Mitundu Ndi Njira Zogwiritsira Ntchito Zopangira Zopangira Zopangira Mafakitale Osungunuka

Waukulu matenthedwe zida zang'anjo yosungunuka ya mafakitalezikuphatikizapo calcination ndi sintering ng'anjo, electrolytic thanki nding'anjo yosungunuka.Mzere woyatsira moto wa ng'anjo yozungulira nthawi zambiri umamangidwa ndi njerwa za aluminiyamu wapamwamba kwambiri, ndipo njerwa zadothi zimatha kugwiritsidwa ntchito ngati zokutira mbali zina.Chingwe cha refractory fiber chimayikidwa pazitsulo zotchingira kutentha pafupi ndi chigoba cha ng'anjo, kenako njerwa zopepuka kapena njerwa zopepuka zimamangidwa.Quality refractory castable kuthira.

Chigoba cha cell electrolytic chimapangidwa ndi mbale yachitsulo, ndipo wosanjikiza wa board of insulation or refractory fiber imayikidwa mkati mwa chipolopolo, kenako njerwa zopepuka zimamangidwa kapena kutsanuliridwa zonyezimira zopepuka, kenako njerwa zadothi zimamangidwa kuti zitheke. kupanga wosanjikiza wosagwira ntchito, ndipo selo la electrolytic limagwira ntchito Zosanjikiza zimatha kupangidwa ndi kaboni kapena silicon carbide refractory zida zokhala ndi magetsi abwino, kuti athe kukana kulowa kwa aluminiyamu yosungunuka ndi kukokoloka kwa fluoride electrolyte.M'mbuyomu, gawo logwira ntchito la khoma la cell ya electrolytic cell nthawi zambiri limamangidwa ndi ma carbon blocks.M’zaka zaposachedwapa, Japan ndi mayiko ena a Kumadzulo kwa Ulaya agwiritsira ntchito njerwa za silicon carbide kuphatikiza ndi silicon nitride pomanga, ndipo apeza zotsatira zabwino.

Gawo logwira ntchito pansi pa cell electrolytic nthawi zambiri limamangidwa ndi midadada ya kaboni yokhala ndi mfundo zing'onozing'ono ndipo imadzazidwa ndi phala la kaboni kuti asalowetse njira ya aluminiyamu ndikuwonjezera kuwongolera.

Zomwe zimagwiritsidwa ntchito kwambiri ndi aluminiyumuzida zosungunulirandi ng'anjo yowombolera.Mng'anjo ya ng'anjo yokhudzana ndi yankho la aluminiyumu nthawi zambiri imamangidwa ndi njerwa za aluminiyamu zapamwamba zomwe zili ndi A1203 80% -85%.Mukasungunula aluminiyumu yachitsulo choyera kwambiri, njerwa za mullite kapena njerwa za corundum ziyenera kugwiritsidwa ntchito.M'mafakitale ena, njerwa za silicon carbide zophatikiza ndi silicon nitride zimagwiritsidwa ntchito pomanga pazigawo zomwe zimatha kukokoloka ndi kutha, monga malo otsetsereka a moto ndi zida zotayira za aluminiyamu.Njerwa zodzimanga zokha kapena za silicon nitride zomangira silicon carbide zimagwiritsidwanso ntchito ngati zomangira ndi njerwa za zircon.Pakutsekeka kwa aluminium, zotsatira za vacuum cast refractory fiber ndizabwinoko.Zomangira za ng'anjo zomwe sizimalumikizana ndi aluminiyamu nthawi zambiri zimamangidwa ndi njerwa zadongo, zomangira zadongo kapena mapulasitiki okana.Pofuna kufulumizitsa kusungunuka ndikupulumutsa mphamvu, njerwa zopepuka, zotayira zopepuka zopepuka komanso zinthu zopangira ulusi wa refractory zimagwiritsidwa ntchito ngati zigawo zotchingira kutentha.

Aluminium smelting induction crucible ng'anjo imagwiritsidwanso ntchito kwambiri.Chingwecho nthawi zambiri chimapangidwa ndi aluminiyamu yapamwamba kwambiri yotchinga kapena yotchinga ramming yokhala ndi A1203 yokhala ndi 70% -80%, ndipo konkire ya corundum refractory imagwiritsidwanso ntchito ngati chitsulo.

Aluminiyamu wosungunuka amatuluka kuchokera mu ng'anjo ya aluminiyumu kudzera mu thanki yotulutsa aluminiyamu.Matanki nthawi zambiri amapangidwa ndi njerwa za silicon carbide, ndipo palinso midadada yopangidwa kale ndi mchenga wa silika wosakanikirana.Ngati chipika chokonzedweratu chimagwiritsidwa ntchito ngati akalowa thanki, pamwamba ayenera yokutidwa ndi anasakaniza silika mchenga kapena Gwiritsani mkulu aluminiyamu simenti anasakaniza silika mchenga refractory castable ngati wosanjikiza zoteteza.
