Refractory siab alumina bauxite yog cov khoom siv refractory feem ntau, siv dav hauv steel, cement, iav, tshuaj thiab lwm yam kev lag luam. Kab lus no yuav qhia meej txog cov khoom, kev siv thiab cov yam ntxwv ntawm siab -alumina bauxite.
Ib qho: Cov khoom ntawm siab alumina bauxite
Refractory siab alumina bauxite yog cov khoom siv refractory feem ntau yog ua los ntawm kaolin, bentonite thiab lwm yam khoom siv. Nws cov khoom tseem ceeb yog alumina thiab aluminium silicate. Nws muaj lub zog compressive siab, zoo heev kub tsis kam thiab tshuaj lom neeg ruaj khov, thiab yog cov khoom zoo heev refractory.
Lub ntsiab khoom ntawm refractory siab alumina bauxite yog raws li nram no:
1.High kub tsis kam
High - alumina bauxite muaj qhov ua haujlwm kub zoo heev thiab tuaj yeem tiv taus qhov kub thiab txias, feem ntau ncav cuag 1700℃. Yog li ntawd, nws yog cov khoom siv refractory zoo heev rau siv nyob rau hauv qhov chaw kub kub.
2. Siab compressive zog
Lub zog compressive ntawm siab - alumina bauxite kuj siab heev thiab tuaj yeem tiv taus siab loj. Qhov no yog vim nws lub cev qauv nruj heev thiab tuaj yeem tiv thaiv kev puas tsuaj los ntawm sab nraud.
3. Kev ruaj ntseg tshuaj zoo
High -alumina bauxite muaj tshuaj lom neeg ruaj khov thiab tuaj yeem nyob ruaj khov nyob rau hauv acidic thiab alkaline ib puag ncig. Nws yuav tsis raug corroded los ntawm muaj zog acids los yog alkalis thiab tsis raug rau oxidation.
Thib ob: Kev siv cov aluminium bauxite siab
Vim tias siab -alumina bauxite muaj qhov ua tau zoo thaum tshav kub kub, compressive zog thiab tshuaj stability, nws yog dav siv nyob rau hauv ntau yam khoom siv nyob rau hauv kub kub thiab corrosive ib puag ncig. Feem ntau siv hauv cov teb hauv qab no:
1. Hlau smelting
High-aluminium bauxite yog siv rau hauv steel smelting los tsim steel- ua rauv, converters thiab lwm yam khoom forging.
2. Kev tsim cov cement
Hauv cov txheej txheem tsim cov cement, siab -alumina bauxite yog siv los ua cov ntaub ntawv refractory rau kiln hau, kiln tails thiab kiln linings.
3. Kev lag luam tshuaj
High -alumina bauxite yog dav siv hauv kev lag luam tshuaj los tsim cov reactors, catalytic converters, kub exchangers thiab lwm yam khoom siv.
4. Glass manufacturing
High- alumina bauxite kuj yog ib qho khoom siv tsis tau hauv cov txheej txheem iav. Nws tuaj yeem ua iav kilns, rwb thaiv tsev panels, thiab lwm yam.
Peb: Cov yam ntxwv ntawm siab - alumina bauxite refractory cov ntaub ntawv
High- alumina bauxite muaj cov yam ntxwv tseem ceeb hauv qab no:
1. Muaj zog tiv thaiv tshav kub
High -alumina bauxite yog kub heev- tiv taus thiab tuaj yeem tiv taus qhov kub thiab txias. Qhov no ua rau nws zoo tagnrho rau siv ntau yam khoom siv nyob rau hauv qhov kub thiab txias thiab corrosive ib puag ncig.
2.Excellent compressive zog
High- alumina bauxite muaj lub zog compressive siab heev thiab tuaj yeem tiv taus qhov siab loj, uas ua rau nws lub neej ua haujlwm ntev.
3. Zoo corrosion kuj
High -alumina bauxite muaj tshuaj lom neeg ruaj khov thiab tuaj yeem nyob ruaj khov nyob rau hauv acidic thiab alkaline ib puag ncig. Nws yuav tsis raug corroded los ntawm muaj zog acids los yog alkalis thiab tsis raug rau oxidation.
4. zoo heev antioxidant zog
Refractory siab alumina bauxite muaj oxidation zoo thiab tuaj yeem tiv taus oxidation ntawm qhov kub thiab txias.
5. Cov txheej txheem yooj yim dua
High-alumina bauxite yog qhov muag muag thiab tuaj yeem ua tau yooj yim rau hauv ntau yam duab, ua rau nws yooj yim rau siv.
