Abstract
The utility model relates to a graphite jig for quartz crucible presses roof beam matched with mould with the water jacket and presses the roof beam along being equipped with on the mould body, its characterized in that: lateral wall, bottom and the circular arc between them transition position of mould body evenly are equipped with a plurality of evacuation holes, every large aperture section that the evacuation hole meets by the large aperture section of meeting with mould body internal surface I, with mould body surface II, be connected and constitute in large aperture section I and the aperture footpath section of large aperture section between II, the central line coincidence of large aperture section I, large aperture section II and aperture footpath section and to correspond the normal line of position department perpendicular with this internal profile of mould, the aperture of large aperture section II is greater than the aperture of large aperture section I, and large aperture section I embeds has white steel filter screen, and the bottom surface center of mould body is equipped with heart in the location. Its simple structure, use reliably, make and found the melt and reach more than 500 stoves, and the gas permeability is good, is showing improvement production efficiency, reduces workman intensity of labour.
Description
Technical field
The utility model relates to a kind of quartz crucible graphite jig.
Background technology
Quartz crucible is a kind of vitreous state vessel formed through high temperature melting with glass sand, is irreplaceable container in the process of manufacture order crystal silicon.Because graphite jig has thermal change coefficient little, high insulating effect, the advantage that resistance of oxidation is strong, so graphite jig can be used for producing quartz sand carrier and thermal insulator in crucible process, initial graphite jig thickness is at about 20mm, along with crucible diameter increases, melting time is also more and more longer, mould is caused to be oxidized very fast, general energy 120-150 heat, production cost is higher, it is simultaneously artificial that more mold exchange labour intensity is larger, decrease each class of output, based on this, mold thickness is increased to 50mm-80mm, be improved although heat founded by mould, but mould ventilation property is bad in melting process, and the aluminium silicate wool for filtering after using certain heat ventilation property own also decline to some extent, this has all had a strong impact on the vacuum layer quality of quartz crucible.
Summary of the invention
The purpose of this utility model is that a kind of structure solved the problem is simple, service-strong quartz crucible graphite jig in order to provide, and makes to found heat and reaches more than 500 stoves, and good permeability, significantly improve production efficiency, reduce labor strength.
The technical solution of the utility model is:
A kind of quartz crucible graphite jig, die ontology presses beam along being provided with the mould of pressing beam to match with water jacket, it is characterized in that: the sidewall of described die ontology, bottom and both arc transition position are evenly provided with and multiplely vacuumize hole, the wide aperture section I that Kong Youyu die ontology internal surface connects is vacuumized described in each, the wide aperture section II connected with die ontology outside surface, be connected to the small-bore section composition between wide aperture section I and wide aperture section II, described wide aperture section I, the medullary ray of wide aperture section II and small-bore section overlaps and vertical with the normal of die ontology Internal periphery corresponding position, the aperture of described wide aperture section II is greater than the aperture of wide aperture section I, described wide aperture section I is built-in with white steel filtering net, the bottom center of described die ontology is provided with centre of location eye.
Above-mentioned quartz crucible graphite jig, the aperture of described wide aperture section I is 6mm-8mm.
Above-mentioned quartz crucible graphite jig, the aperture of described small-bore section is 3mm-4mm.
Above-mentioned quartz crucible graphite jig, the aperture of described wide aperture section II is 12mm-14mm.
Above-mentioned quartz crucible graphite jig, the length of described wide aperture section II and small-bore section is all longer than the length of wide aperture section I.
The beneficial effects of the utility model are: adopt specially designed vacuumize hole and utilize white steel filtering net replace aluminium silicate wool, significantly enhance the ventilation property of mould, thus ensure that the vacuum layer quality of quartz crucible, ensure that mould heat is greater than 500 stoves, significantly improve production efficiency, decrease labor strength.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. mould pressure beam, 2. die ontology, 3. white steel filtering net, 4. wide aperture section I, 5. small-bore section, 6. wide aperture section II, 7. centre of location eye.
Embodiment
As shown in Figure 1, this quartz crucible graphite jig, die ontology 2 presses beam 1 along being provided with the mould of pressing beam to match with water jacket, the sidewall of described die ontology 2, bottom and both arc transition position are evenly provided with and multiplely vacuumize hole, the wide aperture section I 4 that Kong Youyu die ontology 2 internal surface connects is vacuumized described in each, the wide aperture section II 6 connected with die ontology 2 outside surface, the small-bore section 5 be connected between wide aperture section I 4 and wide aperture section II 6 forms, described wide aperture section I 4, the medullary ray of wide aperture section II 6 and small-bore section 5 overlaps and vertical with the normal of die ontology 2 Internal periphery corresponding position, the aperture of described wide aperture section II 6 is greater than the aperture of wide aperture section I 4, described wide aperture section I 4 is built-in with white steel filtering net 3, the bottom center of described die ontology 2 is provided with centre of location eye 7.The aperture of described wide aperture section I 4 is 6mm-8mm, and the aperture of small-bore section 5 is 3mm-4mm, and the aperture of wide aperture section II 6 is 12mm-14mm, and the length of described wide aperture section II and small-bore section is all longer than the length of wide aperture section I.
During work, die ontology 2 is arranged in water jacket, mould pressure beam 1 presses beam to match with water jacket, thus reach sealing, filling quartz sand in die ontology 2, utilize centrifugal force moulding stick that it is shaping, carrying out electric-arc heating by being carried in Graphite Electrodes two ends three-phase pressure reduction, heat-processed intermediate pump by pipeline, vacuumize quartz sand in hole and Bai Gang filtering net 3 pairs of die ontologies 2 and vacuumize, stop after founding 2-3 minute vacuumizing it.
