Description
Technical field
Steelmaking technical field is the utility model is related to, refers in particular to middle packet filtering weir plate.
Background technology
Thickness is all consistent to existing middle packet filtering weir plate up and down, and steel outlet hole is left in middle part or middle and lower part, with
Be easy to molten steel from ladle pour down when by the steel flow port change flow field.After molten steel injection tundish, because weir plate obstructs not immediately
Submersed nozzle is flowed into, but rises molten steel face along weir plate, promotes inclusion floating.But traditional tundish weir plate steel outlet hole is single
And it is preceding in after in the same size, the function without dross inclusion adsorption.
Utility model content
The purpose of this utility model is overcome the deficiencies in the prior art, there is provided a kind of impulse-durability effect is good, service life
Middle packet filtering weir plate long and that there is filtering foreign substance in molten steel function.
To achieve the above object, technical scheme provided by the utility model is：It includes plate body, and plate body is integrally poured into a mould
Shaping, plate body is interior to be provided with skeleton, and skeleton is made of reinforcing bar or steel fibre, and skeleton can be consolidated by the form of welding or stitch
It is fixed, suspension ring are provided with the top of plate body, suspension ring bottom is extended with being connected at the top of skeleton in plate body, and plate body bottom side is provided with the filter of evagination
Slag platform, filter residue platform bottom flush with plate body bottom, use angled transition at the top of filter residue platform between plate body bottom, skeleton is positioned at filter
Slag taiwan area domain, filter residue platform are provided with several pre-and post perforative filter residue holes, and filter residue pore size distribution is in corresponding skeleton mesh, filter residue
Hole is 24-36, and filter residue hole is big, middle small multistage stepped in both ends.
Described skeleton bottom is in latticed, and middle part is square, four connection steel of the upward vertical welding in square shaped top both ends
Band, connection steel band connect with corresponding suspension ring bottom respectively.
Described plate body top is provided with enhancement layer, enhancement layer made of wire netting and tied up by steel wire on skeleton.
Described filter residue platform thickness is plate body thickness 1/3rd to half.
The middle packet filtering weir plate of this programme has following three advantages：
1st, ad hoc filter residue platform thickeies outer male structure, and skeleton strengthens in addition, while is poured into a mould by magnesia fireproof casting material, more resistant to
Molten steel washes away, it is ensured that each filter residue hole is not expanding, stable molten steel flow.
2nd, numerous aperture constructions add the contact area of resistance to material and molten steel.
3rd, the multistage stepped filter residue hole that both ends are big, centre is small, pressure is different when being passed through due to molten steel, is easy to press from both sides in molten steel
Debris is trapped in inside slag lumen pore.Weir plate is set to be provided simultaneously with filter residue function.Using the impulse-durability effect after this programme it is good, use the longevity
Life is long, good filtration effect.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
Fig. 2 is side view of the present utility model.
Fig. 3 is enhancement layer structural representation of the present utility model.
Embodiment
With reference to all accompanying drawings, the utility model is described in further detail, and preferred embodiment of the present utility model is：Ginseng
Accompanying drawing 1 is seen to accompanying drawing 3, the middle packet filtering weir plate described in the present embodiment, it includes plate body 1,1 integral castable of plate body,
Skeleton 3 is provided with plate body 1, skeleton 3 is shaped using reinforcement welding, and the top of plate body 1 is provided with suspension ring 2, and the bottom of suspension ring 2 extends plate body 1
Interior to be connected with the top of skeleton 3, the top of plate body 1 is provided with enhancement layer 6, enhancement layer 6 made of wire netting and tied up by steel wire in skeleton 3
On, the bottom side of plate body 1 is provided with the filter residue platform 4 of evagination, and the bottom of filter residue platform 4 flushes with the bottom of plate body 1, the top of filter residue platform 4 and plate
Angled transition is used between the bottom of body 1, the middle part of skeleton 3 is square, four connection steel bands of the upward vertical welding in square shaped top both ends,
Connect steel band to connect with the corresponding bottom of suspension ring 2 respectively, the bottom of skeleton 3 is in latticed, and the latticed skeleton 3 is located at filter residue platform 4
Region, the described thickness of filter residue platform 4 are the thickness of plate body 1 1/3rd to half, and filter residue platform 4 is provided with before and after several
The filter residue hole 5 run through, filter residue hole 5 are distributed in the corresponding mesh of skeleton 3, and filter residue hole 5 is in the multistage ladder that both ends are big, centre is small
Shape.The middle packet filtering weir plate of this programme has following three advantages：1st, ad hoc filter residue platform thickeies outer male structure, and skeleton increases in addition
By force, while by magnesia fireproof casting material pour into a mould, washed away more resistant to molten steel, it is ensured that each filter residue hole is not expanding, stable molten steel flow.2、
Numerous aperture constructions add the contact area of resistance to material and molten steel.3rd, the multistage stepped filter residue hole that both ends are big, centre is small, due to
Pressure is different when molten steel passes through, and is easy to inclusion content in melting steel to be trapped in inside slag lumen pore.Weir plate is set to be provided simultaneously with filter residue function.Adopt
With the impulse-durability effect after this programme is good, service life is long, good filtration effect.
Embodiment described above is only the preferred embodiment of the utility model, not limits reality of the present utility model with this
Apply scope, therefore the change that all shape, principles according to the utility model are made, it all should cover in the scope of protection of the utility model
It is interior.
