Idizayini Evuselelekayo Ye-Pink Fused Alumina/Pink Aluminium Oxide/Intengo yePFA

Mayelana nobubanzi bentengo obunamandla, sikholwa ukuthi uzosesha kude nakude nanoma yini engasehlula.Singasho kalula nje ngokuqiniseka okuphelele ukuthi ngezinga eliphezulu kangaka kumazinga entengo anjalo siphansi kakhulu ngokuzungezile Ngedizayini Evuselelekayo Ye-Pink Fused Alumina/Pink Aluminium Oxide/Intengo yePFA, Empeleni kuwudumo lwethu olukhulu ukwanelisa izidingo zakho. ngithemba ngobuqotho ukuthi singabambisana kalula nawe ngaphakathi kokukhona okuzungezile.
Mayelana nobubanzi bentengo obunamandla, sikholwa ukuthi uzosesha kude nakude nanoma yini engasehlula.Singasho kalula ngokuqiniseka okuphelele ukuthi ngekhwalithi ephezulu kangako kumazinga entengo anjalo siphansi kakhulu kuwo.I-China Pink Fused Alumina neChromic Corundum, Ekhulwini elisha leminyaka, sithuthukisa umoya wethu webhizinisi “wokubumbana, ukukhuthala, ukusebenza kahle okuphezulu, ukusungula izinto ezintsha”, futhi sinamathele kunqubomgomo yethu”ngokusekelwe kwikhwalithi, yiba ngumuntu osomabhizinisi, olwela uhlobo lokuqala”.Besingathatha leli thuba elihle ukudala ikusasa eliqhakazile.

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.

Mayelana nobubanzi bentengo obunamandla, sikholwa ukuthi uzosesha kude nakude nanoma yini engasehlula.Singasho kalula nje ngokuqiniseka okuphelele ukuthi ngezinga eliphezulu kangaka kumazinga entengo anjalo siphansi kakhulu ngokuzungezile Ngedizayini Evuselelekayo Ye-Pink Fused Alumina/Pink Aluminium Oxide/Intengo yePFA, Empeleni kuwudumo lwethu olukhulu ukwanelisa izidingo zakho. ngithemba ngobuqotho ukuthi singabambisana kalula nawe ngaphakathi kokukhona okuzungezile.
