Thaum cov neeg feem coob hnov 'cov tuam txhab lag luam xuab zeb', lawv pom ib qho tsaus, plua plav hauv pem teb, tsuas yog nchuav hlau rau hauv cov xuab zeb pwm. Qhov ntawd yog cov duab classic, tab sis nws tsuas yog kwv yees li 20% ntawm cov dab neeg niaj hnub no. Qhov kev sib tw tiag tiag, thiab qhov twg ntau qhov dej num tau derailed, tsis yog qhov casting nws tus kheej - nws yog txhua yam uas tshwm sim ua ntej cov hlau tsoo cov xuab zeb thiab ntev tom qab nws txias. Nws yog tus tsim tawm tswv yim, tus qauv tsim, tom qab casting machining, thiab cov khoom siv science tom qab nws. Yog tias koj tsuas yog yuav ib qho casting, tej zaum koj yuav tawm ntawm tus nqi - thiab kev ntseeg siab - ntawm lub rooj.
Lub hauv paus misconception: Nws tsuas yog ib yam khoom
Ntau pawg neeg yuav khoom kho cov xuab zeb casting raws li kev yuav khoom yooj yim. Xa ib daim duab, tau txais ib nqe lus, xaiv qhov pheej yig tshaj, tos rau qhov chaw. Txoj kev ntawd yog ib daim ntawv qhia rau mob taub hau. Cov txheej txheem xuab zeb casting yog ntau yam tsis txaus ntseeg, tab sis qhov kev siv ntau yam txhais tau tias qhov tshwm sim yog hyper-dependent ntawm lub foundry qhov kev txawj ntse. Qhov loj ntawm cov xuab zeb, cov txheej txheem binder (ntsuab xuab zeb vs. resin-bonded, piv txwv li), lub rooj vag tsim - cov no tsis yog cov ntsiab lus me. Lawv hais txog cov khoom siv kho tshuab, qhov chaw tiav, thiab qhov yuav tshwm sim ntawm qhov tsis xws luag xws li shrinkage porosity.
Kuv tau pom cov khoom tsim zoo nkauj tsis ua haujlwm hauv kev sim vim tias qhov chaw tsim khoom xaiv raws li tus nqi siv cov xuab zeb tsis zoo rau cov geometry, ua rau tsis sib haum xeeb. Cov duab kos tau hu rau qee qib ntawm cov hlau nplaum, thiab cov ntaub ntawv qhia txog kev sib tw, tab sis lub microstructure tsis zoo vim tias qhov cua txias hauv pwm tsis raug. Lub chaw tsim khoom tau ua raws nraim li cov ntawv luam tawm, tab sis cov ntawv luam tsis tau - thiab ua tsis tau - qhia txog cov txheej txheem kev tsim khoom. Qhov ntawd yog qhov sib txawv.
Qhov no yog qhov uas cov players ntev-tsim sib txawv lawv tus kheej. Nws tsis yog hais txog qhov muaj qhov cub loj dua; nws yog hais txog muaj cov metallurgical thiab txheej txheem engineering hauv tsev los coj tus qauv tsim. Ib lub tuam txhab zoo li Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), piv txwv li, nrog lawv 30 xyoo nyob rau hauv casting thiab machining, yuav muaj cov txheej txheem ingrained paub. Koj tuaj yeem pom lawv ntawm lawv qhov chaw, tsi.com. Lawv tsom tsis yog tsuas yog ua cov pwm; nws tau teev nyob rau ntawd: lawv ua ke plhaub molding thiab peev casting kev txawj ntse nrog CNC machining. Qhov ntawd yog lub teeb liab uas lawv tab tom xav txog tag nrho cov saw hlau tsim khoom, tsis yog thawj kauj ruam xwb.
