Txheej txheem cej luam ntawm Aluminium Ingot Casting txheej txheem

I. Kev Taw Qhia

Qhov zoo ntawm thawj txhuas ua nyob rau hauv txhuas electrolytic hlwb txawv heev, thiab nws muaj ntau yam hlau impurities, gases, thiab cov khoom uas tsis yog-hlau inclusions. Lub luag haujlwm ntawm aluminium ingot casting yog txhawm rau txhim kho kev siv cov qib qis aluminium kua thiab tshem tawm impurities ntau li ntau tau.

II. Classification ntawm Aluminium Ingots

Aluminium ingots tau muab faib ua peb hom raws li muaj pes tsawg leeg: remelting ingots, high-purity aluminium ingots, thiab aluminium alloy ingots. Lawv tuaj yeem raug cais los ntawm cov duab thiab qhov loj me, xws li slab ingots, round ingots, phaj ingots, thiab T-shaped ingots. Hauv qab no yog ob peb hom ntawm aluminium ingots:

Remelting ingots: 15kg, 20kg (≤99.80% Al)

T-shaped ingots: 500kg, 1000kg (≤99.80% Al)

High-purity aluminium ingots: 10kg, 15kg (99.90% ~ 99.999% Al)

Aluminium alloy ingots: 10kg, 15kg (Al-Si, Al-Cu, Al-Mg)

Phaj ingots: 500 ~ 1000kg (rau phaj ntau lawm)

Round ingots: 30 ~ 60kg (rau hlau kos duab)

IV. Txheej txheem Casting

Cov txheej txheem txhuas ingot casting tam sim no feem ntau siv cov txheej txheem pouring, qhov twg txhuas cov kua yog poured ncaj qha rau hauv pwm thiab tso cai rau txias ua ntej extraction. Qhov zoo ntawm cov khoom yog txiav txim siab nyob rau hauv cov kauj ruam no, thiab tag nrho cov txheej txheem casting revolves nyob rau theem no. Casting yog cov txheej txheem ntawm lub cev ntawm cov kua aluminium txias thiab crystallizing nws mus rau hauv cov khoom txhuas ingots.

1. Nruam Casting

Nruam casting muaj ob txoj hauv kev: sib xyaw rauv casting thiab sab nraud casting, ob qho tib si siv cov tshuab nrum nruam. Mixed furnace casting suav nrog nchuav cov kua txhuas rau hauv lub qhov cub sib xyaw rau casting thiab feem ntau yog siv los ua cov remelting ingots thiab alloy ingots. Sab nrauv casting ncaj qha nchuav los ntawm lub crucible mus rau lub tshuab casting thiab siv thaum cov khoom siv casting tsis tuaj yeem ua tau raws li cov kev xav tau ntau lawm lossis thaum cov khoom xa tuaj tsis zoo.

2. Vertical Semi-Nruam Casting

Vertical semi-nruam casting feem ntau yog siv los ua txhuas hlau ingots, phaj ingots, thiab ntau yam deformation alloys rau kev ua. Tom qab cov khoom sib tov, cov kua txhuas yog nchuav rau hauv lub qhov cub sib xyaw. Rau cov hlau ingots, ib qho tshwj xeeb Al-B disc ntxiv kom tshem tawm titanium thiab vanadium los ntawm cov kua txhuas ua ntej casting. Qhov zoo ntawm txhuas hlau ingots yuav tsum du yam tsis muaj slag, tawg, los yog roj pores. Cov kab nrib pleb yuav tsum tsis pub ntev tshaj 1.5 hli, slag thiab ntug wrinkles yuav tsum tsis txhob ntau tshaj 2 hli nyob rau hauv qhov tob, thiab lub cross-section yuav tsum tsis txhob muaj cov kab nrib pleb, roj pores, thiab tsis pub tshaj 5 slag inclusions me tshaj 1 hli.Rau phaj ingots, Al-Ti-B alloy (Ti5% B1%) yog ntxiv rau kev ua kom zoo. Tom qab ntawd cov ingots yog txias, tshem tawm, sawn mus rau qhov yuav tsum tau qhov ntev, thiab npaj rau lub voj voog casting tom ntej.
