Ua ntej, qib ntawm cov txheej txheem yog tsawg, qhov zoo ntawm precision casting khoom lag luam tsis zoo 1, casting teeb meem teeb meem yog qhov loj. 2, casting cuam tshuam loj heev thiab suav nrog cov teeb meem loj yog qhov loj heev. Loj nrum steel qhov chaw thiab cov khoom noj loj nyob hauv qhov kawg ntawm kev ua kom ruaj khov, hauv lub hauv paus ntawm lub qhov tso cua, casting cam seem muaj cov kab-macro-bias, grain coarse teeb meem. 3, cov ntawv thov analog software tsis nrov. Casting txheej txheem simulation yog qhov tsim nyog ntawm casting ntau lawm, nyob rau txawv teb chaws, yog tias tsis muaj lub computer simulation thev naus laus zis, koj tsis tuaj yeem txais qhov kev txiav txim. Tuam Tshoj lub hauv paus pib lub computer simulation pib thaum ntxov, txawm hais tias tseem ceeb suav ntawm ib feem ntawm kev tsim kho muaj peev xwm muaj zog, tab sis tag nrho software ntim peev txheej tsis zoo, ua rau cov khoom lag luam tsis muaj txiaj ntsig ntawm kev tsim software kom deb tom qab tsim tau lub teb chaws, ntau lub tuam txhab ntawm cov lag luam simulation thev naus laus zis, tsis txaus ntseeg. Txawm hais tias qhov xwm txheej no tau zoo zuj zus tuaj, tab sis kev yuav khoom ntawm kev lag luam casting simulation software qhauj, tuaj yeem ua nws lub luag haujlwm yog qhov tsis tshua muaj, qhov kev xav tau ceev ceev rau cov neeg ua haujlwm enterprise ua cov ntawv thov software. 4, lub peev xwm ntau lawm ntawm kev ua yeeb yam castings seem zoo, siab tshaj qhov peev txheej tsim khoom tsim yog tseem nyuaj, tseem ceeb thev naus laus zis thiab cov khoom tseem ceeb tseem cuam tshuam nrog kev ntshuam. 5, precision casting ua npoo yog loj. Vim tias tsis muaj lub tswv yim kev tsim qauv, cov txheej txheem tsim teeb tsa nyuaj los tswj cov teeb meem deformation nrog kev paub dhau los, cov txheej txheem kev ua lag luam yog feem ntau 1-3 npaug loj dua li txawv teb chaws. Kev ua haujlwm loj ntawm cov npoo, casting siv zog thiab khoom siv raw yog loj, lub sijhawm ua haujlwm ntev, kev tsim khoom tsis tshua muaj txiaj ntsig, tau dhau los ua ib qho kev txwv tsis pub nthuav tawm kev txhim kho kev lag luam. 6, kev tso dej tso cua tshuab tsim yog qhov tsis tsim nyog.
Vim tias cov qauv siv tsis raug, muaj qhov tsis xws xws li lub plhaw roj, suav nrog, uas ua rau kev tsim khoom tsawg thiab dhau tus nqi ntawm kev nrum. Thib ob, kev ua qias tuaj ib puag ncig phem, kev ua haujlwm tsis zoo nyob hauv Suav tsuas yog qee qhov kev lag luam loj xws li FAW, FAW, Ua Lag Luam Loj, Shenyang Dawn Tuam Txhab thiab lwm cov khoom siv ntau lawm, kev tshaj lij kev ua tiav casting technology, kev tiv thaiv ib puag ncig kev ntsuas yog qhov chaw, feem ntau cov khoom lag luam tsim khoom yog cov qub, rov qab thev naus laus zis, feem ntau tsis hais txog kev tiv thaiv ib puag ncig teeb meem. Thaum xyoo 1980, tsoomfwv tau hloov kho cov neeg ua haujlwm rau kev lag luam me, qis-thev naus laus zis thiab kev ua qias tuaj, uas ua rau muaj kev lag luam ntau ntxiv, tab sis cov yam ntxwv ntawm kev ua haujlwm ntau lawm tsis muaj kev hloov pauv.
Cov teeb meem ib puag ncig ntawm Tuam Tshoj lub hauv paus kev lag luam kuj tau tshwm sim nyob rau hauv kev siv ntau dhau ntawm cov khoom ntuj. Thib peb, kev siv hluav taws xob ntau thiab kev siv cov khoom nyoos Ntawm Tuam Tshoj qhov tseeb casting kev lag luam suav rau 25% -30% ntawm tag nrho lub zog noj ntawm lub tshuab kev lag luam, qhov nruab nrab ntawm kev siv lub zog yog 17%, kev siv lub zog yog kwv yees 2 zaug ntawm foundry tsim lub tebchaws. Tuam Tshoj lub zog siv rau 1 tuj tsim nyog cam khwb cia hlau qhov chaw rau 550-700 kg ntawm cov roj zeb txheem, txawv teb chaws 300-400 kg ntawm cov roj zeb txheem, Tuam Tshoj lub zog siv rau 1 tuj ntawm cov tsim nyog cam khwb cia steel qhov chaw rau 800-1000 kg ntawm txheem thee, 500 -800 kg ntawm txheem thee txawv teb chaws. Raws li kev txheeb cais, cov tswv yim ntawm cov ntaub ntawv thiab lub zog hauv cov txheej txheem ntau lawm ntawm kev ua si ntawm cov neeg suav ntawm kwv yees li 55% -70% ntawm cov txiaj ntsig tawm. Tuam Tshoj tus swb cov khoom hnyav yog 10% -20% siab dua qhov nruab nrab txawv teb chaws, ua yeeb yam steel ntau lawm yog nruab nrab 55%, nce mus txog 70% rau txawv teb chaws. Casting ntau lawm ua kom sov cov khoom siv spree yog mas npua hlau, seem hlau, coke, limestone, thiab lwm yam, xuab zeb, tseem ceeb xuab zeb. Feem ntau yog cov xuab zeb, av nplaum, hmoov txhuv, cob thiab lwm cov hlua khi, kho cov khoom siv, cov xuab zeb qub, xws li kev thauj khoom, xuab zeb, molding, tub ntxhais, ci, yaj, hliv, txias, xuab zeb, tu thiab tom qab kev kho mob thiab lwm cov txheej txheem, hauv cov ntsiab lus ntawm nws cov ntsiab lus ua haujlwm yog nqa tawm hauv tshuab kev co thiab suab nrov, qee tus kuj nyob hauv qhov kub siab melting, nchuav kev ua haujlwm, qee qhov tsim cov ntxhiab tsw ntxhiab, Cov hmoov av ua haujlwm ib puag ncig yog qhov phem tshaj. Cov kev piav qhia no piav qhia txog qhov hnyav ntawm ib puag ncig teeb meem hauv Tuam Tshoj qhov kev lag luam casting, thiab kev siv cov thev naus laus zis siab kom ua tiav qhov kev ua cov xim ntsuab yog qhov teeb meem tseem ceeb uas yuav tsum tau daws tam sim no.
