Thaum cov neeg feem coob hnov 'kev tsim hlau', lawv pom ib tug txiv neej vuam ob daim hlau ua ke. Qhov ntawd yog ib feem ntawm nws, tseeb, tab sis nws zoo li hais tias ua noj tsuas yog nplawm lub lauj kaub. Zaj dab neeg tiag tiag pib txoj hauv kev ua ntej lub sparks ya, nrog kev xaiv ntawm cov khoom thiab cov txheej txheem los ua nws. Kuv tau pom ntau txoj haujlwm tau dai vim tias ib tus neeg tau teev cov 'steel' generic ntawm daim duab kos rau ib feem uas xav tau los tiv thaiv cov tshuaj ntsev tas li, lossis xaj kom muaj cov duab geometry nyuaj los ntawm cov txheej txheem tsim tsis raug, tshuab nyiaj txiag. Lub fabrication yog qhov kawg nkaus xwb; kev ua si yog sau nyob rau hauv lub foundry thiab lub tshuab khw.
Lub Foundation: Nws pib nrog Cast
Koj tsis tuaj yeem tsim qhov koj tsis muaj. Ntau ntawm peb txoj haujlwm pib nrog cov khoom nyoos. Qhov no yog qhov chaw uas cov tuam txhab uas muaj kev paub txog cov ntaub ntawv sib sib zog nqus, xws li Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), ua cov koom tes tseem ceeb. Lawv tau nyob hauv qhov kev ua si casting thiab machining rau ntau tshaj 30 xyoo, uas txhais tau hais tias lawv tau pom dab tsi ua haujlwm thiab ua tsis tau. Thaum lawv tham txog plhaub molding kom zoo dua nto tiav ntawm lub twj tso kua mis los yog peev casting rau qhov intricate turbine hniav nrog sab hauv, koj mloog. Nws tsis yog kev muag khoom xwb; nws yog raws li kaum xyoo ntawm pouring hlau.
Cov khoom siv spec yog lwm minefield. Stainless hlau tsis yog ib yam. Puas yog 304 rau kev tiv thaiv corrosion, lossis 316 rau cov chlorides? Los yog peb tab tom tham txog nickel-raws li alloy rau high-kub daim ntaub ntawv? Kuv nco qab txog ib txoj haujlwm rau cov neeg siv tshuaj lom neeg uas peb pib siv tus qauv 304 stainless fabrication. Nws dhau tag nrho cov kev ntsuam xyuas thawj zaug, tab sis nyob rau hauv rau lub hlis nyob rau hauv lub tshav pob, peb pib pom kev ntxhov siab corrosion tawg ntawm cov pob qij txha. Ib puag ncig muaj kab chlorides peb tsis tau suav rau. Peb yuav tsum tau rov ua dua tag nrho lub rooj sib txoos siv 316L. Qhov kev ua yuam kev ntawd yog ib zaj lus qhia phem nyob rau hauv cov ntaub ntawv science uas tsis muaj kev sib tham. QSY qhov kev paub nrog cov alloys tshwj xeeb xws li cobalt thiab npib tsib xee-raws li cov teeb liab yog ib qho teeb meem uas lawv nkag siab txog cov kev sib tw siab no.
Tau txais txoj cai casting yog 70% ntawm kev sib ntaus sib tua. Ib tug tsis zoo gated casting nrog sab hauv shrinkage los yog inconsistent phab ntsa thickness hloov tom qab hlau fabrication txheej txheem rau hauv npau suav phem ntawm warping thaum vuam los yog tsis yooj yim sua machining tolerances. Ib tug zoo foundry khub muab ib tug ze-net-zoo ib feem uas yog tiag fabricable.
