Amacandelo aphambili ezinto eziphikisayo ezifana izitena eziphefumlayo, izitena zebhlokhi yombhobho, kunye nezinto eziphoswayo

Izinto ezichasayo zisetyenziswa ngokubanzi kwi-metallurgy, iteknoloji yeekhemikhali, i-petroleum kunye ne-petrochemical, ukuveliswa koomatshini, ukusetyenzwa kwamandla kunye nezinye iindawo zoshishino, apho isixa esikhulu sisetyenziswa kwishishini lesinyithi. Kwiileyile zetsimbi kunye neziko lokucoca kwishishini le-steelmaking, izinto eziphikisayo ezisetyenziswa ngokuqhelekileyo ngabavelisi bentsimbi ziquka izitena eziphefumulayo, izitena ze-nozzle block, izikhuselo zombane zombane, i-castables, isanti ye-drainage, izitena ze-carbon magnesia, njl. amacandelo aphambili kunye neenxalenye ezongeziweyo zahluke kakhulu. Ukususela kuhlalutyo lweekhemikhali, izinto eziphikisayo zenziwe ngamaminerali, njenge-corundum, i-mullite, i-magnesia, njl.

(Umfanekiso) Corundum

Ngokuphathelele icandelo eliphambili lezinto ezichasayo, licandelo le-matrix elibandakanya ipropathi ye-refractory, isiseko seempawu ze-refractory, kwaye inquma ngokuthe ngqo iipropati zeemveliso ezichasayo. Ngokomzekelo, izitena eziphefumulayo kufuneka zenziwe nge-ore ephezulu, kwaye emva koko zenziwe ngeenkqubo eziqinileyo kunye nezifanelekileyo, ukwenzela ukuba kuqinisekiswe ukuba ixesha lokuphila kwezitena eziphefumulayo ezisetyenziswa ngabavelisi bensimbi banokuhlangabezana neemfuno. Iinqununu eziphambili zezinto eziphikisayo zingaba yi-oxides (i-aluminium oxide, i-magnesium oxide, njl.), okanye izinto okanye i-non-oxide compounds (i-carbon, i-silicon carbide, njl.).

Ngokobume bamacandelo aphambili, izinto eziphikisayo zinokwahlulwa zibe ngamacandelo amathathu: i-asidi, ingathathi hlangothi, kunye ne-alkaline. Izinto ezikwaziyo ukumelana ne-Acidic zizinto eziqulethe ii-acidic oxides ezifana ne-silicon oxide. Icandelo eliphambili li-asilicic acid okanye i-aluminium silicate, eya kuvelisa i-salts phantsi kwesenzo sokushisa okuphezulu kunye ne-alkali. Amacandelo eekhemikhali eziphambili ze-alkaline refractories yi-magnesium oxide, i-calcium oxide, njl. I-refractories engathathi hlangothi ngokungqongqo i-carbonaceous kunye ne-chromium refractories. Ukongezelela, ii-refractories eziphezulu ze-aluminium (umxholo we-alumina omkhulu kune-45%) zi-refractories ezingathathi hlangothi ezivame ukuba ne-acidic, ngelixa i-chromium refractories ivame ukuba ne-alkaline. Kwizinto ezichaseneyo ezingathathi hlangothi, izinto eziqhelekileyo ezixhaphakileyo ze-alumina eziphezulu ziquka izitena eziphefumulayo, izitena zebhlokhi ye-nozzle, kunye nezikhuselo zombane zombane.

(Umfanekiso) Isigqubuthelo seziko

Inkampani yethu ineminyaka eyi-18 yophando kunye nophuhliso, imveliso kunye nokuthengiswa kwezinto eziphikisayo ezifana nezitena eziphefumulayo, izitena zebhlokhi ye-nozzle, i-castables, kunye neefomyula ezinelungelo elilodwa lomenzi, uyilo olulodwa, kunye nokuphunyezwa okungqongqo kunye nomgangatho wenkqubo nganye, ukwenzela ukuba abavelisi bentsimbi banokuzisebenzisa. ngoxolo lwengqondo kunye nentuthuzelo.
