Description
Technical field
The present invention relates to technical field of metallurgical equipment, and in particular to a kind of intermediate tundish carriage of conticaster.
Background technology
Intermediate tundish carriage is the key equipment of steel-making continuous casting process, on continuous casting casting platform, for carrying pans.Press
Structure type is divided into double console mode (formula of also calling at the door), height leg formula (being also semi-door type) and Full-suspendeds.With steel-making continuous casting skill
The development of art, the fluxion of conticaster is more and more, and the capacity of pans is increasing, and general 7 stream above casting machine is all using in double
Between tank cast, but in order to obtain more preferable continuous casting billet quality, it is necessary to metallurgical function that pans have had and good flow field with
Temperature field, now preferably with single tundosh casting.Such pans are just very big, to carry this big pans, also simultaneously
Possesses the function that pans are carried out with lifting and traversing fine setting, at the scene in practical application, old intermediate tundish carriage structure has ratio
Obvious drawback, hydraulicefficiency elevation structure fault rate are higher, it is impossible to meet to require.

The operation principle of the present invention：
This new large span hydraulic lifting intermediate tundish carriage of the present invention, the improvement of three aspects is carried out.
1st, the low side guide type shoe structure type of leg 3 is improved, welds U-shaped guide groove, elevating mechanism 4 in pairs on bearing steel plate
Upper installation directive wheel 8,8 built-in rolling bearing of directive wheel, directive wheel 8 in the Y direction with guide groove while contacting, lead up and down by realization
To, the mounted in pairs of directive wheel 8, twisting resistance during lifting can be resisted, make elevating mechanism 4 keep it is parallel with track.
2nd, improve the high side guide frame form of leg 2, the welding processing guide plate on high leg 2, install on elevating mechanism 4 and be oriented to
Wheel 8,8 built-in rolling bearing of directive wheel, directive wheel 8 contact on one side in X-direction with guide plate, realize upper and lower guiding, only pacify herein
Fill a directive wheel 8.High leg one and low 3 two collective effects of directive wheel 8 of leg, can control elevating mechanism 4X directions, Y-direction
And twist motion, it is allowed to move up and down.
Improve above at two and the sliding friction of guiding mechanism is changed to rolling friction, original slide-and-guide can be greatly reduced
Caused frictional resistance, and regardless of directive wheel 8 by great side force, resistance increase very little, it might even be possible to ignore.
This just makes the stress of four hoist cylinders 5 more balance, and eliminates frictional resistance to 4 nonsynchronous enlarge-effect of elevating mechanism.
3rd, intermediate tundish carriage body frame structure for automotive is improved, strengthens support beam 1 together with increase among upper beam and the underbeam, this road is strengthened
Support beam 1 had both added the rigidity of vehicle frame, also played the effect of support pans.Spring base is housed in support beam, it is central
Between fallers when on spring base, spring produces certain decrement, and pans both ends are implemented on elevating mechanism 4, so can
To being supported in the middle part of pans, prevent that pans from working long hours lower flexure strain, will not produce positioning again.
In summary, by 3 corrective measures more than implementing, pans and intermediate tundish carriage for multiple-strand caster come
Say, following effect can be reached：Simplify device structure, mitigate weight of equipment, reduce construction investment；Single pans are middle compared to double
Tank, refractory consumption can be effectively reduced, reduce production cost；Equipment failure rate is reduced, reduces maintenance maintenance amount, improves production effect
Rate.
The interest field for being only presently preferred embodiments of the present invention, the present invention can not being limited with this certainly above,
Therefore the equivalence changes made according to scope of the present invention patent, still belong to protection scope of the present invention.
