Ibhola elikhanyayo (ibhola yokugcina ubushushu)
Ibhola elikhanyayo (ibhola yokugcina ubushushu)
1. Ibhola ephezulu yealumine ineempawu zokuxhathisa okunamandla kwe-oxidation kunye nokumelana ne-slag. Ibhola ye-ceramic refractory inokutshintshwa ngokulula kwaye icocwe, kwaye iphinde isetyenziswe.
2. Iinkcukacha eziphambili zebhola ekhanyelayo: Φ40mm Φ50mm Φ60mm Φ70mm
3. Izinto zeemveliso zebhola ye-refractory zahlulwe: i-aluminium ephezulu, i-corundum, kunye ne-zirconium corundum.
4. Zininzi iindidi zeebhola ezinokuphinda zisetyenziswe, ezinokusetyenziswa kwiziko lokuguqula ubushushu obuphezulu kunye nobuphantsi, abaguquli, isiguquli se-hydrogenation, iitanki zedulfurization, kunye neebhola ezichasayo kunye nezixhobo zokuguqula ukufudumeza ezithathelwa indawo ziindawo ezishushu zentsimbi kunye nentsimbi. .
5. Ubushushu bokugcina i-porcelain iibhola ezikhuphayo zinezibonelelo zamandla aphezulu kwaye zinxibe ukumelana; ukuqhuba okukhulu kwe-thermal kunye nobushushu, ukugcina ubushushu obuphezulu ngokufanelekileyo; Iibhola ze-porcelain zokugcina ubushushu zinokuzinza okuhle kwe-thermal kwaye akukho lula ukukophula xa iqondo lobushushu litshintsha ngesiquphe. Ibhola yokugcina ubushushu ilungele ngokukodwa ukugcinwa kobushushu bokugcina ubushushu bezixhobo zokwahlula umoya kunye nokudubula kwesithando somlilo kwisityalo sentsimbi. Ibhola yokugcina ubushushu iphinda-phinda ubushushu begesi kunye nomoya, kwaye ibhola yokugcina i-ceramic yokugcina ubushushu yenza ukuba iqondo lobushushu lokutsha lifikelele ngokukhawuleza kwisinyithi esiqengqelekayo ukufudumeza i-billet. Iimfuneko.
6. Iibhola eziphakamileyo ze-alumina ze-ceramic refractory, umxholo ophezulu we-alumina, uxinano oluphezulu, amandla oomatshini aphezulu, ukumelana nokunxiba okuhle, iipropathi ezinzileyo zeekhemikhali, ukumelana nobushushu obugqwesileyo, iibhola ze-alumina eziphezulu ze-ceramic zisetyenziswa kakhulu, kwaye zinokusetyenziswa njengezigcwalisi zemichiza. Iibhola ze-ceramic eziphezulu zingasetyenziselwa ukugaya imidiya. I-alumina High yodongwe Iibhola ezikhutshelwayo zisetyenziswa kakhulu kwimichiza, ngoomatshini, ngombane, ukhuselo lokusingqongileyo kunye nezinye iinkalo.
1. Ibhola ephezulu yealuminium ekhanyisela umxholo weAl2O3. Inqaku elithandwayo ngumxholo we-aluminium oxide kwimathiriyeli eluhlaza yebhola ekhatywayo. Umxholo wealuminium umisela inqanaba lezinye iipropathi. Ke ngoko, sisalathiso esiphambili sokusebenza kwebhola eliyinjubaqa. Iibhola ezibonisa ukuphakama kwealuminium zingahlulwa zibe zindidi ezine ngokomxholo wealuminium: inqanaba lokuqala lomxholo wealuminium 75; Inqanaba lesibini iibhola eziphezulu zealuminium, ZN-65 kunye nomxholo wealuminiyam ongama-65%; Iibhola zenqanaba lesithathu eziphezulu zealuminium, ezinomxholo wealuminiyam 55% iZN-55.
2. Ubuninzi bobunzima ngumlinganiso wobunzima obomileyo bebhola ekhatywayo ukuya kwivolumu yayo iyonke, kwaye iyunithi yi-g / cm3. Ukuxinana kwesambuku ikakhulu kubonisa ukungqinelana kwebhola eliyinjubaqa. Ngokubanzi, ubuninzi beebhola ezichasayo zinxulumene kakhulu ne-porosity kunye nokwakhiwa kwezimbiwa. Kwibhola ye-refractory, kokukhona ubuninzi bexinene, kokungcono umgangatho wemveliso. Uxinano lwevolumu yeentlobo ezine zeebhola ezichasayo zezi: ibakala lokuqala lebhola ephezulu yealuminium ≥ 2.5; kwibakala lesibini ibhola alumina eliphezulu ≥ 2.3; kwibakala lesithathu ibhola alumina eliphezulu ≥ 2.1.
3. I-porosity ebonakalayo ngumyinge wevolthi evulekileyo yebhola ye-refractory kwivolumu iyonke. Ngokubanzi, i-slag kunye neegesi eziyingozi eziko zilungisa ibhola ekhanyayo ngokwayo nge pores ezivulekileyo. Ke ngoko, kuyafuneka ukuba ukubonakala okubonakalayo kwebhola eliyinjubaqa kuncinci ngangokunokwenzeka. I-porosity ebonakalayo yeendidi ezine zeebhola ezichasayo zezi: kwinqanaba lokuqala iibhola zealuminium≤24%; Inqanaba lesibini iibhola eziphezulu zealuminium≤26%; Inqanaba lesithathu iibhola eziphezulu zealumni≤28%.
4. Ixabiso lokumelana noxinzelelo kubushushu begumbi linempembelelo enkulu kwimveliso, ukuthuthwa kunye nokusebenza kokusebenza kwebhola eliyinjubaqa, ke ixabiso lokumelana noxinzelelo oluphezulu liyafuneka. Iyunithi ibonakalisiwe kwiKN. Amaxabiso oxhathiso oxinzelelo lweendidi ezine zeebhola ezikhutshelayo kubushushu begumbi zezi: ibhola ekhethekileyo yealuminium ≥ 25; kwibakala lokuqala ibhola ephezulu yealuminium ≥ 15; grade yesibini ibhola aluminium eliphezulu ≥ 10; grade lesithathu ibhola aluminium eliphezulu ≥ 8.
5. Ubushushu obuthomalisayo bebhola ekhatywayo bubhekisa kwiqondo lobushushu elikhubazeka kulo ngexesha lokusetyenziswa. Ubushushu obuthomalisayo kwiindidi ezine zeebhola ezichasayo zezi: iibhola ezikumgangatho ophezulu wealuminium ≥1530 ℃; Iibhola zokuqala ze-aluminium ephezulu -1480 ℃; Iibhola ezikumgangatho wesibini ezikumgangatho ophezulu wealuminium ≥1450 ℃; kunye neebakala zebhola ephezulu ye-aluminium ≥1400 ℃.
6. Uzinzo lokothuka obushushu kukukwazi kwebhola eliyinjubaqa ukumelana notshintsho lobushushu kubushushu obukhawulezayo nobushushu ngokukhawuleza. Ukulinganisa isalathiso sokusebenza kwebhola enqabileyo, ihlala ichazwa ngenani lamaxesha phantsi kwemeko yokupholisa amanzi ayi-1100.. Uzinzo lomothuko weentlobo ezine zeebhola ezichasayo zezi: ibhola ekhethekileyo yealumnium amaxesha ali-10; grade lokuqala ibhola alumina eliphezulu, grade grade alumina eliphezulu eliphezulu, kunye nebakala lesithathu ibhola alumina eliphezulu times amaxesha 15.
