Cov txheej txheem ntau lawm ntawmaluminium hlauFeem ntau suav nrog cov kauj ruam hauv qab no: cov khoom siv raw khoom, smelting, extrusion, kos duab, kho deg thiab ntim. cov
Cov khoom siv raw khoom: Kev tsim cov txhuas hlau yuav tsum tau siv cov khoom siv high-purity aluminium, feem ntau electrolytic aluminium ua raw khoom. Thaum lub sij hawm tsim cov txheej txheem, aluminium yuav tsum tau soj ntsuam nruj thiab tshuaj xyuas kom ntseeg tau tias nws cov khoom ua tau raws li qhov yuav tsum tau ua.
Smelting: Tom qab cov txhuas raug kuaj thiab tshuaj ntsuam xyuas, nws yuav tsum tau smelted. Smelting yog ua kom sov cov txhuas kom kub thiab yaj nws mus rau hauv cov kua txhuas rau kev ua tom ntej extrusion. Thaum lub sij hawm smelting txheej txheem, nws yuav tsum tau them sai sai rau kev tswj qhov kub thiab txias lub sij hawm smelting kom paub tseeb tias cov kua txhuas zoo.
Extrusion: Cov smelted aluminium yog pub rau hauv extruder rau extrusion ua. Extrusion yog extrude cov kua txhuas rau hauv cov duab uas xav tau thiab loj los ntawm ib qho kev tuag. Thaum lub sij hawm extrusion txheej txheem, nws yog ib qhov tsim nyog los tswj lub extrusion ceev thiab extrusion siab los xyuas kom meej qhov zoo ntawm txhuas hlau.
Kev kos duab: Lub extruded aluminium hlau yuav tsum tau kos kom nws nyias. Kev kos duab yog txhawm rau ncab cov hlau txhuas los ntawm kev tuag ua kom nws txoj kab uas hla thinner. Thaum lub sij hawm kev kos duab, cov duab nrawm thiab cov duab kos yuav tsum tau tswj xyuas kom zoo ntawm cov hlau txhuas.
Kev kho deg: Tom qab cov hlau txhuas tau kos, nws yuav tsum tau kho saum npoo. Kev kho saum npoo yog ntxuav thiab kho qhov chaw ntawm cov hlau txhuas kom tshem tawm cov impurities thiab oxides, txhim kho nws qhov zoo thiab corrosion kuj.
Ntim: Tom qab kev kho saum npoo, cov hlau txhuas yuav tsum tau ntim. Kev ntim khoom yog muab cov txhuas xaim rau hauv lub thawv ntim khoom tsim nyog rau kev thauj mus los thiab khaws cia. Thaum lub sij hawm ntim cov txheej txheem, nws yog ib qho tsim nyog los tiv thaiv qhov saum npoo ntawm txhuas hlau kom tsis txhob muaj qhov puas tsuaj.
