2022 lebenkii corundum chrome cusub

Faa’iidooyinka alaabta: porosity hooseeyo, cufnaanta sare, xoog sare, heerkulka sare heer sare oo iska caabin ah xirtaan, iska caabin wanaagsan qabow aad u daran iyo kulayl daran, iska caabin slag wanaagsan, iyo cimri dherer wanaagsan.

sharaxaadda alaabta

Lebenkii jaban ee Chromium corundum waxaa laga soo saaray Al2O3 saafi ah iyo Cr2O3 oo ah alaabta ceeriin ee ugu muhiimsan. Marka la barbardhigo lebenkii corundum saafi ah, waxay leedahay astaamo ka wanaagsan, sida dib -u -dejin, jilicsanaanta heerkulka wax -qabadka ee culeyska saaran, xoogga dabacsanaanta, kuleylka heerkulka sare, xasilloonida mugga heerkulka sare Resistance iyo iska -caabbinta daxalka.

Lebenkii corundum ee Chrome waa lebenkii jaban ee corundum oo ay ku jireen Cr2O3. Heerkulka sare, Cr2O3 iyo Al2O3 waxay sameeyaan xal adag oo joogto ah. Sidaa darteed, waxqabadka heerkulka sare ee lebenka corundum chromium wuxuu ka fiican yahay lebenka corundum saafi ah. Lebenkii chroundum corundum ee loo adeegsaday foornada gaas -siinta ee warshadaha batroolka ayaa ah inay ahaadaan silicon hoose, bir yar, alkali hoose, daahirnimo sare, laakiin sidoo kale leh cufnaan iyo xoog badan. Lebenkii corundum ee Chrome si baaxad leh ayaa loo isticmaalaa, iyo waxa ku jira Cr2O3 inta badan waa inta u dhaxaysa 9% ilaa 15%.

lebenkii corundum chrome waxaa sidoo kale loogu yeeraa lebenkii kanaalka ee kooromium corundum-adkaysiga u adkaysta. Waa badeecad heer sare ah oo lagu dallacsiiyay suuqa sannadihii la soo dhaafay. Waxaa laga soo saaray aluminium saafi ah Al2O3 iyo oxide chromium Cr2O3 oo ah alaabta ceeriin ee ugu muhiimsan. Marka la barbardhigo lebenkii corundum ee saafiga ahaa, waxay leedahay astaamo ka wanaagsan, sida dib -u -dejin, heerkulka jilicsanaanta culayska, Awoodda dabacsanaanta, gurguurta heerkulka sare, xasiloonida mugga heerkulka sare iyo iska -caabbinta daxalka. Lebenka corundum ee Chrome waa nooc ka mid ah walxaha jaban ee heerka sare ah, oo noloshiisa adeeggu waxay gaari kartaa 10 illaa 18 bilood ka dib isticmaaleyaal badan oo rogaya.

Tababarku wuxuu muujiyey in adeegsiga joodariga kromium corundum-ka oo aad u adkaysi badan lebenka kanaalka tuubooyinka ee foornada duubista si loogu kululeeyo biilasha qaybta-weyn, is-qabqabsi sarreeya aag kasta iyo wax-soo-saarka sare, ma aha oo kaliya inuu si weyn u kordhin karo nolosha adeegga Taabashada kanaalka iyo yaraynta xidhitaanka foornada Waqtiga, kordhinta wax soo saarka, yaraynta isticmaalka qalooca iyo kharashyada dayactirka, iyo yaraynta tirada qaboojinta degdegga ah iyo kululaynta ay keento xiritaanka foornada si loo dayactiro, si nolosha guud ee foornadu u hagaagto, faa’iidooyin dhaqaale oo cadna waa la gaari karaa.
