Product Advantages thiab Disadvantages

Qhov zoo ntawm cov xuab zeb castings

1. Piv nrog rau lwm txoj kev casting, Sand casting muaj qhov zoo ntawm cov nqi qis, cov txheej txheem tsim khoom yooj yim thiab luv luv luv. Yog li ntawd, li ntawm 60 feem pua ​​​​mus rau 70 feem pua ​​​​ntawm tag nrho cov zis ntawm castings yog tsim los ntawm xuab zeb casting. Kwv yees li 70 feem pua ​​​​ntawm cov xuab zeb casting yog tsim los ntawm av nplaum xuab zeb. Hauv cov av nplaum xuab zeb pwm, cov txheej txheem av nplaum ntub dej yuav tsum yog thawj qhov kev xaiv (qhov hnyav ntawm qhov casting tuaj yeem yog li ntawm ob peb kilograms mus rau kaum ob kilograms). tons) lossis lwm hom xuab zeb.

Feem ntau, rau cov castings loj thiab nruab nrab, resin tsis muaj ci xuab zeb pwm tuaj yeem siv rau cam khwb cia hlau; dej iav xuab zeb moulds lossis resin tsis muaj ci xuab zeb pwm tuaj yeem siv rau steel castings.

Thaum qhov tseeb casting, nto zoo, cov khoom ntom ntom, metallographic qauv, cov khoom siv kho tshuab thiab lwm yam kev ua haujlwm siab dua, cov qauv tsim tshwj xeeb yuav tsum tau siv, xws li peev casting, siab casting, tsis tshua muaj siab casting, khoom casting, thiab lwm yam.

2. Cov txheej txheem casting yuav tsum tau ua raws li cov khoom tsim tawm

(1) Sand casting yuav tsum xav txog cov hauv qab no:

Rau cov chaw tsim khoom loj, kev siv thev naus laus zis ua qauv thiab cov txheej txheem tseem ceeb yuav tsum tau siv. Rau cov me me castings, ib lub thawv tsis muaj qhov siab molding kab yog siv rau kab rov tav parting los yog ntsug parting, nrog rau siab productivity thiab me me hneev taw. Rau nruab nrab-qhov loj me castings, ntau yam high-pressure molding kab thiab roj punch molding kab yog siv los ua kom tau raws li qhov yuav tsum tau ceev thiab high-precision molding ntau lawm kab. Cov txheej txheem ua cov tub ntxhais tuaj yeem xaiv tau: lub thawv txias tub ntxhais, lub thawv kub tub ntxhais, lub plhaub tub ntxhais thiab lwm txoj hauv kev ua tau zoo. Lub qub-fashioned zhenshi molding tshuab ntau lawm kab muaj cov khoom tsim tau qis, kev siv zog siab thiab lub suab nrov, thiab tsis ua raws li qhov yuav tsum tau ua ntawm ntau lawm, yog li nws yuav tsum tau hloov maj mam.

(2) Rau nruab nrab ntim loj castings, resin tsis muaj ci xuab zeb tuaj yeem siv rau molding thiab core ua.

(3) Ib qho me me batch ntau lawm ntawm hnyav castings, phau ntawv qauv tseem yog ib qho tseem ceeb. Kev tuav molding tuaj yeem hloov mus rau ntau yam kev xav tau, thiab tsis tas yuav siv ntau cov txheej txheem. Koj tuaj yeem xaiv dej iav xuab zeb molding, VRH dej iav xuab zeb molding, organic ester dej iav nws tus kheej-hardening xuab zeb molding, av nplaum qhuav molding, resin tus kheej teem xuab zeb molding, cement sand molding, thiab lwm yam. Rau qhov tseem ceeb castings uas tsim nyob rau hauv ib qho, lub qhov zoo li tus nqi qis thiab muab tso rau hauv ntau lawm sai. Rau cov khoom tsim los yog cov khoom siv ntev ntev, nws yog qhov tsim nyog siv cov xuab zeb ua qauv thiab cais lub thawv qauv. Txawm hais tias thawj zaug peev hauv pwm thiab cov thawv xuab zeb yog qhov siab, nws tuaj yeem raug them nyiaj los ntawm kev txuag cov qauv txiv neej-teev thiab txhim kho cov khoom zoo.

