Yuav Ua Li Cas Los Ua Cov Ntawv Muag Los Ntawm Alumina

Kev tsim cov khoom txhuas ntawm alumina (al₂o₃) cuam tshuam ntau cov kauj ruam kev lag luam, suav nrog metallurgical expiness, electrolysis, thiab precision dov.

Ntawm no yog cov ncauj lus kom ntxaws hauv Lus Askiv:

1. Extracting alumina los ntawm Bauxite (Bayer txheej txheem) Alumina yog thawj zaug ua ke los ntawm cov txheej txheem Bayer: (xws li cov hlau oxource) (xws li cov hlau oxide) (xws li cov hlau oxide))

(2) nag lossis daus

2. Aluminium los ntawm electrolytic txo (cov cuab yeej-herult cov txheej txheem)
Txhuas oxide tau hloov mus rau hauv molten aluminium ntawm electrolysis:

Kev rhuav tshem: Al₂o₃ yog yaj nyob rau hauv Molten Cryolite (Na-₃alf₆) kom txo qis nws lub ntsiab lus melting (txog 950 degree).

Electrolysis: Ncaj tam sim no decomposes aluminium rau txhuas (cathergen) thiab oxygen (ancts (ancts) ua rau cov pa roj carbon dioxide).

Casting: Lub Molten Aluminium yog Tapped thiab nrum rau hauv kev cuam tshuam lossis cov ntawv txheeb xyuas ntxiv.

3. Quav ntawm kev Ingots rau hauv ntawv ci
Dov ntawm kev cuam tshuam rau hauv cov ntawv ci tuab (0. 006-0. 2 hli):

Kub Rolling: Qhov kev cuam tshuam yog rhuab thiab dov rau hauv cov phaj tuab (kwv yees {{mm).

Colding txias: cov ntawv txheeb cais yog ntxiv los ntawm kev siv tas li

Xov: Cov ntawv ci yog txiav txiav, coated (yog tias tsim nyog), thiab kuaj xyuas qhov tsis xws luag ua ntej ntim.

Mengjiang pab pawg tau raug tshwj xeeb hauv kev tsim cov khoom siv txhuas rau 17 xyoo, los ntawm alumina plug ntau lawm rau txhuas ntawv ci thiab lwm yam khoom sib sib sib nqus. Yog tias koj xav tau Txhuas Ntawv Nyiaj,Thov koj xav tiv tauj peb.