Qhov tseem ceeb txuas: Los ntawm Casting rau Machining
Qhov no yog arguably tus overlooked tus nqi tsav tsheb. Cov xuab zeb casting tuaj nrog cov kaum sab xis, cov kab sib cais, thiab cov khoom siv ntau dhau (lub rooj vag thiab riser system). Machining nws mus rau qhov kawg qhov ntev yog muab. Tab sis yog tias tus neeg muag khoom casting thiab lub khw muag khoom yog cov chaw sib cais, koj tau txais qhov kev ua si liam. Tus kws kho tshuab pom qhov chaw nyuaj lossis qhov chaw tsis muaj chaw nyob, thiab nws yog kev sib ntaus sib tua ntawm nws qhov txhaum nws yog - lub chaw tsim khoom rau qhov tsis zoo los yog lub tshuab ua haujlwm rau kev txiav hnyav heev.
Integrated cov neeg muag khoom, qhov tseeb xuab zeb casting tuam txhab uas muag uas tseem lis machining, tshem tawm qhov ntawd. Lawv muaj tag nrho cov txheej txheem los ntawm molten hlau mus rau tiav ib feem. Ntawm QSY, lawv qhia meej txog kev ua haujlwm nrog cam khwb cia hlau, hlau, stainless, thiab cov alloys tshwj xeeb xws li cobalt thiab npib tsib xee. Machining cov no, tshwj xeeb tshaj yog cov superalloys, yog ib qho tshwj xeeb hauv nws tus kheej. Muaj cov casting thiab machining nyob rau hauv ib lub ru tsev txhais tau tias lawv muaj peev xwm optimize lub casting tsim rau machinability-tej zaum yuav ntxiv me ntsis ntxiv Tshuag nyob rau hauv ib tug lo lus nug ntawm yuav ua li cas paub lawv tus kheej CNC department yuav lis nws. Lawv twb tau tsim nyob rau hauv qhov distortion los ntawm kev kho cua sov ua ntej qhov kev txiav thawj zaug. Nws yog seamless.
Kuv nco qab txog qhov project valve lub cev hauv stainless 316. Cov qauv thawj zaug los ntawm cov chaw tsim khoom-tsuas yog machined tsis zoo, nrog cov cuab yeej chatter thiab ceev ntxig hnav. Peb tau coj qhov teeb meem mus rau ib qho chaw muab kev pabcuam. Lawv cov kev daws teeb meem yog hloov maj mam: lawv kho cov cua txias fins hauv pwm me ntsis los hloov cov solidification sequence, uas ua rau ib tug ntau uniform hardness nyob rau hauv cov cheeb tsam yuav tsum machined. Daim duab tsis hloov, tab sis qhov cam khwb cia yog ib qho yooj yim dua machinable. Qhov kev txhim kho ntawd tsuas yog los ntawm kev tswj hwm ob txheej txheem.
Kev xaiv cov khoom tsis yog ib daim ntawv qhia zaub mov xwb
Cov neeg siv khoom feem ntau tuaj hais, Kuv xav tau nws hauv stainless hlau. Okay, tab sis qhov twg? 304 rau General corrosion? 316 rau chlorides? Los yog CF8M cam sib npaug? Thiab nws puas yog rau cov qauv thauj khoom lossis tsuas yog cov dej ntim cia? Qhov kev xaiv ncaj qha cuam tshuam rau cov txheej txheem xuab zeb casting. Austenitic stainlesses muaj qhov txo qis qis-lawv xav tau cov txheej txheem muaj zog uas tsim los ntawm ib tus neeg paub txog qhov tshwj xeeb alloy tus cwj pwm.
