Izitena zeAlumina eziPhezulu zoShishino lweNsimbi
IIMVELISO
Izitena zokujonga iAlumina ephezulu (Izitena zokujonga-imingxuma eyi-19)
Inkcazo yeZitena eziPhezulu ze-Alumina Checker
Ukuba umxholo we-Al2O3 uphezulu kune-90%, kuthiwa yi-corundum brick. Ngenxa yezibonelelo ezahlukeneyo, imigangatho yamazwe ahlukeneyo ayihambelani ngokupheleleyo. Ngokomzekelo, amazwe aseYurophu achaza ukuba umda ophantsi we-Al2O3 umxholo we-high-alumina refractories yi-42%. E-China, izitena eziphezulu ze-alumina zivame ukubhekisela kwizitena eziphikisayo kunye nomxholo we-Al2O3 ongaphezu kwe-48%. Ubukhulu becala zenziwe nge-bauxite yomgangatho ophezulu wendalo, equlethe iiminerali ezifana ne-diaspore, i-bomerite, i-kaolinite, njl njl. Udongwe oluthambileyo okanye oluthambileyo ludityaniswe kwi-clinker ephezulu ye-alumina njenge-binder ukuqala ukuxutywa kunye nokuxuba, kwaye emva koko. iyabunjwa, yomiswe, ize ekugqibeleni igxothwe. I-refractoriness yezitena eziphakamileyo ze-alumina malunga ne-1770 ℃, kunye nobushushu bokuthambisa umthwalo yi-1420 ℃-1550 ℃. Izitena eziqhelekileyo ze-alumina eziphezulu ziyi-LZ-80, i-LZ-75, i-LZ-65, i-LZ-55, i-LZ-48, njl. iziko, iziko lomlilo ovuthayo kunye ne-rotary kiln. Ukongeza, izitena eziphakamileyo ze-alumina zikwasetyenziswa ngokubanzi njengezitena zokujonga ubushushu, iiplagi zokugalela iinkqubo, izitena ze-nozzle, njl.

Ukusetyenziswa kweZitena eziPhezulu zeAlumina
Izitena eziPhezulu zeAlumina zokuHlola zisetyenziswa ikakhulu kwiziko eliqhumayo kwiziko elitshisayo kunye neziko lomlilo.
Izitena eziphezulu ze-Alumina Checker zisetyenziswa ikakhulu kwi-regenerator yezitovu ezitshisayo. Izitena eziphezulu ze-Alumina Checker ezinesakhiwo esithile kunye nemingxuma yegridi zicwangciswe ngendlela ehlelekile. Ingaphezulu kunye nezantsi kwimingxuma yezitena zokukhangela kunokuvumela igesi ukuba idlule. Ngokweemfuno zobugcisa zemimandla eyahlukeneyo yokushisa, izitena zokuhlola i-siliceous, izitena zodongwe, njl. Kwezinye izitofu ezitshisayo ezitshisayo, izitena eziphezulu ze-alumina, izitena ze-mullite, izitena ze-sillimanite, njl.
Umsebenzi wesitovu esitshisayo kukufudumeza umoya obandayo othunyelwe ngumvutheli kwisithando somlilo emoyeni oshushu, kwaye emva koko uthumele umoya oshushu kwisithando somlilo ngokusebenzisa umbhobho otshisayo wokutshisa. Isitovu somlilo esiqhumayo sinexesha lokutshisa isithando somlilo kunye nexesha lokubonelela ngomoya, kwaye amaxesha amabini okusebenza ajikeleza rhoqo. Ngethuba lokutshisa, i-gas ye-flue evuthayo evuthayo idlula emigodini yezitena ze-checker ze-hot blast furnace kwaye idlulise ukushisa kwizitena zokukhangela; ngexesha lokunikezelwa komoya, umoya obandayo ovela kwi-blower ungena kwisithando somlilo esishisayo kwaye ushushu ngezitena zokukhangela emoyeni oshushu. Ithunyelwe kwiziko lokuqhushumba ngombhobho womoya oshushu.
