Description
Technical field
It the utility model is related to and did technical field of structures, and in particular to a kind of variable crucible of internal capacity.
Background technology
Quartz-ceramics is also known as fused quartz ceramic, ceramics quartz glass, quartz glass sintered article, vitreous silica sintering system
Product, it is to use vitreous silica or quartz glass as raw material, through crushing, shaping, the system prepared by series of ceramic technique such as burning till
Product, succeeded in developing at first by the U.S. in early 1960s and put into batch production.
Quartz-ceramics has cost low and high temperature refractoriness under load height, thermal coefficient of expansion is small, heat endurance is good, chemically-resistant
The good characteristics such as aggressivity is good, dielectricity is high and resistance is big.Quartz-ceramics is because having extremely low thermal coefficient of expansion, its heat shock resistance
Excellent performance, while have excellent chemical stability and extremely strong acid-resistant corrosion (insoluble in addition to hydrofluoric acid and hot sulfuric acid
In other acid), therefore silica crucible is widely used in the smeltings such as various rare metals, noble metal, special glass and photovoltaic row
In terms of the polycrystalline silicon ingot casting of industry.Especially in the silica crucible used in polycrystalline silicon ingot casting, because its size is big (1200*1200mm), wall
Thin (about 20mm), manufacture difficulty is larger.Glass horizontal annealing furnace can be made with Quartz Ceramic Roller, float glass furnace flashboard
Brick, Float Glass Annealing stove hollow roll, cast steel water nozzle, sheet metal strip heat-treatment furnace hollow roll, non-ferrous metal metallurgy are used
The mouth of a river, stopper, chute, crucible, coke oven door, and tedge liner, glass industry orifice ring, revolving sleeve, stirring rod, material
Basin, rotation pipe, radome etc., are widely used in spaceship, rocket, guided missile, radar, atomic energy, electronics, steel, refining
The industrial circle such as burnt, non-ferrous metal and glass.
In existing crucible design, the bottom of most crucible internal walls is essentially all the small portion on same horizontal plane
The bottom of the crucible internal walls divided is arranged to rough structure, and existing crucible has following ask when carrying out material control
Topic：1st, in polycrystalline cast ingot, ingot furnace is most of to set top heater and side heater respectively at the top of it with sidepiece, makes
The centre position temperature of the bottom for the crucible internal walls that must be placed in ingot furnace is relatively low, and the marginal position temperature of the bottom of crucible internal walls
Degree is higher, i.e., the isothermal level of centre position dimpling is presented in its thermal field, the material of crucible of the bottom all on same horizontal plane
Remaining degree is determined that this is allowed for when the silicon material in the centre position of crucible bottom also has remaining, crucible bottom by the thermal field of crucible
The silicon material of the marginal position in portion has been changed, and then can not accurately control crucible bottom to have one layer of simple silicon material covering, to ensure
Follow-up ingot quality；2nd, bottom is although being not easy of silicon material that the crucible of recess not flat structure enables to the region of depression
Fall, beneficial to the follow-up long crystalline substance of silicon material, but it has situations below when carrying out material control：A generally speaking crucible bottom also
It is that the remaining degree of its material is determined by the thermal field of crucible with a horizontal plane, this is allowed for when the centre of crucible bottom
When the silicon material of position also has remaining, the silicon material of the marginal position of crucible bottom has been changed, and then can not accurately control crucible bottom
There is one layer of simple silicon material covering, to ensure follow-up ingot quality；Because crucible is typically using made of mould, bottom is b
Rough structure so that need corresponding formulation mould, cost is higher and process is more troublesome；3rd, it is once made in crucible
Internal volume has just been fixed up, if the excessive waste that heating energy source is will result in when processing small article of its volume,
And it is not easy to operate.If its volume is too small cannot to be used for Large Parts Machining article.
Mostly use two kinds of techniques at present：Grouting process and gel-casting.Grouting process belongs to traditional handicraft, and it has as follows
Feature：Technical maturity；Structure is uneven；Green strength is low；Density is higher；Yield rate low cost is high.Day can not increasingly be met
Become the casting ingot process requirement of development.Gel-casting is technique emerging in recent years, and its feature is：Green strength is high；Structure is equal
It is even；It is adapted to make large scale crucible；But its density is low, complex process, cost are higher.As the raising of casting ingot process is to crucible purity
It is required that the increasingly harsh, reduction of crucible cost also constantly proposes new requirement, grouting process and gel-casting all can not once into
The high-purity composite crucible of type, cost pressure also increasingly increase.Therefore, it is badly in need of a kind of brand-new technique to meet that crucible technique is simple, low
Cost, high-purity, high density, even structure crucible come meet ingot casting market continuous development the needs of.
