Incazelo emfushane

I-Junsheng high-purity magnesium-aluminium spinel system isebenzisa i-alumina ephezulu yokuhlanzeka kanye ne-high-purity magnesium oxide njengezinto zokusetshenziswa, futhi i-sintered ekushiseni okuphezulu. Ngokusho kwezinhlobo ezahlukene zamakhemikhali, ihlukaniswe ngamamaki amathathu: i-SMA-66, i-SMA-78 ne-SMA-90. Uchungechunge Lomkhiqizo.

XHUMANA MANJE

Izici

• I-Junsheng high-purity magnesium-aluminium spinel inezici ezilandelayo:
• Ukumelana okuphezulu kwe-refractory;
• Ukuzinza kwevolumu yokushisa okuphezulu;
• Ukumelana okuhle kakhulu ne-alkaline slag corrosion kanye nokungena;
• Ukuzinza okuhle kokushaqeka okushisayo.

Amaminerali omgogodla anethonya elibalulekile ezindaweni zokushisa eziphezulu zezinto eziphikisayo. Isibonelo, ngenxa ye-coefficient encane yokunweba okushisayo kwe-spinel (α=8.9x10-*/℃ ku-100~900℃), i-spinel isetshenziswa njenge-ejenti ebophayo ( Noma ebizwa ngesigaba sikasimende, i-matrix), izitini ze-magnesia-alumina ezine-periclase. njengesigaba esiyinhloko se-crystal, lapho izinga lokushisa lishintsha kakhulu, ukucindezeleka kwangaphakathi okwenziwe kuncane, futhi izitini akulula ukuphuka, ngakho-ke ukuzinza okushisayo kwezitini kungathuthukiswa (izitini ze-magnesia-alumina Ukuzinza okushisayo yi-50 ~ 150 izikhathi).

Ngaphezu kwalokho, ngenxa yokuthi i-spinel inezakhiwo ezinhle ezinjengokuqina okuphezulu, izakhiwo zamakhemikhali ezizinzile, nendawo ephakeme yokuncibilika, futhi imelana kakhulu nokugqwala ngokuncibilika okuhlukahlukene emazingeni okushisa aphezulu, ukuba khona kwamaminerali e-spinel emikhiqizweni kuye kwathuthukisa ukusebenza kokushisa okuphezulu umkhiqizo.

Isizathu esiyinhloko esenza izinga lokushisa eliphezulu lokuthambisa izinga lokushisa lezitini ze-magnesia-alumina (indawo yokuqala ayikho ngaphansi kuka-1550-1580 ℃) liphakeme kunalelo lezitini ze-magnesia (indawo yokuqala ingaphansi kuka-1550 ℃) ukuthi ukwakheka kwe-matrix kuhlukile. .

Ukufingqa, ama-spinel ayizinto ezinhle kakhulu ngokwezinga lokuncibilika, ukunwetshwa okushisayo, ubulukhuni, njll., enezici zamakhemikhali ezizinzile, ukumelana okuqinile nokuguguleka kwe-alkaline slag, nokumelana nokuguguleka kwensimbi encibilikisiwe .Ukuqhathaniswa kwezakhiwo ze-spinel namanye ama-oxides. .

Ulwazi Oluyisisekelo

I-Junsheng high-purity magnesia-aluminium spinel inokuqukethwe kokungcola okuphansi kakhulu nokusebenza okuhle kakhulu kwezinga lokushisa eliphezulu. I-high-purity spinel ifaneleka ezingxenyeni ezakhiwe ngaphambili njengezitini eziphefumulayo, izitini zesihlalo, ama-ladles, izembozo eziphezulu zesithando somlilo kagesi, izinto eziphikisayo zama-rotary kilns, nezinto eziphikisayo zokuncibilikisa ama-alloys. imikhiqizo, kanye namasethi aqukethe i-spinel.

Imikhiqizo ingasiza ukuthuthukisa ukumelana nokugqwala kwe-slag kwezinto eziphikisayo, futhi ixazulule inkinga yokuqhekeka kwempahla okubangelwa ukwengeza izinto zokusetshenziswa ze-magnesium.
