Phau Ntawv Qhia Txog Kev Tuag Casting Cov Khoom: Xaiv Cov Alloy Zoo rau Koj Qhov Haujlwm

Thaum tsim ib feem rau kev tsim khoom loj, tuag casting feem ntau yog - mus rau kev tsim khoom. Nws yog ceev, incredibly meej, thiab yields structurally ntom qhov chaw nrog zoo heev nto finishes. Txawm li cas los xij, qhov kev vam meej ntawm cov khoom siv tuag tsis yog nyob ntawm qhov tsim pwm lossis kev txhaj tshuaj siab xwb - nws pib nrog xaiv cov khoom tsim nyog.

Tsis zoo li lwm txoj kev tsim khoom uas koj tsuas yog qhia "steel" lossis "yas," tuag casting cia siab rau cov uas tsis yog-ferrous hlau alloys, txhua tus coj ntau yam sib txawv ntawm cov khoom siv, qhov hnyav, thiab cov nqi tsim khoom rau lub rooj.

Yog tias koj tab tom ntsuas cov ntaub ntawv rau koj qhov project tom ntej, ntawm no yog qhov ua tau zoo, tsis muaj - tsis muaj qhov tsis txaus ntseeg ntawm qhov tseem ceeb tuag casting alloys siv hauv kev lag luam niaj hnub no.

1. Aluminium Alloys: Kev Lag Luam Ua Haujlwm

Aluminium yog nyob deb ntawm cov khoom siv dav siv hauv niaj hnub tuag casting. Yog tias koj tuav cov khoom siv hlau sib sib zog nqus-txawm nws yog lub tsheb kis tau tus mob, lub dab dej kub rau cov khoom siv hluav taws xob, lossis cov khoom siv hluav taws xob ruaj khov- yuav muaj feem ua rau nws tuag cam khwb cia txhuas.

Lub zog tseem ceeb:Nws muaj qhov tshwj xeeb lub zog - rau - qhov hnyav piv, siab thermal thiab hluav taws xob conductivity, thiab qhov zoo ntawm qhov ntev. Nws kuj tseem khaws nws lub zog ntawm kev ua haujlwm siab kub.

Common Alloys: A380yog tus qauv tsim qauv hauv kev lag luam; nws muaj qhov zoo tshaj plaws sib npaug ntawm cov khoom siv kho tshuab thiab yooj yim ntawm casting. Rau cov khoom uas xav tau kev tiv thaiv corrosion ntau dua lossis zoo dua ductility, engineers feem ntau tig musA360los yogA413.

Kev Ua Lag Luam Ua Lag Luam - tawm:Aluminium muaj qhov siab melting point (nyob ib ncig ntawm 600℃/ 1110℃F). Qhov no yuav tsum tau "txias-chamber" tuag casting, uas muaj lub sij hawm voj voog qeeb me ntsis dua li kub-chamber txoj kev, thiab ua rau hnav thiab tsim kua muag ntawm cov hlau tuag dhau sijhawm.

2. Zinc Alloys: Kev xaiv Precision

Yog tias koj qhov tseem ceeb yog qhov tseeb qhov tseeb, cov phab ntsa nyias nyias, thiab qhov tsis zoo ntawm qhov chaw tiav ncaj qha tawm ntawm cov pwm, zinc yog qhov nyuaj los tuav.

Lub zog tseem ceeb:Zinc alloys yog incredibly yooj yim rau cam khwb cia. Vim tias zinc muaj cov ntsiab lus melting tsawg (nyob ib ncig ntawm 420℃/ 780℃F), nws tuaj yeem ua tiav siv "kub-chamber" tuag casting. Qhov no tso cai rau lub voj voog ntau lawm, thiab cov pwm hlau tuaj yeem siv tau yooj yim rau ntau tshaj li ib lab txhaj tshuaj yam tsis muaj degrading. Zinc kuj tseem ua tau zoo heev, ua rau nws zoo rau qhov chaw uas yuav tsum tau ncej-casting los ua ke xws li riveting lossis crimping.

Common Alloys:CovZamaktsev neeg (Zamak 3, Zamak 5) ua lag luam rau cov khoom siv kho kom zoo nkauj, cov khoom siv tsheb, thiab cov khoom siv hluav taws xob.ZA-8thiabZA-27yog siv thaum lub zog muaj zog dua thiab hnav tsis kam.