(4) Kev tsim tshwj xeeb suav nrog kev ua haujlwm qis, siab casting, centrifugal casting thiab lwm txoj kev casting. Vim yog cov khoom kim heev thiab cov pwm, nws tsuas yog tsim rau kev tsim khoom loj.

3. Casting txoj kev yuav tsum haum rau lub Hoobkas tej yam kev mob

Cov tuam txhab sib txawv muaj cov khoom siv sib txawv (cov khoom siv, qhov chaw, cov neeg ua haujlwm zoo, thiab lwm yam), kev tsim khoom, thiab kev tsim khoom. Raws li cov xwm txheej no, kev txiav txim siab yuav tsum tau muab rau kev xaiv cov qauv tsim qauv tsim nyog rau lub Hoobkas. Piv txwv li, nyob rau hauv zus tau tej cov loj-scale tshuab cuab tam txaj castings, lub qhov feem ntau yog siv los ua cov tub ntxhais, thiab cov xuab zeb lub thawv thiab cov qauv tsis ua. Qee lub tuam txhab siv cov qauv xuab zeb.

4. Yuav tsum coj mus rau hauv tus account qhov tseeb thiab tus nqi ntawm castings

Qhov tseeb ntawm castings tau los ntawm ntau txoj kev casting yog qhov sib txawv, kev nqis peev thiab kev tsim khoom lag luam kuj txawv, thiab cov txiaj ntsig kev lag luam kawg kuj txawv. Yog li ntawd, kom ua tiav "zoo, kev lag luam, ntau dua, nrawm dua", peb yuav tsum coj mus rau hauv tus account txhua yam. Kev kwv yees tus nqi ua ntej yuav tsum tau ua rau txoj kev xaiv casting los txiav txim siab cov txheej txheem casting nrog cov txiaj ntsig kev lag luam siab thiab lav qhov zoo ntawm castings.

Defects ntawm xuab zeb castings

Qhov tsis xws luag ntawm cov xuab zeb castings yog: rwb thaiv tsev txias, tsis txaus pouring, pores, xuab zeb sticking, xuab zeb inclusion, xuab zeb qhov, thiab o ntawm cov xuab zeb.

1) Kev sib cais txias thiab dej tsis txaus

Yog hais tias cov kua hlau filling muaj peev xwm tsis txaus, los yog cov txheej txheem filling tsis zoo, cov kua hlau yuav tsum tsis txhob ntws ua ntej cov kab noj hniav puv, uas yuav ua rau cov dej tsis txaus los yog cov txheej txheem txias txias hauv qhov casting. Thaum lub pouring tsis txaus, lub casting yuav tsis muaj peev xwm kom tau ib tug tiav zoo; Thaum lub caij txias cais, txawm hais tias lub casting tuaj yeem tau txais cov duab tiav, cov khoom siv ntawm cov casting raug puas tsuaj loj vim muaj qhov tsis tiav fused seams.

Tiv thaiv kom tsis muaj dej txaus thiab kev sib cais txias txias: nce qhov kub thiab txias ntawm qhov sib tov.

2) Lub plab

Cov roj tsis tau khiav tawm hauv lub sijhawm ua ntej cov kua hlau ua kua ua kua, thiab qhov tsis xws li qhov zoo li yog tsim nyob rau hauv casting. Cov phab ntsa sab hauv ntawm lub qhov hws yog du, ci los yog me ntsis oxidized. Tom qab cov pores tsim nyob rau hauv lub casting, nws zoo bearing cheeb tsam yuav raug txo, thiab kev nyuaj siab concentration yuav tshwm sim nyob ib ncig ntawm lub qhov hws kom txo tau qhov cuam tshuam tsis kam thiab qaug zog ntawm lub casting. Pores kuj tseem tuaj yeem txo qhov compactness ntawm casting, ua rau qee qhov castings uas yuav tsum tau kuaj hydrostatic yuav tsum tau muab pov tseg. Tsis tas li ntawd, porosity kuj adversely cuam tshuam rau corrosion kuj thiab kub tsis kam ntawm casting.

