Raws li ib qho kev lag luam thaum ub, kev lag luam tsim tau ua rau cov kev loj hlob thiab kev vam meej ntawm tib neeg kev vam meej thaum lub sij hawm ntau txhiab xyoo ntawm tib neeg txoj kev loj hlob. Ua ntej 5000 xyoo dhau los hauv Cheeb Tsam Dynasty, nws raug hu ua txuj ci tseem ceeb hauv lub ntiaj teb uas ntim cov khob haus cawv, chim siab rau cov twj suab paj nruag, tshuab raj tooj rau kev pe hawm, thiab riam phom rau kev ua tsov ua rog. Bronze casting yog tsim los heev. Tag nrho 64 bronze tau pom nyob rau hauv Qixian County, Hubei. Tag nrho qhov hnyav tau ntau tshaj 5 tons. Qhov tseeb, nws zoo nkauj, zoo nkauj nrum, nplua zoo, thiab zoo siab rau pob ntseg thaum nws raug ntaus. Nws yog qhov tob tob thiab ncaj ncees, thiab lub suab nkauj yog qhov sib haum xeeb thiab kev zoo siab. Nyob rau hauv lub Han Dynasty, cam khwb cia hlau casting tau ua ib tug scale. Muaj ntau yam khoom siv coj los ua, cov nplawm thiab cov ntoos kabmob, cov txivneej zoo nkauj, hlau nees, Fang Ding, ntau yam. Archaeological pom tias malleable cam khwb cia hlau twb twb siv nyob rau hauv Suav teb. Txawm li cas los xij, nyob rau xyoo 1670, sab hnub poob tau tsim lub plawv dawb malleable cam hlau. Cov cuab yeej siv hlau cam hlau nyob hauv tebchaws Suav xyoo dhau los yog tshaj 1,000 xyoo dhau los tshaj nyob hauv Europe.
Ua rau xyoo pua 20th, txoj kev loj hlob sai ntawm kev pov thawj, ib qho ntawm cov tseem ceeb tshaj plaws yog qhov kev kawm ntawm cov khoom siv cuab yeej technology, yuav tsum tau siv txhua yam ntawm cov khoom sib xws ntawm lub casting zoo dua, thaum tseem muaj kev ua haujlwm zoo qhov ua tiav; Lwm qhov laj thawj yog kev ua lag luam kev lag luam thiab lwm yam Kev loj hlob ntawm kev lag luam xws li tshuaj lom neeg thiab kev ua twj paj nruag tau tsim cov khoom zoo rau cov chaw lag luam tsim khoom. Nyob rau hauv ntau tshaj 50 xyoo txij li thaum nrhiav ntawm Neeg lub Tuam Tshoj ntawm Tuam Tshoj, lub ntiajteb txawj nqus casting kev lag luam nyob rau hauv Tuam Tshoj tau zus los ntawm kos. Gravity casting ntau lawm tau tiav kev loj hlob. Nrog txoj kev lag luam xws li tsheb, maus taus, khoom siv hauv vaj hauv tsev, thiab cov tshuab computer, qhov kev thov rau lub qhov ntaiv loj ntxiv tau nce. , los tsim cov khoom zoo, kev txiav txim siab, lub ntiajteb txawj nqus casting qhov chaw ntawm lub ntiajteb txawj nqus kev lag luam tau ua kev loj hlob thiab kev loj hlob.