Kev Ua Lag Luam Ua Lag Luam - tawm:Qhov hnyav thiab kub. Zinc hnyav -kwv yees li ob thiab ib nrab zaug denser dua li txhuas. Nws kuj tseem poob lub zog tseem ceeb yog tias raug kub hnyiab ntev, yog li nws tsis haum rau hauv qab - - hood automotive daim ntaub ntawv lossis siab - huab cua puag ncig.

3. Magnesium Alloys: Qhov kawg Lub teeb yuag

Thaum qhov hnyav txuag trump yuav luag txhua yam ntxiv, magnesium yog cov khoom siv zoo tshaj plaws ntawm kev xaiv. Nws yog lub teeb pom kev zoo hlau muaj nyob hauv kev tsim khoom niaj hnub no.

Lub zog tseem ceeb:Magnesium yog kwv yees li 33% sib zog dua aluminium thiab 75% sib zog dua zinc, tab sis nws tuav lub zog zoo - rau - qhov hnyav piv. Nws kuj muab kev tiv thaiv zoo EMI / RFI (qhov tseem ceeb rau cov khoom siv hluav taws xob) thiab khav theeb zoo dua cov yam ntxwv dampening, txhais tau tias nws nqus cov kev vibrations zoo heev.

Common Alloys: TIAB SA 91Dyog tus qauv alloy rau kev lag luam feem ntau daim ntawv thov, muab cov khoom sib xyaw ntawm lub zog thiab corrosion kuj.AM 60Btau txais kev pom zoo rau cov khoom siv kev nyab xeeb tsheb (xws li lub kauj log cores lossis cov qauv khiav ceev) vim nws cov ductility ntau dua thiab cuam tshuam tsis kam.

Kev Ua Lag Luam Ua Lag Luam - tawm:Nqi thiab tuav kev ruaj ntseg. Raw magnesium yog kim dua li txhuas. Tsis tas li ntawd, molten magnesium reacts hnyav nrog oxygen, yuav tsum tau tshwj xeeb kev teeb tsa roj hauv qhov chaw tsim khoom los tiv thaiv hluav taws, uas ua rau cov nqi tsim khoom.

4. Copper Alloys (Brass): Lub Hnyav - Lwm Txoj Haujlwm

Copper-raws li alloys xws li tooj dag thiab tooj liab tsis tshua muaj nyob rau hauv tuag casting vim tus nqi, tab sis lawv yog irreplaceable thaum xav tau kev ua tau zoo heev.

Lub zog tseem ceeb:Unrivaled corrosion kuj, siab hluav taws xob conductivity, thiab zoo kawg hnav tsis kam. Cov khoom siv tooj dag yog lub hauv paus muaj zog, spark- tiv taus, thiab muaj cov tshuaj tua kab mob ntuj.

Kev Ua Lag Luam Ua Lag Luam - tawm:Tus nqi thiab cov cuab yeej hnav. Copper alloys muaj qhov siab tshaj plaws melting point (feem ntau tshaj 900℃/ 1650℃F). Kev quab yuam hlau no kub rau hauv cov pwm hlau ua rau muaj kev kub ntxhov hnyav heev. Yog li ntawd, cov hlau kim kim tuag degrade sai, ua rau tooj dag tuag casting kev lag luam tsuas yog siv rau cov kev siv tseem ceeb xws li hnyav-cov kav dej li qub, cov khoom siv hluav taws xob, thiab cov khoom siv hauv hiav txwv.

Yuav Xaiv Li Cas: Daim Ntawv Qhia Ceev

Thaum txiav txim siab txog cov khoom siv tuag casting, zam dhau - engineering. Nug koj tus kheej seb qhov haujlwm tseem ceeb yog dab tsi:

Los ntawm kev sib piv koj qhov kev cuam tshuam ib puag ncig, kev ntxhov siab, thiab nyiaj txiag lub hom phiaj rau cov yam ntxwv ntawm cov alloys, koj tuaj yeem ua kom muaj txiaj ntsig zoo tshaj plaws thaum ua kom ntseeg tau tias muaj kev ntseeg siab, ntev ntev - cov khoom tiav.
