Cov cib refractory ib txwm muaj:Yog tias koj tsuas xav txog tus nqi xwb, koj tuaj yeem xaiv cov cib refractory pheej yig dua, xws li cov cib av nplaum. Cov cib no pheej yig. Ib lub cib tsuas yog tus nqi li $ 0.5 ~ 0.7 / thaiv. Nws muaj ntau yam kev siv. Txawm li cas los xij, nws puas haum rau kev siv? Raws li qhov yuav tsum tau ua, yog tias nws tsis ua tiav, nws yuav ua rau muaj kev saib xyuas ntau zaus vim yog hnav thiab tsim kua muag, thiab nws yuav tsis tuaj yeem siv tau li qub. Kev saib xyuas ntau zaus yuav ua rau kev kho dua tshiab ntxov thiab txawm tias puas tsuaj rau cov khoom siv, uas tsis tsim nyog qhov txiaj ntsig.
Cov cib av nplaum yog cov khoom siv acidic tsis muaj zog, nrog lub cev ntom ntawm li 2.15g / cm3 thiab cov ntsiab lus alumina ntawm ≤45%. Txawm hais tias qhov refractoriness siab txog li 1670-1750C, nws feem ntau yog siv rau hauv qhov kub siab ntawm 1400C. Cov khoom no tsuas yog siv tau raws li qhov yuav tsum tau ua. Kub, qee qhov tsis tseem ceeb, qhov kub ib txwm compressive zog ntawm cov cib av nplaum tsis siab, tsuas yog 15-30MPa, cov no yog cuam tshuam nrog cov ntsuas khoom, uas kuj yog qhov laj thawj vim li cas cov cib av nplaum pheej yig.
Cov cib refractory alumina siab:Cov cib alumina siab muaj plaub qib raws li alumina. Vim tias cov ntsiab lus txhuas ntawm cov khoom siv raw yog siab dua li cov cib av nplaum, lub npe cib alumina siab los ntawm qhov no. Raws li qib, cov khoom no tuaj yeem siv rau hauv qhov kub siab ntawm 1420 txog 1550 ° C. Thaum siv, nws tuaj yeem raug rau hluav taws. Lub zog compressive kub ib txwm yog siab txog 50-80MPa. Thaum raug rau hluav taws, qhov kub ntawm qhov chaw tsis tuaj yeem siab dua qhov kub ua haujlwm. Qhov no feem ntau cuam tshuam los ntawm qhov ceev ntawm cov khoom thiab cov ntsiab lus alumina.
Cov cib mullite:Cov cib mullite refractory muaj qhov refractoriness siab thiab kub ua haujlwm siab. Lawv muaj nyob rau hauv hom hnyav thiab lub teeb. Cov cib mullite hnyav suav nrog cov cib mullite fused thiab cov cib mullite sintered. Cov khoom Thermal shock tsis kam yog qhov zoo; cov khoom sib dua muaj cov nyhuv rwb thaiv tsev zoo. Cov khoom sib dua yog: JM23, JM25, JM26, JM27, JM28, JM30, JM32. Cov khoom mullite series sib dua tuaj yeem raug rau hluav taws, thiab cov qhov hws tau faib sib npaug Raws li qhov hnyav tshwj xeeb thiab cov khoom siv raw ntawm cov khoom, JM23 tuaj yeem siv hauv qab 1260 degrees, JM26 hauv qab 1350 degrees, thiab JM30 tuaj yeem siv rau hauv qhov kub siab ntawm 1650 degrees. Qhov no kuj yog qhov laj thawj vim li cas cov cib mullite kim.
Pob zeb Corundum:Cib Corundum yog cov cib refractory qib siab uas muaj cov ntsiab lus alumina ntau dua 90%. Cov khoom no kuj muaj cov khoom sintered thiab fused. Raws li cov khoom siv raw, cov khoom suav nrog: fused zirconium corundum cib (AZS, fused cast cib), chromium corundum cib, thiab lwm yam. Lub zog compressive kub ib txwm yog ntau dua 100MPa thiab tuaj yeem siv tau ntev hauv qhov kub siab ntawm 1,700 degrees. Tus nqi ntawm cov cib refractory no sib txawv ntawm ntau txhiab txog kaum txhiab yuan ib tuj vim muaj ntau yam xws li cov txheej txheem tsim khoom thiab cov khoom siv raw.
Cov cib alumina hollow ball:Cov cib alumina hollow yog cov cib rwb thaiv tsev kim heev, kim txog li RMB 10,000 ib tuj. Vim muaj ntau yam kev siv thiab cov txheej txheem tsim khoom, suav nrog cov ntsiab lus alumina, thiab lwm yam, tus nqi ntawm cov khoom yuav tsum siab. , raws li cov lus hais mus, muaj nqis rau cov nyiaj.
Qhov saum toj no yog kev qhia txog qhov ceev, kev tiv taus kub siab thiab tus nqi ntawm cov cib refractory. Feem ntau, qhov ntim ntawm cov khoom siv refractory raug ntsuas ua ntej tawm hauv lub Hoobkas. Qhov ntim ceev: qhia txog qhov sib piv ntawm qhov hnyav ntawm cov khoom qhuav rau nws tag nrho cov ntim, qhia hauv g / cm3.
