Description
Technical field
This utility model belongs to major diameter kyropoulos sapphire crystal production process equipment technical field, is specifically related to a kind of heater.
Background technology
Adopting the equipment that kyropoulos produces sapphire crystal conventional is " birdcage " heater.
The tungsten bar that has as shown in Figure 1 and Figure 2 confluxes traditional heater of fixed disk, tungsten bar in this heater is bent to form " L " shape by many tungsten bars, the lower end of every tungsten bar is each attached to tungsten bar and confluxes on fixed disk, the upper end of tungsten bar is then fixed on the negative pole tungsten bar fixed disk of semicircular in shape or the positive pole tungsten bar fixed disk of semicircular in shape, and above-mentioned negative pole tungsten bar fixed disk and positive pole tungsten bar fixed disk are half-and-half disposed on the same plane. When adopting the heater processing sapphire crystal of said structure, because heater internal temperature needs to reach 2050 DEG C, then need to make tungsten bar surface temperature be maintained at 2150 DEG C, but it is very easily mutually exclusive to be half-and-half fixed on the both positive and negative polarity magnetic field that the positive pole tungsten bar on negative pole tungsten bar fixed disk and positive pole tungsten bar fixed disk and negative pole tungsten bar formed, it is easy to make tungsten bar deform; Additionally, because of the restriction of temperature, being positioned at the tungsten bar bottom heater and conflux that fixed disk is generally individually to be made up of tungsten material, tungsten material price is expensive on the one hand, adds the manufacturing cost of heater; On the other hand, the tungsten bar fixed disk that confluxes is difficult to, add man-hour, firstly the need of first cutting out a circular hole for stretching into crucible tray at tungsten bar fixed disk center of confluxing, groove milling on tungsten bar confluxes fixed disk again, then more every tungsten bar is screwed in tungsten bar and confluxes on fixed disk, not only in the above-mentioned course of processing, produced waste material is a lot, wastes resource but also adds cost; At high operating temperatures, the tungsten bar of the tungsten material crystal grain in fixed disk that confluxes easily increases expansion, cracking, and because material limits, tungsten bar confluxes the not reproducible utilization of fixed disk.
The heater that bottom bending as shown in Figure 3, Figure 4 interlocks, have the bending of upper, middle and lower three layers tungsten bar to interlock bottom the heater of this structure to form, but because the density of tungsten is big, easily soften time at 2150 DEG C, tungsten bar bottom being positioned at is sagging after being easily deformed into arc-shaped, deform sagging tungsten bar after long-time use to be easily sticked together, be very easily short-circuited, damage heater.
Utility model content
The purpose of this utility model is in that to overcome the disadvantages mentioned above existed in prior art, it is provided that a kind of simple in construction, manufacture handling ease, under the high temperature conditions tungsten bar are unlikely to deform the major diameter kyropoulos sapphire crystal heater of adhesion, long service life.
To achieve these goals, the technical solution adopted in the utility model is as follows: a kind of major diameter kyropoulos sapphire crystal heater, this heater includes many tungsten bars, every tungsten bar is provided with two bendings, two bendings are respectively formed two straightways of " L " shape, and the tungsten bar end of two short lines sections is the middle blind end of tungsten bar; Two long straightways of every tungsten bar are all parallel and are uniformly distributed by cylinder, the end of two long straightways of every tungsten bar is respectively fixed with positive pole tungsten bar fixed disk and negative pole tungsten bar fixed disk, and wherein positive pole tungsten bar fixed disk is positioned at the top of negative pole tungsten bar fixed disk; Two short lines sections of every tungsten bar press radial distribution in bottom, and are formed circular hole by the middle blind end of tungsten bar, when utilizing above-mentioned heater, only need to be fixed in the inner chamber of heater by crucible crucible tray.
In this utility model, further, this major diameter kyropoulos sapphire crystal heater also includes many group positive pole ring for fixings and negative pole ring for fixing, two long straightways of every tungsten bar respectively with often organize positive pole ring for fixing and negative pole ring for fixing is fixing is connected.
The beneficial effects of the utility model are: in heater of the present utility model, positive pole tungsten bar fixed disk is positioned at the top of negative pole tungsten bar fixed disk, and the end of the two of every tungsten bar long straightways is respectively fixed with on positive pole tungsten bar fixed disk and negative pole tungsten bar fixed disk, many tungsten bars namely can be formed after being uniformly distributed by cylinder positive and negative two-stage intersect arrange structure, this structure makes the electromagnetic field of heater be uniformly distributed in a circumferential direction, make one loop of both positive and negative polarity composition of adjacent two piece tungsten bar, electromagnetic force is caused to cancel out each other when big electric current, effectively suppress tungsten bar deformation at high operating temperatures, increase service life, tungsten bar in heater of the present utility model is directly bent by a tungsten bar and forms loop, as tradition heater, opposite need not be cross over from bottom and staggered make, increase the space of heater bottom centre, can effectively protect the crucible bottom being positioned in heater.
