1. Dab tsi yog metallurgicalnruam nqus casting?

Metallurgical nruam nruam casting yog ib hom tshiab ntawm casting txoj kev uas melts hlau nyob rau hauv lub tshuab nqus tsev tej yam kev mob thiab txhaj nws mus rau hauv lub pwm los tsim cov khoom hlau los ntawm txias thiab solidification ntawm pwm. Nruam lub tshuab nqus tsev casting muaj qhov zoo dua li cov txheej txheem ib txwm muaj xws li kev ua haujlwm siab, siab precision, thiab qis zog noj.

2. Cov khoom siv feem ntau siv hauv lub tshuab nqus tsev casting

Cov khoom siv feem ntau siv rau lub tshuab nqus tsev casting feem ntau suav nrog lub tshuab nqus tsev, lub tshuab nqus tsev casting, casting pwm, thiab lwm yam. Ntawm lawv, lub tshuab nqus tsev yog cov cuab yeej tseem ceeb tsim nyog rau kev npaj cov khoom zoo, uas tuaj yeem muab lub tshuab nqus tsev ruaj khov los xyuas kom meej qhov zoo thiab kev ua haujlwm ntawm castings.

3. Txheej txheem thiab txheej txheem

Kev siv tshuab thiab cov txheej txheem ntawm lub tshuab nqus tsev tsis tu ncua yog qhov nyuaj, yuav tsum tau ua ntau yam xws li preheating, nqus tsev kho mob, melting, pouring, solidification, thiab lwm yam. thiab impurities nyob rau hauv cov hlau, kom ntseeg tau qhov zoo thiab nto smoothness ntawm lub casting.

4. Kev daws teeb meem rau cov teeb meem tshwm sim

Nyob rau hauv tus txheej txheem ntawm kev nruam nqus casting hauv metallurgy, cov teeb meem tshwm sim muaj xws li overheating ntawm crystallizer, hlau splashing, tsis zoo tso pa roj, thiab porosity. Cov txheej txheem los daws cov teeb meem no suav nrog kev txhim kho kev tsim cov crystallizer, kho cov cua sov, thiab txhim kho cov txheej txheem pouring.

5. Cov ntsiab lus

Daim ntawv thov ntawm metallurgical nruam lub tshuab nqus tsev casting tshuab tsis tsuas yog txhim kho qhov zoo thiab kev ua tau zoo ntawm castings, tab sis kuj txhim kho ntau lawm efficiency thiab txuag zog. Nrog rau kev txhim kho txuas ntxiv ntawm kev tsim khoom lag luam, metallurgical nruam lub tshuab nqus tsev casting yuav siv dav thiab dhau los ua cov cuab yeej tseem ceeb hauv kev lag luam casting yav tom ntej.

Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm lub tshuab nqus tsev casting?

Lub tshuab nqus tsev casting yog txheej txheem ntawm casting nyob rau hauv lub tshuab nqus tsev ib puag ncig, uas muaj ib co zoo thiab cov kev sib tw piv rau cov tsoos casting txoj kev. Nov yog qee qhov zoo thiab qhov tsis zoo ntawm lub tshuab nqus tsev casting:

Qhov zoo:

Cov khoom lag luam zoo: Lub tshuab nqus tsev ib puag ncig tuaj yeem txo qhov kev sib cuag ntawm cov hlau thiab cov pa roj xws li oxygen thiab nitrogen hauv huab cua, yog li txo cov oxidation thiab lwm yam kev ua qias tuaj, uas yuav pab tsim cov khoom zoo thiab cov khoom zoo thiab cov khoom siv hlau.

Precision tswj: Thaum lub tshuab nqus tsev casting txheej txheem, yam xws li kub, siab, thiab cua tuaj yeem tswj tau ntau dua, ua rau cov khoom muaj pes tsawg leeg thiab cov khoom zoo sib xws, yog li txhim kho qhov tseeb ntawm cov khoom.

Txo porosity thiab inclusions: Vim muaj cov ntsiab lus roj tsawg hauv lub tshuab nqus tsev ib puag ncig, nws pab txo cov porosity thiab suav nrog hauv casting, txhim kho cov uniformity thiab ntom ntawm cov khoom.

Tsim nyog rau siab melting point alloys: Nqus casting yog tsim rau casting ntawm high melting point hlau thiab alloys vim hais tias nyob rau hauv ib tug nqus tsev vacuum, lub melting point ntawm cov ntaub ntawv no yog txo, uas yuav pab tau zoo tswj cov txheej txheem casting.

Kev tiv thaiv ib puag ncig: Lub tshuab nqus tsev casting txheej txheem txo cov tiam roj thiab cov khoom pov tseg, ua rau nws tus phooj ywg zoo dua.

Qhov tsis zoo:

Cov cuab yeej siv siab: Cov cuab yeej siv lub tshuab nqus tsev feem ntau kim dua vim tias nws yuav tsum tau tsim tshwj xeeb thiab cov tshuab tswj tau zoo heev.

Kev tu kom yooj yim: Kev saib xyuas thiab kev ua haujlwm ntawm cov khoom siv nqus tsev vacuum yog qhov nyuaj, yuav tsum muaj kev txawj ntse thiab kev txawj ntse.

Kev ua haujlwm tsawg tsawg: Piv nrog rau qee cov txheej txheem casting, lub tshuab nqus tsev yuav muaj kev ua haujlwm qis dua, tshwj xeeb tshaj yog rau cov khoom loj.

Kev txwv tsis pub dhau ntawm daim ntawv thov: Lub tshuab nqus tsev casting feem ntau yog siv rau hauv cov teb uas xav tau cov khoom lag luam zoo thiab cov hlau purity siab, uas tuaj yeem tshwm sim heev thiab kim rau kev siv dav dav.

Zuag qhia tag nrho, lub tshuab nqus tsev casting yog ib qho kev siv tshuab siab heev uas tsim nyog rau cov chaw thov tshwj xeeb, thiab kev lag luam tawm ntawm qhov zoo thiab qhov tsis zoo nyob ntawm cov kev xav tau tshwj xeeb thiab cov kev xav tau.

Hasung lub tshuab nqus tsev nruam nruam casting yuav ua tau raws li qhov kev thov rau cov hlau zoo hauv ntau yam lag luam.
