Description
Technical field
The utility model relates to the protective casting devices between a kind of slide plate for steel ladle, belong to metallurgy industry steelmaking equipment
Technical field.
Background technique
Protective casting is to completely cut off air and steel contacts.After oxygen and steel contacts in air, alloy member is reduced
The rate of recovery of element especially aluminium, the product of secondary oxidation of steel is also the main source of Large Inclusions.In addition, in air
Nitrogen enters molten steel, increases the crack sensitivity of slab, and causes the blue shortness phenomenon of steel.Molten steel is contacted with air and is brought
Many hazards need to carry out the protective casting of links to guarantee product quality.
Currently, the molten steel from ladle to tundish generallys use sliding equipment and comes coutroi velocity and switch in metallurgy industry.
Have upper slide and lower skateboard in sliding equipment, by the sliding of lower skateboard change upper lower skateboard two cross the relative position in steel hole come
It realizes and adjusts molten steel flow speed and switch.Due to upper and lower slide plate require to must be able to when work it is opposite slide, all upper and lower slide plates it
Between there is gap, may exist the gap 0.5mm between the upper and lower slide plate of matching requirements.In actual use, by bad working environments and ring
The influence in border, gap is unstable between upper and lower slide plate, and there is widened possibility in gap.In molten steel casting process, molten steel high speed beam
Certain negative pressure can be generated at gap between upper and lower slide plate, cause external air to be drawn into molten steel from slide plate gap, no
The requirement of protective casting can be reached.
Utility model content
The utility model aim is to provide the protective casting device between a kind of slide plate for steel ladle, can be avoided external sky
Gas is drawn into molten steel from slide plate gap, is reached the requirement of protective casting, is solved the problems, such as background technique.
The technical solution of the utility model is:
A kind of protective casting device between the slide plate for steel ladle, comprising pocket block, filling pipe end, cross steel hole, upper slide,
Lower skateboard, collector nozzle, argon blowing hole and groove, filling pipe end are fixed in pocket block, and filling pipe end is connected with collector nozzle, filling pipe end
It is equipped with mutually matched upper slide and lower skateboard between collector nozzle, is set respectively on filling pipe end, upper slide, lower skateboard and collector nozzle
There is mutually matched steel hole excessively, a circle groove, the groove are equipped in the plate face for the upper slide that upper slide is contacted with lower skateboard
It is connect by argon blowing hole with argon gas pipeline.
A circle groove in the upper slide plate face crosses steel hole arrangement on upper slide, and be integrally square structure.
The cross section of groove in the upper slide plate face is semicircle.
The filling pipe end is fixed on middle packet bottom by pocket block.
Using the utility model, argon gas is provided for the groove on upper slide by argon blowing hole, is deposited in upper slide and lower skateboard
In the case where gap, protective casting is may be implemented in the argon gas in groove, avoids the sucking of air, and effect is actively significant.
It is drawn into molten steel, reaches from slide plate gap the beneficial effects of the utility model are: can be avoided outside air
The requirement of protective casting.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the groove structure schematic diagram on the utility model upper slide；
Fig. 3 is the utility model upper slide and diagrammatic cross-section when lower skateboard fully opens；
Fig. 4 is the utility model upper slide and diagrammatic cross-section when lower skateboard completely closes.
In figure: pocket block 1, crosses steel hole 3, upper slide 4, lower skateboard 5, collector nozzle 6, argon blowing hole 7, groove 8 at filling pipe end 2.
Specific embodiment
Below in conjunction with attached drawing, by example, the utility model is described in further detail.
Referring to attached drawing 1-4, a kind of protective casting device between the slide plate for steel ladle, comprising pocket block 1, filling pipe end 2,
Steel hole 3, upper slide 4, lower skateboard 5, collector nozzle 6, argon blowing hole 7 and groove 8 are crossed, filling pipe end 2 is fixed in pocket block 1, upper water
Mouth 2 is connected with collector nozzle 6, and mutually matched upper slide 4 and lower skateboard 5, filling pipe end are equipped between filling pipe end 2 and collector nozzle 6
2, it is respectively equipped with mutually matched steel hole 3 excessively on upper slide 4, lower skateboard 5 and collector nozzle 6, is contacted in upper slide 4 with lower skateboard 5
The plate face of upper slide 4 be equipped with a circle groove 8, the groove 8 is connect by argon blowing hole 7 with argon gas pipeline.
In the present embodiment, referring to attached drawing 2, upper slide 4 is that machine is pressed made of refractory material, can directly design with groove 8
Upper slide mold, production is simple.Groove 8 is located in the plate face for the upper slide 4 that upper slide 4 and lower skateboard 5 contact, and is conducive to fill
Timing avoids sundries from entering.Cross steel hole 3 of the groove 8 on upper slide 4 arranges that be integrally square structure.The cross section of groove 8
For the semicircle of diameter 10mm, aspect demoulds when making.Groove 8 is communicated by argon blowing hole 7 with argon gas pipeline, and argon gas is passed through, real
The purpose of existing argon gas-sealed protective casting.
Exhibition attached drawing 3,4, upper slide 4 and lower skateboard 5 either completely closed state or opening state, lower skateboard 5 begin
Cover groove 8 eventually, it is not exposed outside.
