Description
【Technical field】
The present invention relates to high frequency coil technical field, more particularly, to a kind of high-frequency line for producing 12 or 13 silicon cores
Circle.
【Background technology】
At present, usage amount is very huge at home for silicon core；Mode is melted in existing silicon core, monocrystalline silicon and other material crystals areas
In the technical process of production, a kind of monocular high frequency coil is used mostly, and its operation principle is：By to high-frequency line during work
Circle is passed through high frequency electric, high frequency coil is produced electric current and carries out sensing heating, the fuel rod upper end capitiform after heating to fuel rod
Into melt zone, then by the young brilliant fusion zone by inserting fuel rod upper end after drawing hole, then slowly lifting is young brilliant, after fusing
Raw material will follow it is young brilliant rise, form a new pillar-shaped crystal, this new pillar-shaped crystal is silicon core or other materials
Expect the manufactured goods of crystal.
The design people's earlier application high frequency coil patent of multinomial invention or utility model so that the drawing of single silicon core
The country terminates substantially, although having obtained preferable technique effect in use, how more drawing is distributed on high frequency coil
Hole and the silicon core ovality problem drawn out are always a technical bottleneck, and this is mainly the limit of high frequency coil CURRENT DISTRIBUTION problem
System, if drawing hole is set excessively, the heated irregular of fuel rod will make it that, local material is not thorough, that is, corresponding drawing hole
It is corresponding to draw needed for thawing raw material supply at little Rong areas is not drawn or the little Rong areas that material hole is formed are in pulling process
Radical processed cannot also be expanded, and the drawing hole in earlier application is made by changing into racket-shaped drawing hole or drop-shaped drawing hole
Ovality problem is able to larger overcome.
It should be explained that hole position layout is not careless on high frequency coil, that is, how many are set on high frequency coil
Drawing hole, draws how hole site arranges, and the adjustment of corresponding voltage, seedchuck structure etc. are required to do accommodation,
The matching degree of equipment is also key link, so the quantity of high frequency coil drawing hole must correspond to relevant device, forms one
It is suitable for the key components and parts of equipment.
Found in my recent many experiments, the drainage trough that is set on racket-shaped drawing hole or drop-shaped drawing hole or
" V " shape gap drainage is obvious, it may be said that is an invention of high frequency coil technical field, breaches the circle of original drawing hole
Shape or somewhat elliptical general layout, that is, drainage trough or " V " shape gap can effectively overcome the technical bottleneck for drawing radical limitation, make
Quantity must be drawn to get a promotion, and for fuel rod upper end reduce local temperature it is too low can not material also have well benefit
Place, metastable raw material is obtained and has melted；It should be noted that high frequency coil seems a simple copper coin, actual fabrication
Difficulty is high, so the single price of high frequency coil, all more than 3000 yuan, making research and development therein are prime cost；It is and high
The silicon core that frequency coil belongs in easily-consumed products, that is, fuel rod upper end and pulling process must not all have any connect with high frequency coil
Touch, once momentary arcing will be occurred by contact occur, blowing out of at this moment having to carries out the replacing of high frequency coil, the blowing out among this
Cost, coil cost and to expend man-hour be all the production cost for being difficult to overcome, the next individual high frequency coil validity period of normal conditions
Limit was at one month or so.
Polysilicon is the important component of solar energy power generating industry chain.Photovoltaic generation industrial chain is from upstream to down
Trip, the industry chain (supply chain) mainly included include polysilicon, silicon chip, cell piece and battery component.The profit of whole photovoltaic industry and
Cost nearly all concentrates on the production of polysilicon link of upstream, that is, is drawn using the crystal of high frequency coil, the crystalline substance of reduction furnace
Body reduction process power consumption and processing cost account for significant portion.
But the lifting of the appearance and foreign technology due to European financial crisis, the U.S. process enterprise to the polysilicon of this country
Industry uses government subsidy method so that the enterprise with high-tech and government subsidy can be adopted with sale at low prices for Chinese Enterprises
High tariff policy is taken, and European countries cancel solar energy subsidy one after another, and external order falls sharply, and polysilicon price slumps all the way.
So it is vital conjuncture true to put in face of polysilicon enterprise of China.
In fact, polysilicon price reduction, terminal market price is also being reduced, and cost of manufacture China of polysilicon is gone back now
It can not be compared favourably with external advanced polysilicon enterprise, the polysilicon of our China has catered to solar photovoltaic industry development
The pattern for needing and going into battle hastily；Either independent research or introducing equipment, the enterprise of technology, with international advanced technology
Compare, still there is larger gap.
The present inventor draws more silicon core technologies " core of a stove five " while success of the test, realizes more silicon of the country
Core simultaneously break through by drawing technology, and energy-saving effect is obvious, turns into energy, the main choosing of Luoyang Zhong Guideng large polycrystalline silicons enterprise in Jiangsu and sets
It is standby, not only produced, electric cost is greatly lowered, also obtain huge business success.
However, it is the unremitting technology demand of inventor further to reduce cost, production cost is only reduced, is once drawn out
More silicon cores, polysilicon industry can effectively enhance the competitiveness, this be also China's polysilicon industry come back to life must be through
Road.
