Description
Technical field
The utility model relates to quartz crucible, is specifically related to a kind of large-diameter quartz crucible mould.
Background technology
Current domestic quartz crucible is produced and is also rested on 22 cun-24 cun productions, large size 28 cun of-32 cun of quartz crucibles also dependence on import, the technique of domestic production large size quartz crucible is also immature, run into various problem in process of production, comprise quartz crucible profile when founding not up to standard, quartz crucible inner surface vitrifying degree is low causes crystal pulling distortion etc., the key factor temperature of founding when major cause still manufactures large size quartz crucible can not reach reasonable request, the obvious difference of large size quartz crucible and small size quartz crucible is that the external diameter of crucible is large, wall thickness is thick, when normal process is founded, because the distance D1 of electrode and mould inner wall is than large (as shown in Figure 3 and Figure 4) when founding small size, the raw material of mould inner surface can not fully melt by the temperature that electrode produces in large size mould, mould temperature leak suitable for reading is large, extend the large DeGrain of melting time energy consumption, quartz crucible physical dimension is caused to be difficult to be formed, the vitrifying degree of internal surface also can reduce accordingly, crucible quality is caused to decline, easily there is a lot of problem in quartz crucible in pulling monocrystal process, distortion, crystallization, easy broken string etc.
Utility model content
Goal of the invention: the purpose of this utility model is the deficiency solving prior art existence, provides a kind of large-diameter quartz crucible mould.
Technical scheme: a kind of large-diameter quartz crucible mould described in the utility model, comprise stainless steel water cooling mold, graphite jig, the quartz sand bed of material and insulation ring, described graphite jig is arranged at stainless steel water-cooled mould inside, the inwall place of graphite jig is covered with the quartz sand bed of material, insulation ring is provided with above graphite jig, described insulation ring is the insulation ring that high temperature resistant material is made, the external diameter 100mm larger than the external diameter of the quartz sand bed of material of insulation ring, the thickness of insulation ring is 10mm, and the height of insulation ring is 100 ~ 150mm..
Further, it is suitable for reading that described insulation ring keeps being placed in graphite jig in quartz crucible arc melting process, and the distance between insulation ring and graphite jig is for being less than 10mm.
Further, described insulation ring is made up of graphite or quartz.
Further, also comprise Graphite Electrodes, described Graphite Electrodes is placed in the quartz sand bed of material through insulation ring, and the distribution in equilateral triangle between every root graphite electrode, the distance between the bottom of every root graphite electrode and graphite jig inwall is 10 ~ 20cm.
Beneficial effect: the utility model increases insulation ring in the melting process of large size quartz crucible, can fully improve crucible melting temperature, ensures quartz crucible physical dimension, improves inner surface of crucible vitrifying structure, substantially increases the quality of quartz crucible.

Wherein, it is suitable for reading that insulation ring 4 keeps being placed in graphite jig 2 in quartz crucible arc melting process, and the distance between insulation ring 4 and graphite jig 2 is for being less than 10mm; Insulation ring 4 is made up of graphite or quartz.
And, Graphite Electrodes 5 is also comprised in the utility model, described Graphite Electrodes 5 is placed in the quartz sand bed of material 3 through insulation ring 4, and the distribution in equilateral triangle between every root graphite electrode 5, the distance between the bottom of every root graphite electrode 5 and graphite jig 2 inwall is 10 ~ 20cm.
Embodiment 1:
In this enforcement, found 28 cun of quartz crucibles, the dimensional requirement of 28 cun of quartz crucibles is as table 1:
Table 1
| External diameter | 706-710mm |
| Wall thickness | 15-18mm |
| Highly | 420mm |
Meanwhile, select the high temperature material such as graphite and quartz to make insulation ring 4, the external diameter of insulation ring 4 requires to be greater than the 100mm founding quartz crucible size, thickness 10mm, height 100-150mm, and in the present embodiment, the design parameter of insulation ring 4 is as table 2:
