Ingcaciso yeMveliso

Izitena ezakhiwe ngobume beArc zikwabizwa ngokuba zizitena zearc. Izitena eziphakamileyo ze-alumina arc ziluhlobo lwezitena ezimile okhethekileyo. I-arc yezitena ze-arc iyisetyhula kwaye elinye icala yindawo yokuhamba. , Ingakhiwa kwakhona kwisangqa, olu hlobo lwezitena lusetyenziswa kwiladle. Isitena se-arc sisetyenziswa ikakhulu njengombhobho wangaphakathi webhakethi yentsimbi. Ibikade iludongwe ikakhulu. Ngoku ngokuthe ngcembe indawo izitena eziphezulu zealumum. Izitena eziphakamileyo ze-alumina zibonakaliswa kukumelana okuhle kwe-thermal, ukumelana nokuqina komhlwa kunye namandla aphezulu okucinezelwa.

Izitena ezi-aluminium eziphezulu ze-arc ziqulathe i-aluminium silicate ene-Al2O3 ngaphezulu kwama-48% ukuya kuma-75%. Ukuphakama komxholo wealuminium, kokungcono umgangatho wezitena zealuminium eziphezulu. Yinto enqabileyo ene-asidi enqabileyo, eyenziwe ngezinto ze-alumina zendalo okanye ezingezizo (i-sillimanite, diaspore, alumina ephezulu, njl.). Xa kuthelekiswa nezitena zodongwe, ukubuyisela kwakhona (1750 ～ 1790 ℃) kunye nomthwalo wobushushu obuthambisayo (1420 ～ 1500 ℃) ziphezulu, kwaye ukuxhathisa kwe-slag kunye namandla acinezelayo nawo aphezulu.