Qhov no yog qhov uas hais txog cov alloys tshwj xeeb ntawm lub tuam txhab profile tseem ceeb. Yog ib xuab zeb casting tuam txhab teev nickel-based lossis cobalt-raws li alloys, nws qhia kuv tias lawv muaj peev xwm cuam tshuam nrog kev kub siab lossis kev siv cov kev pabcuam corrosive heev. Xav txog turbine Cheebtsam, twj impellers rau hnyav tshuaj. Cov no tsis yog cov hauj lwm txheem. Pouring cov alloys yuav tsum tau tswj qhov kub thiab txias, feem ntau nyob rau hauv cov huab cua tiv thaiv, thiab cov xuab zeb pwm chemistry yuav tsum tau sib xws kom tsis txhob muaj qhov tshwm sim saum npoo. Nws yog ib pab koomtes sib txawv los ntawm casting grey hlau rau lub counterweight.
Kuv tau ua yuam kev ib zaug, thawb rau cov khoom siv nickel alloy rau cov khoom siv hluav taws xob siab vim tias cov ntaub ntawv cov khoom zoo meej. Kuv tsis tau sab laj txaus nrog lub foundry ua ntej. Nws muab tawm cov hlau tsis muaj npe nrov rau kub tearing hauv cov ntu tuab nrog cov xuab zeb lawv siv. Peb yuav tsum thim rov qab, hloov mus rau qib castable ntau dua, thiab rov tsim dua tshiab rau cov khoom sib txawv me ntsis. Zaj lus qhia: xaiv cov khoom siv yog kev sib tham nrog tus foundry's metallurgist, tsis yog kev txiav txim siab engineering.
Cov ntsiab lus tsis zoo nkauj uas ua los yog tawg ib qhov project
Kev ua qauv. Nws yog tus nqi ua ntej txhua tus xav kom txo qis, tab sis nws yog lub hauv paus ntawm txhua yam. Ib tug pheej yig, warped ntoo qauv yuav tsim inconsistent pwm mus ib txhis. Rau kev ua haujlwm ntau lawm, kev nqis peev hauv qhov ruaj khov, qhov ruaj khov hlau qauv (feem ntau aluminium lossis hlau) yog tsis sib tham. Zoo xuab zeb casting tuam txhab uas muag yuav ua ntej txog qhov no. Lawv tuaj yeem tswj hwm tus qauv tsim rau koj, uas yog qhov txiaj ntsig loj.
Tom qab ntawd muaj cov ntaub ntawv zoo. Kev lag luam-qib casting tsuas yog tau txais kev tshuaj xyuas pom. Ib qho tseem ceeb tivthaiv xav tau cov ntaub ntawv pov thawj (cov ntawv xeem zeb), tejzaum nws yog radiographic lossis ultrasonic kuaj rau lub suab sab hauv, thiab thawj tsab ntawv tshuaj xyuas. Koj yuav tsum paub tias qib twg koj xav tau thiab xyuas kom tus neeg muag khoom muaj peev xwm sib tw. Lub khw uas tseem ua precision machining feem ntau yog teeb tsa rau qib ntawm cov ntaub ntawv no, raws li nws yog tus qauv hauv machining cov khw.
Lub sij hawm ua ntej yog lwm yam teeb meem. Cov neeg xav tias xuab zeb casting yog ceev vim nws yog ib qho yooj yim txheej txheem. Tsim cov qauv tshiab, tsim nyog rau thawj kab lus, teeb tsa cov kab molding - uas yuav siv sijhawm. Qhov tseeb pouring yog ceev. Kev teem sijhawm tiag tiag los ntawm tus kws tshaj lij cov khoom lag luam tso nyiaj rau tag nrho cov kauj ruam no. Kev cog lus ntawm ob lub lis piam ua ntej lub sij hawm rau ib qho tshiab, complex feem feem ntau yog tus chij liab.
Saib ntawm Kev Ua Haujlwm Hauv Ntiaj Teb tiag
Cia peb rov qab mus rau qhov piv txwv ntawm Qingdao Qiangsenyuan Technology Co., Ltd. (QSY). Lawv teev muaj peev xwm ntawm tsi.com pleev xim rau daim duab ntawm ib hom kev ua haujlwm tshwj xeeb.
