Abstract
A tungsten plate heater for sapphire crystal growth comprises arc tungsten plates, a bottom fixing ring, a circular tungsten ring, fixing bolts, through holes and fixing rivets, and is characterized in that the upper ends of the arc tungsten plates are fixed on the bottom fixing ring through the fixing rivets; the through holes are uniformly formed in the bottom fixing ring and used for connecting the bottom fixing ring with a copper electrode; the circular tungsten ring is arranged at the lower ends of the arc tungsten plates; the arc tungsten plates are connected with the circular tungsten ring through the fixing bolts. The tungsten plate heater has the benefits that the structure is reasonable; the high temperature stability is favorable; the possibility of deformation is low; the thermal field is uniform and stable; the crystal product quality is relatively high; the maintenance and use are convenient; the use cost is relatively low.
Description
Technical field
The utility model belongs to crystal processing technique field, says more specifically the sapphire crystal growth using in a kind of crystal growing furnace tungsten board heating apparatus.
Background technology
At present, what the production method of the sapphire crystal of prior art generally adopted is kyropoulos, the tungsten bar well heater that kyropoulos growing sapphire crystal is used is by bending, to assemble by the tungsten bar of certain diameter and certain length the cage structure forming, the diameter of this cage shape well heater and required tungsten bar number are selected according to a temperature processing condition for kyropoulos, but this cage shape tungsten bar heating appliances has following significantly shortcoming:
1), because the tungsten bar of bending is introduced more stress in the course of processing, make the bottom of well heater easily be out of shape fracture;
2) high temperature stability performance is poor, and easily distortion causes a temperature inequality, affects quality product;
3) inconvenience is used in maintenance, and use cost is higher.
And the filament tungsten mesh heater using is at present compared with tungsten bar cage shape well heater, although having generates heat stablizes without advantages such as bendings, but filament establishment is complicated, high and the easily damage in assembly and disassembly process to tungsten filament material requirements, inconvenient maintenance, has shortened the well heater life-span short greatly.
Summary of the invention
In order to address the above problem, it is a kind of rational in infrastructure that the utility model provides, high temperature stability performance is good, be not easy to deform, thermal field is uniform and stable, crystal product quality is higher, keep in repair easy to use, the sapphire crystal growth that use cost is lower tungsten board heating apparatus, its concrete scheme is: described sapphire crystal growth with tungsten board heating apparatus by being with arc tungsten plate, bottom set collar, circular tungsten ring, standing bolt, through hole, fixing rivet forms, it is characterized in that being fixed on the set collar of bottom by fixing rivet with the upper end of arc tungsten plate, on the set collar of bottom, through hole is evenly set, for being connected with copper electrode, lower end with arc tungsten plate arranges circular tungsten ring, band arc tungsten plate is connected with circular tungsten ring by standing bolt.
Band arc tungsten plate described in the utility model, is characterized in that being set to 30～50mm with the width of arc tungsten plate, and thickness is set to 1～3mm.
Bottom described in the utility model set collar, is characterized in that the material of bottom set collar adopts a kind of of tungsten or molybdenum, and its thickness adopts 3～5mm.
Standing bolt described in the utility model, is characterized in that the material of standing bolt adopts a kind of of tungsten or molybdenum.
Fixing rivet described in the utility model, is characterized in that the material of fixing rivet adopts a kind of of tungsten or molybdenum.
It is rational in infrastructure with tungsten board heating apparatus that the beneficial effects of the utility model are sapphire crystal growths, and high temperature stability performance is good, is not easy to deform, and thermal field is uniform and stable, and crystal product quality is higher, keeps in repair easy to usely, and use cost is lower.
