Corundum cibyog refractory cib nrog cov ntsiab lus alumina ntau dua 85%. Corundum refractory cib tau muab faib ua sintered thiab fused corundum hluav taws cib, thaum chromium corundum refractory cib yog qib siab refractory cib ua los ntawm kev ntxiv Cr2O3 rau corundum, molding ntawm qhov kub thiab txias, thiab sintering ntawm qhov kub thiab txias. Corundum refractory cib kuj tau muab faib ua fused chromium thiab sintered chromium corundum refractory cib.
Kev kub siab sib txawv
Lub refractory kuj ntawm chromium corundum bricks yog ntau tshaj 1790 degree thiab lub load softening kub yog siab tshaj 1700 degree. Qhov kev pabcuam kub ntawm corundum refractory cib yog 1600 degree. Kev kub siab ua haujlwm ntawm chromium corundum refractory cib yog zoo dua li cov ntshiab corundum hluav taws cib.
Thermal shock stability kev ua tau zoo sib txawv
Lub zog compressive ntawm corundum refractory cib yog 70-100MPa, thiab qhov kub thiab txias compressive lub zog ntawm chrome corundum cib yog ntau dua 150MPa, uas yog siab dua corundum refractory cib. Thaum lub sij hawm firing txheej txheem ntawm corundum refractory cib thiab chrome corundum hluav taws cib, Al2O3-Cr2O3 khoom tov yog tsim los ntawm particles, nruab nrab hais thiab nplua hmoov, thiab nruab nrab ntawm cov hmoov zoo thiab hmoov zoo. Cov kua nplaum yuav txuas cov khoom thiab cov hmoov zoo. Nyob rau tib lub sij hawm, lub zog ntawm refractory bricks tau zoo heev.
Sib txawv kuj rau slag yaig
Lub thermal shock stability ntawm chromium corundum refractory cib txo nrog qhov nce ntawm Cr2O3 cov ntsiab lus. Ntawd yog, qhov thermal shock stability ntawm chromium corundum cib nrog cov ntsiab lus Cr2O3 tsawg yog zoo dua li cov cib nrog cov ntsiab lus siab Cr2O3. Feem ntau, Cr2O3 cov ntsiab lus ntawm chromium corundum hluav taws cib yog nyob nruab nrab ntawm 12% thiab 20%; tshwj xeeb tshaj yog cov AKZ hom chromium corundum refractory cib tsim los ntawm kev ntxiv me me ntawm cov additives uas ua rau theem hloov tau zoo thermal shock stability.
Cov khoom siv tshuaj lom neeg sib txawv
Corundum refractory bricks raug eroded los ntawm slag, thiab cov slag yuav nkag mus rau hauv cov cib tag nrho thiab nkag mus rau saum npoo ntawm lub qhov hws ntawm cov cib, thiab cov av ntawm cov cib yuav tig xim av; chrome corundum bricks yuav luag tsis eroded los ntawm slag, thiab cov npoo ntawm lub puab qhov yog kom meej meej demarcated los ntawm slag. Kev nkag mus rau hauv lub cib yog tsawg heev. Cov tshuaj erosion thiab permeability ntawm chromium corundum refractory bricks tiv thaiv gasified slag yog zoo dua li cov corundum refractory cib.
Chrome corundum bricks yog siv nyob rau hauv iav kiln linings, molten hlau pretreatment li, khib incinerators, gasifier linings, thiab lwm yam. Corundum hluav taws cib yog siv nyob rau hauv ob sab phlu ntawm ntau yam kub-kub kilns xws li tawg thiab transforming furnaces nyob rau hauv petrochemical thiab chiv industries, steelmaking furnaces thiab blast furnaces hauv kev lag luam metallurgical. Ob yam khoom muaj lawv tus kheej zoo, tab sis chrome corundum bricks yog ntau resistant rau kub thiab corrosion dua corundum refractory cib. Corundum refractory bricks yog pheej yig dua li chrome corundum refractory cib. Thaum qhov kub thiab txias yog qhov tsim nyog, txhawm rau txo cov nqi tsim khoom, nws tseem yog ib qho kev xaiv tsim nyog xaiv corundum refractory cib siv rau hauv qhov chaw zoo thiab qhov kub thiab txias.
