Refractory pob (pob kub cia)
1. Cov pob alumina siab muaj cov yam ntxwv ntawm muaj zog oxidation tsis kam thiab slag tsis kam. Cov pob refractory ceramic tuaj yeem hloov pauv tau yooj yim thiab ntxuav, thiab tuaj yeem rov siv tau.
2. Cov ntsiab lus tseem ceeb ntawm cov pob refractory: Φ40mm Φ50mm Φ60mm Φ70mm
3. Cov khoom siv ntawm cov khoom siv refractory pob tau muab faib ua: high-aluminium, corundum, thiab zirconium corundum.
4. Muaj ntau hom khoom siv refractory, uas tuaj yeem siv rau hauv qhov kub thiab txias qis dua qhov hloov pauv, hloov pauv, hloov pauv hydrogenation, tso tsheb hlau luam desulfurization, thiab cov khoom siv refractory thiab cov khoom siv cua sov uas tau hloov los ntawm cov cua kub tawg hauv cov hlau thiab hlau kev lag luam .
5. Cov cua sov khaws cov plooj (refractory ball) muaj qhov zoo ntawm lub zog siab thiab hnav tsis kam; loj thermal conductivity thiab muaj peev xwm ua kom sov, ua kom sov zoo dua qub; tshav kub cia cov plooj (porcelain ball) muaj cov cua sov zoo ruaj khov thiab tsis yooj yim tawg thaum qhov kub hloov pauv sai. Lub pob ntim cua sov tshwj xeeb tshaj yog tsim rau cov cua sov khaws cia ntawm cov cua sov ntawm cov khoom sib cais huab cua thiab cov cua sov ua kom sov cua sov rauv ntawm cov hlau cog. Lub tshav kub cia pob ua ob zaug ua ntej cua sov thiab cua sov, thiab cov cua sov khaws cov pob zeb ua kom kub hnyiab sai mus txog cov hlau ntxig kom sov cov ntawv. Yuav tsum muaj.
6. High alumina ceramic refractory ball, siab alumina cov ntsiab lus, siab ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom alumina cov khoom ua kom zoo nkauj, ua kom sov zoo, tiv tshav kub kub zoo, siab alumina ceramic pob tau dav siv, thiab tuaj yeem siv ua tshuaj lom neeg. Siab alumina ceramic pob kuj tseem tuaj yeem siv ua kev sib tsoo xov xwm. High alumina ceramic refractory ball tau siv dav hauv tshuaj, tshuab, hluav taws xob, kev tiv thaiv ib puag ncig thiab lwm yam haujlwm.
1. High-aluminium refractory pob feem ntau yog hais txog cov ntsiab lus ntawm Al2O3. Lub ntsiab lus nrov yog cov ntsiab lus ntawm txhuas oxide hauv cov khoom siv raw ntawm cov khoom siv refractory. Cov ntsiab lus txhuas txiav txim siab qib ntawm lwm yam khoom sib txawv. Yog li ntawd, nws yog lub ntsiab lus ua tau zoo ntawm cov pob refractory. High-aluminium refractory pob tuaj yeem faib ua plaub hom raws li cov ntsiab lus txhuas: qib qib qib siab aluminium cov ntsiab lus 75; qib thib ob qib high-aluminium pob, ZN-65 nrog 65% txhuas cov ntsiab lus; qib peb-qib high-aluminium pob, nrog cov ntsiab lus txhuas 55% ZN-55.
2. Tej ceev yog tus piv ntawm hauv qhuav huab hwm coj ntawm lub refractory lub pob mus rau nws tag nrho ntim, thiab lub tsev yog g / cm3. Qhov ntom ntom ntom ntom feem ntau qhia txog kev cog lus ntawm lub pob hluav taws. Feem ntau, lub ib thooj ceev ntawm refractory khoom yog zoo txog rau lawv porosity thiab mineral muaj pes tsawg leeg. Hauv pob refractory, ntau dua qhov ntom ntom ntom ntom ntom ntom ntom, qhov ua tau zoo ntawm cov khoom. Qhov ntim qhov hnyav ntawm plaub hom ntawm cov khoom siv rov ua dua yog: qib qib qib alumina siab ≥ 2.5; qib thib ob qib siab alumina ≥ 2.3; qib peb qib siab alumina third 2.1.
3. Qhov pom tseeb porosity yog qhov sib piv ntawm qhov ntim ntawm qhov qhib qhov hws ntawm lub pob refractory mus rau qhov ntim tag nrho. Feem ntau, cov slag thiab cov pa phem hauv lub cub tawg corrode lub refractory pob nws tus kheej los ntawm qhov qhib qhov hws. Yog li ntawd, nws yuav tsum tau ua kom pom qhov porosity ntawm lub pob refractory me me li sai tau. Qhov pom kev porosity ntawm plaub hom ntawm cov khoom siv rov ua dua yog: qib qib-qib high-aluminium ball≤24%; qib ob-qib high-aluminium pob ≤26%; qib peb-qib qib siab alumina ≤28%.
4. Lub siab tiv taus tus nqi ntawm chav sov muaj qhov cuam tshuam loj rau kev tsim khoom, kev thauj mus los thiab siv kev ua tau zoo ntawm lub pob hluav taws xob, yog li yuav tsum muaj qhov siab tiv taus siab dua tus nqi. Chav tsev tau hais tawm hauv KN. Qhov siab tiv taus qhov tseem ceeb ntawm plaub yam ntawm cov khoom ua kom sov ntawm chav sov yog: tshwj xeeb qib siab txhuas pob ≥ 25; qib qib siab txhuas qib ≥ 15; qib thib ob qib siab txhuas ≥ 10; qib peb qib siab txhuas pob ≥ 8.
5. Lub ntsuas kub ua kom sov ntawm lub pob refractory hais txog qhov kub uas nws deforms thaum siv. Qhov hnyav ua kom sov ntawm plaub hom ntawm cov khoom siv rov ua dua yog: qib tshwj xeeb qib-aluminium pob ≥1530 ℃; qib-qib high-aluminium pob ≥1480 ℃; qib ob qib high-aluminium pob ≥1450 ℃; thiab qib peb-qib high-aluminium pob ≥1400 ℃.
6. Thermal poob siab ruaj khov yog lub peev xwm ntawm lub refractory pob los tiv thaiv qhov kub hloov pauv hauv qhov txias thiab kub sai. Txhawm rau ntsuas qhov ntsuas qhov ua tau zoo ntawm cov pob refractory, feem ntau nws tau hais tawm ntau zaus nyob rau qhov xwm txheej ntawm 1100 ℃ dej txias. Lub thermal poob siab ruaj khov ntawm plaub hom ntawm cov khoom siv refractory yog: tshwj xeeb siab alumina pob ≥ 10 zaug; thawj qib qib alumina qib siab, qib qib qib alumina siab thib ob, thiab qib peb qib siab alumina pob ≥ 15 zaug.
