Ukusebenza kwemveliso:Inozinzo oluluqilima lobushushu obuphezulu, ukuxhathisa ukothuka kwe-thermal, ukuxhathisa ukunxiba, ukuxhathisa ukubola kweekhemikhali kunye nezinye iimpawu.
Eyona nto isetyenziswayo:Ikakhulu isetyenziswa kwiindawo ezitshintshayo zeekhilni zesamente ezijikelezayo, iziko lokubola, imibhobho yomoya ephakamileyo, kunye nezinye izixhobo ezishushu ezifuna ukuxhathisa ukothuka kwe-thermal.
Iimpawu zeMveliso:Njengezinto ezisisiseko zoshishino lwe-refractory, izitena eziphezulu ze-alumina zineempawu zokuchasana okuphezulu, ubushushu obuphezulu bomthwalo-othambileyo (malunga ne-1500 ° C), kunye nokumelana nokukhukuliseka okulungileyo.Zisetyenziswa ngokubanzi kwiikhilni zoshishino kumashishini ahlukeneyo.Nangona kunjalo, ngenxa yomxholo wesigaba esiphezulu se-corundum yezitena eziphakamileyo ze-alumina eziqhelekileyo, i-crystals yesigaba se-corundum kwiimveliso ze-sintered zikhulu, kwaye ukuqhekeka kunye nokuhluthwa kukulungele ukwenzeka xa kuhlangabezana nokupholisa ngokukhawuleza kunye neemeko zokufudumeza.Ukuzinza kokutshatyalaliswa kwe-thermal phantsi kwe-1100 ° C iimeko zokupholisa amanzi kuphela Inokufikelela kumaxesha angama-2-4.Kwinkqubo yemveliso yesamente, ngenxa yokunciphisa ubushushu bokushisa kunye neemfuneko zokusebenza kwezinto eziphikisayo ukunamathela kwisikhumba se-alumina, izitena eziphezulu ze-alumina zinokusetyenziswa kuphela kwindawo yokutshintsha kwe-rotary, umsila we-kiln kunye ne-preheater yesithando somlilo. .
Izitena eziphezulu ze-alumina ezichasene ne-alumina zizitena eziphezulu ze-aluminium ezinezakhiwo ezichasene ne-flaking eziveliswe ngokusekelwe kwi-clinker ephezulu ye-aluminium kwaye zongezwa nge-ZrO2 okanye ezinye izinto.Zinokwahlulwa zibe ngamacandelo amabini, enye i-anti-flaking high-alumina izitena eziqulethe i-ZrO2, kwaye enye i-Uhlobo lokuqala luyi-anti-flaking high alumina isitena esingenayo i-ZrO2.
Izitena ezichasene ne-alumina ezichasene ne-alumina ziyakwazi ukuxhathisa imithwalo yobushushu obuphezulu, musa ukucutha umthamo kwaye ube nokwandiswa okufanayo, musa ukukhahlela okanye ukudilika, amandla obushushu obuqhelekileyo obuphezulu kunye namandla aphezulu obushushu obuphezulu, ubushushu obuphezulu bokuthambisa umthwalo, kunye ube nokumelana nobushushu.Iyakwazi ukumelana neempembelelo zokutshintsha kweqondo lokushisa ngokukhawuleza okanye ukufudumeza okungalinganiyo, kwaye ayiyi kuqhekeza okanye ikhuphe.Umahluko phakathi kwe-anti-flaking izitena eziphezulu ze-alumina eziqukethe i-ZrO2 kunye ne-anti-flaking izitena eziphezulu ze-alumina ngaphandle kwe-ZrO2 zilele kwiindlela zabo ezahlukeneyo zokulwa nokuvutha.I-ZrO2 ene-anti-flaking izitena eziphezulu ze-alumina zisebenzisa izinto ze-zircon ukuze zenze ukusetyenziswa kwe-corrosion resistance.I-ZrO2 ixhathisa ukukhukuliseka kwesulfure-chlor-alkali.Ngexesha elifanayo, kumaqondo okushisa aphezulu, i-SiO2 equlethwe kwi-zircon iya kutshintshwa kwisigaba se-crystal ukusuka kwi-cristobalite ukuya kwisigaba se-quartz, okubangelwa umphumo othile wokwandisa umthamo, ngaloo ndlela unciphisa umngcipheko wokuthintela isulfure-chlor-alkali.Kwangaxeshanye, kuthintela spalling ngexesha leenkqubo ezishushu nezibandayo;anti-flaking izitena eziphezulu ze-alumina ezingenayo i-ZrO2 ziveliswa ngokudibanisa i-andalusite kwizitena eziphezulu ze-alumina.I-andalusite kwimveliso isetyenziselwa i-mulliteization yesibini kwi-sement kiln.Ivelisa umphumo ongenakuguqulwa we-micro-expansion ukwenzela ukuba imveliso ayiyi kuncipha xa ipholile, ukucima uxinzelelo lwe-shrinkage kunye nokuthintela ukuchithwa kwesakhiwo.
Xa kuthelekiswa ne-anti-spalling high-alumina izitena ezingenayo i-ZrO2, i-anti-spalling high-alumina izitena eziqukethe i-ZrO2 zinokumelana okungcono nokungena kunye nokukhukuliseka kwe-sulfure, i-chlorine kunye ne-alkali, ngoko baneempawu ezingcono zokulwa ne-flaking.Nangona kunjalo, ngenxa yokuba i-ZrO2 yinto enqabileyo, iyabiza , ngoko ke ixabiso kunye nexabiso liphezulu.I-Anti-flaking izitena eziphezulu ze-alumina eziqukethe i-ZrO2 zisetyenziselwa kuphela ummandla wenguqu yee-sement rotary kilns.I-Anti-flaking high-alumina izitena ezingenayo i-ZrO2 zisetyenziswa kakhulu kwii-furnaces zokubola zemigca yokuvelisa i-samente.
