Izitini ezijwayelekile eziphikisayo:Uma ucabangela intengo kuphela, ungakhetha izitini ezivamile ezishibhile, njengezitini zobumba.Lesi sitini sishibhile.Isitini sibiza kuphela u-$0.5~0.7/block.Inezinhlobonhlobo zokusetshenziswa.Nokho, ingabe ilungele ukusetshenziswa?Ngokuqondene nezidingo, uma kungahlangatshezwana nazo, kungase kubangele ukugcinwa njalo ngenxa yokuguga, futhi kungase kungakwazi ukusetshenziswa ngendlela evamile.Ukunakekelwa okuphindaphindiwe kungase kuholele ekulungisweni kusenesikhathi ngisho nokulimala kwemishini, okungafanele inzuzo.
Izitini zobumba ziyizinto ezineasidi ebuthakathaka, ezinomzimba ocishe ube ngu-2.15g/cm3 kanye nokuqukethwe kwe-alumina okungu-≤45%.Nakuba i-refractoriness iphezulu njengo-1670-1750C, isetshenziswa kakhulu ezingeni lokushisa eliphezulu lika-1400C.Lo mkhiqizo ungasetshenziswa kuphela ngokuhambisana nezidingo.Izinga lokushisa, ezinye izingxenye ezingabalulekile, izinga lokushisa elivamile lamandla okucindezela izitini zobumba aliphezulu, kuphela i-15-30MPa, lezi zihlobene nezinkomba zomkhiqizo, okuyisizathu sokuthi kungani izitini zobumba zishibhile.
Izitini eziphezulu ze-alumina refractory:Izitini eziphakeme ze-alumina zinamabanga amane asekelwe ku-alumina.Ngenxa yokuthi okuqukethwe kwe-aluminium kwezinto zokusetshenziswa kuphakeme kunezitini zobumba, igama lezitini eziphezulu ze-alumina livela kulokhu.Ngokusho kwebanga, lo mkhiqizo ungasetshenziswa ezingeni lokushisa eliphezulu lika-1420 kuya ku-1550 ° C.Uma isetshenziswa, ingavezwa emlilweni.Amandla okucindezela okushisa avamile afinyelela ku-50-80MPa.Uma kuvezwa amalangabi, izinga lokushisa elingaphezulu alikwazi ukuba ngaphezu kwezinga lokushisa lokusebenza.Lokhu kuthinteka kakhulu ukuminyana komkhiqizo kanye nokuqukethwe kwe-alumina.
Izitini ze-Mullite:Izitini ze-Mullite refractory zine-refractoriness ephezulu kanye nezinga lokushisa eliphezulu lokusebenza.Zitholakala ngezinhlobo ezinzima nezilula.Izitini ezinzima ze-mullite zihlanganisa izitini ze-mullite ezihlanganisiwe nezitini ze-mullite ezihlanganisiwe.Ukumelana nokushaqeka kwe-Thermal komkhiqizo kuhle;Imikhiqizo engasindi inomphumela omuhle wokushisisa ukushisa.Imikhiqizo engasindi yilena: JM23, JM25, JM26, JM27, JM28, JM30, JM32.Imikhiqizo yochungechunge lwe-mullite engasindi ingavezwa amalangabi, futhi ama-pores asatshalaliswa ngokulinganayo Ngokusho kwamandla adonsela phansi athile kanye nokuqukethwe kwempahla eluhlaza yomkhiqizo, i-JM23 ingasetshenziswa ngaphansi kwe-1260 degrees, i-JM26 ngaphansi kwe-1350 degrees, futhi i-JM30 ingasetshenziswa izinga lokushisa eliphezulu lika-1650 degrees.Lesi futhi isizathu sokuthi kungani izitini ze-mullite zibiza.
Isitini se-Corundum:Isitini se-Corundum yisitini esiphikisayo sezinga eliphezulu esinokuqukethwe kwe-alumina engaphezu kuka-90%.Lo mkhiqizo futhi unemikhiqizo ye-sintered nehlanganisiwe.Ngokusho kwezinto zokusetshenziswa, imikhiqizo ihlanganisa: isitini se-zirconium corundum esihlanganisiwe (AZS, isitini esihlanganisiwe), isitini se-chromium corundum, njll. Amandla okucindezela okushisa avamile makhulu kuno-100MPa futhi angasetshenziswa isikhathi eside endaweni yokushisa ephezulu. ye-1,700 degrees.Intengo yalesi sitini esiphikisayo iyahlukahluka kusukela ezinkulungwaneni ezimbalwa kuya emashumini ezinkulungwane zamayuan ngethani ngenxa yezinto ezifana nenqubo yokukhiqiza kanye nokuqukethwe kwempahla eluhlaza.
Izitini zebhola ze-Alumina ezingenalutho:Izitini zebhola le-alumina ezingenalutho ziyizitini zokufaka ezilula ezingasindi uma kuqhathaniswa, zibiza cishe u-RMB 10,000 ngethani.Ngenxa yezindawo ezihlukene zokusetshenziswa nezinqubo zokukhiqiza, okuhlanganisa okuqukethwe kwe-alumina, njll., intengo yomkhiqizo kufanele ibe phezulu., njengoba kusho, inani lemali.
Okungenhla kuyisethulo sokuminyana, ukumelana nokushisa okuphezulu kanye nentengo yezitini eziphikisayo.Ngokuvamile, ukuminyana kwevolumu yezinto eziphikisayo kukalwa ngaphambi kokuphuma embonini.Ukuminyana kwevolumu: kubonisa isilinganiso sesisindo somkhiqizo owomile kumthamo wawo wonke, ovezwa ngo-g/cm3.
