Kunezinhlobo eziningiiizimboniai-aluminiummeltingfumbhobho, ikakhulukazi isithando somlilo esikhanyayo, isithando somlilo sokungeniswa, njll., ukucekelwa phansi kwesithando somlilo ngokuyinhloko ukungena koketshezi lwe-aluminium nokukhuhla ulwelwesi lwayo ngezitini zobumba, izitini eziphakeme ze-alumina eziphikisayo kanye nokwakhiwa kwezitini ze-corundum mullite, kodwa futhi nezinsimbi eziphezulu ze-alumina refractory kanye i-plastic refractory lining, ngenxa yokusetshenziswa kwezimo ezinhle, impilo yesithando somlilo yinde.
Okokuqala, ama-refractories wesithando somlilo esikhanyayo, isithando somlilo esikhanyayo sihlukaniswe ngohlobo olungaguquki nolutshekile, kusetshenziswa igesi noma uwoyela osindayo njengophethiloli.Ukuncibilikiswa kwe-aluminium kuyisithando somlilo esingaguquki esikhanyayo, ungqimba olungasebenzi olune-fiber refractory ezwakalayo kanye ne-clay insulation refractory masonry yezitini, ichibi elincibilikisiwe elingaphezu kwengxenye yongqimba olusebenza ngezitini zobumba, kodwa futhi kuyatholakala okuphonswa kwe-alumina ephezulu kwe-refractory noma amabhlogo asenziwe ngaphambilini.I-Melting pool work layer ngokusho kokusetshenziswa kwamasu ahlukene, impahla yayo ihlukile futhi, isebenzisa okuqukethwe kwe-Al2O3 okungaphezu kuka-75% we-alumina ephezulu ye-refractory masonry yezitini noma ngaphezulu, kodwa futhi iyatholakala nokuqukethwe kwe-Al2O3 kwe-80% ngaphandle kwe-aluminium ephezulu ye-refractory castables. ithululelwa ongqimbeni lomsebenzi jikelele, lapho kuncibilika i-aluminium yensimbi ehlanzekile, ungqimba lomsebenzi wechibi elincibilikayo kufanele lube isitini se-mullite sokuhlanzeka okuphezulu, isitini se-zircon noma ukwakhiwa kwezitini ze-corundum.Umlomo okhipha i-aluminium, ithangi le-aluminium eligelezayo kanye nomugqa walo, ukuze umelane nokungena nokuguguleka koketshezi lwe-aluminium, kusetshenziswa ukwakhiwa kwezitini ezinkulu ze-silicon carbide.
Bese kuba isithando somlilo esingeniswayo esinezinto eziphikisayo, ngokuvamile ngezitini zobumba noma amaleveli amathathu okwakhiwa kwezitini eziphikisayo ze-alumina.Ngaphansi kwesithando somlilo ngezinye izikhathi kuthelwa ngezinsimbi eziphezulu ze-alumina refractory kuqala, bese kuba izitini eziphezulu ze-alumina refractory.Lapho umthamo wesithando somlilo sokungeniswa ungaphansi kwe-10t, umzimba wayo wolwelwesi ungenziwa nge-alumina ephezulu ekwazi ukuphonswa noma into eshaya ngamandla enokuqukethwe kwe-Al2O3 okungaba ngu-75%, futhi i-corundum refractory castable or dry vibrating material iyatholakala.I-liner ezungeze ikhoyili ye-inductor yeisithando somlilo se-aluminiumithululelwa nge-corundum refractory castables iyonke.
Igobolondo le-slot lener ye-slot lener ebeka ishidi le-asbestos elingu-10mm noma i-fiber refractory ezwakalayo, bese kuba ubumba lwamatshe okushisa izitini eziphikisayo noma isitini sobuhlalu sobuhlalu ukuze kufakwe ungqimba;ungqimba lomsebenzi nekhoyili ezungeze ulayini ovame ukusetshenziswa ubumba oluphikisayo olushaya ngamandla, lutholakala futhi i-clay refractory ethela izinto endaweni yokuthulula, ungqimba olukhulu lomsebenzi wesithando sokungeniswa kwesithando somlilo, futhi kuyatholakala okuqukethwe kwe-Al2O3 okukhulu kuno-55% we-alumina ephezulu ye-refractory masonry yezitini.
Isithando somlilo sechibi lokumelana nokumelana nongqimba olungasebenzi olunobumba lwezitini eziphikisayo, izitini zobuhlalu obukhukhulekayo noma ipuleti lokufaka amatshe.Iyatholakala futhi ngobuningi bokuminyana okungu-0.8g/cm3 ukukhanya okukhanyelayo okuphonswa kokuphonswa okuphelele;ungqimba olusebenzayo lwechibi elincibilikisiwe lisebenzisa i-Al2O3 yokuqukethwe okungaba ngu-80% wezitini eziphezulu ze-alumina refractory, kodwa futhi iyatholakala kubuningi bokuminyana obungu-2.4g/cm3 i-alumina ephezulu ephikisayo yokuthululwa komlilo.Isendlalelo esisebenzayo esingenhla kwechibi elincibilikayo ngokuvamile senziwa ngezitini zobumba noma amabhulokhi akhiwe ngaphambili angakhonjwayo, futhi singagxotshwa ngepulasitiki ephezulu ephikisayo ye-alumina.
Iphansi, udonga nophahla lwesithando somlilo segumbi legesi kwakhiwa.Ingasetshenziswa futhi ngokuhlanganyela nesithando somlilo se-alumina.Indwangu yayo yesithando somlilo iyisitena sobumba kanye nezitini eziphezulu ze-alumina refractory.
I-aluminium yokucwenga isithando somlilo odongeni nge-magnesium brick masonry, ezinye izingxenye ezinezitini zobumba nezitini eziphezulu ze-alumina refractory, i-electrolysis, izinga lokushisa lomkhumbi ngokuvamile liyi-720-800 ℃, izinga lokushisa lokusebenza liphansi, ngakho-ke impilo yesevisi yinde.
