2019 Ikhwalithi Enhle Epinki/Ruby Ehlanganisiwe Ye-Aluminium Oxide

Siyaqiniseka ukuthi ngezinhlelo ezihlanganyelwe, ibhizinisi eliphakathi kwethu lizosilethela izinzuzo ezifanayo.Singakuqinisekisa kalula ukuthi uthengisa ngekhwalithi enhle kanye nenani elinolaka lika-2019 Ikhwalithi Enhle Epinki/Ruby Fused Aluminium Oxide, Samukela ithemba lokwenza ibhizinisi nawe futhi sithemba ukujabulela ukunamathisela imininingwane eyengeziwe yezinto zethu.
Siyaqiniseka ukuthi ngezinhlelo ezihlanganyelwe, ibhizinisi eliphakathi kwethu lizosilethela izinzuzo ezifanayo.Singakuqinisekisa kalula ukuthi uthengisa ngekhwalithi enhle kanye nethegi yamanani anolakaI-China Pink Fused Alumina neChromic Corundum, Izinga elihle kakhulu livela ekubambeleleni kwethu kuyo yonke imininingwane, futhi ukwaneliseka kwamakhasimende kuvela ekuzinikezeleni kwethu okuqotho.Ngokuthembela kubuchwepheshe obuthuthukisiwe kanye nedumela lemboni lokubambisana okuhle, sizama konke okusemandleni ethu ukuletha izinto ezisezingeni eliphezulu namasevisi kumakhasimende ethu, futhi sonke sizimisele ukuqinisa ukuhwebelana namakhasimende asekhaya nawangaphandle kanye nokubambisana okuqotho, ukuze sakhe ikusasa elingcono.

incazelo yomkhiqizo

Izinto ezingavuthiwe ezisetshenziswa emikhiqizweni yochungechunge lwe-chromium corundum yisixazululo esiqinile esihlanganiswe ukuncibilika kwezinga lokushisa eliphezulu kwe-alumina ne-chromium oxide ngengxenye ethile.Impahla eluhlaza eyinhloko i-bauxite ephezulu (noma i-alumina yezimboni) ngokwengeza inani elifanele le-chromite nokulinciphisa.I-ejenti iyancibilika ekushiseni okuphezulu esithandweni sikagesi, bese i-chromium encibilikisiwe ithululelwa esibunjeni ukuze ipholiswe kancane, bese yenziwa ngemva kokuhushulwa..

Imikhiqizo ye-Chromium corundum refractory ehlanganisiwe ye-chrnmecorundum refrac-tory ibizwa nangokuthi i-fused cast chrnmecorundum refrac-tory.Umkhiqizo ohlanganisiwe we-refractory owenziwe ngesisombululo esiqinile se-alumina ne-chromium oxide kanye nenani elincane le-spinel, eliqukethe u-60% kuya ku-87% we-alumina kanye no-30% we-chromium oxide.Ukuminyana kwenqwaba kungu-3.2-3.9g/cm3;, amandla okushisa aphezulu aphezulu, uma kuqhathaniswa nezinye izinhlobo ze-corundum refractories, ukumelana nokugqwala kwe-glass melt kunamandla kakhulu.Ingasetshenziswa njengolwelwesi lweziko oluthintana ngqo nengilazi encibilikisiwe.

I-Chromium corundum refractories isetshenziswa kakhulu olwelweni lwegesi yamalahle e-slurry pressurized gasifier, ladle refining furnace kanye ne-carbon black reactor lining, imboni ye-petrochemical imboni ye-slag gasification ulayini wesithando somlilo kanye nengilazi encibilika isithando somlilo, njll., futhi ingasetshenziselwa ukufudumeza I-chrome Isitini seplatifomu ye-corundum yesithando somlilo siyinto ebaluleke kakhulu embonini yokushisa okuphezulu.

I-AL203 ne-Cr2O3 ingeyesakhiwo se-corundum, irediyasi ye-Cr3+ ingu-0.620, kanti irediyasi ye-AL3+ ingu-0.535.Ngokusho kwefomula ye-empirical:

Njengoba umehluko phakathi kwe-Cr3+ ne-AL3+ ion radii ungaphansi kuka-15%, ama-Cr ions angashintsha ngokuqhubekayo nangokungenamkhawulo esikhundleni se-AL ku-AL203 lattice, enze isixazululo esiqinile esiqhubekayo esingenasiphelo.

