Magnesia-Alumina Spinel Bricks: Mhinduro dzekudzivirira mashandiro epamusoro kumaindasitiri ane tembiricha yakakwira

Muchikamu chemaindasitiri chinopisa zvakanyanya, mashandiro emidziyo yekubikira muchoto anokanganisa zvakananga kushanda zvakanaka kwekugadzirwa uye kunaka kwechigadzirwa. Semumiriri wezvinhu zvinopisa zvakanyanya, magnesia-alumina spinel bricks, zvine hunhu hwazvo hwakanaka, zvave sarudzo yakakodzera kumaindasitiri akadai sesimbi, girazi, nesimende kudzivirira kukurwa kwemhepo zvakanyanya uye kuwedzera hupenyu hwemidziyo, zvichipa rutsigiro rwakavimbika rwekugadzirwa kweindasitiri kunopisa zvakanyanya.

Kutungamira Indasitiri neKushanda Kwakanaka Kwazvo

Zvidhinha zveMagnesia-alumina spinel zvinogadzirwa kubva kuMagnesia neAluminium oxide kuburikidza nemaitiro akakosha. Chimiro chazvo chakasiyana chekristaro chinoita kuti zvive nemabhenefiti akasimba ekushanda. Zvidhinha izvi zvinoratidza kusimba kwakanyanya pakupisa kwakanyanya, zvinokwanisa kutsungirira kupisa kwakanyanya kusvika 1800°C. Kunyangwe munzvimbo dzinopisa zvakanyanya kwenguva refu, zvinochengetedza hunhu hwakasimba hwemuviri nemakemikari, zvichidzivirira kukuvara kwemadziro echoto kunokonzerwa nekupisa kwakanyanya.

Kusabatwa nekupisa kwakanyanya chinhu chinoshamisa chezvidhinha zvemagnesia-alumina spinel. Munguva yekupisa nekutonhodza kwemakiln kakawanda, zvinhu zvakajairika zvinoramba zvichipwanyika uye zvinoputika nekuda kwekumanikidzwa kwekupisa. Zvisinei, nekuda kwekuwedzera kwavo kushoma kwekupisa uye kusimba kwakanaka, zvidhinha zvemagnesia-alumina spinel zvinogona kuderedza kukanganiswa kwekupisa, zvichideredza zvakanyanya njodzi yekukuvadzwa nekupisa, kuwedzera hupenyu hwebasa, uye kuderedza nguva yekusabatwa kwezvidhinha zvemakiln kuti zvigadzirwe.

Zvidhinha zveMagnesia-alumina spinel zvinoshandawo zvakanaka mukudzivirira kukurwa kwevhu nemakemikari. Zvine simba guru rekudzivirira kusvibiswa kwealkaline neacidic, pamwe chete nemagasi anodziya zvakanyanya, zvichidzivirira kupinda kwezvinhu zvinokuvadza uye kuchengetedza kuchengetedzeka kwemaovheni. Ingava munzvimbo ine alkaline yakawanda yekunyungudutsa simbi kana kuti munzvimbo ine acidic yakawanda yekugadzira magirazi, zvinogona kuita mabasa azvo ekudzivirira zvakadzikama.

Maitiro Akadzama Mumaindasitiri Akawanda

Muindasitiri yesimbi, zvidhinha zvemagnesia-alumina spinel zvinoshandiswa zvakanyanya munzvimbo dzakakosha dzema converters, ma ladles, uye tundishes. Munguva yekugadzira simbi dzema converter, zvinogona kutsungirira kukweshwa nekukukurwa kwesimbi yakanyungudutswa inopisa uye slag, zvichiita kuti converter lining irambe yakasimba. Kana zvikashandiswa muma ladles nema tundishes, zvinogona kuderedza zvinobudirira kusangana pakati pesimbi yakanyungudutswa nezvinhu zve lining, kuvandudza kuchena kwesimbi yakanyungudutswa, uye kuwedzera kunaka kwesimbi. Mushure mekunge kambani huru yesimbi yatora magnesia-alumina spinel bricks, hupenyu hwema ladles ayo hwakawedzera kubva paavhareji ye60 heats kusvika 120 heats, zvichideredza zvakanyanya mari yekugadzira.

