Izitena eziphezulu ze-alumina ze-furnaces eziqhumayo zenziwe nge-bauxite yezinga eliphezulu njengeyona nto iphambili, ehlanganiswe, icinezelwe, yomiswe kwaye ifakwe kwiqondo lokushisa eliphezulu. Ziimveliso ezilahlayo ezisetyenziselwa ukufakwa kwi-lining furnaces.
1. Iimpawu ezibonakalayo kunye neekhemikhali zezitena eziphezulu ze-alumina

2. Ziphi izitena eziphezulu ze-alumina ezisetyenziswa kwiziko eliqhumayo?
Izitena eziphezulu ze-aluminium zakhiwe kwi-shaft yesithando somlilo we-blast furnace. I-furnace shaft ifumaneka kwindawo ephezulu yesithando somlilo. Ububanzi bayo buyanda ngokuthe ngcembe ukusuka phezulu ukuya ezantsi ukulungelelanisa nokwandiswa kwe-thermal yentlawulo kunye nokunciphisa ukungqubuzana kodonga lwesithando somlilo kwintlawulo. Umzimba wesithando somlilo uhlala kwiziko lomlilo. I-50% -60% yokuphakama okusebenzayo. Kule meko, i-furnace lining idinga ukuhlangabezana neemfuneko ezinjalo, kwaye iimpawu zezitena eziphezulu ze-alumina zi-refractoriness ephezulu, ubushushu obuphezulu bokuthambisa phantsi komthwalo, ukuxhathisa kwe-asidi, ukuxhathisa kwe-alkali, ukuchasana okunamandla kukhukuliseko lwe-slag, kunye nokumelana nokunxiba kakuhle. Inokwaneliseka, ngoko ifanelekile kakhulu ukuba umzimba wesithando somlilo ufakwe ngezitena eziphezulu ze-alumina.
Oku ngasentla sisingeniso kwizitena eziphezulu ze-alumina ukwenzela ii-furnaces eziqhumayo. Ubume be-lining of the furnace buyinkimbinkimbi kwaye kukho iintlobo ezininzi zezinto eziphikisayo ezisetyenzisiweyo. Izitena eziphezulu ze-alumina yenye yazo. Kukho iinkcukacha ezi-3-5 zezitena eziphezulu ze-alumina ezisetyenzisiweyo. Izitena eziphezulu ze-alumina zikaRobert zinokusetyenziswa kwiindidi ezahlukeneyo. Ukuba kuyimfuneko, nceda uqhagamshelane nathi.
