Taw qhia Koj puas tuaj yeem paub qhov txawv ntawm aluminium, thawj txhuas, electrolytic aluminium, aluminium ingot thiab alumina?
Luv luv qhia txog aluminium, thawj aluminium, electrolytic aluminium, aluminium ingot, aluminium oxide thiab qhov sib txawv ntawm lawv. Yog tias koj txaus siab, thov nyeem!
Electrolytic aluminium yog ib txoj kev ntawm smelting metallic aluminium. Feem ntau, alumina yog decomposed rau hauv metallic aluminium los ntawm high tam sim no nyob rau hauv ib tug electrolytic cell.
Aluminium ingots muab faib ua high-purity aluminium ingots, aluminium alloy ingots thiab aluminium ingots remelted raws li lawv muaj pes tsawg leeg. Raws li nws cov duab thiab qhov loj me, nws tuaj yeem muab faib ua round ingots, slab ingots, bar ingots, T-shaped ingots thiab lwm yam.
Aluminium yog cov hlau dawb-dawb, nyob rau qib thib peb tom qab cov pa oxygen thiab silicon nyob rau hauv lub ntiaj teb crust. Aluminium yog hu ua lub teeb hlau vim nws qhov ntom ntom. Aluminium yog cov hlau tsis-ferrous nrog cov zis siab thiab siv dav, thib ob tsuas yog cov hlau hauv ntiaj teb. Qhov ntom ntawm aluminium yog li 1/3 ntawm cov hlau thiab tooj liab. Vim tias txhuas yog ua los ntawm cov khoom siv hnyav, nws feem ntau siv hauv kev tsim khoom, tsheb ciav hlau, tsheb ciav hlau, tsheb ciav hlau, tsheb, dav hlau, nkoj, foob pob hluav taws, thiab lwm yam av, hiav txwv thiab huab cua tsheb thauj mus los kom txo tau tus kheej qhov hnyav thiab ua kom muaj peev xwm thauj khoom. Ib yam li ntawd, txhuas kuj ua lub luag haujlwm tseem ceeb hauv cov khoom siv tub rog.
Alumina, tseem hu ua alumina, yog hmoov dawb. Thawj aluminium yog kua txhuas muab rho tawm thaum lub sij hawm electrolysis thiab tsis tau raug kev kho los nag. Nyob rau hauv cov cam khwb cia txhuas ingot qauv, thawj txhuas tuaj yeem hloov mus rau hauv aluminium ingot los ntawm kev kho cua txias. Yog li ntawd, alumina yog cov khoom siv raw ntawm molten aluminium, electrolytic aluminium yog cov txheej txheem, thawj aluminium yog molten aluminium nyob rau hauv cov txheej txheem electrolysis, thiab aluminium ingots yog txhuas cov khoom uas thaum kawg tuaj yeem muag hauv khw.
Electrolytic aluminium yog txhuas tau los ntawm electrolysis. Kev lag luam niaj hnub electrolytic aluminium siv cryolite-alumina molten ntsev electrolysis. Molten cryolite yog cov kuab tshuaj, alumina yog cov kuab, carbon lub cev yog anode, thiab molten aluminium yog cathode. Tom qab siv lub zog ncaj qha tam sim no, ob tug ncej hauv lub xovtooj ntawm electrolytic tau txais cov tshuaj tiv thaiv electrochemical ntawm 950 ~ 970 rau electrolysis.
Kev lag luam txhuas ingot: Cov khoom siv raw hauv peb cov kev lag luam niaj hnub hu ua aluminium ingot raws li lub teb chaws tus qauv (GB / T 1196-2008), tab sis txhua tus siv los hu nws "rau remelting". Nws yog tsim los ntawm electrolysis ntawm alumina-cryolite. Tom qab aluminium ingots nkag rau hauv kev lag luam, muaj ob hom: cam khwb cia txhuas alloys thiab deformed aluminium alloys. Casting aluminium thiab aluminium alloys yog castings tsim los ntawm txoj kev casting.
Deformed aluminium thiab aluminium alloys yog txhuas ua cov khoom tsim los ntawm kev ua haujlwm siab: daim hlau, strips, foils, raj, rods, pwm, xov hlau, thiab forgings. Raws li lub teb chaws tus qauv, "remelting siv" muab faib ua 8 qib raws li tshuaj muaj pes tsawg leeg, namely aluminium 99.90, aluminium 99.85, aluminium 99.70, aluminium 99.60, aluminium 99.50, aluminium 99.00, aluminium 99.7E, aluminium 99.6E "(Ceeb Toom: 0. 99.7% ntshiab aluminium. Nws yog hu ua "standard aluminium" hauv khw London. Raws li peb txhua tus paub, Tuam Tshoj cov txheej txheem kev tsim tawm los ntawm yav dhau los Soviet Union hauv xyoo 1950. "A00" yog Lavxias teb sab hom nyob rau hauv Soviet lub teb chaws tus qauv, "A" yog tsab ntawv Lavxias, tsis yog lus Askiv "A", los yog Suav pinyin "A". Yog hais tias nws ua tau raws li lub thoob ntiaj teb cov qauv, nws yog hu ua "standard txhuas". boiling point ntawm 2980. Nws yog ib tug ionic siv lead ua uas yuav ionized nyob rau hauv high kub Nws yog feem ntau yog siv los ua refractory cov ntaub ntawv muaj alumina yog ua los ntawm bauxite (Al2O 33H2O) thiab diaspore rau alumina nrog siab purity yuav tsum tau, feem ntau yog npaj los ntawm cov tshuaj.
