Liyini iphuzu lokuncibilika izitini ezikhanyisayo?

Izitini eziphikisayo ziyizinto ezikwazi ukumelana nokushisa, ezisetshenziswa kakhulu ekusebenzeni okunokushisa okuphezulu okufana noshimula namakhilni. Kodwa-ke, izitini eziphikisayo nazo zinamaphuzu okuncibilika. Izinhlobo ezibonakalayo zezitini eziphikisayo zihlukile. Khetha uhlobo lwezitini eziphikisayo ngokusho komsebenzi wakho siqu.

I-refractory eyenziwe ngobumba obungashi noma ezinye izinto eziphikisayo. Ikakhulukazi esetshenziselwa ukwakha isithando somlilo esincibilikisayo, ingamelana nezinga lokushisa eliphakeme elingu-1,580℃-1,770℃;

izitini zobumba ziyizinto eziphikisayo ezine-asidi ezibuthakathaka. Uma ukuphikiswa kwezitini zobumba ezisetshenziswa ezithandweni zezimboni kungaphezu kuka-1600 ° C, izinga lokushisa lokuqala lokuthambisa umthwalo liyi-1250-1300 ° C kuphela. Izitini zobumba ezisetshenziswa izithando zezimboni ze-Yiran zicebile kakhulu ezintweni ezingavuthiwe, ubuchwepheshe bokukhiqiza abulula, futhi izindleko ziphansi. Asetshenziswa kakhulu ekwakhiweni kwezindawo zokushisa ezihlukene ze-Yiran kanye namapayipi, oshimula, kanye noshimula bezindawo zokushisa ukushisa zase-Yiran. Umzimba wesithando somlilo, imishini yokushisa imfucuza kanye nezishisi zesistimu yokuvutha, njll.

Isitini seMagnesia siyinto ephikisayo enokuqukethwe kwe-MgO ngaphezu kuka-80-85% kanye ne-periclase njengediphozithi yamaminerali eyinhloko. Iphuzu lokuncibilika le-MgO liphezulu njenge-2800 ℃. I-refractoriness yesitini se-magnesia ingaphezu kuka-2000 ℃, kodwa indawo yayo yokuthambisa ngaphansi komthwalo iphansi kakhulu, inqobo nje uma i-1500-1550 ℃. Lokhu kungenxa yokuthi amakristalu e-periclase azungezile ahlanganiswe ne-forsterite encibilikayo ephansi (CaO·MgO·SiO2) kanye nengilazi, kuyilapho i-periclase ingenzi inethiwekhi ye-crystalline eqhubekayo, izinga lokushisa lokushintsha komthwalo liphansi kakhulu, futhi isiqalo Ububanzi bokushisa kusukela ekunciphiseni. kuya ku-40% deformation incane kakhulu, inqobo nje uma 30-50 ℃. Ukuzinza okushisayo kwezitini ze-magnesia nakho kumpofu, futhi kumane kuqhekeke ngesikhathi sokupholisa okusheshayo nokushisa, okuyisici esibalulekile emonakalweni wezitini ze-magnesia.

Izitini ezijwayelekile ze-corundum zifanele ukuvala indawo yomlilo yeziko elisindayo likawoyela wegesi enomfutho osebenzayo we-3MPa noma ngaphansi, ingxenye ebalulekile yolwelwesi lwama-incinerators anosawoti wamanzi angcolile, nezitini ezikhazimulayo zokushisa ezisebenza emazingeni okushisa aphezulu. Ngokuvamile, izinga lokushisa lokusetshenziswa kwezitini ze-corundum lingaphansi kwe-1600-1670 degrees Celsius. Izitini zobumba ezilula ezingasindi zisetshenziswa njengezindwangu zomlilo ezingadliwe yi-slag ephezulu yokushisa kanye namagesi abolayo. Ngokuya ngomthamo, izinga lokushisa lokusebenza liphakathi kuka-1150-1400 degrees Celsius

Okungenhla isifinyezo samaphuzu ahlukene okuncibilika ezitini eziphikisayo ngokwezinhlobo ezahlukene. Uma ukhetha izitini eziphikisayo, ungaphinda ukhethe okulungile ngokusho kwendawo yokuncibilika.
