Abstract
The utility model discloses a kind of new-type 150 feather weight sapphire kyropoulos growth furnace, comprise side screen and shield with side the end be connected and shield, described side screen comprises the interior screen set up successively from inside to outside, middle screen and outer screen, described interior screen, middle screen and outer screen be all by the some pieces of identical arc Zirconium oxide fibre Slab element fissure of displacement be spliced cylindrical, screen of the described end is rounded, centre is provided with a circular hole, and screen of the described end is combined by some pieces of zirconium oxide fiber boards.For preventing cracking and good effect of having collapsed while the utility model can strengthen heat insulation effect, its heat-shock resistance is improved, and Zirconium oxide fibre Slab element break down after the fiberboard of available same size carry out local replacing, without the need to by whole side screen and end screen replacing, saved cost.Gap simultaneously between fritter makes fiberboard can discharge the stress expanding and produce when high temperature, reduces the possibility that extruding produces cracking, substantially increases the work-ing life of sapphire kyropoulos growth furnace.
Description
Technical field
The brilliant stove design field of a kind of new-type length of the utility model, particularly relates to a kind of structure of new-type sapphire kyropoulos growth furnace internal oxidation zirconium fiberboard.
Background technology
The sapphire crystal growth method that first kyropoulos is proposed in nineteen twenty-six by Kyropoulos.The method is the seed crystal and melt contacts of catching a cold one, if the temperature at interface is lower than zero pour, then seed crystal starts growth.For making crystal constantly grow up, just need reduce the temperature of melt gradually, to transfer and rotating crystal simultaneously, to improve the temperature distribution of melt, also can slowly or by stages on carry crystal, to expand radiating surface.
The feature that this long crystallization has compared to crystal pulling method is: be not 1. suggested crucible in the process of whole crystal growth, do not contact, so just accurately can control its speed of cooling with crucible, reduces the pollution of thermal stresses and crucible.2. during crystal growth, solid-liquid interface is among melt encirclement, and the thermal perturbation of such bath surface and mechanical disturbance can be reduced by melt so that eliminate before arrival solid-liquid interface.3. there is movement and the rotation of crystal in crystal growing process, be easily subject to mechanical vibration impact, usually show less unrelieved stress and defect concentration.
Zirconium oxide fiber board insulation side screen is adopted to be applied to the feature that sapphire kyropoulos growth furnace has technological design uniqueness, and Zirconium oxide fibre has that purity is high, density is low, fusing point is high, life-time service temperature is high, the stable performance of thermal conductivity low and high temperature, the feature such as corrosion-resistant, anti-oxidant, pollution-free, be the novel material of the superhigh temperature resistant of most significant end in current domestic and international market, heat insulation, insulation.Its advantage had is to reduce long brilliant maximum power; Zirconium oxide fiber board at high operating temperatures non-volatile, temperature of thermal field gradient stabilization is good; Compared with the sapphire grown with traditional side screen protection adiabator, better quality etc.
Use at present sapphire growth furnace in, adopt overall or bulk zirconium oxide fiber board easily to occur cracking as heat shielding, the situation such as collapse.This technical barrier cannot be fundamentally solved under known condition.The situation occurring this type of in use all cannot be avoided for known several refractory materialss.
Utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of new-type 150 feather weight sapphire kyropoulos growth furnace.
Technical scheme: for solving the problems of the technologies described above, the new-type 150 feather weight sapphire kyropoulos growth furnace of the one that the utility model provides, comprise side screen and shield with side the end be connected and shield, described side screen comprises the interior screen set up successively from inside to outside, middle screen and outer screen, described interior screen, middle screen and outer screen be all by the some pieces of identical arc Zirconium oxide fibre Slab element fissure of displacement be spliced cylindrical, screen of the described end is rounded, centre is provided with a circular hole, and screen of the described end is combined by some pieces of zirconium oxide fiber boards.
Further, described side screen is highly 1000mm, and internal diameter is 250mm, and external diameter is 385mm.
Further, described end Folding-Screen is highly 50mm, and diameter is 550mm.
Further, described zirconium oxide fiber board two ends are respectively equipped with a trapezoidal engagement part.
Further, described interior screen is 10 layers, thick 40mm, and by 12 pieces of zirconium oxide fiber boards, the fissure of displacement splices.
Further, middle screen is divided into 9 layers, thick 40mm, and by 12 pieces of zirconium oxide fiber boards, the fissure of displacement splices.
Further, described outer screen is divided into 8 layers, thick 40mm, and by 12 pieces of zirconium oxide fiber boards, the fissure of displacement splices.
Further, the circular hole aperture in the middle of end Folding-Screen is 110mm.
In the sapphire kyropoulos growth furnace zirconium oxide fiber board side screen that the utility model provides uses, screen, middle screen, outer screen three the screen fissure of displacement are piled up, three screen layered shaping, every one deck, again by the mode that zirconium oxide fiber board is engaged mutually, shields the mode that use 10 pieces of zirconium oxide fiber boards are engaged mutually at the bottom of the screen zirconium oxide fiber board of sapphire kyropoulos growth furnace side.While not affecting heat insulation effect, reduce the possibility ftractureing and collapse, add the work-ing life of growth furnace, be specially adapted to 150 feather weight sapphire bubble growth method growths.
Beneficial effect: the utility model in terms of existing technologies, the processing of convenient growth furnace side screen, be convenient to transport and assembling simultaneously, for preventing cracking and good effect of having collapsed while heat insulation effect being strengthened, because zirconium oxide fiber board forms present fritter by original large bulk, its heat-shock resistance is improved, and Zirconium oxide fibre Slab element break down after the fiberboard of available same size carry out local replacing, without the need to whole side screen and end screen being changed, save cost.Gap simultaneously between fritter makes fiberboard can discharge the stress expanding and produce when high temperature, reduces the possibility that extruding produces cracking, substantially increases the work-ing life of sapphire kyropoulos growth furnace.