Tiv thaiv cov tiam ntawm pores: txo cov huab cua hauv cov hlau molten, ua kom cov huab cua permeability ntawm cov xuab zeb pwm, thiab ntxiv ib qho cua riser ntawm qhov siab tshaj plaws ntawm cov kab noj hniav.

3) nplaum xuab zeb

Muaj ib txheej ntawm cov xuab zeb uas nyuaj rau tshem tawm ntawm qhov casting hu ua nplaum xuab zeb. Cov xuab zeb nplaum tsis tsuas yog cuam tshuam rau cov tsos ntawm castings, tab sis kuj ua rau kev ua haujlwm ntawm casting tu thiab txiav, thiab tseem cuam tshuam rau lub neej ntawm lub tshuab. Piv txwv li, thaum muaj cov xuab zeb nplaum ntawm qhov chaw ntawm cov hniav cam, nws yooj yim rau kev puas tsuaj. Yog tias muaj cov xuab zeb nplaum hauv lub tshuab xws li cov twj tso kua mis lossis lub cav, nws yuav cuam tshuam rau cov dej ntws xws li roj, roj, roj lubricating thiab dej txias, thiab yuav stains thiab hnav tag nrho lub tshuab.

Tiv thaiv cov xuab zeb nplaum: ntxiv pulverized thee rau cov xuab zeb molding, thiab siv cov xuab zeb pleev xim rau saum npoo ntawm cov pwm.

4) Xuab zeb suav nrog

Cov grooves thiab caws pliav tsis xws luag tsim nyob rau saum npoo ntawm casting yog yooj yim heev los tsim thaum casting tuab thiab loj ca castings nrog ntub pwm.

Feem ntau ntawm cov khoom uas tsim cov xuab zeb nyob rau hauv lub casting yog nyob rau hauv kev sib cuag nrog lub Upper nto ntawm cov xuab zeb pwm. Lub sab sauv ntawm kab noj hniav yog cuam tshuam los ntawm radiant tshav kub ntawm molten hlau, uas yog ib qho yooj yim rau koov thiab warp. Thaum cov xuab zeb warped tsis tu ncua scoured los ntawm cov hlau molten yuav tawg thiab tawg, nyob twj ywm hauv qhov chaw lossis nqa mus rau lwm qhov chaw. Qhov loj dua qhov saum npoo ntawm qhov casting, qhov loj dua qhov ntim ntawm cov xuab zeb molding thiab ntau dua qhov nyiam ua cov xuab zeb inclusions.

5) Trachoma

Ib lub qhov zoo li qhov tsis xws luag uas muaj cov xuab zeb molding sab hauv lossis ntawm qhov chaw ntawm lub casting.

6) Kev nthuav dav xuab zeb

Thaum pouring, nyob rau hauv lub siab ntawm cov hlau molten, phab ntsa ntawm cov pwm txav, thiab cov casting yog ib nrab swelled los tsim ib tug tsis xws luag. Txhawm rau tiv thaiv cov xuab zeb nthuav dav, lub zog ntawm cov xuab zeb pwm, rigidity ntawm lub thawv xuab zeb, lub zog lub thawv quab yuam los yog lub zog nruj thaum kaw lub thawv yuav tsum tau nce, thiab lub ncuav kub yuav tsum tau txo kom tsim nyog los ua kom qhov chaw ntawm qhov chaw. molten hlau crust ua ntej, thiaj li yuav txo tau qhov cuam tshuam ntawm molten hlau rau ntawm pwm. siab.
