Lub teeb rwb thaiv tsev cib tau muab faib ua cov khoom sib txawv thiab sib txawv ntawm lub cev ntom ntom. Tam sim no, qhov kev faib ua feem ntawmav nplaum nplaum cibyog siab dua. Yog tias txheej rwb thaiv tsev siab dhau lawm, nws tsim nyog rau qhov sib txawv ntawm qhov kub thiab txias yuav tsum tau siv. Yog tias qhov kub thiab txias yog 1000 degree, av nplaum insulating cib tuaj yeem siv tau. Yog tias qhov kub thiab txias yog 1200 degree, high-aluminium lightweight bricks yuav tsum tau siv. Yog tias txheej rwb thaiv tsev siab tshaj 1250-1500 degree, mullite insulating cib yuav tsum tau siv. Kuj tseem muaj qee qhov sib sib zog nqus kiln, thiab cov txheej txheem ua haujlwm ntawm lub hauv ob sab phlu kuj siv cov cib sib sib zog nqus los txo qhov hnyav ntawm lub cev kiln. Hauv qhov no, alumina hollow pob cib yuav tsum tau xaiv. Cov ntsiab lus txhuas ntawm alumina hollow pob cib yog 80-90%, thiab qhov kub ntawm refractory yog 1600-1700 degree .
Txawm nws yog av nplaum, high-aluminium, los yog mullite, muaj ntau lub cev ntom ntom ntawm 1.0, 1.2, 0.8, thiab 0.6. Qhov me me ntawm lub cev ntom ntom, qhov zoo dua cov nyhuv rwb thaiv tsev. Lub rwb thaiv tsev cib ntawm alumina hollow npas muaj lub cev ntom ntom ntawm 1.2 thiab 1.0. Txawm li cas los xij, rau qee cov ntaub ntawv tshwj xeeb uas siv rau hauv kev tsim kho cov kab hluav taws xob, nws tseem yuav tsum tau siv cov rwb thaiv tsev hluav taws kub nrog lub zog me ntsis, vim tias yog tias lub cev ntom ntom me me dhau lawm, cov cib hnyav ntawm txheej ua haujlwm yuav hnav cov rwb thaiv tsev refractory cib. rau hauv cov khoom thaum siv. Kev cuam tshuam rau cov nyhuv rwb thaiv tsev.
Tau kawg, tus nqi tsis siab rau qhov sib txawv ntawm lub cev. Qhov me me ntawm lub cev ntom ntom, qhov siab dua tus nqi ntawm cov rwb thaiv tsev cib. Vim tias lub cev ntom ntom sib txawv, thermal conductivity txawv. Qhov me me ntawm lub cev ntom ntom ntawm cov rwb thaiv tsev cib, qhov thermal conductivity qis dua thiab cov nyhuv rwb thaiv tsev zoo dua, uas txuag roj ntau dua thaum siv cov kiln thiab txo cov nqi tsim khoom.
Tsis tas li ntawd, qhov me me ntawm lub cev ntom ntom, qhov hnyav ntawm cov khoom siv kiln. Qhov me me ntawm lub cev ntom ntom ntawm cov rwb thaiv tsev cib, qhov siab dua tus nqi ntawm cov khoom siv raw siv, qhov zoo dua cov nyhuv rwb thaiv tsev, tab sis tus nqi kuj yuav siab dua. Txawm li cas los xij, nyob rau hauv cov txheej txheem ntawm kev xaiv ib txheej txheej rwb thaiv tsev, qhov teeb meem ntawm lub zog yuav tsum tau txiav txim siab. Qhov me me ntawm lub cev ntom ntom ntawm lub teeb yuag rwb thaiv tsev cib, lub zog qis dua. Yog tias lub cev ntom ntom ntawm cov cib hnyav hauv cov txheej txheem ua haujlwm loj, lub cev ntom ntom ntawm cov cib hnyav yuav tsum tau txiav txim siab. Yog hais tias lub cev ntom ntom ntawm cov rwb thaiv tsev tsis zoo yog siab dhau lawm, cov nyhuv rwb thaiv tsev tsis zoo, ces nws yuav tsum tau siv cov rwb thaiv tsev firebricks nrog cov khoom siv ntau dua li cov txheej rwb thaiv tsev, txwv tsis pub cov bricks hnyav yuav zom cov insulating bricks, thiab cov nyhuv rwb thaiv tsev yuav raug cuam tshuam. Ntxiv mus, cov cib hnyav yuav txav mus raws li cov txheej txheem rwb thaiv tsev tawg, thiab cov hauv ob sab phlu ntawm tag nrho cov kiln yuav tsum tau hloov.
Txawm li cas los xij, yog tias txheej txheej ua haujlwm siv alumina hollow pob cib, tsis tas yuav xav txog qhov teeb meem ntawm lub cev me me dhau. Alumina hollow pob cib tuaj yeem ua lub luag haujlwm hauv kev rwb thaiv tsev thiab tuaj yeem tiv tauj ncaj qha rau cov nplaim taws. Nws txo cov teeb meem ntawm cov txheej txheem rwb thaiv tsev thiab cov txheej hnyav, thiab tuaj yeem ncaj qha ua ob lub luag haujlwm ntawm rwb thaiv tsev thiab siv.
Yog li ntawd, qhov ceev ntawm lub teeb yuag thermal rwb thaiv tsev bricks txawv, thiab thermal rwb thaiv tsev nyhuv kuj txawv. Nws yog qhov tsim nyog tshaj plaws los xaiv raws li qhov kub ntawm qhov cub. Lub teeb yuag thermal insulating bricks muaj kev ua haujlwm ntawm thermal rwb thaiv tsev, thiab cov thermal rwb thaiv tsev cov nyhuv txawv nrog qhov sib txawv.
