Kev xaiv ntawm refractory bricks rau tundishing feem ntau yog nyob ntawm daim ntawv thov tshwj xeeb thiab txheej txheem kev lag luam. Cov kev lag luam sib txawv thiab qhov kub thiab txias yuav xav tau ntau hom hluav taws kub refractory cib. Cov hauv qab no yog qee yam hom refractory cib, koj tuaj yeem xaiv qhov yog raws li koj qhov xwm txheej tshwj xeeb:
Refractory Silica cib: haum rau cov cua kub kub, smelting furnaces, crucibles, thiab lwm yam., thiab tuaj yeem tiv taus qhov kub thiab txias thiab tshuaj yaig.
High alumina refractory bricks: haum rau txhuas smelting, iav kilns, sintering furnaces, thiab lwm yam., thiab muaj peev xwm tiv taus kub thiab corrosion.
Magnesia-aluminium refractory bricks: haum rau converters, steel smelting, cement kilns, thiab lwm yam., nrog zoo kub kuj thiab corrosion kuj.
Silicon carbide refractory hluav taws cib: haum rau high-temperature electric furnaces, refractory ceramic kilns, thiab lwm yam., nrog zoo heev kub-resistant.
Aluminium silicate fiberboard: Haum rau thermal rwb thaiv tsev cov ntaub ntawv uas muaj peev xwm muab thermal rho tawm nyob rau hauv ib puag ncig kub.
Tundish yog ib qho khoom siv feem ntau siv hauv kev lag luam steel smelting los tiv thaiv thiab tswj qhov kub ntawm cov hlau molten thaum nws ntws tawm ntawm lub tshuab hluav taws xob los yog hloov pauv kom ntseeg tau qhov zoo ntawm cov hlau molten. Nov yog qee cov kauj ruam dav dav rau kev teeb tsa thiab siv cov pob zeb refractory hauv tundishes:
Xyuas kom cov cuab yeej huv si: Ua ntej txhim kho cov cib refractory, xyuas kom cov chaw sab hauv ntawm tundish huv si thiab tsis muaj khib nyiab lossis av. Qhov chaw huv si ua rau muaj kev txhim kho kom zoo thiab lub neej ntev ntawm cov hluav taws kub refractory cib.
Npaj cov cib refractory: Xaiv cov khoom tsim nyog ntawm cov cib refractory thiab txiav los yog tsim lawv raws li xav tau los xyuas kom meej tias lawv haum cov duab thiab qhov loj ntawm tundish.
Nruab refractory bricks: Muab refractory hluav taws cib rau ntawm phab ntsa sab hauv ntawm tundish raws li tus tsim los yog cov chaw tsim khoom cov lus pom zoo. Feem ntau, refractory hluav taws cib yuav tsum tau muab tso ze rau tsim ib txheej ntawm rwb thaiv tsev. Nco ntsoov tias tsis muaj qhov sib txawv ntawm cov cib refractory los tiv thaiv kom tsis txhob muaj cua sov.
Siv cov kua nplaum uas tiv taus hluav taws zoo: Thaum txhim kho cov cib refractory, cov kua nplaum uas tiv taus hluav taws tuaj yeem siv los sau cov qhov khoob me me lossis cov voids los txhim kho lub foob. Cov nplaum nplaum uas tiv taus hluav taws yog feem ntau cov nplaum nplaum uas muaj peev xwm tiv taus qhov kub thiab txias.
Ua kom Tightness: Xyuas kom cov cib refractory yog ruaj khov rau cov phab ntsa sab hauv ntawm tundish kom tsis txhob txav los yog xoob thaum siv.
Kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua: Lub refractory bricks ntawm tundish yuav puas los ntawm kub kub thiab tshuaj tua kab mob thaum siv. Yog li ntawd, kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua yog qhov tseem ceeb heev. Kev puas tsuaj refractory bricks yuav tsum tau hloov nyob rau hauv lub sij hawm los xyuas kom meej cov kev ua tau zoo thiab kev ruaj ntseg ntawm cov khoom.
Kev ruaj ntseg yog qhov kev txhawj xeeb tseem ceeb thaum txhim kho thiab siv cov pob tundish. Xyuas kom meej tias txhua qhov kev ua haujlwm tau ua raws li cov qauv kev nyab xeeb thiab cov cai tswj kev tiv thaiv kev sib tsoo. Kev txhim kho thiab kev saib xyuas ntawm refractory bricks yog qhov zoo tshaj plaws ua los ntawm tus kws tshaj lij lossis kws tshaj lij.
Xaiv qhov tsim nyog refractory cib raws li kev siv tshwj xeeb, kub thiab tshuaj lom neeg ib puag ncig ntawm chav tsev.
