Enwere ike kewaa brik ndị na-agba agba n’ime brik corundum-spinel ventilashion brik, corundum-chromium oxide system ventilation brik, corundum-spinel system ventilashion oche brik na corundum-chromium oxide usoro ventilashion oche brik dị ka ihe ha si dị.

1 Corundum-spinel sistem brik na -eku ume

N’ihi na nguzogide slag na nkwụsi ike nke ikpo ọkụ nke corundum castables nke otu oge adịghị mma, ihe ọkpụkpụ spinel nwere ezigbo nkwụsị nkwụsị nke slag. Ya mere, a na-agbakwunye spinel fused dị elu na nkedo corundum iji nweta nzube nke imeziwanye arụmọrụ nke corundum castable. Akụrụngwa a na-abụkarị corundum nwere ụdị efere, na brik ndị na-ekuku ikuku nke a na-agbanye n’ọkụ dị elu na ihe nkedo nwere ezigbo nguzogide ujo na nguzogide slag.

2 Corundum-Chromium Oxide Sistemu brik nwere ike iku ume

Iji mee ka ọ dịkwuo mma iguzogide nchara slag corrosion nke brik ikuku na-eme ka ikuku, a na-agbakwunye ụfọdụ chromium oxide micropowder na nhazi. Isi akụrụngwa bụ corundum yiri efere, a na-agbakwunye chromium oxide na corundum castable. Na okpomọkụ dị elu, chromium oxide na aluminum oxide na-emepụta ihe ngwọta siri ike na-ekpo ọkụ, ma n’otu oge ahụ na-emepụta ihe ngwọta siri ike MgO · Cr2O3-MgO · Al2O3 na obere ego nke magnesium oxide. Viscosity nke ngwọta siri ike a dị oke elu, na corrosion na iguzogide Fe2O3 ma ọ bụ slag na-eme ka ọ dịkwuo mma, nke mere na ntinye na corrosion nke ígwè slag nwere ike igbochi nke ọma na okpomọkụ dị elu. N’otu oge ahụ, obere Cr2O3 nwekwara ike igbochi oke ibu nke Al2O3, belata nrụgide na kristal, ma melite njirimara anụ ahụ nke ihe onwunwe. Otú ọ dị, ọ bụrụ na ọnụ ọgụgụ nke mgbakwunye dị ukwuu, a ga-egbochi uto nke mkpụrụ osisi corundum, a ga-enwekwa nchekasị n’ime, si otú ahụ na-ebelata ihe onwunwe anụ ahụ nke ihe onwunwe. Tụkwasị na nke ahụ, ọnụahịa nke Cr2O3 dị oke elu, na-agbakwụnye ihe dị ukwuu ga-eme ka ọnụ ahịa dịkwuo elu, ọ ga-enwekwa mmetụta ụfọdụ na gburugburu ebe obibi.

3 Corundum-spinel sistem iku ume oche brik

Sistemu corundum-spinel brik na-eku ume bụ ihe a na-ejikarị eme ihe, na isi akụrụngwa bụ corundum. Uru ya bụ na spinel nwere nguzogide siri ike na acids na alkalis, ma bụrụ ihe na-agbaze dị elu na arụmọrụ dị mma. Aluminom-magnesium spinel nwere nguzogide siri ike na slag alkaline, ma nwee mmetụta siri ike na ígwè oxides. Mgbe ọ na-abịa na kọntaktị na magnetite na okpomọkụ dị elu, ọ ga-emeghachi omume iji mepụta ngwọta siri ike, a pụkwara imeziwanye ihe mgbochi corrosion okpomọkụ nke brik oche na-eku ume; N’otu oge ahụ, ngwọta siri ike MgO ma ọ bụ Al2O3 spinel nwere nguzogide ujo dị mma n’ihi ọdịiche dị na ọnụọgụ mgbasawanye n’etiti mineral.

4 Corundum-Chromium Oxide Sistemu Mgbochi Na-ekute ume

A na-emepụta brik corundum-chromium oxide nke na-eku ume na-adabere na usoro corundum-spinel iji mee ka ọ dịkwuo elu okpomọkụ na-eguzogide brik oche na-eku ume. Isi akụrụngwa bụ tabular corundum, a na-agbakwunye obere ntụ ntụ chromium oxide nke ụlọ ọrụ mmepụta ihe. Uru ya bụ na na ndabere nke imeziwanye arụmọrụ nke brik site na spinel, ngwọta siri ike nke Al2O3-Cr2O3 guzobere nwere mmụba dị ịrịba ama na nguzogide corrosion na-eguzogide ígwè oxide slag. Ịgbakwunye obere Cr2O3 nwere ike igbochi oke uto nke kristal alumina, si otú ahụ belata kristal dị n’ime. Nchegbu, kwalite nguzogide ujo, nguzogide mbuze na nguzogide mbuze nke brik oche na-eku ume.
