Izindaba

Izitini eziphakeme ze-alumina zezithando zomlilo zenziwe nge-bauxite yezinga eliphezulu njengezinto ezibonakalayo eziyinhloko, ezihlanganiswa, zicindezelwe, zomisiwe futhi zishiswe ekushiseni okuphezulu. Ziyimikhiqizo ephikisayo esetshenziselwa ulwelwesi lwezithando zomlilo.

1. Izinkomba ezingokwenyama namakhemikhali zezitini eziphakeme ze-alumina

2. Ziphi izitini eziphakeme ze-alumina ezisetshenziswa ezithandweni eziqhumayo?

Izitini eziphezulu ze-aluminium zakhiwe ku-shaft yesithando somlilo we-blast furnace. I-shaft yesithando somlilo itholakala engxenyeni engenhla yesithando somlilo. Ububanzi bayo bukhula kancane kancane ukusuka phezulu kuye phansi ukuze buvumelane nokwanda okushisayo kweshaja futhi kunciphise ukungqubuzana kodonga lwesithando somlilo ekushajeni. Umzimba wesithando somlilo uthatha isithando somlilo. 50% -60% wobude obusebenzayo. Kule ndawo, uhlaka lwesithando somlilo ludinga ukuhlangabezana nezidingo ezinjalo, futhi izici zezitini eziphakeme ze-alumina ziyi-refractoriness ephezulu, izinga lokushisa eliphezulu lokuthambisa ngaphansi komthwalo, ukumelana ne-asidi, ukumelana ne-alkali, ukumelana okuqinile nokuguguleka kwe-slag, nokumelana okuhle kokugqoka. Inganeliseka, ngakho-ke ifaneleka kakhulu ukuba umzimba wesithando somlilo ufakwe izitini eziphakeme ze-alumina.

Okungenhla yisingeniso sezitini eziphakeme ze-alumina zamaziko aqhumayo. Imvelo yomugqa wesithando somlilo iyinkimbinkimbi futhi kunezinhlobo eziningi zezinto eziphikisayo ezisetshenziswayo. Izitini eziphakeme ze-alumina zingenye yazo. Kukhona ukucaciswa okungu-3-5 kwezitini eziphakeme ze-alumina ezisetshenzisiwe. Izitini eziphakeme ze-alumina zikaRobert zingasetshenziswa ezindaweni ezihlukahlukene zokushisa. Uma kunesidingo, sicela usithinte.
