Yakakwira alumina yakasarudzika-yakaita zvidhinha
Yakakwira alumina yakasarudzika-yakaita zvidhinha
Zvidhinha zvakasarudzika zvakaomarara zvinokwanisa kumira zvakasiyana shanduko yemuviri uye yemakemikari uye mhedzisiro yemagetsi patembiricha yakakwira. Chidhinha chakasarudzika-chakaumbwa chinogadziriswa nechimwe chimiro uye saizi.
Zvidhinha zvakasarudzika zvakaomeswa zvinogona kukamurwa kuita zvidhinha zvinopiswa, zvidhinha zvisina kupera, zvakasanganiswa zvidhinha (zvakasanganiswa zvidhinha), uye zvinopikisa uye zvinopisa-zvidhina zvichienderana nemaitiro ekugadzirira. Pamusoro pezvo, zvidhinha zvakasarudzika-zvinokamurwa zvinogona kukamurwa kuita zvidhinha zvakajairika, zvidhinha zvakajairika, uye zvidhinha zvakaumbwa-zvinoenderana nechimiro uye saizi. Zvidhinha zvakasarudzika zvakaumbwa zvinogona kushandiswa seyakavakisa tembiricha zvekuvakisa uye zvemidziyo zvekuvaka kilns nemidziyo yakasiyana-siyana yekupisa.
Mutengo wezvidhinha zvakasiyana-siyana zvinoratidzika zvinoenderana nekuoma kwemaitiro ekugadzira uye izvo zvinhu zvezvidhinha zvinopesana. Kazhinji, vagadziri vanogadzirisa vanozokumbira mutengi kuti ape iyo yekutanga zvidhinha dhizaini pavanotora chakasarudzika-chakaumbwa chinokanganisa zvidhinha. Iwe unofanirwa kuziva kukona kwese, radian yega yega kana Kukora, kureba, kukwirira, nezvimwe zvemufananidzo wega wega. Naizvozvo, kana iwe uchifanira kubvunza nezve mutengo wezvidhinha-zvakaumbwa, ndapota ipa zvakadzama dhizaini dhizaini kana zvimwewo zvinoenderana, kuti tikwanise kukurumidza uye nenzira kwayo kuverenga mutengo wezvakakosha-zvakaumbwa zvinokanganisa zvidhinha zvako.
1. Refractoriness: Refractoriness inzvimbo yezvidhinha zvinodzivirira izvo zvinokwanisa kudzivisa kupisa kwakanyanya kusinga nyungudike panguva yekushandisa, uye ndechimwe chezviratidzo zvakakosha zvekuyedza mhando. Kana iyo refractoriness isina kukwirira, huwandu hwakawanda hwemvura inozogadzirwa mukati mezvidhinha nekuda kwetembiricha refu-refu panguva yekushandisa, izvo zvinoita kuti masonry ese aparadzwe nekunyungudika. Iyo dhigirii rekudzvanyirira zvinoenderana nemakemikari emaminerari ekuumbwa kwechinhu chisina kugadzirwa, iwo masvosve akaumbwa echinhu chisina kugadzirwa, uye viscosity yechikamu chemvura.
2. Takura tembiricha inodzikamisa Kazhinji, inoratidzwa netembiricha yeimwe huwandu hwekushomeka hunokonzereswa nezvidhinha zvinodzika pasi pechiremerwa che2 kilogiramu pamakiromita masendimita. Chikamu chegirazi chidiki, iyo crystallization inoumba sisitimu dhizaini uye chidhinha ine yakaderera porosity, uye mutoro unodzikamisa tembiricha yakakwira.
3. Kumanikidza simba patembiricha yemukati: inoratidza masimba echimiro ezvidhina zvinokanganisa uye nekugona kutakura zvimisikidzo zvakamira: zvine hukama hwakakura nekuramba kwezvidhinha kukanganisa uye kupesana. Iko kusimba kwesimba kunoenderana nezvinhu zvakaita sekuwanda kwechigadzirwa, kuumbwa kwechinhu chisina kugadzirwa uye nedhigirii rekusvina.
4. Ruregerero: Kushuva kune hukama hwakakura neyakagomarara kusagadzikana. Kurwisa kwe slag kudzvinyirira zvakanyanya kunoenderana nemakemikari zvivakwa zvezvinhu zvinokanganisa (acidic, alkaline, kwazvakarerekera). Zvidhinha zvevhu zvimwe zvine acidic zvinokanganisa zvinhu. Kuwedzera izvo zvemukati zve AL2O3 kunogona kuwedzera kupisa kweiyo corrosion kune acid uye alkaline slag. Izvo zvinhu zvine imwechete yemakemikari zvivakwa zvinowedzera nzvimbo yekubatana pakati pezvidhinha uye zvakaumbwa nesimbi yakanyungudutswa nekuda kweiyo porosity yakakura, kuitira kuti slag yakanyungudika ipinde mumuviri wezvidhinha kuburikidza neporera, uye iyo slag ngura yekudzivirira inoderedzwa. Iyo porosity inoenderana nezvinhu zvakaita seyakaumbika mapellets, huwandu hwehuwandu uye huwandu hwekunyungudika kwechigadzirwa chimwe chete.
5. Yasara mitsara shrinkage: iyo vhoriyamu inogadziriswa yezvinhu zvinokanganisa pakakwirira tembiricha apo mutsetse wakasara unodzikira. Nekuda kwekudziya kwenguva refu kwezvidhinha panguva yekushandisa, zvidhinha zvinowedzeredzwa, uye vhoriyamu inoderera, ichikonzera kutsemuka uye deformation yemuviri wevira. Nekuda kwekudzora kusara kwekudzikira, chigadzirwa chinofanira kudzingwa panokwana tembiricha.
