Peb kuj tuaj yeem nkag siab txog cov organic chemical muaj pes tsawg leeg ntawm cov khoom siv raw, vim tias cov chaw tsim hluav taws xob refractory cib tseem nrov heev hauv peb lub neej niaj hnub.
Thiab peb txhua tus paub tias nws cov khoom tseem ceeb txiav txim siab qhov zoo thiab cov yam ntxwv ntawm cov khoom siv rwb thaiv tsev refractory. Feem ntau hais lus, cov khoom siv raw ntawm cov ntaub ntawv rwb thaiv tsev refractory yog tag nrho los ntawm ntau cov tshuaj tua hluav taws.
Yog li ntawd, ntau thiab ntau tus neeg tsuas yog pib siv cov khoom siv raw hauv lawv lub neej txhua hnub. Qhov thib ob, peb kuj paub tias nws muaj cov yam ntxwv xws li qhov ntom ntom. Txij li cov hom refractory cib no dais qhov kub thiab txias, lawv tseem ua haujlwm ib txwm nyob rau qhov kub thiab txias. Yog li ntawd, lub ntim hnyav thiab ntom ntawm lub lag luam yog loj, uas txhais tau hais tias lub siab ceev ntawm lub refractory cib yog zoo, thiab lub compressive zog uas ua los ntawm nws yog zoo li yuav siab. Thaum kawg, refractory bricks kuj muaj ntau dua specifications rau cov porosity nyob rau hauv lawv. Tab sis tam sim no txhua leej txhua tus yuav tsum tau ua kom tiav cov kev cai nyob rau hauv tag nrho cov txheej txheem ntawm industrial ntau lawm, tab sis raws li ib tug chaw tsim tshuaj paus, nruj tswj qhia tau hais tias lub stomata muaj zoo heev. Ntawm qhov tod tes, lub thermal shock tsis kam ntawm cov khoom siv raw no zoo heev, thiab nws lub peev xwm los tiv thaiv qhov kub thiab txias hloov pauv yam tsis raug rhuav tshem. Nws tuaj yeem nqa tau ntau yam txiaj ntsig rau txhua tus. Feem ntau hais lus, refractory cib tuaj yeem muab faib ua ob hom: zoo li cov cib refractory thiab cov cib tsis muaj zog refractory. Yog li ntawd, txhua tus neeg txoj kev nkag siab ntawm ob yam tshuaj no kuj yog nyob ntawm ntau yam. Muaj ntau cov khoom siv tshuaj tshiab hauv peb lub neej niaj hnub, thiab txhua yam no ua rau peb cov khoom siv zoo siab dua. Refractory rwb thaiv tsev cov ntaub ntawv Refractory cib yog ib qho khoom siv tseem ceeb hauv kev tsim khoom. Refractory rwb thaiv tsev cov ntaub ntawv yog ib tug ruaj khov lub cev khoom. Refractory cib yog ib yam khoom siv hluav taws xob refractory. Peb yuav tsum tau soj ntsuam txhua theem ntawm cov khoom nyob rau hauv tag nrho cov txheej txheem ntawm kev tsim khoom thiab kev tsim khoom. Vim tias cov khoom no feem ntau yog siv los tsim cov phab ntsa ntawm engineering, nws tsis haum rau nws tus kheej hnav thiab tsim kua muag. Cov kev cai kuj yog siab heev. Txhawm rau txhim kho nws, nws yog ib qho tsim nyog yuav tsum tau nrog cov khoom tsim kev puas tsuaj ua ntej. Qhov hnav degree ntawm refractory bricks nyob ntawm nws tus kheej muaj pes tsawg leeg thiab cov qauv. Thaum muaj pes tsawg leeg ntawm cov khoom yog ib tug high-density ib tug siv lead ua muaj li ntawm ib tug siv lead ua, lub ntsiab lus tseem ceeb ntawm kev hnav degree yog lub zog ntawm cov pob zeb hauv av crystals uas tsim cov khoom siv raw. Lub zog siab thiab kev ua haujlwm siab ntawm cov khoom siv raw. Thaum cov ntxhia siv lead ua tsis yog-isotropic, cov siv lead ua zoo thiab cov khoom siv raw khoom zoo dua. Thaum cov khoom siv raw yog tsim los ntawm ntau yam khoom, nws cov khoom muaj feem cuam tshuam ncaj qha rau qhov ntom ntom lossis qhov porosity ntawm cov khoom siv raw, thiab kuj rau fusion compressive zog ntawm cov khoom. Yog li ntawd, nyob rau hauv cov ntaub ntawv ntawm ib tug tej yam cib nyob rau hauv chav tsev kub, lub compressive thiab compressive zog ntawm nws cov khoom yog zoo correlated. Nyob rau hauv cov ntaub ntawv ntawm calcined refractory bricks, yog hais tias cov chaw tsim tshuaj paus ntawm cov khoom tag nrho xav txog cov saum toj no yam, cov khoom tsim yuav ua tau zoo. Tsis tas li ntawd, qhov kev ua tau zoo ntawm cov khoom muaj feem xyuam nrog qhov kub thiab txias thaum siv. Qee cov khoom, xws li high-alumina refractory bricks, feem ntau xav tias nyob rau hauv qhov kub thiab txias (xws li nyob rau hauv lub ductility ntau yam hauv qab no 700-900 degree), qhov kub thiab txias, qhov kev ua tau zoo dua. Yog tias qhov ntsuas kub qis, nws tuaj yeem xav tias thaum kub nce, nrog rau kev txhim kho ntawm cov cib elastic pwm, qhov kev ua tau zoo yuav txo qis rau qee yam.
