Description
Technical field
The present invention relates to a kind of continuous casting walking cooling banks, belong to metallurgy industry continuous casting installation for casting technical field.
Background technique
Casting blank of continuous casting machine is overturn after crystallizer solidifies crystallization, withdrawal straightening machine continuous straightening, Length-fixing cutting into stepping
Cold bed carries out cooling, smooth.
Walking cooling bank is mainly made of movable rack and stationary rack two parts, and movable rack is by movable frame branch
Support, for stationary rack by the upright supports being fixed on basic platform, movable frame is by two crossbeams, Vierendeel girders and is fixed on Vierendeel girder
On column composition, and crossbeam divides affixed side crossbeam and free side crossbeam, and the promotion of movable frame uses four hydraulic cylinders straight
The form of lifting is connect, the traversing of movable frame is translated using the slide-and-guide for being installed on affixed side crossbeam and two Hydraulic Cylinders
Form.The elevation synchro drive of movable frame uses tetrad syncmotor, and translation synchronization mechanism is realized using duplex syncmotor.
When walking cooling bank works, movable frame rises and holds up and be fixed on frame in the case where four lifting hydraulic cylinders drive
Slab is lifted and moves forward a setting stroke by the movable rack on frame crossbeam, and then movable frame declines, again by slab
It is secondary to be placed on stationary rack.Later, movable frame continues the low level for being decreased below stationary rack, and moves backward one and set
Determine stroke and reach initial holding fix, prepares the movement of next stepping.Slab then with the stepping of turn over cooling bed, passes through cross
Shifting, which pushes away steel and pushes away the slab on turn over cooling bed, to be placed on collecting frame, is hung away after being stored in certain amount by ejection suspender.Stepping
Turn over cooling bed is additionally provided with the spray drainage facility of cooling slab, whole system realize the continuous coo1ing of slab, overturning, it is smooth,
Storage.
Casting blank specification mainly has: 150*150,165*165,165*225,285*200, since 285*200 casting blank section is big,
Dan Zhichong is 2.5 times of 150 slabs, causes the long-term overload operation of the equipment such as cold bed, and cold bed is caused deformation, cruciform bracing occur
Fracture, rack gear fracture, hydraulic cylinder frequent breakage serious conditions, to overhaul every time could carry out reluctantly within 8-10 hour next step
Production, equipment damage is big, and labor intensity of workers is big, and at high cost, caster work rate is low.The deformation of cold bed overall system architecture is serious,
Daily maintenance investment is big, and restriction production is bright existing, is mainly shown as:
1) for existing cold bed due to the presence of tilting gear, absolute altitude need to be with double steel sliding rail one to causing cold bed column high, column is easily-deformable
It topples, after producing 200 × 285mm, cold bed need to be adjusted and reinforcement of weld using maintenance for a long time；
2) existing cold bed movable rack is close with stationary rack designed distance, causes rack gear seat two sides without gusset, and rack gear seat is easily diverged
Deformation can not fix fixed rack, rack gear is caused to be toppled over after the deformation of rack gear seat, exacerbate the bending deformation of rack gear, and rack gear deformation is curved
The stability of cold bed column and cold bed frame is further affected after song；
3) existing cold bed column, the design of rack gear seat are thin, and column original is designed as 200 channel steel butt welding production, and rack gear seat side plate is without muscle
Plate, ability to bear is poor, and easily-deformable rack gear seat is the severely deformed root of cold bed general frame.
4) since cold bed general frame has deformed, stability is lost, maintenance repair maintenance is larger, it is mainly manifested in:
(1) cold bed movable frame deviates, and copper shoe consumption in side is big, and there are scratch situations with fixed tooth for movable frame；
(2) upright of frame frequently snaps reinforcing, and welding performance is poor, and frame needs to overhaul reset processing for a long time after snapping displacement；
(3) frame stressing is uneven, and local location stress is big, and free side girder is caused to snap fracture.
Summary of the invention
It is an object of the present invention to provide a kind of continuous casting walking cooling bank, avoids occurring deformation in process of production and rack gear is disconnected
Situations such as splitting solves the problems, such as background technique.
The technical scheme is that
A kind of continuous casting walking cooling bank includes multiple spaced apart stationary racks and movable rack, and movable rack is by activity
Frame support, stationary rack are fixed on fixed tooth column by fixed tooth support, and movable frame includes main beam in frame and is located at frame
Cruciform bracing on girder, is arranged a transition seat on the cruciform bracing of movable frame, and movable rack is fixed on movable tooth support
On, movable tooth support is fixed on transition seat by movable tooth bracket, and between movable tooth bracket and transition seat and fixed tooth support two sides are equal
Equipped with stiffener plate.
Adjustment pad is equipped between the movable tooth support and movable tooth bracket.
The transition seat is bolted on the cruciform bracing of movable frame.
The cruciform bracing of the movable frame is fixedly connected with main beam in frame by dovetail chute panel.
The fixed tooth column is square steel tube production.
Innovative point of the invention are as follows:
(1) increase transition seat on cruciform bracing, increase the stability of movable frame；
(2) optimize the distance between movable rack and stationary rack, increase stiffener plate between movable tooth bracket and transition seat, have
Effect prevents movable rack from toppling over, and guarantees the stability of movable rack, while making the replacement of lift cylinder stress reasonable；
3) movable rack cancels column, reduces component；
4) fixed tooth column is changed to square steel tube production by channel steel butt welding, and increases gusset in fixed tooth support two sides, effectively prevent solid
Fixed rack is toppled over, and guarantees the stability of stationary rack.
5) cruciform bracing copper shoe is changed to the connection of flute profile inserted block by being bolted, and replacement is convenient, improves wearability.
The beneficial effects of the present invention are: can be avoided cold bed there is deformation, cruciform bracing fracture, rack gear fracture, hydraulic cylinder
Situations such as frequent breakage, meets the production requirement of continuous production big cross section slab, reduces equipment breakdown, effectively improves casting machine
Operating rate, while mitigating maintenance mans' labor intensity.