Muindasitiri yekugadzira magirazi, zvidhinha zvemagnesia-alumina spinel ndizvo zvinonyanya kufarirwa pakugadzira zvikamu zvakakosha zvemagirazi. Munzvimbo dzinopisa uye dzinogadzirisa magirazi anonyungudutsa, zvinogona kutsungirira kuputsika kwegirazi rinonyunguduka uye kutsvairwa kwemagasi anodziya, kuchengetedza kugadzikana kwechimiro chekinu, kuderedza nguva yekuchengetedza kinu, uye kuvandudza kuenderera mberi nekugadzikana kwekugadzirwa kwegirazi. Mushure mekushandisa zvidhinha zvemagnesia-alumina spinel, kutenderera kwekugadzirisa magirazi egirazi kunogona kuwedzerwa nemakore maviri kusvika matatu, zvichiwedzera mabhenefiti ehupfumi emabhizinesi.

Munguva yekugadzira simende, nzvimbo inopisa zvakanyanya yemakiln anotenderera inoisa zvinodiwa zvakanyanya pazvinhu zvinoramba kushanda. Nekusimba kwazvo pakupisa, kuramba kukwesha, uye kugadzikana kwakanaka kwemakemikari, magnesia-alumina spinel bricks inoita basa rakakosha munzvimbo yekuchinja uye nzvimbo yekupisa yemakiln anotenderera, ichivimbisa kushanda kwakasimba kwemuviri wekiln mumamiriro ekupisa kwakanyanya uye mutoro wakawanda uye ichibatsira mukuwedzera kugadzirwa kwesimende uye kunaka kwemhando.

Gwaro Rekutenga reNyanzvi

Pakusarudza zvidhinha zvemagnesia-alumina spinel, zvinhu zvinotevera zvinofanira kusimbiswa: Chekutanga, nyatsoteerera kuumbwa kwemakemikari uye kuumbwa kwezvicherwa zvezvinhu. Magnesia nealuminium oxide zvakachena zvakanyanya zvinogona kuve nechokwadi chekuti zvidhinha zvinoshanda zvakanaka. Chechipiri, tarisa pane zviratidzo zvekushanda kwezvigadzirwa, zvakaita sehuwandu hwakawanda, porosity inooneka, uye simba rekupwanya rinotonhora patembiricha yemumba. Izvi zviratidzo zvinoratidza zvakananga kunaka uye kugara kwenguva refu kwezvidhinha. Chechitatu, ongorora maitiro ekugadzira uye sisitimu yekudzora mhando yevatengesi. Sarudza vatengesi vane michina yekugadzira yepamusoro, maitiro ekuongorora akakwana, uye ruzivo rwakakura muindasitiri kuti uve nechokwadi chekuti chigadzirwa chakavimbika. Pamusoro pezvo, zvichienderana nemamiriro chaiwo ekushanda, kururama kwehukuru uye kuchinjika kwechimiro chezvidhinha zvinodawo kufungwa kuti zvive nechokwadi chekuvakwa nekuiswa zvakanaka.

Nekushanda kwavo kwakanaka uye kushandiswa kwavo kwakakura, magnesia-alumina spinel bricks ave zvinhu zvisingakoshi zvinoramba kushanda zvakanaka mumaindasitiri anodziya zvakanyanya. Ingava iri kuvandudza kushanda zvakanaka kwekugadzira, kuderedza mitengo, kana kuona kuti chigadzirwa chakanaka, vanogona kupa mhinduro dzakavimbika kumabhizinesi. Bata nesu izvozvi kuti uwane ruzivo rwehunyanzvi rwechigadzirwa uye masevhisi akagadzirirwa iwe, uye ngatichengetedzei kugadzirwa kwako kwemaindasitiri kunodziya zvakanyanya!
