| Yam khoom | Forging | Casting |
| Txheej txheem | Forging yog txheej txheem uas siv lub tshuab forging los ua kom cov hlau dawb paug tsim cov yas deformation, txhawm rau kom tau txais qee yam khoom siv, cov duab thiab qhov loj me.Los ntawm forging tuaj yeem tshem tawm cov hlau ascast xoob tsis xws luag hauv cov txheej txheem smelting, optimize microstructure, ua kom tiav cov hlau ntws, yog li cov neeg kho tshuab cov khoom ntawm forging feem ntau zoo dua li casting ntawm tib materail.Feem ntau ntawm cov tshuab tseem ceeb whcih yuav tsum muaj kev thauj khoom siab thiab kev ua haujlwm hnyav siv qhov chaw forging. | Casting yog txheej txheem uas muab cov kua hlau tso rau hauv cov kab noj hniav casting, tom qab txias thiab solidification kom tau txais qhov yuav tsum tau ua. |
| Khoom siv | Forging cov khoom siv dav siv puag ncig steel, square steel.muaj cov pa roj carbon steel, alloy steel, stainless hlau nrog rau qee cov hlau tsis-ferrous uas yog siv rau hauv areospace thiab precision kev lag luam. | Casting feem ntau txais yuav grey cam khwb cia hlau, dectile cam khwb cia hlau, malleable cam khwb cia hlau, thiab "cam khwb cia hlau. Common casting non-ferrous hlau: tooj dag, tin bronze, wuxi bronze, aluminium alloy thiab lwm yam. | Raws li qhov sib npaug, forgingmetal muaj kev ua tau zoo dua hauv cov khoom siv kho tshuab, thaum casting yog superior hauv molding. |
| Kev tshwm sim | Oxidation cov tshuaj tiv thaiv ntawm forging steel thaum lub sij hawm kub txheej txheem yuav ua rau me ntsis kylin grain nyob rau hauv qhov chaw ntawm forged thoob hniav.Tsis tas li ntawd, raws li forging yog tsim los ntawm molding, tom qab tshem tawm qhov nyiaj pub dawb nyob rau hauv pwm, yuav muaj ib txoj kab sib faib hauv cov hniav forged thoob. | Muaj cov xuab zeb kab thiab casting kiting nyob rau saum npoo ntawm casting thoob hniav. |
| Mechanical Property | Forging txheej txheem tuaj yeem lav qhov txuas ntxiv ntawm cov hlau fiber ntau, thiab ua kom tiav cov hlau ntws, lav cov khoom siv zoo thiab lub neej ua haujlwm ntev ntawm lub thoob cov hniav, uas txheej txheem casting yog qhov sib piv. | Piv nrog rau qhov chaw casting, hlau cov qauv thiab cov khoom siv kho tshuab tuaj yeem txhim kho tom qab forging.Lub koom haum casting tom qab forging thermal deformation, tus thawj bulky siv lead ua thiab columnar grain hloov mus rau hauv nplua nplej, thiab uniform isometric recystallization lub koom haum, cia tus qauv ntawm thawj segregation nyob rau hauv ingot, osteoporosis, porosity slag inclusion thiab lwm yam compact kom zoo dua, yog li txhim kho. hlau plasticity thiab mechanical zog.
Forging yog kom tau txais cov duab uas xav tau los ntawm nias cov hlau los ntawm cov yas deformation, feem ntau yog siv rauj lossis siab.Forging txheej txheem muaj cov qauv zoo granular, thiab txhim kho cov hlau lub cev muaj zog, hauv kev siv tswv yim, tsim kom zoo tuaj yeem lav cov nplej ntws hauv cov kev taw qhia ntawm kev ntxhov siab loj.Thaum casting yog kom tau cov hlau tsim cov khoom los ntawm txhua yam ntawm cov txheej txheem casting, uas yog muab cov hlau ua kua rau hauv cov pwm npaj kom tau txais cov duab, qhov loj thiab cov khoom, los ntawm smelting, casting, txhaj tshuaj lossis lwm txoj kev casting, thiab shakeout tom qab. txias, ntxuav thiab zaum kawg-kev kho mob. |
