Description
(1) technical field
The utility model relates to a kind of sapphire single-crystal furnace heating member structure, is specifically related to a kind of square sapphire single-crystal furnace heating member structure.
(2) background technology
Sapphire single-crystal has unique crystalline network, excellent mechanics, optics and good thermal property, is widely used in science and technology, space vehicle, the window of high intensity laser beam device, national defence and civilian industry, etc. many fields of electronic technology.
Along with the development of science and technology, sapphire Application Areas constantly expands, and in recent years at consumer electronics product, the application development as aspects such as Mobile phone screen, table mirrors is rapid.Market not only requires that sapphire has higher quality and larger size, also needs Chang Jing enterprise constantly can reduce manufacturing cost by every means simultaneously.Reduce manufacturing cost can start with from many aspects, as reduced material cost, shortening the process time, conservation of power cost, but from the viewpoint of crystal pro cessing, then need to design sapphire crystal according to product size and shape.
Growth method of sapphire single crystal is a variety of, and kyropoulos (KY) is one of the main method commercially producing high-quality, large-size sapphire single-crystal at present.Harbin Aurora Optoelectronics Technology Co., Ltd. has the improvement kyropoulos of independent intellectual property right---and " cold core float die " is although more traditional kyropoulos is greatly improved in manufacturing cost and yield rate, but, because crystal boundary is pyriform, for square material, pyriform crystal ingot volume recovery is still lower.Therefore, be necessary to research and develop a kind of equipment that may be used for growing large-size, the square sapphire single-crystal of high-quality.
Heating member is the core of crystal growth equipment, due to the singularity of square structure---comparatively circular configuration symmetry reduces, and therefore, for ensureing that warm occasion is managed, needs consideration more during design.
(3) summary of the invention
The heating member of a kind of square sapphire single-crystal furnace thermal field structure that the utility model was announced in granted patent ZL201420050091.5 for early stage, described by further refinement, illustrate the square sapphire single-crystal furnace heating member structure that this is suitable for growing square sapphire crystal.
The purpose of this utility model is achieved in that it is the copper electrode connecting plate of a pair symmetry be square by combining, heating tungsten bar, laterally fixing tungsten bar and bondage tungsten filament form, pair of electrodes web plate is connected with positive and negative electrode respectively, heating tungsten bar is divided into six groups, every root tungsten bar is bolted on pair of electrodes web respectively by molybdenum, form U-shaped current path, total is upper opening, side tungsten bar is longitudinally evenly arranged, bottom part three layers is staggered, the tubular construction in square room is left in centre, the heating tungsten bar side tungsten bar be connected with a pair copper electrode web plate is respectively with laterally fixing tungsten bar is laterally fixing, therebetween tungsten filament bondage is used.
The utility model also has some features like this:
All there is certain radian at four angles of 1, described electrode connecting plate, and the interior length of side is 300 ~ 550mm and inside is provided with threaded hole for fixing tungsten bar.
2, described heating tungsten bar often group comprises 3 ~ 6 tungsten bars, diameter 4 ~ 8mm.
3, the fixing tungsten bar of described transverse direction comprises 1 ~ 3 group of tungsten bar, tungsten bar diameter 2 ~ 6mm, often organizes 2.
4, described heating tungsten bar or laterally fixing not coplanar with group tungsten bar with tungsten bar, namely when tungsten bar two ends are in electrode connecting plate together while when going up, for ensureing to maintain a certain distance between tungsten bar, contact short circuit is avoided, can suitably raise or lower bottom this tungsten bar, with not coplanar with organizing tungsten bar.
The beneficial effects of the utility model have: heating member structure four angles are provided with certain radian, and be conducive to the arrangement of tungsten bar on the one hand, form uniform and stable square temperature field distribution, thermograde is reasonable; Suitably can slow down the change of crystal in the thermograde of diagonal positions on the other hand, reduce long brilliant difficulty, reduce crystal internal stress, the square sapphire crystal subsurface defect grown is few, and yield rate is high.
(4) accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2-3 is vertical view.
(5) embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
Fig. 1 is square sapphire single-crystal furnace heating member structure iron, and wherein, Fig. 1 is the present embodiment heating member structural representation, and Fig. 2-3 often organizes 4 and the heating member structure vertical view often organizing 5.As can be seen from the figure, the copper electrode connecting plate 1 of a pair symmetry being square by combining of heating member structure, heating tungsten bar 3, laterally fixingly to form with tungsten bar 2 and bondage tungsten filament 4.Pair of electrodes web plate is connected with positive and negative electrode respectively, and heating tungsten bar is divided into six groups, often organizes 3 ~ 6, and Fig. 2-3 is depicted as often group 4 and the heating element arrangement situation often organizing 5.Every root tungsten bar is fixed on pair of electrodes web plate respectively by molybdenum bolt 5, and form U-shaped current path, total is upper opening, and side tungsten bar is longitudinally evenly arranged, and bottom part three layers is staggered, and the tubular construction in square room is left in centre.The heating tungsten cylinder side tungsten bar be connected with a pair copper electrode web plate by laterally fixing laterally fixing with tungsten bar, uses tungsten filament bondage therebetween respectively.
