The utility model relates to a polycrystalline silicon side's silicon core, it can make things convenient for being connected of follow -up and crossbeam silicon core, prevents that crossbeam silicon core from taking place the displacement shake, has reduced the work load and the work degree of difficulty of the production of follow -up silicon rod, has improved final product quality.
Description
Technical field
The utility model relates to a kind of polysilicon side silicon core, belongs to technical field of polysilicon production.
Background technology
At present, the technique major part of current domestic production polysilicon is all the conventional hydrogen reduction of trichlorosilane, i.e. improved Siemens, the major equipment of improved Siemens or other similar approach production major diameter polysilicons is polycrystalline silicon reducing furnaces, polycrystalline silicon reducing furnace is electrified on elongated silicon core, silicon core is heated rubescent, until surface temperature reaches 1100 degrees Celsius, pass into high-purity trichlorosilane and hydrogen, it is made at high temperature hydrogen reduction reaction to occur, make silicon packing of molecules in trichlorosilane on silicon core, its diameter is constantly increased, usually, the diameter of silicon core is at 7-10 millimeter, can be circle also can be square, or other shapes, diameter is made constantly to increase to 120-200 millimeter eventually through hydrogen reduction reaction, produce the polysilicon of high-purity solar level 6N or electronic-grade 11N.
The preparation method of existing silicon core has two kinds, traditional method is with CZ method (crystal pulling method is melted in district), namely diameter is used high-frequency induction heating at the silicon rod of 20-50 millimeter in the vacuum hearth being full of rare gas element, make its top local melting, the seed crystal of 1 diameter at 5-10 millimeter is put into from top, then slowly upwards lift, become diameter at 7-10 millimeter, the elongated silicon core of length between 1900-3000 millimeter, its shortcoming is that pull rate is slow, be generally 8-12 mm/min, the silicon core drawing 12 meters needs 4 hours, production efficiency is low, power consumption is large, facility investment is large.
Another kind uses diamond tool patterning method, and DiamondWireTechnology company of the U.S. develops the elongated silicon multiline cutting machine of numerical-control polysilicon adopting diamond wire, for the preparation of silicon core.By utilizing light gage wire line to-and-fro movement at high speed or single-way moving on workpiece to be machined of the upper diamond particle of plating, silicon rod being pressed in this lathe diamond wire and intersecting on the square gauze of composition, thus this silicon rod is cut into elongated silicon core.Its advantage is fairly obvious, and within 10-12 hour, can cut out the square silicon core of 7X7 or the 8X8 millimeter of about 200 2 meters long, power consumption is little, and working (machining) efficiency is high.
Square silicon core after current cutting is in actual production process, locate because square silicon core and crossbeam silicon core adopt molybdenum filament to bundle, prevent the landing of crossbeam silicon core, this mode not only crossbeam silicon core is easily subjected to displacement shake, and molybdenum filament also can pollute silicon rod production, in addition when tearing stove open and getting rod, also will isolate molybdenum filament from product, improve workload and work difficulty, reduce quality product.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, there is provided a kind of polysilicon side silicon core, it can facilitate connection that is follow-up and crossbeam silicon core, prevents crossbeam silicon core to be subjected to displacement shake, reduce workload and the work difficulty of the production of follow-up silicon rod, improve end product quality.
The purpose of this utility model is achieved in that a kind of polysilicon side silicon core, its side's of comprising silicon core body, and described side's silicon core body top is provided with cone boss.
The bridging arrangement of a kind of polysilicon side silicon core, it comprises two square silicon core bodies, be arranged in parallel about described two square silicon core bodies, described side's silicon core body upper end is provided with cone boss, graphite clamping petal is provided with below described side's silicon core body, described side's silicon core body lower end is plugged in graphite clamping petal, crossbeam silicon core is provided with between described two square silicon core body tops, described crossbeam silicon core offers two conical through-holes in left and right, the cone boss of described side's silicon core body upper end is plugged in the conical through-hole on crossbeam silicon core.
Compared with prior art, the utility model has following beneficial effect:
A kind of polysilicon side of the utility model silicon core, it can facilitate connection that is follow-up and crossbeam silicon core, prevents crossbeam silicon core to be subjected to displacement shake, reduces workload and the work difficulty of the production of follow-up silicon rod, improves end product quality.
