Chrome Corundum Ciblub siab - Kev ua haujlwm refractory cov ntaub ntawv paub txog lawv qhov kev phom sij kub, thiab cua sov {aluminium xide thiab 10-25% chromium oxide, thiab kuj tseem muaj Tsawg tus nqi ntawm cov impurities xws li silicon oxide thiab hlau oxide. Lawv cov microstructure muaj cov corundum muaju, chromite spinel, thiab ib qho me me ntawm lub khob iav. Tus qauv no muaj cov khoom siv no muab cov khoom siv nrog cov khoom siv tau zoo heev.
Cov txheej txheem ntau lawm
Cov txheej txheem ntau lawm ntawm chrome - corundum cib feem ntau cuam tshuam nrog cov kauj ruam tseem ceeb no:
Khoom npaj
1) .Ynusizing elecorfused chrome corundum cov khoom siv: uas siv cov roj ntsha txhuas oxide thiab chromium} {}}), tom qab ntawd yuav khoom hauv granules.
2)
01
Cov Khoom Siv Hluav Taws Xob
Raws li cov kev xav tau ua tau zoo, cov khoom sib txawv ntawm cov khoom siv chrome, thiab lwm yam ntxiv, muab cov roj ntsha, thiab lwm yam.
02
Binder ntxiv
Cov phau ntawv xaiv (piv txwv li, phosphoric acid, monumina- chromium oxide sol, thiab lwm yam. Stokred. Cov sib tov feem ntau yog sab laug rau hnub nyoog rau ib lub sijhawm (piv txwv li, ntau dua lossis sib luag rau 24 teev) kom muaj kev nkag mus rau qhov kev nkag mus thiab hnov.
03
Nias thiab shaping
Cov khoom siv tsis sib xyaw cov khoom siv tau nias rau hauv cov av zom zaws hauv qab siab.
04
High - sov kub
Cov kab xev pob zeb tawg tau raug rho tawm hauv qhov siab -} kub kiln, feem ntau nyob rau ntawm 1600℃rau 1700 degree, lossis siab dua. Raws li qhov kub thiab txias, nyuaj ntawm lub cev thiab tshuaj lom neeg tshwm sim hauv cov khoom siv raw, tsim cov khoom lag luam tuab uas imparts cov khoom xav tau rau cov chromium corundum cib.

Kev ua txuj ua rau cov chromium corundum cib
Vim yog lawv cov khoom tshwj xeeb thiab lub cev, corundum refractory cib extel hauv kev muaj mob hnyav:
Siab ntev
Kev pabcuam kub tuaj yeem ncav cuag 1800-1900 degree, nrog rau thauj softening kub feem ntau saum 1700 degree.
01
Zoo heev corrosion
Tshwj xeeb tsis kam rau Molten Slag, iav yaj, thiab cov tshuaj yauv tshuaj lom neeg. Slag tsis kam nce ntxiv nrog cov ntsiab lus cr₂o₃ siab dua.
02
Zoo thermal poob siab loj
Muaj peev xwm tiv thaiv qhov kub txias hloov yam tsis muaj kev tawg los yog spalling, txuas ntxiv lawv lub neej pabcuam. Ntxiv cov bauxite, Andalusite, thiab lwm yam, tuaj yeem txhim kho lawv cov cua sov kom ruaj khov.
03
Siab zog thiab qhov ceev
Possess high strength at both room and high temperatures, Cold crushing strength >80 MPA.
04
Cov Khoom Zoo Kuj
Nrog rau cov antionziv anti - scouring thiab anti -} spalling cov khoom, lub neej pabcuam txuas ntxiv.
05
Siab ceev thiab zoo ntim ruaj khov
Muaj cov qauv ntom ntom, tsis yooj yim ntsws lossis nthuav dav ntawm cov hluav taws xob ntau, ua kom muaj kev sib zog sib zog ntawm cov cua sov thaum siab nrog qhov ruaj khov kho.
06
Oxidation / reduction kuj
Cr₂o₃ tseem nyob ruaj khov nyob rau hauv ob oxidizing thiab txo cov cua nab kuab.
07
Cov ntawv thov ntawm Chromium Refractory Cib
Vim yog lawv cov yam ntxwv tshwj xeeb thiab cov khoom lag luam zoo tshaj plaws, chrome refractory tau siv dav hauv ntau qhov siab ntawm ntau - cov tshuab hluav taws xob kub thiab txias.
Metallurgy:
1). Hlau hlau metallurgy: ladle slag kab, rauv taws ua kom huv si, cov ntaub pua sib xyaw ntawm cov chaw ua kom haum rau cov chaw nyob hauv cov hlau sib chwv nrog Molten hlau.
2) .non- ferrous hlau smelting rhuab: npib tsib xee, txhuas, zinc, thiab aluminium smelting rauv. They effectively resist the corrosion of complex slags containing Fe₂O₃-SiO₂-CaO, significantly extending the service life of the furnace lining.
Iav Kev Lag Luam:
1) .Glass Melting Furnaces: Qhov tseem ceeb ntawm iav Melting Furneraces, Chrome urructions}} aphion iav tsis ua rau discoloration ntawm lub khob.
2)
Petrochemical Kev Lag Luam:Cov kab rau petrochemical gasifiers, tawg nthe rauv, cua sov cov cua sov, tshwj xeeb yog haum rau kev tawm tsam Molten Coal Slag yaig.
Ib puag ncig thiab kev phom sij tsis zoo:Siv nyob rau hauv cov khib nyiab phom sij thiab volatilization kilns, tiv taus tshuaj corrosion thiab siab - kub scouring.
CEMEN kev lag luam:Qeeb Miln Transpition aones, hlawv cov aav.
Sulphur rov qab cov pa roj acid roj teeb:Muaj peev xwm tiv taus acidic corrosion tshwm sim los ntawm sulphur -}}}}}} хs cov khoom siv hlau thiab nce cov khoom siv txuas mus ncig ua haujlwm.
Ntim thiab xa cov chrome corundum cib
1. Ntim rau ntawm cov ntoo pallets nrog noo noo - Cov ntaub ntawv ua yeeb yaj kiab kom tiv thaiv kev puas tsuaj.
2. ntaub ntim ntawm lub thawv ntoo.
