Amabhola e-alumina aphikisayo anekhwalithi enhle yamandla aphezulu, ubulukhuni obuphezulu, ikhono elihle kakhulu lokuhuzuka, ukujiya okukhulu, ukusebenza kwezinga lokushisa eliphezulu, ukumelana nokugqwala, ukungcola okuncane kanye nezinye izakhiwo ezinhle kakhulu. Amabhola e-alumina asetshenziswe kabanzi ekuqedeni nasekucubunguleni ngokujulile izinhlobo ezahlukene ze-ceramic, enamel, ingilazi, amakhemikhali kanye nezinye izinto ezijiyile neziqinile.
Izakhiwo zamabhola e-Alumina Refractory
- Ukumelana Nokushisa Okuphezulu
- Ukumelana Nokushisa Okuhle
- Amandla Aphezulu Okusebenza Kwemishini
- Impilo Ende Yenkonzo
Ukwakheka kwamabhola e-Alumina Refractory
Amabhola e-Alumina acwebezelayo enziwe nge-AL2O3, i-kaolin, i-synthetic aggregate, i-mullite crystal nezinye izinto. Ngokwendlela yokugoqa kanye ne-press molding, amabhola e-aluminium acwebezelayo anezinzuzo zamandla aphezulu, ukumelana okuhle nokushaqeka kokushisa, ukushintshwa kanye nokuhlanza okulula, impilo ende yenkonzo njalo njalo.
Inqubo Yamabhola Angaphendukiyo e-Alumina
Ukuze kwenziwe amabhola e-alumina aphikisayo, i-electrode ibekwa phansi kwe-graphite crucible, futhi i-arc ingaqalwa ngokungeza inani elithile le-industrial alumina powder. Ukusebenza kwamanje okungu-1.0kA, i-voltage engu-80 ~ 100V. Ngemva kokushaya, njengoba i-Al2O3 incibilika, ilayisha kancane kancane, kuze kube yilapho uketshezi lwezinto lugcwala nge-graphite crucible, izinga lokushisa loketshezi lwezinto ezibonakalayo lingu-2200 ~ 2300 ℃. Ngemva kwalokho, i-crucible iyathululwa bese ikhambi liphuma.

Ukusetshenziswa kwamabhola e-Alumina Refractory
Amabhola okujikisa e-Alumina asetshenziswe kabanzi ekuqedeni nasekucubunguleni ngokujulile izinhlobo ezahlukene ze-ceramic, enamel, ingilazi, amakhemikhali nezinye izinto eziqinile neziqinile. Ikakhulukazi amabhola okujikisa e-aluminium afanelekela imishini yokuhlukanisa umoya kanye nesithando sensimbi esivuthayo sesithando somlilo njengesithando sokushisa igesi njengesithasiselo sokugcina ukushisa.