Isakhiwo sekristalu se-Cr203 ne-AL203 ziyefana, futhi i-ionic radius ihluka ngo-13.7%.Ngakho-ke, i-Cr203 ne-AL203 zingakha isixazululo esiqinile esingapheli ezingeni lokushisa eliphezulu.Ngokombono womugqa wesigaba soketshezi oluqinile, ngokukhuphuka kokuqukethwe kwe-Cr203, izinga lokushisa lapho isigaba soketshezi siqala ukubonakala nalo liyakhuphuka.Ngakho-ke, ukungeza inani elifanele le-Cr203 ku-AL203 kungathuthukisa kakhulu izakhiwo zemishini kanye nokusebenza kwesevisi yezinga eliphezulu lokushisa kwama-corundum refractories.

I-Cr203 ingenza indawo ephezulu yokuncibilika noma i-eutectic enezinga lokushisa eliphakeme lokuncibilika elinama-oxide amaningi avamile.Isibonelo, i-FeO·Cr203 spinel ekhiqizwe i-Cr203 futhi i-Feo inendawo yokuncibilika efinyelela ku-2100℃;I-Cr203 ne-AL203 zingakha isixazululo esiqinile esiqhubekayo.Ngaphezu kwalokho, i-Cr203 ingaphinda ikhulise kakhulu i-viscosity ye-slag futhi inciphise ukugeleza kwe-slag, ngaleyo ndlela yehlise ukugqwala kwe-slag ku-refractory.Ngakho-ke, ukwengeza inani elifanele le-Cr203 kokokusebenza okuyizibazi kunganciphisa kakhulu ukuchitheka kwesakhiwo kolayini lwesithando somlilo okubangelwa ukuguguleka kwe-slag.Akukho ukujwayela okusobala phakathi kwekhono lokugqwala le-slag kuya ku-chromium corundum refractories kanye nokuyisisekelo kwe-slag.

Isitini se-chromium corundum esenziwe ngezinto eziphikisayo ze-chromium corundum sisezithandweni.Lapho isisekelo se-slag singu-2, isitini se-chromium corundum sinokumelana okungcono kakhulu nokugqwala kwe-iron slag;lapho isisekelo se-slag singu-0.2, ukugqwala kwe-slag yethusi kuya kusitini se-chromium corundum Okuncane kakhulu;lapho isisekelo se-slag singu-0.35, ukugqwala kwe-tin slag kusitini se-chrome corundum kuncane kakhulu;lapho isisekelo se-lead slag singu-0.3, ubukhulu bensalela bukhulu kakhulu futhi ukujula kongqimba lokusabela, ungqimba lokuguguleka kanye nongqimba lokungena luncane kakhulu.Uma i-slag alkalinity ingu-0.37, ukumelana nokugqwala kwezitini ze-chrome corundum kungcono kakhulu.

Siyaqiniseka ukuthi ngezinhlelo ezihlanganyelwe, ibhizinisi eliphakathi kwethu lizosilethela izinzuzo ezifanayo.Singakuqinisekisa kalula ukuthi uthengisa ngekhwalithi enhle kanye nenani elinolaka lika-2019 Ikhwalithi Enhle Epinki/Ruby Fused Aluminium Oxide, Samukela ithemba lokwenza ibhizinisi nawe futhi sithemba ukujabulela ukunamathisela imininingwane eyengeziwe yezinto zethu.
2019 Ikhwalithi EnhleI-China Pink Fused Alumina neChromic Corundum, Izinga elihle kakhulu livela ekubambeleleni kwethu kuyo yonke imininingwane, futhi ukwaneliseka kwamakhasimende kuvela ekuzinikezeleni kwethu okuqotho.Ngokuthembela kubuchwepheshe obuthuthukisiwe kanye nedumela lemboni lokubambisana okuhle, sizama konke okusemandleni ethu ukuletha izinto ezisezingeni eliphezulu namasevisi kumakhasimende ethu, futhi sonke sizimisele ukuqinisa ukuhwebelana namakhasimende asekhaya nawangaphandle kanye nokubambisana okuqotho, ukuze sakhe ikusasa elingcono.
