Description

Produce the radio-frequency coil of nine or ten silicon cores

[technical field]

The utility model relates to the radio-frequency coil technical field, especially relates to the radio-frequency coil of nine or ten silicon cores of a kind of production.

[background technology]

at present, usage quantity is very huge at home for the silicon core, existing silicon core, in the technological process that silicon single crystal and other molten mode in material crystals district are produced, what mostly use is a kind of monocular radio-frequency coil, its principle of work is: during work by passing into high-frequency current to radio-frequency coil, make the radio-frequency coil generation current carry out induction heating to fuel rod, fuel rod upper end after heating forms melt zone, then with young brilliant in inserting the melting area of fuel rod upper end after drawing hole, then slowly promote young brilliant, raw material after fusing will be followed young brilliant the rising, form a new pillar-shaped crystal, this new pillar-shaped crystal is the finished product of silicon core or other material crystals.

the design people in first to file the radio-frequency coil patent of multinomial invention or utility model, make the domestic basic end of drawing of single silicon core, although obtained technique effect preferably in use, but the silicon core ovality problem that how to distribute more drawing hole on radio-frequency coil and draw out is a technical bottleneck always, this is mainly the restriction of radio-frequency coil distribution of current problem, if drawing hole arranges too much, just can make being heated of fuel rod irregular, local material is not thorough, namely the little molten district of corresponding drawing hole or material hole formation is in pulling process, the thawing raw material supply at place, little molten district not draw required, the corresponding radical that draws also can not get expanding, drawing hole in first to file is by changing into racket-shaped drawing hole or drop-shaped drawing hole, make the ovality problem be able to larger overcoming.

It should be explained that position, hole layout is not careless on radio-frequency coil, what drawing holes namely are set on radio-frequency coil, how arrange the drawing hole position, corresponding voltage adjustment, seedchuck structure etc. all need to do accommodation, the matching degree of equipment is also key link, so the necessary corresponding relevant device of the quantity of radio-frequency coil drawing hole forms the key components and parts that can adapt to equipment.

Find in my recent many experiments, the drainage trough or " V " shape gap drainage that arrange on racket-shaped drawing hole or drop-shaped drawing hole are obvious, can be described as an invention of radio-frequency coil technical field, broken through the circular or slightly oval general layout of original drawing hole, namely drainage trough or " V " shape gap can effectively overcome the technical bottleneck that draws the radical restriction, make drawing quantity get a promotion, and reduce for the fuel rod upper end that local temperature is too low can not material also have good benefit, obtained metastable raw material and melted; Need to prove, radio-frequency coil seems a simple copper coin, and the actual fabrication difficulty is high, thus the single price of radio-frequency coil all more than 3000 yuan, wherein making research and development are prime cost; And radio-frequency coil belongs to easily-consumed products, namely the silicon core in fuel rod upper end and pulling process all must not have any contact with radio-frequency coil, in case contact occurs just momentary arcing can appear, at this moment the replacing of radio-frequency coil is carried out in the blowing out of having to, blowing out cost, coil cost in the middle of this and to expend man-hour be all the production cost that is difficult to overcome, next radio-frequency coil time limit of service of normal conditions is about one month.

Polysilicon is the important component part of solar energy power generating industrial chain.The photovoltaic generation industrial chain is from upstream to the downstream, and the industry chain (supply chain) that mainly comprises comprises polysilicon, silicon chip, cell piece and battery component.The profit of whole photovoltaic industry and cost nearly all concentrate on the production of polysilicon link of upstream, namely use the crystal of radio-frequency coil to draw, and the crystal reduction process current consumption of reduction furnace and tooling cost account for very most of.

But; due to the appearance of European financial crisis and the lifting of foreign technology; the U.S. uses the government subsidy method to the polysilicon processing enterprise of this country; make the enterprise with hi-tech and government subsidy to sell at a low price; take high Tariff Policy for China enterprise; and European countries cancel the sun power subsidy one after another, and external order falls sharply, one tunnel slump of polysilicon price.So pendulum in face of China polysilicon enterprise is out and out existence problem.

In fact, the polysilicon price reduces, the terminal market price is also reducing, and cost of manufacture China of polysilicon also can't compare favourably with external advanced polysilicon enterprise now, and the polysilicon of our China is to have catered to the needs of photovoltaic industry development and the pattern of going into battle hastily; Be no matter the enterprise of independent research or introducing equipment, technology, compare with international advanced technology, larger gap is still arranged.

The inventor draws many silicon core technology " stove five cores " in success of the test, realized many domestic silicon cores drawing technology breakthrough simultaneously, energy-saving effect is obvious, become in Jiangsu can, the main equipment of the large polycrystalline silicon such as silicon enterprise in Luoyang, not only obtain the decrease of production, electric cost, also obtained huge business success.

Yet further reducing costs is the unremitting technology demand of contriver, only reduces production costs, and once draws out more silicon core, and the polysilicon industry can effectively enhance the competitiveness, and this is also the only way which must be passed that China's polysilicon industry is come back to life.
