Wadanne iri ne silica alumina refractory tubalin sun hada?

(1) tubalin Silica: koma zuwa tubalin da ke ɗauke da fiye da 293% SiO, kuma sune manyan nau’ikan tubalin acid. Ana amfani da shi musamman don gina tanda na coke, kuma ana amfani da shi don rumbun adana kaya da sauran sassa masu ɗaukar zafi na kiln ɗin zafi don gilashin daban-daban, yumbu, na’urorin carbon, da bulo mai hana ruwa. Hakanan ana amfani dashi a cikin sassa masu ɗaukar zafi mai zafi na murhun fashewar zafi, amma ba’a amfani da shi a cikin kayan zafi da ke ƙasa da 600 ° C kuma tare da manyan canjin yanayin zafi.

(2) Tulin yumbu: Tulin laka galibi sun haɗa da mullite (25% -50%), lokacin gilashi (25% -60%), cristobalite da quartz (har zuwa 30%). Yawancin lokaci ana amfani da yumbu mai wuya a matsayin albarkatun kasa, kayan da balagagge an riga an ƙaddara su, sa’an nan kuma haɗe shi da yumbu mai laushi, wanda aka kafa ta hanyar bushewa ko filastik, kuma zafin jiki shine 1300 ~ 1400 C don ƙone kayan bulo na yumbu. Hakanan zaka iya ƙara ƙaramin gilashin ruwa, siminti da sauran masu ɗaure don yin samfuran da ba a ƙone ba da kayan amorphous. Bulo ne mai jujjuyawar da aka saba amfani da shi a cikin tanderun fashewa, murhu mai zafi, tanda mai dumama, tukunyar wuta, kiln na lemun tsami, kilns na jujjuya, tukwane da kilns na harbin bulo.

(3) High alumina refractory tubali: The ma’adinai abun da ke ciki na high alumina refractory tubali ne corundum, mullite da gilashi lokaci. Abubuwan da ke cikin sa ya dogara da rabon AL2O3/SiO2 da nau’i da adadin ƙazanta. Ana iya rarraba tubalin da ke jujjuyawa bisa ga abun ciki na AL2O3. Kayan albarkatun kasa sune manyan alumina bauxite da sillimanite na halitta, da kuma waɗanda aka haɗe da corundum fused, sintered alumina, mullite roba, da clinker calcined tare da alumina da yumbu a cikin nau’i daban-daban. Mafi yawa ana samar da shi ta hanyar sintering. Amma samfuran kuma sun haɗa da tubalin simintin gyare-gyare, bulogin hatsi, bulogin da ba a kone ba da kuma bulogin da ba su da siffa. High alumina refractory tubalin ana amfani da ko’ina a cikin karfe masana’antu, wadanda ba na karfe masana’antu da sauran masana’antu.

(4)Bulo mai jujjuyawa na corundum: tubalin corundum yana nufin wani nau’in bulo mai jujjuyawa tare da abun ciki na AL2O3 wanda bai gaza 90% ba kuma babban matakin corundum. Ana iya raba shi zuwa tubalin corundum da aka yi da shi da tubalin corundum da aka haɗa.
