2. A ina ake amfani da manyan bulogin alumina a cikin tanderun fashewa?

An gina tubalin aluminium masu tsayi a kan mashin tanderun tanderun fashewar. Wurin tanderun yana cikin ɓangaren sama na tanderun fashewar. Diamitansa a hankali yana faɗaɗa daga sama zuwa ƙasa don daidaitawa da haɓakar thermal na cajin kuma rage jujjuyawar bangon tanderun akan cajin. Jikin tanderun ya mamaye tanderun fashewar. 50% -60% na tsayi mai tasiri. A cikin wannan yanayi, rufin tanderu yana buƙatar saduwa da irin waɗannan buƙatun, kuma halaye na tubalin alumina masu tsayi suna da ƙarfi sosai, zafin jiki mai laushi a ƙarƙashin kaya, juriya acid, juriya na alkali, juriya mai ƙarfi ga yashwar slag, da juriya mai kyau. Ana iya gamsuwa, don haka yana da matukar dacewa da jikin wutar lantarki mai fashewa da za a yi shi da manyan tubalin alumina.

Abin da ke sama gabatarwa ne ga manyan tubalin alumina don tanderun fashewa. Wurin rufin tanderun fashewar yana da sarkakiya kuma ana amfani da nau'ikan nau'ikan abubuwan da ba a iya jurewa ba. Babban tubalin alumina na ɗaya daga cikinsu. Akwai ƙayyadaddun ƙayyadaddun 3-5 na manyan tubalin alumina da aka yi amfani da su. Ana iya amfani da tubalin alumina masu tsayi na Robert a cikin kiln iri-iri. Idan ya cancanta, da fatan za a tuntuɓe mu.
