Yakaomeswa corundum zvidhinha
Yakaomeswa corundum zvidhinha
Zvigadzirwa zvigadzirwa: yakakwira yakajairwa tembiricha inomanikidza simba (inosvika ku340MPa), yakanyanya kuremedza tembiricha (tembiricha yekutanga yekunyorova yakakwira kupfuura 1700 ° C), kugadzikana kwemakemikari kwakanaka, yakanaka acid uye alkali slag, yakanyungudutswa simbi uye girazi kuramba.
Chigadzirwa chishandiso: Iko kushandiswa kukuru kwezvakaomeswa α corundum zvidhinha borosilicate girazi kilns, yakanyanya-tembiricha tanera yezvidhinha sintering mabhandi, graphite yekugocha choto inoshanda linings, isina-ferrous simbi yekuyera vira, nezvimwewo Fused α-β corundum zvidhinha zvinoshandiswa zvakanyanya mu kujekesa chikamu, kutonhora chikamu, kushanda dziva, nezvimwe zvegirazi kilns. Uye zvakare, fused α-β corundum zvidhinha zvinoshandiswa zvakare mudenga uye yepamusoro chimiro chegirazi mafira, inoenderera ichikanda yekuparadzira vanomhanya uye yekupisa yevira slide njanji. Yakavhenganiswa beta corundum zvidhinha inogona chete kushandiswa kune yepamusoro chimiro cheiyo girazi yezvidhinha neSO2 guruva, senge yekumusoro dhizaini rinoshanda, rusvingo rwechipfuva padyo nechopisa, chinopisa chediki diki, rusvingo rwakarembera zvichingodaro .
chigadzirwa tsanangudzo
Chikamu chikuru chekristaro chefused corundum zvidhinha ndeye corundum, uye zvirimo zveAl2O3 zvinowanzo kwirira kupfuura 93%. Iyo yekupisa yekuvhunduka kuramba kweyakavhenganiswa corundum zvidhinha zvakabatana zvakanyanya nemuviri. Dense corundum zvigadzirwa zvine zviri nani ngura kuramba, asi yakashata yekupisa yekuvhunduka kuramba. Fused corundum zvidhinha zvinogona kupatsanurwa kuita fused α corundum zvidhinha, zvakasanganiswa α-β corundum zvidhinha uye zvakasanganiswa β corundum zvidhinha.
Hunhu hwe fused corundum zvidhinha:
1. Yakakwira compressive simba pakamuri tembiricha (inosvika 340MPa)
2. Yakakwira mutoro inodzikamisa tembiricha (yekutanga kudzikamisa tembiricha yakakwira kupfuura 1700 ℃)
3. Kugadzikana kwakanaka kwemakemikari
4. Kwakanaka kuramba asidi uye alkali slag, yakaumbwa nesimbi negirazi