Tam sim no, Tuam Tshoj tus tsim txhua xyoo ntawm castings tau tshaj 31 plhom tons, qeb duas thawj hauv lub ntiaj teb, thiab nws yog lub ntiaj teb ua yeeb yam thiab lub teb chaws. Vim hais tias qhov zoo ntawm cov khoom nyob rau hauv lub lag luam foundry yog tsis guaranteed, thiab cov nqi qis yog siab, nyob rau hauv cov kev mob ntawm Tuam Tshoj tus kho thiab qhib thiab kev loj hlob kev lag luam, thiab kev sib tw tsiv thoob ntiaj teb kev lag luam, nruj tswj ntawm casting ntau lawm yuav tsum tau xyuas kom zoo ntawm cov yeeb yam. Kev txhim kho cov voj voog ntawm kev sim, kev txo cov nqi ntawm kev tsim, kev ua kom muaj kev sib tw, kev txhim kho kev lag luam, thiab kev ua haujlwm kom zoo dua qub thiab kev tsim kho dua tshiab rau cov kev lag luam thiab kev tsim ntawm lub teb chaws kev khwv nyiaj txiag mus rau txoj kev loj hlob zoo thiab ua haujlwm zoo.
Los ntawm cov 60s thaum ntxov, cov khoom siv simulation technology raug xub thawj siv los ua cov kev ntsuas kub ntawm kev tshawb fawb. Tom qab xyoo tas los ntawm kev siv zog, kev tsim cov tshuab computer simulation rau casting pwm solidification txheej txheem tau nkag mus rau theem ntawm cov tswv yim engineering, casting txheej txheem tsim thiab kev siv thiab Nws yog maj mam txav los ntawm kev paub txog science. Nyob rau hauv xyoo tas los no, nrog rau kev loj hlob ntawm lub tshuab computer, computer-aided tsim cov txheej txheem kev pov thawj, kev sim zauv ntawm casting solidification txheej txheem thiab ntau lwm technologies tau ntau thiab ntau dav siv hauv engineering foundry engineering. Lub tshuab ua lej sim ntawm txoj kev ua tus casting plays lub luag dej num hauv kev hloov thiab kho kom zoo dua qub cov cuab yeej casting technology, txo cov khoom nqi, thiab kev txhim kho cov kev sib tw ntawm lub tuam txhab lub tuam txhab. Nws daim ntawv thov uas nws kim heev yuav coj kev lag luam loj loj thiab kev sib raug zoo rau kev ua lag luam.
Cov kev ua lej hais txog kev ua lej hais txog kev ua kom muaj kev sib raug zoo ntawm cov kev sib tw nrog ntau yam muaj xws li ob peb lub tswv yim ntawm kev ua kom tiav, kev muab xam, kev sib tw ua tiav thiab kev xa tom qab. Lub simulation ntawm cov txheej txheem solidification ntawm casting suav nrog qhov muab xam ntawm qhov chaw kub thiab qhov twv ua ntej ntawm shrinkage shrinkage thiab shrinkage. Nws yog hu ua los ntawm cov kws tshawb fawb ua ib qho kev sim ntawm lub cev ntawm txoj kev pov thawj. Tam sim no, qhov dav simulation ntawm kub teb tau loj, thiab twv ntawm cov tsis xws li shrinkage thiab shrinkage tau kuj tau kawm tob. Rau zauv simulation software, lub twv ua ntej ntawm shrinkage thiab shrinkage yog ib lub ntsiab ntawm cov ntsiab lus solidification, thiab nws tseem yog ib qho ntawm lub ntsiab functions ntawm feem ntau solidification simulation software. Txawm li cas los, cov qib thiab daim ntawv thov software tseem tsis zoo meej.
ADC12 aluminium-silicon alloy muaj lub zog siab thiab corrosion kuj, me me thermal expansion coefficient, zoo kev kawm zoo thiab zoo nkauj casting zog yog dav siv nyob rau hauv automotive lub tog raj kheej thaiv, lub tog raj kheej taub hau, locomotive shock absorber, cav iav kem, agricultural machinery iav kem thiab lwm yam xoom qhov. Nyob rau hauv xyoo tas los no, nrog txoj kev loj hlob ntawm tsheb thiab maus taus kev lag luam, cov duab ntawm lub nres qhov chaw nres tsheb thiab qhov chaw nyob hauv lub tsev me me kuj tsis yooj yim, thiab lub zog thiab qhov muaj tseeb yuav tsum tau ua kom tau ntau ntau. Me me.
