Zvidhinha zveCorundum/Zvidhinha zveCorundum Mullite
Ruzivo rweChigadzirwa
Zvidhinha zveCorundums zvigadzirwa zvinoramba kusimba zvine corundum sechikamu chikuru chekristalline, uye huwandu hwealumina hunodarika 90%.
Kupatsanura:Zvidhinha zveCorundum zvinonyanya kurongwa muzvikamu zviviri: zvidhinha zvecorundum zvakacheneswa uye zvidhinha zvecorundum zvakacheneswa. Chekutanga chakagadzirwa nealumina yakacheneswa, nepo chechipiri chakagadzirwa necorundum yakacheneswa. Zvidhinha zvecorundum zvisina kupiswa zvinogonawo kugadzirwa uchishandisa phosphoric acid kana zvimwe zvinosunga.
Hunhu hweKushanda:
Zvimiro Zvakanaka zveRefractory:Tembiricha inonyorovesa pasi pemutoro wezvidhinha zve corundum inodarika 1700°C, uye zvimwe zvidhinha zve chrome corundum zvinogona kusvika patembiricha inodarika 1790°C. Zvinoramba zvakagadzikana munzvimbo dzine tembiricha yepamusoro uye hazvikanganisike kana kukuvara.
Simba Rakakwirira:Simba rekudzvanya rezvidhinha zve corundum zvine purity yakawanda patembiricha yemumba rinowanzova 70MPa-100MPa, nepo zvidhinha zve chrome corundum zvine performance yepamusoro zvinodarika 150MPa uye zvinogona kusvika 340MPa.
Kugadzikana Kwakanaka Kwemakemikari:Zvidhinha zveCorundum zvinotsungirira zvakanyanya slags dzine acidic kana alkaline, simbi, uye magirazi akanyungudutswa, uye hazvikuvadzi makemikari.
Kuramba kwakasimba kukurwa kwevhu:Semuenzaniso, huwandu hweCr₂O₃ huri muzvidhinha zve chrome corundum hunodzivirira slag yakanyungudutswa kuti isapinde mumuviri wezvidhinha kuburikidza nemaburi e capillary, zvichikonzera kuramba kukuru kweslag kune zvidhinha zve corundum zvakajairika.
Zvinhu Zvikuru Nezvinhu Zvisina Kugadzirwa:
Chinhu chikuru chinoshandiswa pakugadzira zvidhinha zve corundum i alumina (Al₂O₃), inowanzo pfuura 90%, uye zvimwe zvine kusvika 99%. Zvinhu zvisina kugadzirwa zvinosanganisira sintered alumina uye fused corundum. Zvimwe zvinhu zvemineral zvinogonawo kuwedzerwa kuti zvigadzire zvinhu zvakasanganiswa, zvakaita seCr₂O₃ yezvidhinha zve chrome corundum uye ZrO₂ yezvidhinha zve zirconium corundum.
Zvidhinha zveCorundum-mullitezvidhinha zvinosanganisa zvinoramba kushanda zvine zvikamu zviviri zvinogara kwenguva refu: corundum (Al₂O₃) uye mullite (3Al₂O₃・2SiO₂). Zvinosanganisa simba guru re corundum nekudzivirira kupisa kwakanyanya kwe mullite, zvichiita kuti zvive zvinhu zvinopisa zvakanyanya zvinoenzanisa mashandiro uye kushanda zvakanaka kwemari.
Zvikamu Zvikuru uye Zvimiro zveMuumbi
Kuumbwa kweMain Crystalline Phase:Corundum ne mullite ndiwo ma crystal phases maviri makuru, ane alumina yakawanda kubva pa70% kusvika 90%, uye yasara inonyanya kuva silicon dioxide (SiO₂). Simba rekubatana kwezvikamu zviviri izvi rinoenzanisa mashandiro.
Magadzirirwo emukati memuviri:MaMullite phases anoparadzirwa pakati pemakoramu ecorundum muchimiro chemakristaro akaita setsono kana kuti columnar, zvichigadzira chimiro che "corundum skeleton + mullite connection". Izvi hazvingowedzere simba rezvidhinha chete asiwo zvinodzivirira kushushikana kwekupisa kuburikidza nepakati pemaganhu emakristaro madiki.
Zvakanakira Kushanda Kwakakosha
Kudzivirira kupisa kwakanyanya:Iri ndiro bhenefiti rayo guru. Mullite ine mwero wakaderera wekuwedzera kwekupisa, uye chimiro chayo chekristaro chakaita setsono chinotora kushushikana kunokonzerwa nekuchinja-chinja kwekupisa, zvichideredza zvakanyanya kupwanyika kunokonzerwa nekutonhora nekukurumidza uye kupisa pakupisa kwakanyanya. Kushanda kwayo kunodarika kwezvidhinha zvecorundum zvakachena.
Simba rakaenzana uye kuramba ngura:Kuvapo kwechikamu che corundum kunoita kuti pave nesimba rakawanda pakupisa kwemumba nepakupisa kwakanyanya, ukuwo zvichipa simba rakanaka pakuderedza acidic slag, girazi rakanyungudutswa, nezvimwe zvinhu. Kunyange hazvo simba rayo re alkali rakaderera zvishoma pane re chrome corundum bricks, inopa mashandisirwo akasiyana-siyana.
Kufambiswa kwemhepo nekupisa kuri pakati nepakati:Kana ichienzaniswa nezvidhinha zve corundum zvine density yakakura, inopa kufambiswa kwemhepo kwakaderera uku ichichengetedza mwero wakati wekudzivirira kupisa, ichideredza kurasikirwa nekupisa mumidziyo inopisa zvakanyanya uye zvichiita kuti ive yakakodzera kushandiswa kunoda kupindira kwemhepo inopisa.
