Abstract
A kind of for making steel the pre-centralising device of tundish immersed nozzle: it is primarily of bracing frame one, the bracing frame two installed with bracing frame a pair one-tenth, connecting rod between bracing frame one and bracing frame two, the sliding tray that bracing frame one and bracing frame two are respectively equipped with, be placed in the pre-centering plate in sliding tray, centre bolt hole on pre-centering plate, the bolt composition in centre bolt hole.The utility model can realize the pre-centering in the mouth of a river just can carried out at spare bit, and cast position just can directly fall, and makes time of wrapping in replacing significantly, improve and change bag rate, reduce the risk of bag in changing, do not take and change the bag time, do not repeat centering, thus guarantee the continuity of cast.
Description
Technical field
The utility model relates to a kind of centering instrument, specifically belongs to a kind of for making steel the pre-centralising device of tundish immersed nozzle.
Background technology
Steel mill is the maximization realizing production capacity, efficiency, improves casting machine casting sequence often through quick-replaceable tundish.But when wrapping in changing, usually unwrap to centering overlong time during casting position in new, cause extending the base time of staying of shell in crystallizer, in crystallizer, base shell shrinks aggravation, especially double-current conventional slab caster, usually to take into account the centering at the double-current mouth of a river, elapsed time is longer, a large amount of base shells shrinks and causes strand lapping defect quality greatly to decline, easy generation lapping defect bleed-out accident, in addition, anxiety change in packet procedures carry out the mouth of a river, casting position centering usually cannot be in order to be effective, when especially wrapping in high liquid level is changed, if base shell shrinks excessive, in wrap in wide base shell in casting position decline process and easily submersed nozzle clamped or sever, the company of causing waters unsuccessfully.Therefore, need exploitation a kind of effectively with reference to instrument, terminate to wrap between early stage in changing in middle bag baking, accurately complete the pre-centering of the mouth of a river in crystallizer leptoprosopy direction, realize to change in packet procedures new in bag arrive casting position and can directly decline, and submersed nozzle accurately can insert in crystallizer any collision not occur.
From retrieval situation, people are in order to solve Problems existing in continuous casting machine tundish nozzle centering, many improvement are carried out, the technological thought or scheme that solve this problem is proposed from different angles, but by analysis, exist: as collided in the centering process of the mouth of a river or after on-the-spot other article shock, easily physical deformation occurring, affect accuracy of alignment; Or take and limited change the bag time, or structure is more complicated, and the centering rod in centering cylinder also easily deforms, or input cost is high, maintenance cost is high deficiency also.
Utility model content
The purpose of this utility model is the deficiency overcoming prior art existence, there is provided a kind of can realize the pre-centering in the mouth of a river that spare bit just can carry out, cast position just can directly fall, make the time decreased of wrapping in replacing, reduce the risk of bag in changing, thus guarantee to pour into a mould successional for making steel the pre-centralising device of tundish immersed nozzle.
Realize the technical measures of above-mentioned purpose:
A kind of for making steel the pre-centralising device of tundish immersed nozzle, it is: it is primarily of bracing frame one, the bracing frame two installed with bracing frame a pair one-tenth, connecting rod between bracing frame one and bracing frame two, the sliding tray that bracing frame one and bracing frame two are respectively equipped with, be placed in the pre-centering plate in sliding tray, the centre bolt hole on pre-centering plate, the bolt composition in centre bolt hole.
It is: between bracing frame one and bracing frame two, be provided with reinforcement plate one.
It is: on bracing frame one and bracing frame two, be respectively equipped with reinforcement plate two.
Feature of the present utility model: the pre-centering in the mouth of a river just can carried out at spare bit can be realized, cast position just can directly fall, and makes time of wrapping in replacing significantly, improve and change bag rate, reduce the risk of bag in changing, do not take and change the bag time, do not repeat centering, thus guarantee the continuity of cast.
Accompanying drawing explanation
Fig. 1 is schematic perspective view of the present utility model;
In figure: 1-bracing frame one, 2-bracing frame two, 3-connecting rod, 4-sliding tray, 5-pre-centering plate, 6-centre bolt hole, 7-reinforcement plate one, 8-reinforcement plate two.
Detailed description of the invention
Be described further below in conjunction with accompanying drawing:
A kind of for making steel the pre-centralising device of tundish immersed nozzle: it is primarily of bracing frame 1, with bracing frame 1 to the bracing frame 22 becoming to install, the connecting rod 3 that welding or overall processing mode connect is adopted between bracing frame 1 and bracing frame 22, the sliding tray 4 that bracing frame 1 and bracing frame 22 are processed respectively, be placed in the pre-centering plate 5 in sliding tray 4, the centre bolt hole 6 that pre-centering plate is processed, the bolt composition in centre bolt hole 6.
Reinforcement plate 1 is also welded with between bracing frame 1 and bracing frame 22; Bracing frame 1 and bracing frame 22 are also welded with reinforcement plate 28 respectively, to strengthen its steadiness.
Corresponding this device of each submersed nozzle on tundish.
During use, at tundish spare bit or wait for that position is according to the azimuth axis of tundish to cast position, and the axis of hiring a car in track is fixedly connected with two the utility model with scene relatively wherein, namely according to each submersed nozzle correspondence one; Now by the pre-centering plate 5 in sliding tray 4 by the desired location being adjusted to centering that slides, and with the pre-centering plate 5 of the locked with bolts in centre bolt hole 6; Tundish is moved to the top of bracing frame 1 and bracing frame 22 by tundish car, and slowly fall, corresponding this device of the submersed nozzle on each tundish is made by adjustment, and the center line of submersed nozzle is overlapped with the center line of pre-centering plate 5, now tundish is placed on above bracing frame 1 and bracing frame 22 completely.Change after unwrapping the beginning, unwrap in directly centering is good above the crystallizer of casting position, and wrap in directly declining the mouth of a river is accurately inserted in crystallizer.
This detailed description of the invention is only the best and exemplifies, the restricted enforcement not to technical solutions of the utility model.
