Zvidhinha zveCorundum
Zvidhinha zveCorundumchigadzirwa chinogadzirisa kupisa kwakanyanya chine corundum sechikamu chikuru chekristalline, chinoshandiswa zvakanyanya muminda yemaindasitiri inodziya zvakanyanya. Chinofarirwa nemaindasitiri akasiyana-siyana nekuda kwekudzivirira kupisa kwakanyanya, simba remakanika uye kugadzikana kwemakemikari. Pazasi pane sumo yakadzama yezvidhinha zvedu zve corundum, kusanganisira kupatsanurwa kwechigadzirwa, hunhu hwekushanda, kuumbwa kwemakemikari, minda yekushandisa uye zvakanakira chigadzirwa.
Kurongwa Kwechigadzirwa
Zvichienderana nemakemikari (zvimwe zvinhu zvakawedzerwa) kana zvinhu zvakabikwa, zvidhinha zve corundum zvinonyanya kukamurwa kuita zvikamu zvina, chimwe nechimwe chine hunhu hwakasiyana uye mamiriro ekushandiswa akanangana nezvinodiwa zvakasiyana-siyana zvemaindasitiri.
1. Chidhinha cheCorundum Chena
Mazwi Akakosha:Kuchena Kwakanyanya, Kusachena Kwakaderera, Kupisa Kwakanyanya
Zvimiro zveSimba:Yakagadzirwa nealumina yemumaindasitiri, ine huwandu hushoma hwekusvibiswa (kunyanya huwandu hushoma hwesimbi), saka ine chena. Inodzivirira zvakanyanya uye ine simba remagetsi rinopisa zvakanyanya, uye ine kugadzikana kwakanyanya kwemakemikari pakati pezvidhinha zve corundum.
Zviri Mukati meAl₂O₃:≥ 99%
2. Chidhinha chebrown corundum
Mazwi Akakosha:Inodhura Zvikuru, Chinangwa Chayo, Inodzivirira Kupararira Kwemvura
Zvimiro:Yakanyungudutswa kubva mubauxite muchoto chemagetsi, ine iron oxide shoma (inoratidza brown). Inoratidzwa nechimiro chayo chakakora, inodzivirira kupisa kwemvura zvakanyanya, uye mutengo wayo uri nani kana tichienzanisa nezvidhinha zvecorundum chena.
Zviri Mukati meAl₂O₃:≥ 95%
3. Chidhinha cheChrome Corundum
Mazwi Akakosha:Kuramba Kuora, Kin yeGirazi, Kin yeSimende
Zvimiro:Chromite kana chromium oxide inowedzerwa mu corundum. Chinhu chikuru chayo ndechekudzivirira kukuru kumedurwa kwegirazi nekupwanyika kweslag, uye kudzivirira kupisa kwakanyanya panguva imwe chete.
Zviri Mukati meAl₂O₃:90-95%
4. Zirconia Corundum Brick
Mazwi Akakosha:Kuramba Kupfeka, Kugadzikana Kwekupisa, Rusvingo rweGirazi reFirnace
Zvimiro:Zircon inowedzerwa. Kuwedzerwa kwechikamu chezircon kunovandudza zvikuru kuramba kwechinhu ichi kupfeka uye kugadzikana kwekupisa (kuramba kutonhora nekukurumidza uye kupisa).
Zviri Mukati meAl₂O₃:60-80% (+ ZrO₂)
Hunhu hweKushanda:
Sechinhu chinodzivirira kushanda zvakanaka, zvidhinha zve corundum zvine hunhu hwakanaka kwazvo, uye mhando dzakasiyana dzezvidhinha zve corundum dzinowedzera kushanda kwakanangwa zvichibva pane zvataurwa pamusoro apa:
1. Kusasimba Kwakanyanya:Kusasimba kwechinhu ichi kunogona kusvika pamusoro pe1750℃, uye zvimwe zvigadzirwa zvine kuchena kwakanyanya (senge chidhinha checorundum chena) zvinogona kutsungirira tembiricha refu kwenguva refu pamusoro pe1800℃, zvichichengetedza kugadzikana munzvimbo dzine tembiricha yepamusoro pasina kuchinja kana kukuvara.
2. Simba Rakakwirira:Ine simba rekudzvanya rakakwira kusvika pakupisa kwemukamuri, kusvika ku340MPa, uye inogona kutakura zvinhu zvemakanika kana tembiricha yakakwira. Pakati pazvo, chidhinha chena checorundum chine simba guru remakanika rinopisa zvakanyanya.
3. Kugadzikana Kwakanaka Kwemakemikari:Inodzivirira zvakasimba slag ine acidic kana alkaline, simbi, girazi rakanyunguduka, nezvimwewo, uye haisi nyore kuita makemikari. Chidhinha chena checorundum chine makemikari akasimba nekuda kwekuchena kwaro kwakanyanya.
4. Kuramba Kusina Tsvina Yakanaka Uye Kuramba Kukukurwa Kwevhu:Zvikurukuru, inodzivirira zvakasimba slags dzakanyungudutswa dzine acidic, neutral uye alkaline. Chidhinha cheChrome corundum chinonyanya kushanda zvakanaka, izvo zvinogona kuwedzera hupenyu hwebasa racho.
5. Kugadzikana Kwakanaka Kwekupisa:Kunyangwe zvisina kunaka sezvimwe zvinhu zvine silicon kana magnesia, zvinogona kuvandudzwa zvakanyanya nekuwedzera zircon (yakadai se zirconia corundum brick) kana kugadzirisa particle gradation. Zirconia corundum brick ine thermal shock stability yakanyanya.
Zvidhinha zveCorundum-mullitechigadzirwa chemhando yepamusoro che refractory chine corundum ne mullite sezvikamu zvikuru zve crystalline. Nekuda kwekubatana kwezvikamu zviviri zvikuru, chinobatanidza corundum nekudzivirira kupisa kwakanyanya uye kuramba ngura nekugadzikana kwakanaka kwe mullite nekupisa kwakanyanya. Chigadzirwa ichi chinozivikanwa zvakanyanya muminda yepasi rose yemaindasitiri ane kupisa kwakanyanya senge simbi, magirazi, petrochemicals, uye kugadzirwa kwe carbon black, zvichipa mhinduro dzakavimbika dze lining components dzekiln uye zvichivandudza zvakanyanya kushanda kwemidziyo uye hupenyu hwebasa.
Zvakanakira Kushanda Kwakakosha:
1. 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 kutsemuka kunokonzerwa nekutonhora nekukurumidza uye kupisa pakupisa kwakanyanya. Kushanda kwayo kunodarika kwezvidhinha zvecorundum zvakachena.
2. 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.
3. Kufambisa kwekupisa 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 kuvharwa kwemhepo inopisa.
