Ndeupi musiyano uripo pakati pezvidhinha zvevhu nematatu-nhanho epamusoro alumina zvidhinha?

Musiyano mukuru uripo pakati pezvidhinha zvevhu neakakwira-alumina zvidhinha aruminiyamu zvemukati uye huwandu hwakawanda.

Zvidhinha zvine 40-48% aruminiyamu zvemukati zvidhinha zvevhu. Zvidhinha zvevhu zvine zviratidzo zvakasiyana zveN-1, N-2, N-3, uye N-4 muyero yenyika. Mukugadzira nekushandisa, N-2, N- 3 zvidhinha zvevhu zvinoshandiswa zvakanyanya, uye zvakare zvigadzirwa zvakajairika zvinogadzirwa nevakawanda vanogadzira. Kuwanda kwehuwandu kuri pakati pe2.1-2.15. Muchiitiko cheN-1 zvidhinha zvevhu, zvimwe zviratidzo zvakakwirira kupfuura chechitatu-giredhi yakakwira alumina zvidhinha.

Zvidhinha zvine 55% aruminiyamu zvemukati zviri zvechitatu-giredhi yakakwira-alumina zvidhinha zvine huwandu hwakawanda pakati pe2.15-2.25. Parizvino, nekuda kwenzvimbo yekugadzira uye zvekushandisa, iyo aruminiyamu yezvidhinha zvevhu ingangoita 56%. Iyo aruminiyamu yezvinhu zvevhu zvidhinha muXinmi, Henan ingangoita 56%, uye kuwanda kwemuviri kuri pamusoro pe2.15. Zvakare, iyo yekupisa tembiricha yakakwira, uye kemikari indekisi haina kudzika pane yechitatu giredhi yakakwira alumina zvidhinha, asi zvakasiyana mutoro softening tembiricha.

Iyo aruminiyamu yemukati mematanho matatu epamusoro alumina zvidhinha izvozvi zvakagadzirwa ingangoita 63%, uye mamwe ane 65%. Kuwanda kwemuviri kuri pamusoro pe2.25, uye tembiricha inodzikamisa mutoro iri pasi zvishoma. Panyaya yezviratidzo zvemakemikari, zvakangosiyana neyechipiri giredhi yakakwira alumina zvidhinha muyuniti huremu uye mutoro unopfavisa tembiricha.

Iko kutaridzika kwemavara ezvitina zvevhu uye chechitatu-giredhi yakakwira-alumina zvidhinha zvichiri zvakasiyana. Zvidhinha zvevhu ndezvitsvuku-yero, uye chechitatu-giredhi yakakwira-alumina zvidhinha chena uye yero.

Pane musiyano wehuremu pakati pezvidhinha zvevhu negiredhi rechitatu alumina zvidhinha. Izvo zvakafanana zvidhinha zvevhu zvidhinha zviri kureruka kupfuura giredhi rechitatu yakakwirira alumina zvidhinha. Iyo yekupisa tembiricha zvakare yakadzika ne20-30 ° C.

Zvidhinha zvevhu uye giredhi matatu epamusoro alumina zvidhinha zvine musiyano mukumanikidza simba uye mutoro softening tembiricha. Iko kusimba kwesimba kwezvidhinha zvevhu 40Mpa, nepo simba rekumanikidza regiredhi rechitatu rakakwirira alumina zvidhinha riri 50Mpa. Mutoro wakapfava wezvidhinha zvevhu zvakare wakakwirira kupfuura uya wegiredhi rechitatu. Iyo Refractoriness yealuminium chidhinha iri 30-40 ℃, uye yayo Refractoriness inenge 30 ℃ yakaderera.
