Qhov loj, zoo thiab cov nyhuv ntawm lub cub tawg sib txawv nyob ntawm seb hom iav tsim. Los ntawm kev sib piv thiab tshuaj xyuas qhov ua tau zoo ntawm cov khoom siv refractory, kev siv cov khoom siv refractory yog kawm. Tam sim no, refractories cov ntaub ntawv uas yog resistant rau high-temperature iav kua corrosion tuaj yeem txhim kho cov kev sib txuas tsis muaj zog ntawm lub qhov cub tawg. Cov hauv qab no yuav txheeb xyuas ntau yam khoom siv refractory khoom raws li tus yam ntxwv no.
1: Melting thiab casting cov ntaub ntawv:
Melting thiab casting cov ntaub ntawv yog faib nyob rau hauv ib tug tej yam ratio. Los ntawm kev kub-kub melting, txaus casting yog tiav los xyuas kom meej cov nyhuv ntawm refractory cov ntaub ntawv. Cov ntaub ntawv tom qab melting thiab casting yog tsim los ntawm alumina, zirconia thiab melting thiab casting cov ntaub ntawv. Ntawm lawv, zirconia feem ntau yog siv los tsim hluav taws xob melting rauv rau cov tsom iav tshwj xeeb. Tam sim no, hom melting thiab casting cov ntaub ntawv no tsuas yog siv nyob rau hauv lub ntiaj teb no, uas muaj ib tug muaj zog cawv. kuv lub teb chaws cov ntaub ntawv refractories yog tsim los ntawm casting tom qab fusion ntawm high-temperature cov ntaub ntawv nrog ib tug tej yam piv. Cov ntaub ntawv refractories ntawm iav kilns feem ntau yog zirconium corundum, alumina, thiab lwm yam. Siv iav kua hloov kho nyob rau hauv ntau qhov chaw los txiav txim siab ntau lawm ntau yam ntawm oxidized khoom. kuv lub teb chaws tsuas yog siv fused cam khwb cia refractory cov ntaub ntawv, thiab muaj ob peb loj-scale sawv daws yuav.
2: Silica cib cov ntaub ntawv
Silica cibcov ntaub ntawv yog cov khoom tseem ceeb refractory siv nyob rau hauv iav kilns, thiab tsuas yog siv nyob rau hauv lub sab nraud nplaim taws qhov chaw ntawm melting rauv. Qhov zoo ntawm silica cib yog ua kom ntseeg tau los ntawm kev ua haujlwm ntawm silica cib. Txawm li cas los xij, cov cua kub ntawm silica bricks tsis zoo ib yam, thiab cov khoom uas tsis yog refractory yog nquag txo cov kev pab cuam lub neej. Kev xaiv cov khoom zoo silica cib thiab cov khoom siv kub-resistant refractory ntau dua yog ib qho teeb meem uas yuav tsum tau kawm hauv kuv lub teb chaws cov iav kiln kev lag luam.
3: Magnesium hlau refractory cov ntaub ntawv
Cov iav kilns siv cov khoom siv hlau magnesium, uas yog tsim los ntawm fused magnesium bricks thiab alloy magnesium cib. Los ntawm kev khaws cia thiab khaws cia, cov txheej txheem ntsuas ntawm qhov ntau npaum yog txhim kho, thiab kev pabcuam lub neej ntawm kuv lub teb chaws cov iav kiln tau txhim kho. Txawm li cas los xij, cov hlau yuav raug siv los ntawm kev siv lub sijhawm ntev ntawm qhov kub thiab txias, uas yog qhov tseem ceeb ntawm qhov tsis muaj zog ntawm cov khoom siv magnesium hlau oxide hauv kev siv iav kiln.
