Corundum

Ibikoresho fatizo bya corundum castable byahujwe na corundum yera, corundum yahujwe cyangwa corundum yumukara. Ntakibazo cyaba ibikoresho bibisi byakoreshwa nkigiteranyo, ibice bifite ubunini butandukanye bigomba kuvangwa mukigereranyo, hamwe na corundum coarse uduce, uduce duto hamwe nifu bigomba kuba bifite formulaire ikwiye, hanyuma bigahuzwa ninyongeramusaruro za Qihe (micropowder ya silika, kugabanya amazi na fibre idashobora guturika), igomba kongerwaho ibikoresho bibisi kandi byuzuye neza.

Imikorere y'ibicuruzwa

Ugereranije na alumina yo hejuru hamwe na mullite castable, corundum castable ifite imbaraga za mashini kandi ikarwanya kwambara, ariko guhangana nubushyuhe bwumuriro ntabwo ari byiza nka mullite castable. Ongeramo umubare munini wa mullite mubikoresho fatizo birashobora kunoza ubushyuhe bwumuriro wa corundum castable. Corundum castable ifite imbaraga zo gukomeretsa kandi zihamye zubaka. Ubushobozi bunini, corundum castable casting lining ifite uburyo bwiza bwo kurwanya ruswa, kwihanganira kwangirika, kwangirika kwinshi no kurwanya imbaraga zikomeye, ifu nisuri yubushyuhe bwo hejuru.

Itanura rya Ferrosilicon ni itanura ryamashanyarazi mu nganda rikoresha ingufu nyinshi kandi ni ubwoko bwitanura ryamazi arc. Itanura rya Ferrosilicon ririmo igikonoshwa, itanura ryitanura, itanura ryumuriro, urushundura rugufi, sisitemu yo gukonjesha amazi, sisitemu yo gukuramo umwotsi, sisitemu yo gukuraho ivumbi, igikonjo cya electrode, uburyo bwo kurekura no guterura, sisitemu yo gupakira no gupakurura, umugenzuzi, ibikoresho byaka, hydraulic sisitemu, transformateur Nibikoresho bitandukanye byamashanyarazi, nibindi, gukoresha ibikoresho bivunika nabyo birasabwa cyane.

Mu 2006, Uruganda rwacu rwashinzwe i Yuzhou, ishingiro ryibikoresho fatizo. Ubutare bunini bwa bauxite ni imvange ya colloidal ivanze neza igizwe na hydroxide ya aluminium na ratios zitandukanye. Hafi ya alumina bauxite mu nganda zikora inganda zisanzwe zerekeza ku bucukuzi bwa bauxite hamwe na Al₂O₃ ibarwa ibarwa irenga 48% hamwe na Fe₂O₃ nkeya.
