Description
Technical field
The invention belongs to make steel field of mechanical technique, more particularly to a kind of Converter Skimming installed in converter taphole
With converter slag-resisting sliding nozzle device.
Background technology
In currently known less than 180 tons big-and-middle-sized converter taphole slide plate pushing off the slag sliding nozzle device, typical structure is
Left and right opening door formula structure, in order to reduce production cost and device total height, generally inner slider brick bottom land plate thickness is arranged to
10mm, to reduce inner slider brick public affairs open height and identical with outer sliding plate brick public affairs open height.In order to ensure the peace of device left and right opening door
Quan Xing, the height setting of usual fixed frame door-hinge seat is as far as possible low, the bottom land at general door-hinge bore center to inner slider brick groove
Distance is arranged to 120~140mm.Its shortcomings that is:Sliding nozzle device open the door to 65 ° -75 ° when, opening and closing framework spring housing with
Eyelet bolt interference on debugging frame, open angle wretched insufficiency(Normal requirement >=100 °, it is preferable more than 110 °), it is offline to change
When slide plate and the mouth of a river, narrow space is changed, operation is very difficult, and labor intensity substantially increases, while device cleaning and maintenance difficulty,
Maintenance time is grown, and has had a strong impact on resistance to material installation, part cleaning and maintenance work quality and efficiency, reduces the security of system
Energy.
For solving device left and right opening door angle wretched insufficiency problem, currently known scheme is:It is big for more than 180 tons
Type skimming device, it is 30~35mm of gross thickness by the way that inner slider brick bottom land plate thickness is increased into 20~25mm, to improve fixed frame
Frame door-hinge seat centre-height, increase device left and right opening door angle and reach 83~90 ° or so, reach requirement reluctantly, but
The problem of band inner slider brick highly increase, device total height increases, the rise of system integrated cost, it is for less than 180 tons big-and-middle
Type converter slag-resisting device, left and right opening door angle wretched insufficiency are still the technical barrier for perplexing industry.
In currently known converter taphole slide plate pushing off the slag sliding nozzle device, opening and closing framework spring cell structure is straight-through
Formula, face pressure bolt pass through spring bearer plate two side holes, screw face pressure bolt, spring pressure is by fixed rack and slides slide rail transmission
To between two slide plates, face pressure loading procedure is realized.It is primarily present problems with:In the case of opening and closing frame width is constant, bullet
Spring platen width can not be taken into account with slide rail width, when the setting of slide rail width is normal(General 35~40mm), spring bearer plate width
It is too small, general 64~65mm(8~9mm of corresponding aperture minimum wall thickness (MINI W.)), both ends easily upwarp deformation, otherwise slide rail width is less than normal, makes
Big, face pressure is fluctuated into spring pressure and transmits stability decline, and equipment safety reduces, and easily causes bleed-out accident between slide plate.
The content of the invention
In order to solve the above-mentioned technical problem, the present invention provides a kind of converter slag-resisting sliding nozzle device.
The technical scheme is that:
A kind of converter slag-resisting sliding nozzle device, including fixed frame, opening and closing framework, sliding frame, offline drive device,
Online drive device, inner nozzle pressing plate, outer mouth of a river seat, outer mouth of a river top-fastener, main protection thermal insulation board, auxiliary protection thermal insulation board, debugging
Frame, connecting plate, inner slider brick, outer sliding plate brick, inner nozzle brick and outer nozzle brick, the fixed frame and opening and closing framework switch gate
Axis connection together, sets sliding frame in opening and closing framework, opening and closing framework is correspondingly arranged solid respectively with the side position of sliding frame two
Determine slide rail, slide slide rail, outer mouth of a river seat and main protection thermal insulation board be set on sliding frame, during off-line operation, fixed frame is used
Eyelet bolt is fixed on adjusting bracket, opens opening and closing framework to 110 ° or so, outer sliding plate brick and inner slider brick are individually positioned in
Fixed frame is with sliding frame brick groove, closure opening and closing framework, being connected sliding frame and driving with offline drive device with bearing pin
Dynamic sliding frame, makes outer slide plate and inner slider centering, by outer nozzle brick in outer mouth of a river seat and with outer mouth of a river top-fastener top
Tightly, the Renewal process of resistance to material is completed;When online converter taphole skimming device inner nozzle brick, inner slider brick, outer sliding plate brick and outer water
Mouth brick was used to after the life-span, and the inner nozzle brick more renewed is simultaneously pressed on inside connecting plate, the pushing off the slag more renewed with inner nozzle pressing plate
Device is simultaneously connected with connecting plate and online drive device respectively, and driving slider bar moves back and forth, and drives outer slide plate and the outer mouth of a river
Brick is close to inner slider and steadily slided, and completes converter tapping and pushing off the slag overall process.
