Maitiro Ekusarudza Magnesia Chrome Bricks Zvichibva paKiln Characteristics

Zvidhinha zveMagnesia chromeZvinhu zvakakosha zvinodzivirira maovheni anodziya zvakanyanya, anoshandiswa zvakanyanya mumaovheni anotenderera esimende, maovheni ekugadzira simbi, maovheni esimbi asina feri uye maovheni egirazi. Kushanda kwawo kunosarudza zvakananga hupenyu hweovheni, kushanda zvakanaka uye kuchengetedzeka kwekugadzirwa. Kuti usarudze zvidhinha zvemagnesia chrome zvakakodzera, unofanirwa kuenderana zvizere nehunhu hweovheni hwekushanda—iyi ndiyo kiyi yekuderedza mari yekugadzirisa uye kuwedzera mabhenefiti ekushanda.

Kutanga, tarisa pakupisa kwechoto. Machoto akasiyana ane zvinodiwa zvakasiyana-siyana pakupisa: nzvimbo dzinopisa simende dzinotenderera dzinosvika 1500–1650°C, nepo machoto emagetsi ekugadzira simbi anogona kudarika 1700°C. Zvidhinha zvemagnesia chrome zvemhando yepamusoro zvinofanirwa kunge zvine refractoriness inodarika 2000°C uye tembiricha inonyorovesa mutoro inodarika 1550°C kuti zvirambe zvakagadzikana pasi pekupisa kwakanyanya kwenguva refu. Kune machoto anodziya zvakanyanya, sarudza zvidhinha zvemagnesia chrome zvakagadziriswazve zvine kugadzikana kwakanaka pakupisa kwakanyanya.

Chechipiri, funga nezvenzvimbo yemakemikari muchoto. Zvinhu zvekugadzira alkaline muchoto (senge simende clinker) zvinoda zvidhinha zvine simba rekudzivirira alkali, nepo izvo zvinobata simbi yakanyungudutswa kana acidic slag zvinoda simba rakanaka rekudzivirira ngura. Magnesia (MgO) muzvidhinha zvemagnesia chrome inopa simba rekudzivirira alkali, nepo chromium oxide (Cr₂O₃) inowedzera simba rekudzivirira acid, zvichiita kuti zvikodzere nzvimbo dzakaoma dzemakemikari. Kune machoto ane slag erosion inowanzo shandiswa, sarudza zvidhinha zvine porosity shoma (porosity <20%) kudzivirira kupinda kweslag.

Chechitatu, ongororai kuramba kupisa nekuda kwekuchinja-chinja kwekupisa. Makilni ane ma "start-stop" anowanzo tanga (akadai se "non-ferrous melting furnaces") anoda zvidhinha zvinogona kumira nekukurumidza kuchinja kwekupisa pasina kutsemuka. Zvidhinha zve "semi-rebonded magnesia chrome" zvinopa kuramba kupisa kwakanaka, zvichiita kuti zvive zvakanaka mumamiriro ezvinhu akadaro, nepo mhando dzakasungirirwa zvakananga dzichienzanisa mashandiro uye mutengo wemakilnins ane kupisa kwakagadzikana.

Pamusoro pezvo, enzanisa rudzi rwezvidhinha nenzvimbo dzakatarwa dzechitofu. Kune nzvimbo dzinonyanya kusakara dzakadai semiromo yechitofu kana mitsetse yeslag, sarudza zvidhinha zvine simba guru zvine simba rekupwanya rinotonhora ≥35MPa. Kune mitsetse inogara iripo, zvidhinha zve common magnesia chrome zvinodhura zvishoma zvinoshanda zvakanaka, nepo mitsetse yekushanda yakakosha ichida mhando dzemhando yepamusoro dzakatwasuka kana dzakagadziriswazve.

Kusarudza zvidhinha zvemagnesia chrome zvakanaka hakusi kwemhando yezvinhu chete—kungoenderana nechimiro chekinu. Zvidhinha zvedu zvemagnesia chrome zvemhando yepamusoro, zvinowanikwa mumhando dzakasiyana-siyana uye saizi dzakagadzirwa, zvakagadzirwa kuti zvigutse zvinodiwa zvekinu zvakasiyana-siyana, zvichiita kuti chive chinoshanda kwenguva refu uye chishande zvakanaka. Taura nesu nhasi kuti uwane mhinduro yakagadzirirwa kinu yako.
