Isitini se-corundum esifakiwe

Izinzuzo zomkhiqizo: izinga lokushisa eliphakeme lokushisa okujwayelekile (kufika ku-340MPa), ukushisa okuphezulu kokuthambisa umthwalo (izinga lokushisa lokuqala lokuthambisa liphezulu kune-1700 ° C), ukuqina okuhle kwamakhemikhali, i-acid enhle ne-alkali slag, ukumelana nensimbi nengilazi.

Isicelo somkhiqizo: Ukusetshenziswa okuyinhloko kwezitini ezihlanganisiwe ze-corundum ngamabhodlela e-borosilicate glass, amabhande wokushisa asezingeni eliphakeme lokushisa, i-graphite yokuwasha izithandani ezisebenza ngomshini, iziko lokuncibilikisa insimbi elingeyona insimbi, njll. Izitini ze-α-β corundum ezisetshenzisiwe zisetshenziswa kakhulu isigaba sokucaciswa, isigaba sokupholisa, iphuli yokusebenza, njll. Ngaphezu kwalokho, izitini ezihlanganisiwe ze-α-β corundum nazo ziyasetshenziswa ophahleni nakwisakhiwo esingenhla seziko lengilazi, abagijimi abasabalalisi abasakaza ngokuqhubekayo kanye nojantshi we-furnace slide. Izitini ezihlanganisiwe ze-beta corundum zingasetshenziselwa kuphela ukwakheka okuphezulu kwesibuko sengilazi ngothuli lwe-SO2, njengesakhiwo esiphezulu sedamu elisebenzayo, udonga lwebele eduze kwesishisi, isibiseli sesithando somlilo esincane, udonga olulenga nokunye .

incazelo yomkhiqizo

Isigaba esikhulu se-crystal sesitini se-corundum esihlanganisiwe yi-corundum, futhi okuqukethwe kwe-Al2O3 ngokuvamile kuphakeme kune-93%. Ukumelana nokushaqeka okushisayo kwezitini ezihlanganisiwe ze-corundum kuhlobene kakhulu nomzimba. Imikhiqizo eminyene ye-corundum inokumelana okungcono kokugqwala, kepha ukumelana nokushaqeka okungampofu. Izitini ezihlanganisiwe ze-corundum zingahlukaniswa ngokwengeziwe zibe izitini ezihlanganisiwe ze-α corundum, izitini ezihlanganisiwe ze-α-β corundum nezitini ezihlanganisiwe ze- corundum.

Izici zezitini ezihlanganisiwe ze-corundum:

1.Ukucindezela okuphezulu ekamelweni lokushisa (kufika ku-340MPa)

2.Ukushisa okuphezulu kokuthambisa umthwalo (ukushisa kokuthambisa kokuqala kuphakeme kune-1700 ℃)

3. Ukuzinza okuhle kwamakhemikhali

4. Ukumelana okuhle ne-acid ne-alkali slag, insimbi encibilikisiwe nengilazi
