Description
Technical field
The utility model is related to production of polysilicon equipment, more particularly to a kind of thermal insulation board fixed frame of G8 ingot furnaces.
Background technology
In recent years, in order to realize as early as possible par online and can large-scale application, each production link of upstream and downstream（Silicon material, crystalline substance
Silicon, slice, battery, component, system）All constantly is carrying out raising production efficiency, reducing production cost, promotion total quality.
And in crystal silicon link, market first choice is to carry out ingot casting using polysilicon.At home, main polycrystalline cast ingot in photovoltaic industry at present
Equipment is G6（6 × 6=36 pieces of square ingots）And G7（7 × 7=49 pieces of square ingots）.With the update iteration of technology, now in industry lead
Enterprise of army and G8 is turned one's attention to（8 × 8=64 pieces of square ingots）.
Using G8, crucible size becomes larger and the transformation of ingot casting thermal field, increases inventory, improves polycrystal silicon ingot yield rate,
And process time relative increase is few, the production capacity of separate unit ingot furnace will be significantly increased, then identical production capacity, need to produce silicon ingot
Quantity will be less, or need less human cost（Non-silicon is constant）.Relative to G5 and G6, G8 silicon ingots center possess compared with
The small side's ingot in more centers, ratio increase, and central area apart from crucible wall farther out, impurities in by crucible during ingot casting
It is of reduced contamination, average Si wafer quality will improve, and center has relatively high transfer efficiency, then contributes to promote whole ingot
Average efficiency.
Using G8, the weight and volume of the crucible of silicon ingot and placement silicon ingot increases, and the also increase in thermal field space gradually connects
It is bordering on ingot furnace body cavity.The crucible size of G5 is usually 880*880*420mm, and crucible charge amount is in 400 ~ 470KG, the crucible of G6
Size is usually in 1040*1040*540mm, and crucible charge amount is in 700 ~ 850KG, and the crucible size of G8 is 1380*1380*
650mm, crucible charge amount is then for 1500KG or more, light weight, and G8 is nearly twice of G6, and existing ingot furnace is usual
The preparation that four ingot of a stove carries out silicon ingot, but G8 silicon ingots to prepare crucible volume big, can only one ingot of a stove, original ingot furnace
Heat-insulation cage can not be just useful in the preparation process of G8 silicon ingots.
Utility model content
In order to overcome drawbacks described above, the utility model to provide a kind of thermal insulation board fixed frame of G8 ingot furnaces, Neng Goushi
Heat-insulation cage for G8 ingot furnaces.
The first technical solution of the utility model is：
A kind of thermal insulation board fixed frame of G8 ingot furnaces, including thermal insulation board further include the fixed frame of rectangle, the fixed frame
It is set per side frame level there are three crossbearer, at least five supporting plates is equidistantly equipped on each crossbearer, the supporting plate is fixed on cross
On frame, the bottom of supporting plate is equipped with hollow intubation towards the one side level on the inside of fixed frame, and the intubation is vertical with supporting plate,
The through-hole being inserted into for intubation is equipped on thermal insulation board, the intubation is inserted into through-hole on the outside of thermal insulation board, and the thickness of thermal insulation board is more than
The length of intubation, the inside of thermal insulation board are inserted into the bolt of graphite material by through-hole, and the diameter of the bolt is less than the interior of intubation
Diameter, bolt are inserted into intubation, and the length of bolt is equal to the thickness of thermal insulation board, and the end of bolt is equipped with diameter and is more than through-hole diameter
Head.
The end of the intubation passes through supporting plate, is intubated head and the tail transmission.
The beneficial effects of the utility model：
The utility model prepares the crucible used according to G8 silicon ingots for being transformed to the heat-insulation cage in existing ingot furnace
Redesign the fixed frame of heat-insulation cage thermal insulation board so that enterprise enables existing equipment to fit in the case where not increasing equipment investment
Preparation process for G8 silicon ingots.
The thermal insulation board of the utility model and the fixed form of fixed frame are simple, and thermal insulation board is passed through inserting on fixed frame first
Pipe pre-fixes, and is fixed by the bolt of graphite material.
The intubation of the utility model is further improved as head and the tail transmission, when more preferable thermal insulation board, if can not pull out slotting
Pin, can eject bolt from the end of intubation by thin bar.
