I-Lightweight Mullite Bricks

IMIKHIQIZO

I-Lightweight Mullite Bricks 1.0

Izitini ze-mullite ezingasindi zenziwe ngezinto eziphikisayo ezisezingeni eliphakeme, ngokuya ngamandla adonsela phansi adingekayo womkhiqizo, kunezelwa izithasiselo ze-organic composite, i-vacuum extruded futhi ifakwe emazingeni okushisa aphezulu ukwenza imikhiqizo ye-mullite engasindi. Ngesisindo sayo esilula kanye nokusebenza okuhle kakhulu kokufakwa kokushisa okushisayo, izitini ze-mullite ezingasindi zisetshenziswa kakhulu kuma-lining ashisayo aphikisayo noma izendlalelo zokufakwa kwemishini ehlukahlukene yokushisa, okwenza izimo zokuthuthukisa izinga lokusebenzisa amandla emishini.

Incazelo ye-Lightweight Mullite Brick

Izinto eziphikisayo ze-alumina ephezulu ezine-mullite njengoba isigaba sekristalu esiyinhloko ngokuvamile sinokuqukethwe kwe-alumina okungu-50% -75%. Ukushisa okuphikisayo kwezitini ze-mullite engasindi kungafinyelela ngaphezu kuka-1790 ℃. Izinga lokushisa lokuqala lokuthambisa umthwalo ngu-1600-1700 ℃. Ukumelana nengcindezi yegumbi ukukhanya okungu-70-260MPa. Ukumelana nokushaqeka okuhle kokushisa. Kunezinhlobo ezimbili: izitini ze-sintered mullite nezitini ze-mullite ezihlanganisiwe.

Izitini ze-mullite ze-sintered zenziwe nge-high-alumina bauxite clinker njengento eluhlaza eyinhloko, enenani elincane lobumba noma i-bauxite eluhlaza njenge-binder, futhi iyakhiwa futhi ifakwe i-sintered. Izitini ze-mullite ezihlanganisiwe zenziwe nge-high-alumina bauxite, i-alumina yezimboni kanye nobumba oluphikisayo, ngamalahle noma izinhlayiya ezinhle ze-coke zengezwe njenge-ejenti yokunciphisa. Ngemuva kokwakhiwa, akhiqizwa ngendlela yokunciphisa i-fusion. Amakristalu e-mullite ehlanganisiwe makhulu kunalawo e-sintered mullite, futhi ukumelana nokushaqeka okushisayo kungcono kunokwemikhiqizo e-sintered. Ukusebenza kwabo okunezinga lokushisa eliphezulu ikakhulukazi kuncike kokuqukethwe kwe-alumina kanye nokufana kokusatshalaliswa kwesigaba se-mullite nengilazi.

I-high-alumina refractory material ene-mullite (3Al2O3 · 2SiO2) njengesigaba sekristalu esiyinhloko. Okuqukethwe kwe-alumina okuvamile kuphakathi kuka-65% no-75%. Ngaphandle kwe-mullite, ukwakheka kwamaminerali nakho kuqukethe inani elincane lesigaba seglasi kanye ne-quartz enokuqukethwe kwe-alumina ephansi; kanye nenani elincane le-corundum elinokuqukethwe okuphezulu kwe-alumina. Izitini ze-mullite ezilula zingasetshenziswa ngokuqondile kuma-lining okushisa aphezulu, futhi okwamanje zisetshenziswa kabanzi kuma-shuttle kilns, ama-roller kilns, ingilazi kanye nama-petrochemical kiln linings.

Amapharamitha angokwenyama namakhemikhali wezitini ze-mullite ezingasindi zimi kanje:

Izici zezitini ze-mullite ezingasindi:

I-Ferrosilicon furnace yisithando somlilo esisebenza ngogesi sezimboni esisebenzisa amandla amaningi futhi siwuhlobo lwesithando somlilo se-arc esingaphansi kwamanzi. Isithando somlilo se-Ferrosilicon sihlanganisa igobolondo lesithando somlilo, ikhava yesithando somlilo, ulayini lwesithando somlilo, inethi emfushane, isistimu yokupholisa amanzi, isistimu yokukhipha intuthu, isistimu yokukhipha uthuli, igobolondo le-electrode, ukukhishwa kwengcindezi ye-electrode kanye nesistimu yokuphakamisa, isistimu yokulayisha nokukhipha, isilawuli, idivayisi yokusha, i-hydraulic. uhlelo, i-transformer Kanye nemishini kagesi ehlukahlukene, njll., ukusetshenziswa kwezinto eziphikisayo nakho kufuna kakhulu.

Ngo-2006, imboni yethu yasungulwa e-Yuzhou, isisekelo sezinto ezingavuthiwe. I-bauxite ore ephezulu iyingxube ye-colloidal ehlukaniswe kahle eyakhiwa ama-aluminium hydroxides kanye nezilinganiso ezihlukahlukene. I-high-alumina bauxite embonini ye-refractory ngokuvamile ibhekisela ku-bauxite ore enokuqukethwe okubaliwe kwe-Al₂O₃ okukhulu kuno-48% nokuqukethwe okuphansi kwe-Fe₂O₃.

Kufakwe ku-:

Isithando somlilo esincibilikisa ingilazi isakhiwo esiphezulu sesiteshi sezitini, amapuleti okulungisa, isakhiwo esingaphezulu sehhashi lokucubungula, i-E-glass encibilikisa izitini zesithando somlilo. Iziko lomlilo, iziko lokuncibilikisa, izinto zokucwenga, izinto zokushisisa, nezinye izinto ezishisayo. Izindawo zokufaka isicelo: imboni ye-ceramic, imboni yengilazi, imboni yensimbi, imboni ye-petrochemical, imboni ye-aluminium, neminye imikhakha yezimboni.
