Piav qhia meej txog txoj kev casting ntawm aluminium pas nrig kauj ruam rau koj

1. Xaiv qhov raug casting kub
Qhov tseeb casting kub kuj yog ib qho tseem ceeb los tsim cov khoom zooaluminium bars. Lub forging defects xws li coarse grain thiab feather crystal yog ib qho yooj yim tshwm sim thaum kub siab.
Tom qab cov nplej ua kom zoo, qhov ntsuas kub ntawm cov kua 6063 aluminium alloy tuaj yeem tsim nyog nce, feem ntau ntawm 720-740 ℃, vim:
(1) Cov kua txhuas ua kua nplaum tom qab cov nplej ua kom zoo thiab yooj yim solidification crystallization. (2) Muaj cov kua-khoom ob-theem ntau dhau cheeb tsam hauv crystallization pem hauv ntej ntawm aluminium bar hauv forging. Qhov siab dua forging kub muaj qhov nqaim ntau dhau, uas yog qhov zoo rau kev khiav tawm ntawm cov roj uas tsis suav nrog cov crystallization pem hauv ntej. Tau kawg, qhov kub tsis tuaj yeem siab dhau, qhov kub siab forging ntau dhau yuav txo lub sijhawm siv tau zoo ntawm cov nplej refiner thiab ua rau cov nplej loj heev.
2. Thaum muaj tej yam kev mob, tag nrho preheat, qhuav lub casting system xws li ntws tank thiab shunt phaj los tiv thaiv cov tshuaj tiv thaiv ntawm dej thiab kua txhuas los ua hydrogen nqus.
3. Nyob rau hauv aluminium bar forging, sim tiv thaiv cov turbulence thiab dov ntawm cov kua txhuas, tsis txhob tsuas yog siv cov cuab yeej los do cov kua txhuas nyob rau hauv lub ndlwg tank thiab shunt phaj, thiaj li hais tias cov kua txhuas nyob rau hauv lub nto ntawm oxide zaj duab xis nyob rau hauv kev tiv thaiv ntawm ruaj khov ntws mus rau hauv lub crystallizer crystallization.
Qhov no yog vim hais tias cov khoom agitation kua txhuas thiab cov kua ntws dov yuav ua rau tag nrho cov nto ntawm aluminium oxide zaj duab xis phua, tsim ib tug tshiab oxidation, tib lub sij hawm, cov oxide zaj duab xis koom nyob rau hauv kua txhuas.
Kev tshawb fawb qhia tau hais tias oxide zaj duab xis muaj zog adsorption muaj zog, nws muaj 2% dej, thaum cov oxide zaj duab xis koom nrog cov kua txhuas, cov dej hauv oxide zaj duab xis thiab kua txhuas cov tshuaj tiv thaiv, tsim hydrogen nqus thiab slag.
4. Aluminium bar aluminium kua filtration, pom yog ib txoj hauv kev zoo kom tshem tawm cov nonmetal slag nyob rau hauv cov kua txhuas, nyob rau hauv forging ntawm 6063 aluminium alloy, feem ntau nrog ntau txheej iav fiber ntau pom los yog ceramic lim phaj pom, tsis muaj teeb meem dab tsi ntawm filtration txoj kev siv.
Txhawm rau kom ntseeg tau qhov kev pom zoo ntawm cov kua txhuas, cov kua txhuas yuav tsum tau muab tshem tawm ntawm qhov chaw ua ntej pom, vim tias cov nplais nplaum yog ib qho yooj yim rau jam lub lim mesh ntawm cov khoom siv raw, thiaj li tsis tuaj yeem ua kom pom tau ib txwm, txoj hauv kev yooj yim kom tshem tawm cov nplais ntawm cov kua txhuas yog los teeb tsa lub phaj slag hauv lub tank ntws, yog li cov kua txhuas tau muab tshem tawm los ntawm cov kua nplaum ua ntej filtration.
