Kev cai ductile hlau xuab zeb casting qhov chaw yog ua los ntawm cam khwb cia hlau los ntawmxuab zeb casting txheej txheem. Pebxuab zeb casting Cheebtsamtau pab ntau yam kev lag luam ntawm kev xav tau siab xws li roj & roj, tsheb ciav hlau thiab tsheb ciav hlau. Peb caw peb cov neeg siv khoom los koom nrog kev tsim thiab kev tsim cov cuab yeej thiab petterns thaum pib thawj zaug. Peb cov kws tshaj lij engineers nplua nuj tuaj yeem pab txhawb koj los ntawm thawj lub tswv yim rau serial ntau lawm nrog muaj cov kws paub txog kev tsim khoom tiag tiag thiab cov khoom siv tshuaj ntsuam xyuas nrog rau cov tshuaj muaj pes tsawg leeg thiab cov khoom siv tshuab. Peb pab neeg ua haujlwm engineering yuav hloov ib qho kev txhim kho mus rau ib qho kev tsim tawm thiab tsim khoom tsim tau zoo nyob rau hauv peb cov txheej txheem tag nrho cov saw hlau.
Cam khwb cia hlau yog cov hlau-carbon cam khwb cia hlau nrog lwm cov khoom uas yog tsim los ntawm remelting npua hlau, seem, thiab lwm yam ntxiv. Rau kev sib txawv ntawm cov hlau thiab cam khwb cia hlau, cam khwb cia hlau yog txhais raws li cam khwb cia hlau nrog cov ntsiab lus carbon (min 2.03%) uas ua kom cov solidification ntawm theem kawg nrog kev hloov pauv eutectic. Raws li kev txheeb xyuas tshuaj, cam khwb cia hlau tuaj yeem yog non-alloyed lossis alloyed. Qhov ntau ntawm cov hlau alloyed yog dav dua, thiab lawv muaj ntau dua ntawm cov khoom sib xws, xws li silicon thiab manganese, lossis tshwj xeeb ntxiv, xws li npib tsib xee, chromium, aluminium, molybdenum, tungsten, tooj liab, vana-dium, titanium, ntxiv rau. lwm tus. Feem ntau hais lus, cam khwb cia hlau tuaj yeem muab faib ua grey hlau, ducitle hlau (nodular hlau), dawb cam khwb cia hlau, compacted graphite hlau thiab malleable cam khwb cia hlau.
▶ Tsim thiab tsim cov xuab zeb Casting Toolings thiab cov qauv
Ntawm peb cov qauv thiab cov cuab yeej khw, peb cov kws tsim qauv thiab cov kws tshaj lij tuaj yeem siv 2D kos duab thiab 3D qauv rau kev tsim cov cuab yeej / qauv. Yog tias ua tau, txoj kev ua ib txwm ua los kuj suav nrog. Peb cov kws tshaj lij tuaj yeem pab txhawb koj hauv kev ua 3D qauv raws li koj lub tswv yim ntxhib lossis 2D kos duab, yog tias koj xav tau.
Thaum peb tsim cov cuab yeej / patters thiab cov txheej txheem ntau lawm ntawm covxuab zeb casting qhov chaw, peb ib txwm xav txog qhov tseem ceeb hauv qab no:
• Txo qhov hnyav kom txo koj cov nqi.
• Qhov tseeb qhov ntev kom txo lossis tsis xav tau kev siv tshuab.
• Yooj yim rau nruab nrog lwm yam khoom.
• Cov ntaub ntawv tsim nyog kom ua tau raws li cov kev xav tau ntawm cov khoom siv kho tshuab tab sis tswj tag nrho cov nqi.
• Ua tau zoo rau kev tsim khoom loj.
• Ib puag ncig-phooj ywg.
▶ Metallurgy, Chemical Composition thiab Mechanical Properties of the Material
Lub foundry ntawm RMC yog txawm peem rau nrog ib tug ua tiav metallurgical kuaj los txiav txim cov tshuaj thiab mechanical yam ntxwv ntawm txhua yaj thiab soj ntsuam cov metallurgic mob ntawm cov hlau molten ua ntej pouring. Microsections raug tshuaj xyuas nyob rau hauv lub microscope kom tau txais cov ntaub ntawv zaum kawg. Yog tias ua tau lossis xav tau, peb tuaj yeem muab 3.1 Daim Ntawv Pov Thawj rau txhua qhov khoom xa tuaj ntawm cov neeg siv khoom xav tau.
