Ibhloko enganyangekiyo ye-alkali luhlobo lwesitena se-alumina esiphantsi, umxholo we-Al2O3 yi-30-25%, izinto eziphambili zeebhloko ezinganyangekiyo ye-alkali ludongwe olunganyangekiyo lwe-alumina oluphantsi, ibhloko yomlilo enganyangekiyo ye-alkali luhlobo lweemveliso ezinganyangekiyo ze-silicaalumina ezisebenza kakuhle ekuchaseni ukukhukuliseka kwe-alkali kwinkqubo ye-oven yesamente. Ibhloko enganyangekiyo ye-alkali inamandla aphezulu, uzinzo oluhle lomthamo, amandla okukhukuliseka kwe-alkali, njl. Ibhloko enganyangekiyo ye-alkali iyasebenza kwi-preheater ye-oven yesamente kunye ne-oven ebolayo.
Iimpawu zezitena ezimelana ne-alkali
- Ixesha elide lenkonzo,
- Udongwe lomlilo olucocekileyo kakhulu,
- ukumelana nokungena,
- Ukumelana okuhle kwe-alkali,
- Ukumelana okubalaseleyo kwe-alkali
- uzinzo oluhle lobushushu,
- Uncedo oluhle lokuhlasela ngeekhemikhali.
Inkqubo Yokuvelisa Izitena Ezingamelani Ne-Alkali
Izitena ezimelana ne-alkali zikwiqondo lobushushu eliphezulu, ezinokuthi zisabela kwi-alkali metal oxide eveliswe yi-viscosity ephezulu yesigaba solwelo, zenze umaleko we-glaze utshintshe imo, ugqume umphezulu we-block yezitena, ukuthintela ukungena kunye nokukhukuliseka kwezinto ezinyibilikisiweyo ze-alkali metal, injongo kukukhukuliseka kwe-alkali. I-block emelana ne-alkali ibhekisa kudongwe olumelana ne-alkali oluphantsi njengezinto eziphambili zokwenza, ezenziwe nge-aluminium kwinkqubo ye-oven yesamente kwaye zinokuxhathisa kakuhle ukugqwala kwe-alkali kunye nokuqhuba okuphantsi kobushushu.
Uhlu lweeBricks ezimelana neAlkali
Izitena ezimelana ne-alkali zinokwahlulwa zibe ziintlobo ezine: izitena eziqhelekileyo ezimelana ne-alkali, izitena zomlilo ezinamandla aphezulu ezimelana ne-alkali, izitena ezimelana ne-alkali ezimelana ne-vault kunye nezitena ezimelana ne-alkali ezimelana nobushushu.
Izitena eziqhelekileyo ezimelana ne-alkali zisetyenziswa kakhulu kwi-preheater ye-oven yesamente kunye ne-oven ebolayo kathathu.
Izitena zomlilo ezinamandla aphezulu ezimelana ne-alkali zisetyenziswa kakhulu kwi-preheater ye-oven yesamente, kwi-furnace ebolileyo, kwii-air ducts ezintathu, kwi-vertical rising flue, nakwi-cyclone cylinder.
Ibhloko enganyangekiyo ye-alkali yohlobo lwe-vault isetyenziswa kakhulu kwi-preheater ye-oven yesamente kunye ne-oven ebolayo kathathu.
Ibhloko ye-alkali enganyangekiyo yohlobo lwe-thermal insulation inokumelana okuhle nokugqwala kwe-alkali kunye nokuqhuba okuphantsi kobushushu, kwaye ine-insulation esebenzayo yobushushu yeemveliso ze-silica alumina ezichaseneyo.

Ukusetyenziswa kwezitena ezimelana ne-alkali
Izitena ezinganyangekiyo ze-alkali zinamandla aphezulu, zizinzile kakuhle, ziyakwazi ukukhukuliseka kwi-alkali. Izitena ezinganyangekiyo ze-alkali ziyasebenza kwi-preheater ye-oven yesamente kunye ne-oven ebolayo, i-air duct, njl. Izitena zomlilo ezinganyangekiyo ze-alkali zikwasetyenziswa kwinkqubo yokufudumeza i-Kiln, i-oven ebolayo, i-tertiary air duct.
Umenzi wezitena ezimelana ne-alkali ezivela kwi-RS Refractory Factory
Ifektri ye-RS refractory njengomvelisi weebhloko ezichasene ne-alkali eTshayina, ineenzuzo ezininzi zokhuphiswano kwimarike. Ukuba unesidingo sebhloko echasene ne-alkali, okanye unemibuzo malunga nezitena ezichasene ne-alkali malunga neempawu zomzimba nezekhemikhali, nceda unxibelelane nathi simahla, siza kukunika izitena ezichasene ne-alkali ezisemgangathweni ophezulu.
