Kev tsom xam ntawm kev kub kub melting siab: Cov yam ntxwv thiab cov khoom siv Science ntawm Crystalline Iav Kilns
Hauv daim teb ntawm tshwj xeeb iav tsim, CRUSTALLINE cov khoom siv hluav taws xob, raws li cov khoom tseem ceeb thermal, nqa lub luag haujlwm ntawm melting high-end kho qhov muag. Cov tub ntxhais tseem ceeb ntawm hom kev lag luam no, uas yog txawv ntawm cov iav crystall, yog tias nws tuaj yeem ua kom muaj kev tsim cov pa roj crystallinamic zoo tshaj plaws rau kev tsim cov khoom lag luam siab zoo crystalline.
Crystallin iav nyob hauv txoj haujlwm tseem ceeb hauv thaj teb ntawm precision ntsuas twj tsim vim nws cov kev ua haujlwm kho qhov muag tsis zoo. Nws cov teeb meem zoo tshaj plaws (> 92%) thiab lub teeb pom kev zoo tshaj plaws rau cov khoom siv precision thiab laser resonant kab noj hniav. Hauv kev teb pej xeem, cov khoom no yog siv rau hauv kev tsim cov khoom lag luam high audio nrog nws cov cim acoustic nrog nws cov lus teb acoustic ntau tshaj {5}} Hz).
Nyob rau hauv cov lus ntawm cov ntaub ntawv sib piv, cov ternary tiv thaiv kev ua kom pom muaj cov nyhuv tseem ceeb:
Silicon Dioxide Matrix (61 ± 0. 5%) cov ntaub ntawv ruaj khov ntxig pob txha
Poov tshuaj oxide (14 ± {{0. 3%) ua raws li flux los txo viscest viscosity
Cov tshuaj txhuas (25 ± {0. 5%) plays}. {}.
Qhov tshwj xeeb no ua rau muaj kev sib tw ob npaug rau KILN hauv kev tu ncua qhov kub ntawm {}} degree thiab yaig degree thiab yaig ntawm txhuas compounds. Kev xyaum tau qhia tias kev siv zirconium corundum composite system refractory txheej txheem (Azs {{1} {{1 npaug siab dua li cov ntaub ntawv siab loj. Los ntawm kev qhia YTTRIA-stabilized zirconium txheej thev naus laus zis, lub neej pabcuam ntawm lub caij nyoog kom ntseeg tau tias qhov kev ua haujlwm tau zoo ntawm cov KILN.
Thermal Txheej Txheem Architecture thiab cov txheej txheem tswj ntawm Crystal Rauv
Cov cuab yeej siv hluav taws xob nthuav dav zoo adoptration kev sib xyaw ua ke hluav taws xob, ua ke ntawm ob lub hluav taws xob precision kub tswj kub thiab roj hluav taws xob melting:
Kuj kub npau taws melting system: Los ntawm peb-ntu Molybdenum cov khoom siv hluav taws xob hauv hluav taws xob (molyitudinal muaj tsawg dua los yog sib npaug rau 3 degree / surch
GAS AUXILIARIARIA KHAUB NCAWS: Ib tug premixed oxygen-roj burner (Nox emission<50mg/Nm³) is used to ensure the uniformity of the batch pre-melting stage
Cov DCS siab tswj system muab cov cua sov infrared infrared, tswj lub raser viscosity modules, thiab qhov kub thiab txias. 05WT%, thiab qhov kub thiab txias
Kev faib tawm cov yam ntxwv ntawm kev ua haujlwm ntawm cov khoom siv ua haujlwm
Raws li qhov sib txawv ntawm cov kev loj hlob crystal, cov cuab yeej siv tau muab faib ua ob ceg tseem ceeb:
1. Melting tswj qeb
Tag nrho cov hluav taws xob melt system: nruab nrog 99.99% platinum doped optical iav (Npuas Npaum<0.1ppm)
Kev Tshem Tawm Kbrient Kaus Melting Melting Rauv Los ntawm Kev Npaj Electromagetle Tshuab, Ua Rau Kev Npaj ntawm ultra-ntshiab Sinsonductor Ntim Khoom

Hloov kho version nrog kev ua kom tiav lub hom phiaj kev ua haujlwm thiab tsim qauv txheej txheem:
Tshwj xeeb refractory yuav tsum rau cov hmoov txhuas cov iav melting
Hauv kev tsim cov khoom lag luam qib siab-crystal iav, kev xaiv cov khoom siv refractory yog tswj hwm los ntawm peb qhov kev ua tau zoo tsis zoo los tswj hwm cov lus zoo me ntsis:
1. Tshuaj tsis taus rau cov txhuas cov latts
Qhov Oxide Oxide Concentration (ntau dua lossis sib npaug rau 25 wt% PBO) ua rau muaj kev ntxhov siab molten kev cai nrog:
- Tshwj xeeb theem kev ruaj khov hauv ib puag ncig alkaline
- Tsawg heev ntawm kev xaus kev sib cais kev sib cais
- Tsim ntawm kev tiv thaiv kab ke ntawm txheej txheem ntawm refractory-yaj interfaces
2. Thermal Cycling Eventance
Cov kev ua haujlwm ua haujlwm thov cov qauv txheej txheem kev cai ntawm kev txij nkawm txij li:
