China haske nauyi high alumina thermal rufi bulo factory da kuma masana'antun | Rongsheng

High alumina rufi tubali ne wani nau'i na refractory, babban bangaren wanda shi ne Al2O3. Idan abun ciki na Al2O3 ya fi 90%, ana kiran shi tubalin corundum. Saboda albarkatu daban-daban, ma'auni na ƙasashe daban-daban ba su da cikakkiyar daidaituwa. Alal misali, a cikin ƙasashen Turai, ƙananan iyaka na abun ciki na Al2O3 don manyan alumina refractories shine 42%. A cikin kasar Sin, abun ciki na Al2O3 a cikin bulo mai tsayi na alumina gabaɗaya ya kasu kashi uku: Matsayi na I - Al2O3 abun ciki> 75%; aji II - Al2O3 abun ciki shine 60-75%; aji III - Al2O3 abun ciki shine 48-60%.
