Description

Produce the radio-frequency coil of 13 or 14 silicon core water

[technical field]

The present invention relates to the artificial lens technical field, especially relate to the radio-frequency coil of 13 or 14 silicon core water 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 the molten mode in silicon single crystal and other material crystals district is 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 the heating forms melt zone, then with young brilliant in inserting the melting area of fuel rod upper end behind the drawing hole, then slowly promote young brilliant, raw material after the 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's online application the radio-frequency coil patent of multinomial invention or utility model, although obtained preferably technique effect in the use, but how distribute more drawing hole and the silicon core ovality problem that draws out is a technical bottleneck always at radio-frequency coil, this mainly is that corresponding drawing hole or material hole form in the upper end of fuel rod little molten district is in pulling process, the local dent at place, little molten district, other melt raw material is to the little molten district trickling of depression, namely the upper end around the fuel rod between the drawing hole in middle part drawing hole or material hole is not utilized, 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, so that the ovality problem is able to larger overcoming.

Position, hole layout is not careless on radio-frequency coil, what drawing holes namely are set on the radio-frequency coil, corresponding voltage adjustment, seedchuck structure etc. all need to do accommodation, the matching degree of equipment also is 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.

In my recent many experiments, find, the white space at diversion trench place can effectively overcome the technical bottleneck that draws the radical restriction by adding drawing hole, and by add drawing hole at the diversion trench place, not only so that draw quantity and get a promotion, and for the local too high good benefit that also has of fuel rod upper end minimizing, obtained the lifting of relative smoothness; 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 the 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 all be the production cost that is difficult to overcome, next radio-frequency coil time limit of service of normal conditions is about a week.

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; because 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; can sell at a low price so that have the enterprise of hi-tech and government subsidy; 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; No matter be 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 simultaneously drawing technology breakthrough of many domestic silicon cores, energy-saving effect is obvious, become in the Jiangsu can, the main equipment of the large polycrystalline silicon enterprise such as silicon in the Luoyang, not only obtain the decrease of production, electric cost, also obtained huge business success.

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