Kev txheeb xyuas cov txheej txheem tsim khoom ntawm cov khoom siv txhuas rau cov khoom siv hauv tsev

Lub hauv paus zoo ntawm cov ntaub ntawv txhuas rau cov khoom vaj khoom tsev yog qhov tob tob hauv cov txheej txheem tsim khoom nruj thiab tsim qauv. Los ntawm cov ntaub ntawv raw mus rau cov ntaub ntawv tiav, kev tswj xyuas kev tshawb fawb thiab thev naus laus zis ntawm txhua theem sib koom ua ke txiav txim siab lawv lub zog ntawm cov qauv, qhov tseeb qhov tseeb, thiab qhov zoo ntawm qhov chaw, yog li txhawb nqa cov qauv siab ntawm kev ua haujlwm thiab kev zoo nkauj hauv cov khoom siv hauv tsev.

Cov txheej txheem pib nrog kev xaiv thiab smelting ntawm siab - zoo aluminium ingots. Raws li cov yam ntxwv ntawm cov hlau uas xav tau rau cov khoom vaj khoom tsev, aluminium ingots nrog cov purity haum thiab cov kab sib piv tau raug xaiv. Cov ingots no yog rhuab nyob rau hauv ib lub qhov cub rau qhov kub thiab txias, impurities raug tshem tawm, thiab cov muaj pes tsawg leeg yog kho kom zoo ib yam thiab ruaj khov yaj. Kev tswj kub thiab degassing / slag tshem tawm cov txheej txheem ntawm theem no ncaj qha cuam tshuam rau qhov ntom thiab cov khoom siv kho tshuab ntawm cov ntawv txuas ntxiv, ua thawj kab ntawm kev tiv thaiv kev puas tsuaj sab hauv.

Tom qab ntawd los casting thiab homogenization. Molten aluminium yog cam khwb cia rau hauv billets los ntawm kev nruam lossis ib nrab- nruam casting. Cov txheej txheem no yuav tsum muaj kev tswj xyuas meej ntawm qhov txias txias thiab crystallization tej yam kev mob kom tau txais cov qauv zoo li qub thiab zoo. Tom ntej no homogenization annealing tshem tawm cov kev ntxhov siab sab hauv, txhim kho kev faib tawm ntawm cov ntsiab lus alloying, thiab muab lub hauv paus nrog cov microstructure zoo ib yam thiab cov khoom rau cov txheej txheem extrusion tom ntej.

Cov txheej txheem tseem ceeb yog profile extrusion. Ib daim ntawv rhuab mus rau lub xeev yas yog muab tso rau hauv lub extruder thiab extruded los ntawm ib tug tshwj xeeb tuag los tsim ib tug predetermined ntoo khaub lig-sectional shape. Kev tsim thiab kev tsim khoom precision ntawm qhov tuag txiav txim siab qhov ntev ntev thiab contour clarity ntawm qhov profile, thaum qhov sib txuam ntawm kev ceev, kub, thiab siab thaum lub sij hawm tsim cov txheej txheem cuam tshuam rau uniformity ntawm cov hlau ntws, tsis txhob muaj qhov tsis xws luag xws li twisting thiab wavy kab. Cov kauj ruam no yog qhov tseem ceeb rau kev ua tiav cov qauv sib txawv thiab cov kab zoo nkauj hauv tsev aluminium profiles.

Cov extruded profiles undergo online quenching thiab kev laus kho kom xauv rau hauv qhov yuav tsum tau muaj zog thiab hardness. Tom qab ntawd lawv nkag mus rau hauv cov txheej txheem txiav thiab ua kom ncaj, siv qhov loj me thiab ntau - cov khoom siv rau cov menyuam ncaj los kho qhov khoov thiab sib tw, kom ntseeg tau tias qhov ncaj thiab qhov sib npaug ua tau raws li qhov xav tau nruj ntawm kev sib dhos hauv tsev.

Kev kho deg yog ib kauj ruam tseem ceeb hauv kev txhim kho kev ntxhib los mos thiab kav ntev. Cov txheej txheem muaj xws li anodizing, electrophoretic txheej, thiab electrostatic hmoov txheej, uas yuav tsum tau xaiv raws li huab cua tsis kam, hnav tsis kam, thiab cov kev xav kom zoo nkauj ntawm cov ntawv thov hauv tsev scenario. Cov txheej txheem kev kho mob yuav tsum muaj kev tswj xyuas nruj ntawm pretreatment cleanliness, zaj duab xis thickness, thiab curing tej yam kev mob los xyuas kom meej cov xim sib xws, muaj zog adhesion, thiab ib puag ncig ua raws.

Kev ntsuam xyuas online thiab kev ua piv txwv yog ua nyob rau hauv tag nrho cov txheej txheem, suav nrog qhov tseeb qhov tseeb, cov khoom siv kho tshuab, thiab qhov zoo ntawm qhov chaw, kom ntseeg tau tias txhua pawg ntawm txhuas ua tau raws li cov qauv kev ntseeg siab rau cov khoom vaj khoom tsev. Cov txheej txheem kev sib cuam tshuam no txuas qhov sib txawv ntawm cov khoom siv raw thiab cov khoom tiav hauv kev tsim cov khoom vaj khoom tsev aluminium, muab cov khoom lav rau kev hloov kho kom zoo hauv kev lag luam.
