cov khoom piav qhia

Cov khoom siv raw siv hauv cov khoom siv chromium corundum series yog cov khoom sib xyaw ua ke los ntawm kev kub kub melting ntawm alumina thiab chromium oxide nyob rau hauv ib qho kev faib ua feem.Cov khoom siv tseem ceeb yog siab bauxite (los yog muaj alumina) los ntawm kev ntxiv cov nyiaj tsim nyog ntawm chromite thiab txo nws.Tus neeg sawv cev yog melted ntawm qhov kub siab nyob rau hauv lub cub hluav taws xob, thiab cov molten chromium yog poured rau hauv pwm kom maj mam txias, thiab ces nws yog ua tom qab annealing..

Chromium corundum refractory khoom fused cam khwb cia chrnmecorundum refrac-tory tseem hu ua fused cam khwb cia chrnmecorundum refrac-tory.Lub fused cam khwb cia refractory khoom tsim los ntawm cov khoom siv ntawm alumina thiab chromium oxide thiab ib qho me me ntawm spinel, uas muaj 60% mus rau 87% ntawm alumina thiab 30% ntawm chromium oxide.Txoj kev ceev ntom yog 3.2-3.9g / CM3 ;, lub siab kub siab yog siab dua, piv nrog lwm hom kev txhim kho corundum, cov corrosion tsis kam ntawm lub iav yaj yog qhov muaj zog tshaj.Nws tuaj yeem siv los ua lub hauv ob sab phlu ntawm qhov cub uas yog nyob rau hauv kev sib cuag ncaj qha nrog lub iav molten.

Chromium corundum refractories yog dav siv nyob rau hauv lub hauv ob sab phlu ntawm thee-dej slurry pressurized gasifier, ladle refining rauv thiab carbon dub reactor hauv ob sab phlu, petrochemical kev lag luam slag gasification rauv hauv ob sab phlu thiab iav melting rauv hauv ob sab phlu, thiab kuj siv tau rau cua sov chrome. corundum platform cib rau qhov cub yog ib qho khoom siv tseem ceeb hauv kev lag luam kub.

AL203 thiab Cr2O3 yog cov qauv corundum, lub vojvoog ntawm Cr3 + yog 0.620, thiab lub vojvoog ntawm AL3 + yog 0.535.Raws li empirical formula:

Txij li qhov sib txawv ntawm Cr3 + thiab AL3 + ion radii tsawg dua 15%, Cr ions tuaj yeem hloov pauv AL nyob rau hauv AL203 lattice, tsim ib qho kev hloov pauv tsis tu ncua.

Cov qauv siv lead ua ntawm Cr203 thiab AL203 yog tib yam, thiab lub vojvoog ionic txawv ntawm 13.7%.Yog li ntawd, Cr203 thiab AL203 tuaj yeem tsim cov khoom siv tsis kawg ntawm qhov kub thiab txias.Los ntawm qhov kev xav ntawm cov kab ua kua-khoom, nrog rau qhov nce ntawm Cr203 cov ntsiab lus, qhov kub ntawm cov kua theem pib tshwm kuj nce.Yog li, ntxiv qhov tsim nyog ntawm Cr203 rau AL203 tuaj yeem txhim kho cov khoom siv kho tshuab thiab cov kev pabcuam kub kub ntawm corundum refractories.

Cr203 tuaj yeem tsim cov ntsiab lus siab melting point lossis eutectic nrog lub siab melting kub nrog ntau hom oxides.Piv txwv li, FeO·Cr203 spinel tsim los ntawm Cr203 thiab Feo muaj ib tug melting point siab li 2100 ℃;Cr203 thiab AL203 tuaj yeem tsim cov kev daws teeb meem tas mus li.Tsis tas li ntawd, Cr203 kuj tseem tuaj yeem ua kom cov viscosity ntawm cov slag thiab txo cov kua dej ntawm cov slag, yog li txo qhov corrosion ntawm slag rau refractory.Yog li ntawd, ntxiv qhov tsim nyog ntawm Cr203 rau cov khoom siv refractory tuaj yeem txo qhov kev cuam tshuam ntawm cov khoom siv hauv cov khoom siv hluav taws xob los ntawm slag yaig.Tsis muaj qhov pom tseeb tsis tu ncua ntawm qhov muaj peev xwm corrosion ntawm slag rau chromium corundum refractories thiab lub hauv paus ntawm slag.

Cov chromium corundum cib ua los ntawm cov khoom siv chromium corundum refractory yog nyob rau hauv qhov cub.Thaum lub hauv paus slag yog 2, lub chromium corundum cib muaj qhov zoo tshaj plaws tiv thaiv hlau slag corrosion;thaum lub hauv paus slag yog 0.2, qhov tob corrosion ntawm tooj liab slag rau chromium corundum cib Qhov tsawg tshaj plaws;Thaum lub hauv paus slag yog 0.35, qhov tob ntawm corrosion ntawm tin slag mus rau chrome corundum cib yog qhov tsawg tshaj plaws;Thaum cov hlau lead slag pib yog 0.3, lub thickness ntawm cov residue yog qhov loj tshaj plaws thiab qhov tob ntawm cov tshuaj tiv thaiv txheej, txheej yaig thiab txheej nkag mus yog qhov tsawg tshaj plaws.Thaum lub slag alkalinity yog 0.37, corrosion kuj ntawm chrome corundum bricks yog qhov zoo tshaj plaws.
