Yakadzika inokwira yakakwirira alumina zvidhinha

Yakadzika inokwira yakakwirira alumina zvidhinha rudzi rweakakwira alumina zvidhinha izvo zvinopesana nemhando yepamusoro tembiricha kupfuura zvimwe zvigadzirwa zvakafanana, zvinogona kuchengetedza coke kushandiswa uye kuwedzera simbi kuburitsa. Iko kudzvanyirira kweakakwira alumina zvidhinha kwakakwirira kupfuura izvo zvevhu zvidhinha uye semi-silika zvidhinha, inosvika 1750 ~ 1790 ℃, iri yemhando yepamusoro yekuratidzira zvinhu. Yakadzika inokwira uye yakakwirira alumina zvidhinha zvakavakirwa pane “matatu-matombo” dzidziso. Sarudza bauxite uye rakasungwa ivhu seyakanyanya mbishi zvigadzirwa, wedzera yakakodzera kyanite, andalusite uye sillimanite, inowanzozivikanwa se “matombo matatu”, chengetedza muviri uye makemikari zviratidzo uye chidimbu kuumbwa, shandisa bauxite + mullite + corundum uye zvimwe mbishi zvinhu sehunyanzvi hurongwa . Mukugadzirwa kwekugadzira, zviratidzi zvezvinhu zvakasvibirira zvinotanga kuonekwa nekudzorwa. Mushure mekupwanya, kupwanya, uye kuongorora, izvo zvinongedzo zvakaenzana zvinoenderana neyakaenzana. Mushure mekusanganisa nekukuya, iyo saizi kukura uye hunyoro hwevhu rinodzorwa kusangana nezvinodiwa pakuumba. Anokodzera mabrasives anogona kudzora huwandu hwekurohwa, zviyero uye kupenya kweiyo kuumbwa, nepo uchiyedza semi-apedza zvigadzirwa uye kugona kusangana nezvinotsanangurwa. Dhizaini yekugadzira: shandisa yakanyanya-tembiricha yakavharirwa super bauxite, wedzera yakanyanya-tembiricha zvinhu ine yakaderera zvinofamba chiyero, uye unopinda yakakwira-kumanikidza kugadzira uye yakakwira-tembiricha sintering. Iine hunhu hwesimba rakakwira, yakadzika zvinokambaira uye yakanyanya kushanda tembiricha. Inoshandiswa zvakanyanya muvira rekuvira uye zvidhinha zvekutarisa tembiricha yepamusoro uye inopisa kupisa mafesi.

Zvichemo zveMikirwo:

1. Low creep rate uye diki tembiricha yakakwira inokwira.

2. Mutoro wekutapudza mutoro wakakwira.

3. Zvakanaka kukanganisa kusagadzikana.

4. Kupisa kwepamusoro uye simba rekumanikidza.

5. Yakanaka vhoriyamu kudzikama pakakwirira tembiricha uye yakanaka yekupfeka kuramba.

6. Kwakanaka ngura kuramba.

Nekuti yakakwirira-alumina inogadziriswa yezvidhinha zvigadzirwa ine yakakwira Al2O3, isina kusviba uye girazi risingabvumike zvishoma, tembiricha inodzikamisa mutoro iri pamusoro kupfuura yezvidhinha zvevhu, asi nekuda kwekuti mullite makristasi haagadzi mamiriro ehuneti, mutoro unopfavisa tembiricha ichiri isiri silica zvidhinha. kumusoro.

Yakadzika inokwira uye yakakwirira alumina zvidhinha zvine zvimwe Al2O3, iri padhuze nekusarerekera zvinhu zvinopesana, uye inogona kudzivisa kukukurwa kweasidhi slag uye alkaline slag. Sezvo iine SiO2, kugona kurwisa alkaline slag haina kusimba pane iyo yeasidhi slag.

Kushandiswa Kwemagetsi:

Zvidhinha zvakadzika zvinokwira-alumina zvidhinha zvinogadzirwa neyakaenzana giredhi bauxite inonamira seyakanyanya mbishi zvinhu, inowedzerwa neakasarudzika ekuwedzera. Mushure mekumanikidza-kwepamusoro uye kupisa kwepamusoro-tembiricha, ivo vane zvakanakira hombe yekuchengetedza kupisa kugona uye yakaderera zvinofamba. Ivo akakodzera kune madiki uye epakati blast mavira. Chitofu chemhepo inopisa.

Yakadzika inokwira uye yakakwira alumina zvidhinha zvekuputika mafesi uye inopisa blast mafesi anoshandiswa pakufuridza choto tepe chiteshi. Iyo inotakurika sisitimu inotora AI2O3-SiC-C akateedzana. Iyo ine yakanakisa maitiro eiyo ngura kuramba, kukosora kusagadzikana uye kwakanyanya kudziya kutsiga. Iyo inogona kuiswa kune yakakosha chiteshi ye blast mavira. Hot simbi mutsetse, slag mutsetse, swing kamwene, residual yesimbi tangi, pamusoro peiyo huru gomba rekuvhara, mativi ese maviri makuru gomba rekuvhara, esimbi gomba, slag gomba, etc.
