Semi Silca Silicathwv cibYog cov ntawv nplaum aluminium no nrog Silica (sitio₂) raws li thawj cov khoom siv refractory xws li iav kilns thiab Coke ncu.
Cov txheej txheem ntau lawm
Kev tsim cov semi - Cov Clocka Silica tas li feem ntau cuam tshuam ntau cov kauj ruam tseem ceeb:
Raw Khoom Npaj
Cov khoom siv raw tseem silica thiab cov baux. Cov no yuav tsum tau tsoo thiab av kom tau raws li qhov muaj feem me me.
Batching thiab sib xyaw
Qhov ntau thiab tsawg ntawm aggregates thiab binders (xws li refractory av nplaum lossis cov khoom ntxiv uas tau sib xyaw) tau sib xyaw kom huv si hauv qee qhov sib npaug.
Kev sib sau
Cov khoom siv sib xyaw yog tom qab ntawd tsim rau hauv cov cib ntawm ntau yam duab nyob hauv siab. Txoj kev sib sau tau muaj xws li cov tshuab nias lossis nias hydraulic.
Kom qhuav
Cov cib tsim nyog yuav tsum tau muab ziab kom huv kom tshem tawm cov dej noo, tiv thaiv kev tawg thaum lub sijhawm tua hluav taws.
Kev tua neeg
Cov cib txav tau raug rho tawm haujlwm hauv high -} kub cov pob. Lub cev hluav taws kub thiab lub sijhawm yuav tsum tau nruj me ntsis los txhawb nqa cov pob zeb hauv av hloov pauv thiab cov khoom ruaj khov rau lub zog uas yuav tsum muaj thiab cov khoom siv refractory rau cov cib.
Kev kuaj xyuas
Tom qab tua hluav taws, semi {- Silica nrws, khaub thuas, txias crushing nyob rau hauv thauj, thiab li kab hloov mus tas li ntawm kev rov ua dua.

Cov yam ntxwv ua tau zoo
Vim lawv cov txheej txheem sib xyaw ua ke thiab cov txheej txheem ntau lawm, semi- silica refractory cib teeb hluav taws xob hauv qab no:
Kho kom haum
Feem ntau yuav tsum tau txog 1670 degree, muaj peev xwm nrog nrog siab - qhov chaw ib puag ncig.
01
Thauj khoom - Cov kabmob muag muag taw tes
Tsis pub tsawg tshaj 1250 degree, ua kom ruaj khov ruaj khov nyob rau hauv cov kub.
02
Zoo ntim ruaj khov
Semi - briclica briclica briccs ua kom pom tsawg dua ntawm Quartz Transforming rau hauv Quartz Transforming rau hauv Quartz Transforming Attacage ntawm cov av nplaum thaum Sintering thaum Sintering thaum Sintering thaum Sintering thaum Sintering thaum Sintering thaum Sintering thaum Sintering thaum Sintering thaum Sintering thaum Sintering thaum Sintering thaum Sintering thaum Sintering thaum Sintering thaum Sintering thaum Sintering thaum Sintering thaum Sintering thaum Sintering thaum Sintering thaum Sintering thaum Sintering thaum Sintering thaum Sintering thaum Sintering thaum Sintering thaum Sintering thaum Sintering thaum Sintering thaum Sintering thaum Sintering thaum Sintering thaum Sintering. Qhov no ua rau lawv ntim stability zoo dua rau ob qho tib si silica thiab av nplaum cib.
03
Zoo thermal tsis kam
Piv rau Silica Cib, semi - Silica briclic tsis kam, ua rau lawv ruaj khov nyob rau hauv ib puag ncig nrog kub hloov pauv.
04
Zoo heev corrosion
Raws li ib semi - acidic cov khoom, semi- briclica briccs muaj zoo tsis kam rau acidic gases thiab slag corrosion.
01
Tseeb
Kwv yees li 2.35 g / cm³, ib ntu kev sib tw haum rau ntau qhov cub cub.
02
Tus nqi nruab nrab
