Kusankhidwa Kwa Zida Zowonongeka Kwa Aluminiyamu Osungunula Ng'anjo Yamoto

Pali mitundu yambiri yaimafakitaleaaluminiummeltingfng'anjo, makamaka ng'anjo yowonetsera, ng'anjo yopangira ng'anjo, ndi zina zotero, kuwonongeka kwa ng'anjo ya ng'anjo kumakhala makamaka kulowetsa madzi a aluminiyamu ndikupukuta ndi njerwa zadongo, njerwa za alumina zowonongeka ndi miyala ya njerwa ya corundum mullite, komanso ndi zomangira za aluminiyamu zowonongeka ndi zowonongeka. pulasitiki yotchinga, chifukwa chogwiritsa ntchito zinthu zabwino, moyo wa ng'anjo ndi wautali.

Choyamba, refractories kwa chonyezimira ng'anjo, chonyezimira ng'anjo lagawidwa m'magulu ang'onoang'ono ndi tilting mtundu, ntchito gasi kapena mafuta olemera monga mafuta.Aluminiyamu smelting ndi ng'anjo ng'anjo, osagwira ntchito wosanjikiza ndi ulusi refractory anamva ndi dongo kutchinjiriza refractory njerwa zomangamanga, dziwe losungunuka pamwamba pa gawo la ntchito wosanjikiza ndi dongo njerwa zomangamanga, komanso likupezeka mkulu aluminiyamu refractory castables kapena midadada prefabricated.Kusungunuka dziwe ntchito wosanjikiza monga ntchito njira zosiyanasiyana, zinthu zake ndi osiyana, ntchito Al2O3 zili zoposa 75% ya mkulu aluminiyamu refractory njerwa zomangamanga kapena kuposa, komanso likupezeka Al2O3 zili 80% kunja mkulu zotayidwa refractory castables. kutsanulira mu wonse wosanjikiza ntchito, pamene kusungunuka mkulu-chiyero zitsulo zotayidwa, ndi kusungunuka dziwe ntchito wosanjikiza ayenera kukhala mkulu chiyero mullite njerwa, zircon njerwa kapena corundum njerwa zomangamanga.Aluminiyamu kukhetsa pakamwa, otaya aluminium thanki ndi liner yake, pofuna kukana kulowa ndi kukokoloka kwa aluminiyamu madzi, ntchito yaikulu silicon carbide njerwa zomangamanga.

Kenako ng'anjo yotenthetsera yokhala ndi zida zomangira, nthawi zambiri imakhala ndi njerwa zadongo kapena magawo atatu amiyala ya njerwa ya alumina.Pansi pa ng'anjo nthawi zina amatsanuliridwa ndi aluminiyamu yapamwamba kwambiri yokhotakhota, kenako njerwa zomangira za aluminiyamu.Pamene mphamvu ya ng'anjo yopatsidwa mphamvu ndi yocheperapo 10t, thupi lake lozungulira likhoza kupangidwa ndi aluminiyamu yapamwamba yowonongeka kapena yowonongeka ndi zinthu zomwe zili ndi Al2O3 pafupifupi 75%, ndi corundum refractory castable kapena youma vibrating zinthu ziliponso.Chovala chozungulira chozungulira cha inductorng'anjo ya aluminiyamu yosungunukaamatsanuliridwa ndi corundum refractory castables lonse.

Slot induction ng'anjo liner chipolopolo atagona 10mm asbestosi pepala kapena refractory CHIKWANGWANI, ndiyeno zomangamanga dongo matenthedwe kutchinjiriza refractory njerwa kapena bleaching njerwa kutchinjiriza wosanjikiza;ntchito wosanjikiza ndi koyilo mozungulira liner ambiri ntchito dongo refractory kusinja chuma kusinja, likupezeka dongo refractory kuthira zinthu pa malo kuthira, lalikulu kagawo kupatsidwa ulemu ng'anjo ntchito wosanjikiza, liliponso Al2O3 zili wamkulu kuposa 55% ya mkulu aluminiyamu refractory njerwa zomangamanga.

Kukana kutentha dziwe ng'anjo wosanjikiza wosagwira ntchito ndi dongo kutchinjiriza refractory njerwa, kutengeka mikanda njerwa kapena insulation mbale zomangamanga.Komanso kupezeka mu chochuluka kachulukidwe wa 0.8g/cm3 kuwala refractory castable chonse kuthira;kusungunuka dziwe ntchito wosanjikiza ntchito Al2O3 zili pafupifupi 80% ya mkulu aluminiyamu refractory njerwa zomangamanga, komanso likupezeka mu chochuluka osalimba 2.4g/cm3 mkulu aluminiyamu refractory moto castable kuthira.Zosanjikiza zomwe zili pamwamba pa dziwe losungunuka nthawi zambiri zimamangidwa ndi njerwa zadongo kapena midadada yopangidwa kale, ndipo imathanso kupukutidwa ndi pulasitiki wapamwamba wa alumina.

Pansi, khoma ndi denga la ng'anjo ya chipinda cha gasi amapangidwa.Itha kugwiritsidwanso ntchito limodzi ndi alumina reflection ng'anjo.Zida zake zopangira ng'anjo ndi njerwa zadongo komanso njerwa zazitali za alumina.

Aluminiyamu kuyenga ng'anjo ng'anjo khoma ndi magnesium njerwa zomangamanga, ena onse mbali ndi dongo njerwa ndi mkulu aluminiyamu refractory njerwa, electrolysis, kutentha ufa zambiri ndi 720-800 ℃, kutentha ntchito ndi otsika, kotero moyo utumiki wautali.
