Background technology
In the hot systems of pulling of crystals growth at present, lack thermal insulation layer at heat shielding supporting plate, the following heat of cover plate can not be obstructed
The heat that radiation zone comes, heat shielding thermal conductivity is small in addition, can not absorb more heats for coming from monocrystalline and thermal field, be unfavorable for increasing
The longitudinal temperature gradient of monocrystalline, cause single crystal growth rate low.
The content of the invention
In view of this, the utility model is directed to a kind of water conservancy diversion drum supporting device, to solve existing guide shell supporting plate
Because monocrystalline silicon growing speed is low caused by effect of heat insulation is low the problem of.
To reach above-mentioned purpose, what the technical solution of the utility model was realized in：
A kind of water conservancy diversion drum supporting device, outer rim is provided with circumferential support flat board at the top of guide shell, and circumferential support flat board is provided with
Mounting hole, ring-type carbon felt layer is fixed with the circumferential support flat board top surface, the ring-type carbon felt layer top surface is fixed with ring-type molybdenum
Layer, the ring-type carbon felt layer and ring-type molybdenum layer are respectively equipped with the via with the mounting hole face of circumferential support flat board.
Further, the ring-type carbon felt thickness degree is 10mm.
Further, the ring-type molybdenum layer thickness is 3mm.
Further, the ring-type carbon felt layer and ring-type molybdenum layer are screwed on circumferential support flat board.
Relative to prior art, a kind of water conservancy diversion drum supporting device described in the utility model has the advantage that：
A kind of water conservancy diversion drum supporting device described in the utility model, carbon felt layer and molybdenum layer are provided with support flat board, profit
With the heat-insulated good physical characteristic of carbon felt, barrier comes from heat radiation of the molten state silicon liquid to supporting plate, so as to reduce heat shielding support
Heat radiation of the plate to monocrystalline, increase the longitudinal temperature gradient of monocrystalline, improve monocrystalline throughput rate, utilize the high heat conductance of molybdenum
The physical characteristic of (140.6W/m.K), more heats for coming from monocrystalline and thermal field can be taken away, so as to increase monocrystalline longitudinal direction
Temperature, improve single crystal growth rate.
