Nruab nrab zaus hluav taws xob rauv

Cov txheej txheem rau txheej txheejNruab nrab zaus hluav taws xob rauvFeem ntau suav nrog ramming, pouring, thiab cib- tso.

Txawm li cas los xij, muab qhov xwm txheej tam sim no,Nruab nrab zaus hluav taws xob rauvFeem ntau siv quartz xuab zeb rau ramming lub qhov cub hauv ob sab phlu.

Cov ntsiab lus yog raws li nram no:

(1) Raw khoom yuav tsum tau rau induction rauv hauv ob sab phluNruab nrab zaus hluav taws xob rauv: SiO₂> 98%, Fe₂O₃ <0.05%, H₂O <0.5%, thiab tsis muaj hlau impurities, sediment, thiab av. Yog hais tias tsim nyog, hlau impurities yuav tsum xub muab tshem tawm nrog ib tug hlau nplaum, thiab cov khoom yuav tsum tau kom huv si qhuav ntawm 250℃-350 degree, ces txias rau chav tsev kub ua ntej siv.

Particle loj gradation: Yuav kom ua tiav qhov siab tshaj plaws nyob rau hauv lub rammed txheej, coarse xuab zeb (0.2-0.4 mm) yuav tsum suav txog kwv yees li 60-70%; xuab zeb zoo (hauv qab 0.2 hli) yuav tsum suav txog li 30-40%; ntawm cov hmoov hauv qab 0.06 hli yuav tsum ua 15-20%.

(2) Kev sib xyaw: Cov xuab zeb qhuav yuav tsum tau nplawm tusyees raws li qhov loj me me gradation, tom qab ntawd cov dej tsim nyog yuav tsum tau ntxiv thiab sib tov kom huv si.

(3) Ramming lub qhov cub hauv ob sab phluNruab nrab zaus hluav taws xob rauv: Thaum lub sij hawm ramming, lub crucible hauv qab yuav tsum tiaj tus, thiab cov pwm crucible yuav tsum tau kho raws nraim hauv nruab nrab kom ntseeg tau tias cov phab ntsa tuab tuab. Lub ramming quab yuam yuav tsum zoo ib yam thiab zoo ib yam nyob rau hauv tag nrho cov cheeb tsam, thiab cov khoom yuav tsum tau ntxiv nyob rau hauv cov khaubncaws sab nraud povtseg. Cov txheej txheej tshwj xeeb yog raws li hauv qab no: thawj txheej ntawm qhov cub hauv qab yog 100-200 hli, txheej thib ob yog 60-80 hli, thiab cov txheej tom ntej yog 80-100 hli txhua. Phab ntsa crucible yuav tsum yog 40-60 mm ib txheej. Tom qab txhua txheej yog rammed, saum npoo yuav tsum tau scraped tiaj tus thiab loosened ua ntej ntxiv txheej tom ntej. Lub prongs ntawm ramming diav rawg yuav tsum ntev txaus thiaj li hais tias thaum ramming lub sab sauv txheej, lub prongs yuav ncav cuag lub qis txheej los tiv thaiv delamination. Qhov ceev ntawm ramming yuav tsum ncav cuag 2.05-2.25 g / cm².
