Description
Technical field
A kind of converter top slag modifier adding apparatus is the utility model is related to, belongs to metallurgy industry pneumatic steelmaking equipment and technology
Field.
Background technology
During converter procedure produces IF steel, it is desirable to carry out pushing up slag modification after tapping.Its process is：Converter tapping
Afterwards, top slag modifier is uniformly added into the top of the slag by swivel chute after stove, its object is to reduce ladle top slag oxidisability, adjustment
Ding Zha slag system ingredients, the ability that top slag absorption is mingled with is improved, so as to improve Molten Steel Cleanliness.
During top slag modifier is added, because swivel chute feed location is fixed, top slag modifier can not uniform cloth
Material makes top slag modifier be not completely melt on ladle surface, causes top slag modifier in a certain portion of ladle to ladle top slag surface
There is bulk deposition in position, influences to push up slag modification effect, while causing the top slag modifier to waste, increase product produce be mingled with it is scarce
Sunken risk.
Utility model content
The utility model purpose is to provide a kind of converter top slag modifier and is uniformly added into device, and top slag modifier can be made equal
Even cloth improves top slag modification effect, solves problem present in background technology to ladle top slag surface.
The technical solution of the utility model is：
A kind of converter top slag modifier is uniformly added into device, comprising compressed-air hose one, compressed-air hose two, accepts
Hopper, connecting tube, swivel chute chute pipe and compressed air regulating valve.One end of connecting tube is connected with accepting hopper, connecting tube
The other end be connected with swivel chute chute pipe, one end of compressed-air hose one and compressed-air hose two connects with source of the gas respectively
Connect, the other end of compressed-air hose one and compressed-air hose two is located in swivel chute chute pipe, compressed-air hose one
Folder between the center line of blowing direction and swivel chute chute pipe of the compressed-air hose two in swivel chute chute pipe
Angle is 45 °, and compressed air regulating valve is respectively equipped with compressed-air hose one and compressed-air hose two.
A kind of described converter top slag modifier is uniformly added into device, and swivel chute chute pipe is to be in tilted layout.
A kind of described converter top slag modifier is uniformly added into device, the center line and horizontal plane of swivel chute chute pipe it
Between angle be 45 °.
A kind of described converter top slag modifier is uniformly added into device, in compressed-air hose one and compressed-air hose two
Compressed air pressure be 2-4Mpa.
A kind of described converter top slag modifier is uniformly added into device, and undertaking hopper is funnel-form.
Using the utility model, after converter tapping, during top slag modifier is added, pass through the He of compressed-air hose one
Compressed-air hose two is blown into the compressed air of certain pressure into swivel chute chute pipe, top slag modifier is uniformly sprayed to steel
Cinder inclusion layer surface, improve top slag modification effect.
The beneficial effects of the utility model are：Top slag modifier uniform distribution can be made to improve top to ladle top slag surface
Slag modifies effect and molten steel is pure, reduces the waste of top slag modifier.It is simple in construction, significant effect, it is particularly suitable for high-quality IF
The production of steel.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
In figure：Compressed-air hose 1, compressed-air hose 22, accept hopper 3, connecting tube 4, swivel chute chute pipe
