Qhov teeb meem tseem ceeb tshaj plaws nyob rau hauv aluminium bronze phaj yog aluminium, silicon thiab magnesium. Thaum lawv muaj pes tsawg leeg tshaj 0.005 feem pua, qhov tshwm sim ntawm SiO2, MgO thiab Al2O3 hlau oxides yuav ua phem rau ib puag ncig thiab txo cov yam ntxwv ntawm qee yam ntawm aluminium alloy. .
Thaum smelting aluminium bronze phaj, vim hais tias lub melting point ntawm zinc yog kuj tsis tshua muaj thiab nws muaj zoo kab mob nrog oxygen, nws yuav tsum tau melted tom qab deamination ntawm cov tshuaj. Nws yog qhov zoo los tiv thaiv kev pheej hmoo ntawm kev tsim SnO2. Cov qauv ntawm kev deamination ntawm zinc thiab phosphorus nyob rau hauv cov kev daws teeb meem, lub converted 2ZnO thiab P2O5 yog ib qho yooj yim mus cais los ntawm cov tshuaj, thiab nws yog zoo los txhim kho lub fluidity ntawm cov tshuaj.
Kev siv cov khoom pov tseg rov qab qhuav, lossis txawm tias thawj zaug preheating ntawm tus nqi ua ntej melting, tuaj yeem txo lossis tiv thaiv cov tshuaj los ntawm kev zom thiab nqus cov vapors. Raws li kev faib ua feem ntawm cov hlau tshiab thiab cov txheej txheem pov tseg kuj tseem muaj txiaj ntsig zoo rau cov yaj zoo. Qhov kev thov rau kev ua cov khoom pov tseg feem ntau tsis haum rau ntau tshaj 20 feem pua rau 30 feem pua. Cov tshuaj uas muaj kuab paug me ntsis los ntawm qhov seem tuaj yeem yog huab cua -oxidized los ntawm tshuab cua lossis los ntawm kev ntxiv cov tshuaj txo qis (xws li tooj liab chloride CuO). Cov khib nyiab uas muaj kuab paug hnyav los ntawm qee cov khoom seem tuaj yeem ua kom zoo dua los ntawm kev siv cov kuab tshuaj organic lossis cov pa roj tsawg, suav nrog kev rov ua dua thiab lwm txoj hauv kev los txhim kho lawv qhov zoo.
Kev noj zaub mov kom zoo thiab melting ib ntus, suav nrog kev xaiv ntawm DC hlau -core induction rauv nrog pom tseeb sib xyaw thiab melting nyhuv rau smelting, muaj txiaj ntsig zoo rau kev txo qis thiab tiv thaiv cov porosity shrinkage. Ntxiv ib qho nyiaj npib tsib xee rau cov kev daws teeb meem yog qhov zoo rau kev ua kom cov coagulation thiab crystallization tus nqi ntawm cov tshuaj, thiab muaj cov txiaj ntsig zoo ntawm kev txo qis thiab tiv thaiv kom tsis txhob shrinkage. Zoo sib xws additives, zirconium thiab lithium kuj raug xaiv. Txoj kev sib xyaw ua ke ntawm melting tooj liab alloy txhuas sib cais thiab tom qab ntawd qhia cov tshuaj txhuas rau hauv cov tshuaj tooj liab ntawm 1150-1180 degree tuaj yeem siv tau. Raws li ib txwm muaj, smelting aluminium bronze daim hlau nrog phosphorus feem ntau siv cov ntaub ntawv carbonaceous xws li charcoal lossis petroleum coke los npog cov tshuaj, es tsis txhob siv cov kuab tshuaj organic. Tus neeg sawv cev npog feem ntau siv rau hauv smelting aluminium bronze daim hlau nrog zinc yuav tsum muaj cov khoom siv raw nrog carbon xws li charcoal. Thaum nruam forging, nws tsim nyog tshaj tawm tias qhov ntsuas kub yuav tsum tau tswj ntawm 100-150 degree saum toj no cov kua dej ua haujlwm zoo ntawm aluminium alloy.
