Isitini sokukhonona esigobile
Isitini sokukhonona esigobile
Ikhwalithi ephezulu nentengo enhle kakhulu, insiza enhle
Izinzuzo zomkhiqizo: ukumelana okuhle kokushisa okushisayo, ukumelana nokuqina okuqinile, amandla aphezulu wokucindezela.
incazelo yomkhiqizo
Izitini ezakhiwe njenge-arc zibizwa nangokuthi izitini ze-arc. Izitini ze-high-alumina arc ziwuhlobo lwezitini ezimise okhethekile. I-arc yesitina se-arc iyisiyingi esiyindilinga kanti omunye umkhawulo uyindawo emgodini. , Ingabuye yakhiwe ibe yindilinga, lolu hlobo lwezitini luyasetshenziswa kuladle. Isitini se-arc sisetshenziswa kakhulu njengendwangu yangaphakathi yebhakede lensimbi. Kwakuvamise ukuba ikakhulu ubumba. Manje kancane kancane ithathelwa indawo yizitini eziphakeme ze-alumina. Izitini eziphakeme ze-alumina zibonakaliswa ukumelana okuhle kokushisa okushisayo, ukumelana okuqinile kokugqwala namandla aphezulu wokucindezela.
Izitini eziphikisayo ze-high-aluminium arc ziqukethe i-aluminium silicate ene-Al2O3 ngenhla kwama-48% kuye kuma-75%. Ukuphakama kokuqukethwe kwe-aluminium, ngcono ikhwalithi yezitini ze-high-aluminium arc. It is a material weakly acidic refractory, which is made of natural or artificial high-alumina materials (sillimanite, diaspore, high alumina, njll). Uma kuqhathaniswa nezitini zobumba, ukuphindaphinda kwalo (1750 ~ 1790 ℃) nokushisa kokuthambisa (1420 ~ 1500 ℃) kuphakeme, futhi ukumelana kwe-slag namandla alo okucindezela nakho kuphakeme.
