Lub tshuab hluav taws xob nruab nrab yog cov khoom siv hluav taws xob uas hloov 50Hz AC lub zog mus rau qhov nruab nrab zaus (los ntawm 300Hz mus rau 1000Hz), suav nrog cov khoom siv hloov pauv zaus, lub tshuab hluav taws xob, lub tshuab hluav taws xob hauv qab, thiab lub tshuab hluav taws xob hauv ntej. Cov khoom siv hluav taws xob nruab nrab ntawm lub tshuab hluav taws xob yog tsim los ntawm fused corundum, high-purity magnesia, thiab high-purity spinel. Cov ntsiab lus ntawm binders, anti cracking agents, thiab stabilizers tau npaj raws li kev xav tau, thiab cov neeg siv tuaj yeem muab tso ncaj qha rau hauv kev siv.
Dab tsi yog qhov tuab ntawm lub cub tawg hauv qab rau nruab nrab zaus lub tshuab hluav taws xob them
Ua ntej qhuav knotting lub cub tawg hauv ob sab phlu, nteg ib txheej ntawm asbestos daim ntaub nyob rau hauv lub rwb thaiv tsev txheej ntawm lub cub tawg, thiab manually theem thiab compact txhua txheej ntawm cov khoom thaum tso.
Knotting lub cub tawg hauv qab: Qhov tuab ntawm lub cub tawg hauv qab yog li 200mm-280mm, thiab nws tau ntim nrog xuab zeb hauv ob mus rau peb zaug. Thaum sib khi ntawm tes, qhov tsis sib xws yog tiv thaiv nyob rau hauv ntau qhov chaw, thiab lub qhov cub hauv ob sab phlu tom qab ci thiab sintering tsis ntom. Yog li ntawd, yuav tsum muaj kev tswj nruj ntawm kev pub noj thickness. Feem ntau, cov xuab zeb filling thickness yuav tsum tsis pub tshaj 100 hli ib zaug, thiab cov phab ntsa rauv yuav tsum tswj tsis pub dhau 60 hli. Ntau tus neeg yuav tsum ua haujlwm ua haujlwm, nrog rau 4-6 tus neeg hauv txhua qhov haujlwm. Txhua zaus, lub pob caus yuav tsum khi rau 30 feeb, thiab tus neeg yuav tsum tau hloov. Maj mam tig ib ncig ntawm lub qhov cub thiab siv txawm tias quab yuam kom tsis txhob muaj qhov sib npaug.
Thaum lub hauv qab ntawm lub cub tawg mus txog qhov siab uas yuav tsum tau, scrape nws tiaj tus thiab tso lub crucible pwm. Hauv qhov no, kev saib xyuas yuav tsum tau them nyiaj rau kom ntseeg tau tias cov pwm crucible yog concentric nrog lub nplhaib induction, vertically kho qhov nce thiab nqis, thiab cov qauv yuav tsum tau sib txuas nrog lub cub tawg hauv qab kom ntau li ntau tau. Tom qab kho qhov sib txawv peripheral kom sib npaug, peb yuav tsum tau siv cov ntoo wedges los tuav nws kom nruj, thiab cov khoom hnyav yuav tsum tau nqa hauv nruab nrab kom nias nws kom tsis txhob txav ntawm quartz xuab zeb thaum lub qhov cub tawg.
Knotting phab ntsa rauv: Lub thickness ntawm lub cub tawg yog 90mm-120mm. Cov ntaub qhwv qhuav yog ntxiv rau hauv cov khoom siv, thiab cov ntaub yog sib npaug. Filler thickness tsis ntau tshaj 60mm. Knotting yog ua tiav manually rau 15 feeb kom txog thaum nws yog theem nrog rau sab sauv ntawm lub nplhaib induction. Tom qab knotting, lub crucible pwm tsis raug tshem tawm, thiab induction cua sov yog siv thaum ziab thiab sintering. Yog tias koj xav tshem tawm cov pwm crucible, qhwv 2-3 txheej ntawm cov ntawv xov xwm rau ntawm phab ntsa sab nrauv ntawm cov pwm crucible nrog daim kab xev ua ntej khi lub qhov cub phab ntsa. Tom qab khi cov phab ntsa rauv, nce qhov kub ntawm 900 degrees Celsius. Tom qab ntawv xov xwm tawm cov pa luam yeeb, tshem tawm cov pwm crucible sai sai. Siv ib lub thoob hlau nrog qhov siab ntawm 10-15 centimeters me dua li txoj kab uas hla ntawm cov pwm crucible thiab tus pin uas yog theem nrog rau lub qhov cub qhov ncauj raws li induction cua sov rau ziab thiab sintering.
Ceeb Toom: (Cov neeg siv tsis raug tso cai ntxiv cov ntaub ntawv lossis dej thaum siv).
