Izitini zokufaka izinto ezilula ezingasindi zokokhela ingilazi zingahlukaniswa zibe izigaba eziyisi-6 ngokuya ngezinto zazo zokusetshenziswa ezihlukene. Ezisetshenziswa kakhulu izitini ze-silica ezingasindi nezitini ze-diatomite. Izitini zokufaka ugesi ezilula zinezinzuzo zokusebenza okuhle kokufakwa kwe-thermal, kodwa ukumelana kwazo nokucindezela, ukumelana ne-slag, nokumelana nokushaqeka kokushisa kubi, ngakho azikwazi ukuxhumana ngqo nengilazi encibilikisiwe noma ilangabi.
1. Izitini ze-silica ezingasindi. Isitini esingasindi sokufakwa kwe-silica siwumkhiqizo we-insulation refractory owenziwe nge-silica njengento eluhlaza eyinhloko, enokuqukethwe kwe-SiO2 okungengaphansi kwama-91%. Ukuminyana kwezitini zokufakwa kwe-silica engasindi ngu-0.9~1.1g/cm3, futhi ukuqhutshwa kwaso okushisayo kuyingxenye kuphela yaleyo yezitini ezijwayelekile ze-silica. Inokumelana nokushaqeka okuhle kokushisa, futhi izinga lokushisa layo elithambile ngaphansi komthwalo lingafinyelela ku-1600 ℃, eliphakeme kakhulu kunalelo lezitini zobumba zobumba. Ngakho-ke, izinga lokushisa eliphezulu lokusebenza kwezitini zokufakelwa kwe-silica lingafinyelela ku-1550 ℃. Ayinciphi lapho amazinga okushisa aphezulu, futhi inokwanda kancane. Isitini esilula se-silica ngokuvamile sikhiqizwa nge-crystalline Quartzite njengempahla eluhlaza, futhi izinto ezivuthayo ezifana ne-coke, i-anthracite, sawdust, njll. zengezwa ezintweni ezingavuthiwe ukwenza isakhiwo esinezimbotshana kanye nendlela yokugwebulwa kwegesi ingasetshenziswa ukwenza isakhiwo esinezimbotshana.
2. Izitini ze-Diatomite: Uma ziqhathaniswa nezinye izitini zokufaka izinto ezingasindi, izitini ze-diatomite zine-conductivity ephansi yokushisa. Izinga lokushisa layo lokusebenza liyahlukahluka ngokuhlanzeka. Izinga lokushisa layo lokusebenza ngokuvamile lingaphansi kuka-1100 ℃ ngoba ukushwabana komkhiqizo kukhulu uma kuqhathaniswa namazinga okushisa aphezulu. Izinto zokusetshenziswa zesitini se-diatomite zidinga ukushiswa ekushiseni okuphezulu, futhi i-silicon dioxide ingaguqulwa ibe yi-quartz. I-lime ingabuye yengezwe njenge-binder kanye ne-mineralizer ukukhuthaza ukuguqulwa kwe-quartz ngesikhathi sokudubula, okuzuzisa ukuthuthukisa ukumelana nokushisa komkhiqizo nokunciphisa ukuncipha emazingeni okushisa aphezulu.
Ushicilelo olulandelayo sizoqhubeka nokwethula ukuhlukaniswa kweisitini esingasindi sokufakelwaokokushisela ingilazi. Sicela uhlale ubukele!
