Uthotho lwe-CCEFIRE® DEHA Izitena ezichasene ne-alumina ephezulu luhlobo lwezinto ezichasene ne-alumina ezinomxholo we-alumina ongaphezulu kwama-48%. Izitena ezichasene ne-alumina ephezulu zenziwa nge-calcination kunye nokubumba kwi-bauxite kunye nezinye izinto eziluhlaza ezinomxholo ophezulu we-alumina. Ngokwemixholo eyahlukeneyo ye-alumina kwizitena ze-alumina eziphezulu, ukumelana kwayo nomlilo, ukunganyamezeli phantsi komthwalo, amandla okucinezelwa kunye nezinye izalathisi ziyahluka.
Umgangatho weMveliso oZinzileyo
Ulawulo olungqongqo lwezinto ezikrwada
Lawula umxholo wokungcola, qinisekisa ukuncipha kobushushu obuphantsi, kwaye uphucule ukumelana nobushushu
1. Unesiseko esikhulu se-ore, izixhobo zobungcali zokumba, kunye nokukhetha okungqongqo kwezinto ezikrwada.
2. Izinto eziluhlaza ezingenayo ziyavavanywa kuqala, emva koko izinto eziluhlaza ezifanelekileyo zigcinwa kwindawo yokugcina izinto eziluhlaza ekhethiweyo ukuqinisekisa ubunyulu bazo.
3. Izinto ezisetyenziswa kwi-CCEFIRE Izitena ze-alumina eziphezulu zinomlinganiselo ophantsi wokungcola kunye ne-oxides engaphantsi kwe-1%, njengesinyithi kunye neentsimbi ze-alkali. Ke ngoko, izitena ze-alumina eziphezulu ze-CCEFIRE zinamandla aphezulu okuchasana nokungcola.
Ulawulo lwenkqubo yemveliso
Nciphisa umxholo weebhola ze-slag, qinisekisa ukuhanjiswa kobushushu obuphantsi, kwaye uphucule ukusebenza kobushushu
1. Inkqubo yokudibanisa izinto ngokuzenzekelayo iqinisekisa ngokupheleleyo uzinzo lokwakheka kwezinto ezikrwada kunye nokuchaneka okungcono kumlinganiselo wezinto ezikrwada.
2. Ngemizila yemveliso ezenzekelayo ephucukileyo kwihlabathi liphela yee-furnances zetonela ezinobushushu obuphezulu, ii-shuttle furnances, kunye nee-rotary furnances, iinkqubo zemveliso ukusuka kwizixhobo eziluhlaza ukuya kwiimveliso ezigqityiweyo zilawulwa yikhompyutha ngokuzenzekelayo, ukuqinisekisa umgangatho wemveliso ozinzileyo.
3. Iifeni ezizenzekelayo, ulawulo lobushushu oluzinzileyo, ukuhanjiswa kobushushu obuphantsi kwe-CCEFIRE Izitena ze-alumina eziphezulu, ukusebenza kakuhle kobushushu, utshintsho olusisigxina lomgca olungaphantsi kwe-0.5%, umgangatho ozinzileyo, kunye nobomi benkonzo obude.
4. Iintlobo ngeentlobo zezitena ze-alumina eziphakamileyo zingenziwa ngokweedizayini. Zinobukhulu obuchanekileyo obunempazamo ye +1mm kwaye zilungele abathengi ukuzifakela.
Ulawulo lwemeko
Qinisekisa uxinano olukhulu kwaye uphucule ukusebenza kobushushu
1. Ukuthunyelwa ngakunye kunomhloli womgangatho ozinikeleyo, kwaye ingxelo yovavanyo inikezelwa ngaphambi kokuba iimveliso ziphume kumzi-mveliso ukuqinisekisa umgangatho wokuthunyelwa ngakunye kwe-CCEFIRE.
2. Uhlolo lomntu wesithathu (olufana ne-SGS, i-BV, njl.njl.) luyamkelwa.
3. Imveliso ihambelana ngokungqongqo nesiqinisekiso senkqubo yolawulo lomgangatho we-ASTM.
4. Iphakheji yangaphandle yekhathoni nganye yenziwe ngeengqimba ezintlanu zephepha lekraft, kunye nephakheji yangaphandle + ipallet,, efanelekileyo ekuthuthweni okude.
Iimpawu Ezibalaseleyo
1. Ukungaguquguquki kwe-refractoribility
Ukungaguquguquki kwezitena ze-alumina eziphezulu ze-CCEFIRE kuphezulu kunoko kwezitena zodongwe eziguquguqukileyo kunye nezitena ze-semi-silica, kufikelela kwi-1750~1790℃, oluluhlobo lwezixhobo zokuguquguquka ezikumgangatho ophezulu.
2. Ubushushu bokuthambisa umthwalo
Ekubeni iimveliso ze-alumina eziphezulu zine-Al2O3 ephezulu, ukungcola okuncinci, kunye neglasi engatshiyo kakhulu, ubushushu bokuthambisa umthwalo buphezulu kunobo bezitena zodongwe, kodwa ngenxa yokuba iikristale ze-mullite azenzi isakhiwo senethiwekhi, ubushushu bokuthambisa umthwalo abukabi phezulu njengezitena ze-silica.
3. Ukumelana ne-slag
Izitena ze-CCEFIRE ezine-alumina ephezulu ziqulathe i-Al2O3 engaphezulu, kufutshane nezinto ezingathathi cala ezichasayo, ukuze zikwazi ukumelana nokukhukuliseka kwe-asidi slag kunye ne-alkaline slag. Ngenxa yomxholo we-SiO2, ukumelana ne-alkaline slag kubuthathaka kune-asidi slag.
Izitena ze-alumina eziphezulu ezibonakala ngokuqina okuphezulu kobushushu, ukunganyamezeli okuphezulu ngaphezu kwe-1770 degrees, ukumelana okuhle kwe-slag, ezisetyenziselwa ikakhulu i-furnace top yombane, i-shaft furnace, i-hot blast furnace, i-ladle, i-melt iron, i-samente furnace, i-glass furnace kunye nezinye izinto ezishushu. Zisetyenziswa kakhulu ekwenzeni isinyithi, ekwenzeni intsimbi, kushishino lweekhemikhali, kwisamente nakwamanye amashishini.
