Corundum tus kheej cov khoom siv yog cov khoom lag luam siab tsim tau raws li cov khoom siv ua kua thiab daim ntawv thov ntawm cov khoom siv refractory. Corundum tus kheej cov khoom siv tau Degas thiab qib tsis muaj kev vibration los ntawm nws txoj kev sib nqus, yog li ua tiav Densification.
Corundum tus kheej cov khoom muaj cov txiaj ntsig hauv qab no: Cov kua muaj zoo thiab lub sijhawm tsim nyog tsim nyog; lab zog-txuag, nrawm thiab yooj yim; lub zog siab thiab lub neej ntev; Zoo thermal rwb thaiv tsev kev ua tau zoo, kev kub siab kuj, zoo thermal poob siab ruaj khov, yaig tsis kam thiab yaig kuj.
Corundum tus kheej cov khoom siv tuaj yeem siv tau txhua feem ntawm cov khoom noj uas tsis muaj txiv qaub ua noj, ultra-castabe, thiab cov cement-castables dawb. Corundum castables yog tsim nyog rau sau rau hauv qab ntawm lub ladle thiab ib ncig ntawm lub hauv paus cib, thiab sab saum toj ntawm cov hluav taws xob hluav taws xob; Mullite tus kheej ntws cov khoom siv thiab cov khoom siv high-aluminium tus kheej flasing yog tsim nyog rau lub tsev nyob sab hauv, cov dej txias yeeb nkab qhwv, thiab sab saum toj thiab phab ntsa ntawm cov cua sov cua sov. Tsis tas li ntawd, cov ntaub ntawv ntws rov qab los kuj tseem mechanized.
Cov ntaub ntawv tseem ceeb ntawm Corundum tus kheej cov khoom yog qhov nqaim ntawm lub kilings, thiab nws cov yam ntxwv tuaj yeem qhia tau meej. Qhov ntau ntawm tus kheej txoj kev refractory castables tau qhia saum toj no tuaj yeem siv rau kev kho cua sov. Ib qho ntxiv, qhov siab kub ntawm kev kub siab kho cov khoom siv feem ntau siv asphalt thiab cov khoom sib xyaw ua ke lossis cov khoom sib xyaw, thiab qhov tseem ceeb tshaj plaws ntawm cov khoom siv yog 5 hli.
Kev ntws tawm tus kheej ntawm Corundum tus kheej cov khoom siv tau txawv vim yog sib txawv ntawm cov sib txawv ntawm cov refractory artgregates siv. Piv txwv li, thaum 99.4% AL2O3 ntawm Fused dawb corundum, 94.5% al2o3 ntawm kev siv ntom ntom pob zeb thiab 98.9% AL22, 3.42, 3.82 thiab 3.83 feem, thaum cov khoom sib xyaw thiab cov dej ntws tau zoo ib yam, tus nqi tus kheej ntws ntawm cov Castable yog 82%, 154%, 155% thiab 157% feem. Vim tias fused alumina-raws li corundum yog ntom, nrog fused rused dawb corundum yog qis dua li ntawm peb aggregates. Thaum npaj tus kheej txoj kev refractory castables, cov ntaub ntawv nrog cov tuab tuab, tsawg tus nqi yuav tsum raug xaiv raws li kev sib sau ua ke.
