Ukwahlula njani phakathi komgangatho olungileyo kunye nomgangatho ombi xa uthenga izitena eziphezulu zealumum?

Ukwahlula njani umgangatho wezitena eziphezulu zealumini xa uthenga izitena eziphezulu zealumumina? Kwelinye icala, inokujongwa ngeliso lenyama, kwelinye icala, inokufunyanwa kwaye yahluke.

Amanqaku amabini aphambili abonwa ngamehlo ahamba ze:

A. Ukubonakala kokungcola

Ukujonga umxholo wokungcola kumphezulu wezitena ezitsalayo, sihlala sibona amabala amnyama phezu kwezitena eziphezulu zealumumina. Oku kukungcola kwimathiriyeli ekrwada. Ngokwethiyori, ukungcola okumbalwa kubangcono, kuba obu bumdaka ikakhulu zii-oxides zentsimbi. , Iyancitshiswa nje ukuba ibe yintsimbi etyhidiweyo ephuma kwindawo enobushushu obuphezulu besithando somlilo, isenza umonakalo kwisakhiwo sezitena esichasayo, emva koko ichaphazele ubomi benkonzo yesitena esikhanyelayo. Njengemveliso yoshishino, umgangatho wezitena ezichasayo uchaphazela ngokuthe ngqo iindleko zokuvelisa kunye nezemveliso zeshishini. Izitena eziphikisayo ezingaphantsi azizukubangela kuphela iindlela ezahlukeneyo zokulungisa kwimveliso, zonyuse iindleko zokuvelisa, kodwa zikonyuse nolwakhiwo kunye nemveliso. Iingozi ezifihlakeleyo ezingathethekiyo.

B. Umbala wembonakalo kunye ne-lubricity yomphezulu

Ukubona isitena sokuphikisa, kufuneka sibone imbonakalo yombala kunye nokuthamba kwezitena. Umgangatho wezitena ezitshixayo awulunganga kakhulu, kwaye umphezulu wokuthambisa uthambe kakhulu, nto leyo ekhokelela kukomelela kwezitena ezikhanyelayo. Ukufana kwembonakalo kunye nombala wezitena ezibonakalisayo zibonisa ukuba ngaba izinto zixutywe ngokulinganayo ngexesha lokuveliswa kwezitena ezibonakalisayo. Ukuhanjiswa okungalinganiyo kwezinto kuya kukhokelela ekusasazeni ngokungalinganiyo kwezitena ezitsalayo, kwaye ke kunciphise amandla kunye nobomi benkonzo yezitena ezitsalwayo.

Amanqaku amathathu aphambili ahlukaniswe kukufumanisa:

A. ukuxhathisa ngamakhoboka

Isitena se-alumina esiphakamileyo sine-Al2O3 engaphezulu, eyinto engathathi hlangothi kwaye inokusetyenziswa kwindawo enealkali okanye asidi. Ngenxa yokuba iqulethe i-silica silicon SIO2, ukuxhathisa kwe-slag kwindawo ye-alkaline kungcono kunaleyo ye-asidi.

B. Layisha ubushushu obuthambileyo

Ngenxa yokuba iimveliso zealumina eziphezulu zineAl2O3 ephezulu, ukungcola okuncinci, kunye neglasi encinci enefusus, ubushushu obuthambisa umthwalo buphezulu kunobo bezitena zodongwe, kodwa ngenxa yokuba amakristali e-mullite engenzi ubume benethiwekhi, iqondo lobushushu lokusetyenziswa alilunganga njengelo Ukuchasana okunesiliceous. .

C. Ukuchacha kwakhona

Ukuphindaphindwa kwezitena eziphezulu zealumum kuphezulu kunezitena zodongwe, kufikelela kwi-1750 degrees celcius ukuya kwi-1790 degrees celcius, nto leyo ikumgangatho ophezulu wokuphamba.

Le ingasentla yindlela yokwahlula umgangatho wezitena eziphezulu zealuminiy, ndiyathemba ukuba iya kuba luncedo kuwe.
