Q1: Alumina muab rho tawm li cas los ntawm Bauxite Ore?
Bauxite yog crushed thiab tov nrog kub sodium hydroxide nyob rau hauv tus txheej txheem bayer. Qhov no yaj aluminium hydroxide thaum tawm hauv impurities li "cov av nkos liab" seem. Cov kev daws teeb meem yog txias rau nag lossis cov muaju ntshiab alumina. Cov muaju no muaj qab zib yog li muab rov qab ntawm 1000℃kom tshem tawm cov lwg roj. Txog 2-3 tons ntawm bauxite tau 1 tuj ntawm alumina, nrog cov txheej txheem siv lub zog tseem ceeb.
Q2: Yuav ua li cas thaum lub sij hawm txhuas smelting?
Alumina Dissolves hauv Molten Cryolite ntawm 950℃hauv electrolytic cells. Cov carbon anodes tau noj, ua kom haum thaum lub sijhawm txo tus txheej txheem txo qis. Hluav taws xob tam sim no (4 {- 6v, 100-300ka) cais txhuas los ntawm oxygen ions. Molten Aluminium sau ntawm lub xov tooj ntawm tes thiab yog siphoned ib ntu. Txoj kev ua haujlwm no-héreult noj txog 13-15 kwh ib kg ntawm txhuas tsim.
Q3: Yuav ua li cas cov khoom noj tau hloov mus rau semi-} Cov khoom tiav tiav?
DC Casting tsim cov kev cuam tshuam loj rau yob lossis extrusion. Homogenization Cua Sov (500-600 Degree) tshem tawm kev cais tawm hauv cov qauv kev txhim kho. Kub Rolling txo cov tuab ntawm 60cm txog 2-6mm los ntawm ntau tus dhau mus. Txias dov ntxiv ntxiv txo cov tuab nrog cov kev tiv thaiv kev tiv thaiv (± 1%). Intermediate annealing restores duction ntawm cov theem ua haujlwm txias.
Q4: Cov hom kev sib txawv li cas rau cov duab txhuas cov khoom siv?
Extrusion Fores ua kom kub alumined aluminium billts los ntawm tuag los tsim profiles. Forging siv compressive rog rau dlhos cov qauv qauv rau lub zog. Tuag casting injections molten aluminium nyob rau hauv siab rau hauv steel pwm. Daim ntawv hlau txoj kev suav nrog kev sib sib zog nqus rau cov kaus poom lossis stamping rau nws pib panels. Adillitive kev tsim khoom tam sim no tso cai rau cov 3D luam tawm txhuas qhov chaw nrog cov cim las laser melting.
Q5: Yuav ua li cas kho cov chaw txhim kho txhuas ua haujlwm?
Anodizing tsim cov roj oxide (5-25μm) rau corrosion / hnav tsis kam. Hmoov txheej muab cov xim ruaj khov, xim ua tiav ua tiav rau cov ntawv thov archectural. Cov tshuaj lom neeg hloov koob txheej txheem txheej txheem npaj cov chaw rau kev pleev xim lossis nplaum sib txuas. Neeg kho tshuab xov suav nrog txhuam hniav rau cov chaw dai kom zoo nkauj los yog muab pov rau cov rog rau cov neeg qaug zog. Electroplating tuaj yeem tso nyiaj tooj liab lossis npib tsib xee rau cov neeg muaj hluav taws xob tshwj xeeb.
