Dab tsi yog qhov txawv ntawm Casting thiab Forging?

Thaum nws los txog rau metalworking thiab manufacturing,castingthiabforgingyog ob lub hauv paus txheej txheem siv los tsim cov hlau rau hauv cov khoom siv ua haujlwm. Ob txoj kev muaj lawv qhov zoo thiab qhov tsis zoo thiab haum rau kev siv sib txawv, ib puag ncig, thiab kev cia siab rau kev ua haujlwm.

To taub covqhov sib txawv ntawm casting thiab forgingNws yog ib qho tseem ceeb rau engineers, procurement professionals, thiab project managers tab tom nrhiav xaiv txoj kev tsim khoom tsim nyog rau lawv qhov chaw. Kab lus no rhuav tshem qhov sib txawv tseem ceeb ntawm kev casting thiab forging raws li cov txheej txheem, cov khoom siv, tus nqi, lub zog, thiab lwm yam.

Casting yog dab tsi?

Castingyog txheej txheem uas hlau yog melted rau hauv ib lub kua, ncuav rau hauv pwm, thiab tso cai rau solidify rau hauv ib tug tshwj xeeb zoo. Tom qab txias, cov pwm raug tshem tawm, thiab cov khoom kawg tuaj yeem ua tiav ntxiv lossis machining.

Muaj ntau ntau hom txheej txheem casting, suav nrog:

• Xuab zeb casting

• Investment casting (poob-wax)

• Tuag casting

• Centrifugal casting

Casting yog qhov zoo tagnrho rau kev tsim khoomcomplex geometrythiabqhov ntauntawm cov khoom nrogtsawg machining.

Forging yog dab tsi?

Forgingyog cov txheej txheem tsim khoom uas koom nrogshaping hlau siv compressive zog, feem ntau nrog rauj lossis nias. Cov hlau feem ntau yogheated tab sis tseem khov, thiab deformation yog siv los ua kom tiav daim ntawv xav tau.

Hom forging muaj xws li:

• Qhib-tuag forging

• Kaw-tuag forging

• Txias forging

• Kub forging

• Ntiv nplhaib

Forging txhim kho covmechanical zogthiabstructural kev ncaj nceesntawm hlau Cheebtsam los ntawm aligning cov nplej ntws nyob rau hauv cov kev taw qhia ntawm kev nyuaj siab.

Qhov sib txawv tseem ceeb ntawm Casting thiab Forging

1. Txheej txheem txheej txheem

• Casting: Koom nrogmelting cov hlauthiab ncuav nws mus rau hauv pwm. Cov khoom siv solidifies rau hauv cov duab uas xav tau.

• Forging: Koom nrogdeforming khoom hlausiv mechanical quab yuam kom ua tiav cov duab.

Cov ntsiab lus: Casting yog ua kua-rau-khoom hloov, thaum forging yog solid-state deformation.

2. Khoom Khoom

• Casting: Feem ntau suav nrogporosity, shrinkage, thiabgrain discontinuitiesvim kev ua kom txias.

• Forging: Muajrefined grain qauv, ntau toughness, thiabsiab zog tsis kam.

Cov ntsiab lus: Forged qhov chaw muaj zog thiab txhim khu kev qha, tshwj xeeb tshaj yog nyob rau hauv kev cuam tshuam los yog kev ntxhov siab.

3. Mechanical Strength

• Casting: Nruab nrab mus rau siab zog, tab sis tuaj yeem nkig thiab ua rau cov kab nrib pleb lossis qhov tsis xws luag.

• Forging: Superior zog vim grain flow alignment thiab densification ntawm cov hlau.

Cov ntsiab lus: Forging tsim cov khoom siv nrogkev cuam tshuam ntau dua thiab qaug zogtshaj casting.

4. Nto Finish thiab Tolerances

• Casting: tuaj yeem ua tiav cov npoo du thiab cov duab zoo sib xws nrog cov machining tsawg.

• Forging: Feem ntau yuav tsum tau ua kom tiav thiab machining ntau dua, tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem qhib-tuag.

Cov ntsiab lus: Casting muaj qhov zoo dua pib ua tiav; forging tej zaum yuav xav tau kev ua haujlwm thib ob.

5. Tsim Complexity

• Casting: Zoo tagnrho raucomplex duabthiabnyias phab ntsauas yuav nyuaj rau forge.

• Forging: Zoo dua haum rauyooj yim dua, symmetricalcov duab vim muaj kev txwv cov cuab yeej.

Cov ntsiab lus: Casting txhawb cov txheej txheem nyuaj thiab hollow; forging yog txwv los ntawm tuag tsim.

6. Qhov loj thiab qhov hnyav ntawm Cheebtsam

• Casting: Yooj yim tsimcov khoom loj thiab hnyav(piv txwv li, lub cev valve, lub twj tso kua mis).

• Forging: Feem ntau siv raume me mus rau nruab nrab qhov chaw, txawm tias loj-scale forgings tau.

Cov ntsiab lus: Casting yog nyiam rau qhov loj heev uas tsis tshua muaj neeg xav tau.

7. Lub Sijhawm Lead thiab Ntau Lawm Ceev

• Casting: Feem ntau nrawm dua rau cov ntim siab thaum pwm tau npaj.

• Forging: Kev qeeb qeeb vim cov cuab yeej teeb tsa thiab cov cua sov xav tau, tab sis zoo dua haum rau kev tsim khoom me me rau nruab nrab.

Cov ntsiab lus: Casting yog ntau npaum rauntau lawm; forging muaj luv luv khiav nrog siab zog.

8. Tus nqi sib piv

• Casting: Tus nqi pib qis dua, tshwj xeeb tshaj yog rau qhov nyuaj.

• Forging: Cov cuab yeej siv siab dua thiab cov nqi hluav taws xob, tab sisqis dua tus nqithiabkev ua tau zoo duadhau sijhawm.

Cov ntsiab lus: Casting yog pheej yig dua pem hauv ntej; forging muabtus nqi mus sij hawm ntevhauv kev ua haujlwm siab.
