Yintoni indawo yokunyibilika izitena ezikhanyelayo?

Izitena ezixhathisayo zizinto ezikwazi ukumelana nobushushu, ezisetyenziswa kakhulu kwimisebenzi yobushushu obuphezulu obufana neetshimini kunye neekhilni. Nangona kunjalo, izitena eziphikisayo nazo zineendawo zokunyibilika. Iintlobo zezinto eziphathekayo zezitena eziphikisayo zihluke. Khetha uhlobo lwezitena eziphikisayo ngokomsebenzi wakho wokusebenzisa.

I-refractory eyenziwe ngodongwe olungatshiyo okanye ezinye izinto eziphikisayo. Ikakhulu isetyenziselwa ukwakha iziko lokunyibilikisa, inokumelana nobushushu obuphezulu be-1,580℃-1,770℃;

izitena zodongwe buthathaka imathiriyeli acidic refractory. Emva kokuba i-refractoriness yezitena zodongwe ezisetyenzisiweyo kwimizi-mveliso ingaphezulu kwe-1600 ° C, ukushisa kokuqala kokuthotywa kwemithwalo yi-1250-1300 ° C kuphela. Izitena zodongwe ezisetyenziswa kwiziko loshishino lweYiran zizityebi kakhulu kwizinto eziluhlaza, itekhnoloji yokuvelisa ilula, kwaye ixabiso liphantsi. Zisetyenziswa ngokubanzi kulwakhiwo lweziko zokufudumeza ezahlukeneyo zeYiran kunye neeflue, iitshimini, kunye neetshimini zeYiran zokunyanga ubushushu. Umzimba wesithando somlilo, izixhobo zokushisa inkunkuma kunye nezitshisi zenkqubo yokutshisa, njl.

I-Magnesia isitena yinto ephikisayo enomxholo we-MgO ngaphezu kwe-80-85% kunye ne-periclase njenge-deposit mineral primary. Indawo yokunyibilika yeMgO iphezulu ukuya kuma-2800℃. I-refractoriness yesitena se-magnesia ingaphezulu kwe-2000 ℃, kodwa indawo yayo yokuthambisa phantsi komthwalo iphantsi kakhulu, nje ngokuba yi-1500-1550 ℃. Oku kungenxa yokuba i-crystals ejikelezayo ejikelezayo idibaniswe yi-forsterite ephantsi-enyibilikayo (CaO·MgO · SiO2) kunye neglasi, ngelixa i-periclase ingenzi inethiwekhi ye-crystalline eqhubekayo, ukushisa kwe-deformation yomthwalo kuphantsi kakhulu, kwaye isiqalo Uluhlu lweqondo lokushisa ukusuka kwi-softening. ukuya kwi-40% deformation incinci kakhulu, nje ngo-30-50 ℃. Ukuzinza kwe-thermal yezitena ze-magnesia nazo zihluphekile, kwaye zivele ziqhekeke ngexesha lokupholisa ngokukhawuleza kunye nokufudumala, eyona nto ibalulekileyo emonakalweni wezitena ze-magnesia.

Izitena eziqhelekileyo ze-corundum zifanelekile ukufakwa kwindawo yomlilo we-oyile enzima ye-gasification ye-oil kunye noxinzelelo olusebenzayo lwe-3MPa okanye ngaphantsi, inxalenye ebalulekileyo ye-lining of incinerators yamanzi anetyuwa, kunye nezitena ezivuthayo ezivuthayo ezisebenza kumaqondo aphezulu okushisa. Ngokuqhelekileyo, ubushushu bokusetyenziswa kwezitena ze-corundum bungaphantsi kwe-1600-1670 degrees Celsius. Izitena zodongwe ezikhanyelayo ezilula zisetyenziswa njenge-kiln linings engagqwaliswanga yi-slag ephezulu yobushushu kunye neegesi ezidliwayo. Ngokuxhomekeke kumthamo, ubushushu bokusebenza buphakathi kwe-1150-1400 degrees Celsius

Oku ngasentla sisishwankathelo seendawo ezahlukeneyo zokunyibilika kwezitena eziphikisayo ngokweentlobo ezahlukeneyo. Xa ukhetha izitena eziphikisayo, unokukhetha kwakhona okulungileyo ngokubhekiselele kwindawo yokunyibilika.
