Ordinary refractory bricks:Yog tias koj tsuas yog xav txog tus nqi xwb, koj tuaj yeem xaiv cov khoom siv hluav taws xob pheej yig dua, xws li av nplaum cib. Lub cib no pheej yig. Ib lub cib tsuas yog nqi li $0.5 ~ 0.7/block. 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 raws li, nws yuav ua rau muaj kev saib xyuas tsis tu ncua vim hnav thiab tsim kua muag, thiab nws yuav tsis tuaj yeem siv tau ib txwm. Kev saib xyuas dua tuaj yeem ua rau muaj kev kho dua tshiab thiab txawm tias muaj kev puas tsuaj rau cov cuab yeej siv, uas tsis tsim nyog tau txais txiaj ntsig.
Av nplaum cib yog cov khoom tsis muaj zog acidic, nrog lub cev ntom ntom ntawm 2.15g / cm3 thiab cov ntsiab lus alumina ntawm ≤45%. Txawm hais tias lub refractoriness siab li 1670-1750C, nws yog tsuas yog siv nyob rau hauv qhov kub thiab txias ntawm 1400C. Cov khoom no tsuas yog siv tau raws li qhov yuav tsum tau ua. Qhov kub thiab txias, qee qhov tsis tseem ceeb, qhov kub thiab txias compressive zog ntawm av nplaum cib tsis siab, tsuas yog 15-30MPa, cov no muaj feem xyuam rau cov khoom ntsuas, uas kuj yog vim li cas cov av nplaum cib pheej yig.
High alumina refractory cib:High alumina bricks muaj plaub qib raws li alumina. Vim tias cov ntsiab lus txhuas ntawm cov khoom siv raw yog siab dua li cov av nplaum cib, lub npe siab alumina cib los ntawm qhov no. Raws li qib, cov khoom no tuaj yeem siv rau hauv qhov kub thiab txias ntawm 1420 txog 1550 ° C. Thaum siv, nws tuaj yeem raug nplaim taws. Qhov kub thiab txias compressive zog yog siab li 50-80MPa. Thaum raug nplaim taws, qhov kub ntawm qhov chaw tsis tuaj yeem siab dua qhov kev khiav hauj lwm kub. Qhov no feem ntau cuam tshuam los ntawm qhov ntom ntawm cov khoom thiab cov ntsiab lus alumina.
Mullite bricks:Mullite refractory bricks muaj siab refractoriness thiab ua haujlwm kub. Lawv muaj nyob rau hauv hom hnyav thiab lub teeb. Hnyav mullite cib suav nrog fused mullite cib thiab sintered mullite cib. Cov khoom Thermal shock kuj zoo; Cov khoom siv hnyav muaj cov thermal rwb thaiv tsev zoo. Cov khoom siv hnyav yog: JM23, JM25, JM26, JM27, JM28, JM30, JM32. Lub teeb yuag mullite series cov khoom lag luam tuaj yeem raug nplaim taws, thiab lub qhov hws tau sib npaug Raws li qhov tshwj xeeb lub ntiajteb txawj nqus thiab cov khoom siv raw cov ntsiab lus ntawm cov khoom, JM23 tuaj yeem siv hauv qab 1260 degrees, JM26 hauv qab 1350 degrees, thiab JM30 tuaj yeem siv rau hauv kub ntau yam ntawm 1650 degrees. Qhov no kuj yog vim li cas vim li cas mullite bricks yog kim.
Corundum cib:Corundum cib yog qib high-qib refractory cib nrog cov ntsiab lus alumina ntau dua 90%. Cov khoom no kuj muaj sintered thiab fused khoom. Raws li cov khoom siv raw, cov khoom muaj xws li: fused zirconium corundum cib (AZS, fused cam khwb cia ci), chromium corundum cib, thiab lwm yam. Qhov kub thiab txias compressive zog yog ntau dua 100MPa thiab tuaj yeem siv tau ntev hauv qhov chaw kub kub. ntawm 1,700 degrees. Tus nqi ntawm cov cib refractory no txawv ntawm ntau txhiab mus rau kaum tawm txhiab yuan ib tuj vim yog yam xws li cov txheej txheem tsim khoom thiab cov ntsiab lus raw khoom.
Alumina hollow pob cib:Alumina hollow pob cib yog cov khoom siv hluav taws xob uas kim heev, raug nqi txog li RMB 10,000 ib tuj. Vim muaj kev sib txawv ntawm kev siv ib puag ncig thiab cov txheej txheem ntau lawm, nrog rau cov ntsiab lus alumina, thiab lwm yam, tus nqi ntawm cov khoom yuav tsum siab. , raws li cov lus hais mus, tus nqi rau nyiaj.
Cov saum toj no yog ib qho kev qhia txog qhov ntom ntom, qhov kub thiab txias tsis kam thiab tus nqi ntawm refractory bricks. Feem ntau, qhov ntim ceev ntawm cov ntaub ntawv refractory yog ntsuas ua ntej tawm hauv lub hoobkas. Volume density: qhia qhov sib piv ntawm qhov loj ntawm cov khoom qhuav rau nws cov ntim tag nrho, qhia hauv g / cm3.
