Lub hauv paus ntawm lub molten hlau tank yog tsim los ntawm firebrick nyob rau hauv ntau yam ntaub ntawv, xws li av nplaum cib, high-aluminium cib, low-porosity cib. Thiab hais txog peb lub kaus poom, feem ntau yog siv aluminium silicon carbide carbon cib.
Lub voj voog yog txawv raws li cov khoom siv firebrick. Raws li ib txwm muaj, kev siv cov av nplaum cib ntau dua, tab sis txawm hais tias tus nqi ntawm cov av nplaum cib yog tsawg, qhov luv tshaj ntawm kev siv yog nyob nruab nrab ntawm 300-500 lub sij hawm, yog tias siv cov aluminium cib siab lossis porosity bricks tsawg, tus naj npawb. ntawm kev siv yog 600-800 zaug, yog tias siv aluminium silicon carbide carbon cib, tus lej ntawm lub voj voog yog 1200-1400 zaug.
Tsis tas li ntawd, muaj tag nrho cov kev siv ntawm refractory castable tau hauv ob sab phlu. Kev siv cov refractory castables muaj zog nyob rau hauv cov huab cua nruj, tab sis yuav tsum muaj ib tug tshwj xeeb yug me nyuam, thiab ib tug tshwj xeeb ci ntaus ntawv, tus nqi thaum ntxov yuav siab, thiab yuav tsum muaj ib co nqi rau kev yug me nyuam thiab cov khoom ci. Kev siv cov refractory castables kuj yog raws li qhov sib txawv, qhov kev pab cuam lub voj voog kuj txawv.
Kuj tseem muaj qhov sib xyaw ntawm ob, cov tswv yim sib xyaw yog siv cov av porosity tsawg lossis aluminium silicon carbide carbon cib rau ntawm phab ntsa tank, txheej txheej ruaj khov ntawm lub tank hauv qab lossis txheej ua haujlwm yog siv cov khoom siv refractory castable, qhov sib xyaw siv no muaj. nws qhov zoo, uas yog, thaum kho lub tank hauv qab, koj tuaj yeem txuag cov txheej txheem ntawm cov txheej txheem mus tas li, cov txheej txheem qub tuaj yeem siv los txo cov nqi tsim khoom. Thiab cov txheej txheem qub tsis zoo li qhov tsis tshua muaj porosity cib hauv qab, uas yuav tsum tau ua kom zoo dua ua ntej ua lub tank hauv qab hauv ob sab phlu, thiab thaum lub castable ua rau lub tank hauv qab hauv ob sab phlu, qhov xwm txheej zoo li cas tuaj yeem ncua thiab tom qab ntawd siv los ua castable.
Yog hais tias lub hauv ob sab phlu ntawm lub tank tag nrho siv txhuas silicon carbide carbon bricks, cov txheej txheem mus tas li ntawm lub hauv qab ntawm lub tank feem ntau yog siv refractory castable, txheej ua hauj lwm yog xaiv ib ncig cib, thiab cov phab ntsa ntawm lub tank yog nteg nrog ntau yam ntawm cov khoom. aluminium silicon carbide cib, vim hais tias raws li kev tsim ntawm ntau hom cib, tag nrho cov hauv ob sab phlu yuav tsis yuam kev, thiab cov kev pab cuam ntawm lub tank hauv ob sab phlu yuav txuas ntxiv.
