Cov yam ntxwv tseem ceeb ntawm cov khoom siv hluav taws xob zoo nyob hauv Castable Fire Brick Factory yog qhov tseeb los ntawm lub cev thiab tshuaj lom neeg ntawm cov cib refractory.
Cov yam ntxwv tseem ceeb ntawm cov cib zoo refractory yog txiav txim siab los ntawm lawv cov tshuaj muaj pes tsawg leeg. Yog li ntawd, cov muaj pes tsawg leeg yog lub hauv paus ntawm cov yam ntxwv ntawm cov refractory cib nyob rau hauv Castable Fire Brick Factory, thiab cov muaj pes tsawg leeg thiab kom muaj nuj nqis ncaj qha txiav txim qhov kev ua tau zoo ntawm refractory cib. Refractory cib khoom kuj yog cov khoom siv ntxhia. Cov khoom ntawm refractory bricks yog ib qho kev xav txog ntawm lawv cov minerals thiab microstructure. Yog li, qhov cuam tshuam ntawm cov khoom ua tau zoo tsis tuaj yeem txheeb xyuas los ntawm cov tshuaj muaj pes tsawg leeg. Cov ntxhia muaj pes tsawg leeg ntawm refractory cib nyob rau hauv Castable Fire Crick Factory nyob ntawm nws cov tshuaj muaj pes tsawg leeg thiab cov txheej txheem txheej txheem. Txawm hais tias cov tshuaj muaj pes tsawg leeg ntawm cov refractory bricks yog tib yam, yog tias cov txheej txheem kev ua haujlwm txawv, hom, ntau thiab crystallinity ntawm cov txheej txheem ntxhia kuj yuav txawv, thiab cov khoom ntawm cov cib refractory hauv Castable Fire Brick Factory tseem yuav yog. txawv.
Tsis tas li ntawd, cov cib refractory yog raug rau ntau yam kev siv lub cev thiab tshuaj lom neeg thaum siv kub, ua rau yaig, hnav lossis tawg, ua rau muaj kev puas tsuaj. Yog li ntawd, refractory bricks nyob rau hauv Castable Fire Brick Factory yuav tsum muaj kev ua tau zoo los hloov mus rau ntau yam kev ua haujlwm, thiab qhov kev ua tau zoo muaj feem xyuam nrog cov khoom thiab cov qauv. Txawm li cas los xij, nws yuav tsum tau hais tias qhov macrostructure ntawm refractory bricks kuj yog ib qho tseem ceeb rau kev ua tau zoo, thiab cov ntsuas kev ua tau zoo tuaj yeem cuam tshuam cov qauv sab hauv ntawm refractory cib. Piv txwv li: cov khoom uas qhia txog qib ntawm compactness - porosity, bulk density thiab tseeb ceev ntawm refractory cib nyob rau hauv Castable Hluav Taws Cib Factory; cov khoom uas qhia qhov yooj yim ntawm cov pa permeation - huab cua permeability ntawm refractory bricks; cov khoom uas qhia txog thermal zog - linear expansion ntawm refractory bricks Coefficient, thermal conductivity, tshav kub muaj peev xwm thiab kub conductivity; cov khoom ntawm txhua yam khoom - ib txwm thiab kub compressive zog, siab kub flexural zog, kub torsional zog, siab kub creep thiab elastic modulus ntawm refractory bricks nyob rau hauv Castable Hluav Taws Cib Hoobkas; Qhia cov khoom ntawm kev ua haujlwm kub kub - refractoriness, kub load softening kub, siab kub ntim stability, thermal shock kuj thiab slag kuj.
Refractory bricks, raws li lub npe qhia, yog cov kub-resistant bricks ua los ntawm high-temperature-resistant cov ntaub ntawv los ntawm ib tug tej yam ntau lawm txheej txheem. Lawv feem ntau siv hauv tsev kilns thiab ntau yam khoom siv thermal. Nrog rau kev nce qib ntawm cov cuab yeej tsim khoom thiab cov cuab yeej siv ntau lawm, nws tuaj yeem ua tiav thiab tsim tau raws li cov qauv tsim ntawm lub qhov cub, suav nrog cov qauv yooj yim thiab cov txheej txheem tshwj xeeb zoo li cov cib hauv Castable Fire Brick Factory.
Refractory bricks yuav hnav los yog puas nyob rau hauv tej yam kev mob ntawm heev mechanical kev nyuaj siab, tshuaj lom neeg kev nyuaj siab thiab thermal stress thaum lub sij hawm ib txwm siv, yog li kev tshuaj xyuas thiab tu yuav tsum tau teem caij rau kev siv lub cub tawg. Txhawm rau txhim kho lub neej kev pab cuam ntawm lub qhov cub kom zoo dua qub thiab tsim cov txiaj ntsig kev lag luam ntau dua. Nyob rau hauv cov nqe lus ntawm lub neej ntev ntawm lub kiln, nws yog ib qho tsim nyog rau lub tsev tsim, cov neeg siv thiab cov chaw tsim tshuaj paus koom nyob rau hauv kev tshawb fawb, thiab xaiv thiab tsim refractory bricks tsim nyog nyob rau hauv Castable Fire Brick Factory los txhim kho lub neej ntawm lub kiln.
Tus nqi ntawm cov cib refractory yog cuam tshuam los ntawm cov khoom siv raw, cov cuab yeej tsim khoom, cov khoom siv lub cev thiab tshuaj, qhov loj me, thiab kev siv, thiab cov nqi kuj txawv. Yuav ua li cas xaiv qhov zoo tshaj plaws refractory bricks yuav tsum muaj kev xav txog:
Ua ntej tshaj plaws, kev tsim thiab kev ua tau zoo ntawm cov kiln yuav tsum raug txiav txim siab, thiab cov khoom siv refractory tsim nyog yuav tsum raug xaiv. Muaj ntau yam khoom siv refractory, thiab nws yuav tsum tau ua kom ntseeg tau tias lawv phim cov qauv tsim ntawm lub qhov cub.
Thib ob, txhawm rau xyuas kom cov khoom lag luam zoo ntawm cov cib refractory, tsuas yog cov khoom lag luam zoo tuaj yeem txhim kho lub neej kev pab cuam ntawm kiln.
Ntxiv dua thiab, tus nqi xav txog yog tus nqi ntawm cov cib refractory hauv Castable Fire Brick Factory. Tib yam yog rau av nplaum cib thiab siab alumina cib. Vim muaj kev cuam tshuam ntawm cov khoom zoo, cov txheej txheem ntau lawm thiab lwm yam cuam tshuam, tus nqi ntawm cov tuam txhab sib txawv sib txawv, thiab cov kev pab cuam lub neej kuj txawv.
