Ingcaciso yeMveliso

Izinto ezisetyenziswa ekrwada kwiimveliso ze-chromium corundum sisisombululo esiqinileyo esenziwe ngokunyibilika kobushushu obuphezulu be-alumina kunye ne-chromium oxide kumlinganiselo othile.Eyona mathiriyeli ekrwada yi-bauxite ephezulu (okanye i-alumina yamashishini) ngokongeza isixa esifanelekileyo sechromite kunye nokunciphisa.I-ejenti inyibilika kwiqondo lokushisa eliphezulu kwiziko lombane, kwaye i-chromium etyhidiweyo igalelwe kwi-mold ukuze ipholiswe kancinane, kwaye emva koko yenziwe emva kokuba i-annealing..

Imveliso ye-Chromium corundum refractory edityanisiweyo ye-chrnmecorundum refrac-tory ikwabizwa ngokuba yi-fused cast chrnmecorundum refrac-tory.Imveliso ye-refractory edibeneyo eyenziwe ngesisombululo esiqinileyo se-alumina kunye ne-chromium oxide kunye nenani elincinci le-spinel, eliqulethe i-60% ukuya kwi-87% ye-alumina kunye ne-30% ye-chromium oxide.Ubuninzi be-bulk density yi-3.2-3.9g / cm3;, amandla okushisa aphezulu aphezulu, xa kuthelekiswa nezinye iintlobo ze-corundum refractories, ukuxhatshazwa kwe-corrosion ye-glass melt iyona inamandla.Ingasetyenziswa njengolwaleko lweziko oludibana ngokuthe ngqo neglasi etyhidiweyo.

I-Chromium corundum refractories isetyenziswa ngokubanzi kumbane we-slurry pressurized gasifier, i-ladle yokucoca iziko kunye ne-carbon black reactor lining, i-petrochemical industry slag i-gasification i-furnace lining kunye neglasi yokunyibilika kwesithando somlilo, njl. njl., kwaye ingasetyenziselwa ukufudumeza I-chrome Isitena seqonga lecorundum yesithando somlilo sisixhobo esiyimfuneko kwishishini lobushushu obuphezulu.

I-AL203 kunye ne-Cr2O3 yesakhiwo se-corundum, i-radius ye-Cr3 + yi-0.620, kunye ne-radius ye-AL3 + yi-0.535.Ngokwefomula yobungqina:

Ekubeni umahluko phakathi kwe-Cr3+ kunye ne-AL3+ ion radii ingaphantsi kwe-15%, i-Cr ions ingakwazi ngokuqhubekayo kwaye ingenasiphelo i-AL kwi-lattice ye-AL203, yenze isisombululo esingenasiphelo esingenasiphelo esisisigxina.

Ubume bekristale be-Cr203 kunye ne-AL203 ziyafana, kwaye i-radius ye-ionic ihluke nge-13.7%.Ke ngoko, i-Cr203 kunye ne-AL203 zinokwenza isisombululo esiqinileyo esingenasiphelo kwiqondo lobushushu eliphezulu.Ukusuka kwimbono yomgca wesigaba solwelo-oluqilima, ngokunyuka komxholo we-Cr203, iqondo lobushushu apho inqanaba lolwelo liqala ukubonakala nalo liyenyuka.Ke ngoko, ukongeza inani elifanelekileyo le-Cr203 ukuya kwi-AL203 kunokuphucula kakhulu iipropathi zoomatshini kunye nokusebenza kwenkonzo yobushushu obuphezulu be-corundum refractories.

I-Cr203 inokwenza indawo ephezulu yokunyibilika okanye i-eutectic enobushushu obuphezulu bokunyibilika kunye neeoksidi ezininzi eziqhelekileyo.Umzekelo, i-FeO·Cr203 spinel eveliswe yi-Cr203 kunye ne-Feo inendawo yokunyibilika ukuya kwi-2100℃;I-Cr203 kunye ne-AL203 inokwenza isisombululo esiqinileyo esiqhubekayo.Ukongeza, i-Cr203 inokunyusa kakhulu i-viscosity ye-slag kunye nokunciphisa ukumanzi kwe-slag, ngaloo ndlela inciphisa ukubola kwe-slag kwi-refractory.Ke ngoko, ukongeza isixa esifanelekileyo se-Cr203 kwimathiriyeli echasayo kunokunciphisa kakhulu ukuchitheka kwesakhiwo semathiriyeli yelinen yesithando somlilo esibangelwa kukukhukuliseka kwe-slag.Akukho nto ibonakalayo phakathi kwesakhono sokubola kwe-slag kwi-chromium corundum refractories kunye nesiseko se-slag.

Isitena se-chromium corundum esenziwe nge-chromium corundum refractory material sisesithandweni somlilo.Xa isiseko se-slag si-2, isitena se-chromium corundum sinokumelana ne-iron slag corrosion;xa isiseko se-slag si-0.2, ubunzulu be-corrosion ye-slag yethusi ukuya kwisitena se-chromium corundum Esona sincinci;xa isiseko se-slag siyi-0.35, ubunzulu be-tin slag kwisitena se-chrome corundum buncinci;xa i-lead slag basicity yi-0.3, ubukhulu bentsalela bukhulu kunye nobunzulu be-reaction layer, i-rosion layer kunye ne-penetration layer incinci.Xa i-alkalinity ye-slag i-0.37, ukuxhathisa kwe-corrosion yezitena ze-chrome corundum iyona nto ingcono.

Siqinisekile ukuba ngamaphulo adibeneyo, ishishini loshishino phakathi kwethu liya kusizisela inzuzo efanayo.Singakuqinisekisa ngokulula ukuba uthengisa umgangatho olungileyo kunye nethegi yexabiso elinobundlavini lika-2019 uMgangatho oLungileyo wePinki/Ruby Fused Aluminium Oxide, Samkela ithemba lokwenza ishishini kunye nawe kwaye sinethemba lokonwaba ekuncamatheleni ulwazi olongezelelekileyo lwezinto zethu.
2019 Umgangatho olungileyoChina Pink Fused Alumina kunye Chromic Corundum, Umgangatho ogqwesileyo uvela ekubambeleleni kwethu kuzo zonke iinkcukacha, kwaye ukwaneliseka kwabathengi kuvela ekuzinikezeleni kwethu ngokunyanisekileyo.Ngokuthembela kubuchwepheshe obuphambili kunye nodumo kwishishini lentsebenziswano elungileyo, sizama konke okusemandleni ethu ukuhambisa izinto ezisemgangathweni kunye neenkonzo kubathengi bethu, kwaye sonke sizimisele ukomeleza utshintshiselwano kunye nabathengi basekhaya nabangaphandle kunye nentsebenziswano enyanisekileyo, ukwakha ikamva elingcono.
