentured straight section connector 2 is rectangle, on the upper end of indentured straight section connector 2 and ladle indentured 1
End flushes, and the lower end of indentured straight section connector 2 is connected with bag bottom 3, the both sides of indentured straight section connector 2 respectively with gudgeon 6
Vertical center line is that the two-part ladle indentured 1 in front and back of marginal ladle is connected, and the involucrum of whole ladle is horizontal
Rectangular in cross-section and two semicircle assemblys.
Show in figure, the indentured straight section connector 2 that the ladle left and right sides increases is symmetry equivalent, two indentured straight section connections
The width of part 2 is 200-400mm.
Show in figure, ladle indentured 1 is welded together with indentured straight section connector 2, the height of indentured straight section connector 2
It is identical with indentured, play a part of to increase bag internal volume.In other parts, hanging axis 5 is used to incline ladle, past by bag mouth 4
Iron making in stove, gudgeon 6 are arranged symmetrically in the left and right sides of ladle middle and upper part, and spacing keeps constant, moves molten iron for overhead traveling crane
Bag.
As ladle increased the width of indentured straight section connector 2, bag internal volume is increased, when molten iron is packaged into molten iron
During 135 ± 3 tons/bag, headroom >=1500mm in bag had both met dephosphorization Clearance requirement, and had met converter charge weight requirement again, be low-phosphorous
The smelting of kind creates good conditions.