CNC Machining: Qhov Precision Interlude
Tam sim no, lub casting tuaj txog. Nws yog tsis tshua muaj npaj bolt rau. Qhov no yog qhov twg CNC machining nkag mus rau hauv hlau fabrication kev ua haujlwm. Drilling bolt qauv, tig mus rau qhov chaw mounting, tsim kev sib khi grooves - qhov no yog kev ua haujlwm precision uas txhais tau tias qhov kev sib dhos zaum kawg haum zoo li cas. QSY koom ua ke qhov no, uas yog qhov zoo dua. Nws txhais tau hais tias tib pab neeg uas nkag siab txog cov txheej txheem casting thiab cov ntsiab lus kev ntxhov siab kuj tseem ua lub tshuab ua haujlwm. Lawv paub qhov twg kom tsis txhob noj hnyav dhau ntawm cov phab ntsa nyias, lossis yuav ua li cas kho qhov kev nqis peev zoo li qub tsis muaj qhov cuam tshuam.
Kuv tau kawm txoj kev nyuaj uas cais cov neeg muag khoom thiab cov neeg muag khoom tuaj yeem ua rau muaj kev thuam. Tus kws kho tshuab hais tias lub casting yog mos los yog txav, lub foundry hais tias lub tshuab yog siv tsis ncaj ncees lawm speeds / pub. Muaj nyob rau hauv ib lub ru tsev, zoo li ntawm lawv qhov chaw (koj tuaj yeem pom lawv txoj hauv kev ntawm https://www.tsingtaocnc.com), tshem tawm qhov ntawd. Lub voj kev tawm tswv yim yog tam sim ntawd. Yog hais tias ib lub cuab yeej yog chattering ntawm ib tug tshwj xeeb alloy batch, lawv muaj peev xwm kho cov machining tsis los yog txawm chij nws rov qab mus rau lub melting txheej txheem. Qhov kev sib koom ua ke no yog qee yam koj tsuas yog txaus siab tom qab ua haujlwm nrog lwm txoj hauv kev.
Lub hom phiaj ntawm machining nyob rau hauv fabrication prep tsis yog tsuas yog mus ntaus qhov ntev ntawm ib tug luam. Nws yog los tsim cov ntaub ntawv siv thiab cov yam ntxwv uas yuav tso cai rau tus neeg tsim khoom los sib sau ua ke cov khoom kwv yees. Ib txhiab ntawm ib nti yuam kev ntawm lub tshuab txiav ceg tuaj yeem txhais mus rau lub quarter-inch misalignment thaum koj tab tom sim vuam lub thav duab loj.
Fabrication Floor: Qhov Kev Xav Tau Raws Li Lub Teeb
Qhov no yog qhov ntxhov, nrov, thiab muaj koob meej. Koj tau txais koj cov machined castings, koj cov phaj txiav, koj cov khoom lag luam bar. Tam sim no txhua yam yuav tsum tau los ua ke. Vuam cov nickel-raws li alloy yog cov tsiaj nyaum sib txawv los ntawm cov hlau me me. Lub tshav kub input, interpass kub, muab tub lim hlau - nws yog ib daim ntawv qhia. Tau txais nws tsis ncaj ncees lawm, thiab koj precipitate carbides nyob rau hauv lub tshav kub-cuam tshuam cheeb tsam, ua rau nws nkig. Ib zaug peb yuav tsum tau txuas lub tes tsho cobalt alloy rau hauv lub tsev hlau. Qhov sib txawv thermal expansion ib leeg yog mob taub hau. Pre-heat, tshwj xeeb weld sequence, tswj txias-down ... nws zoo li kev sim chemistry.
Jigging thiab fixturing yog lub unsung heroes. Rau kev ua haujlwm rov ua dua tshiab, lub sijhawm siv los tsim cov khoom, kho jig them rau nws tus kheej kaum zaug. Tab sis rau ib-offs los yog prototypes, koj feem ntau improvising nrog clamps, hlau nplaum, thiab ib ntus tack welds. Qhov ua kom yuam kev yog paub thaum twg ib ntus tack yuav ua rau muaj kev ntxhov siab txaus los rub tag nrho lub rooj sib txoos tawm ntawm square. Qee lub sij hawm koj yuav tsum cia nws txav mus, tom qab ntawd kho nws, tsis yog sib ntaus sib tua rau hauv kev xa.
Distortion tswj. Qhov ntawd yog kev sib ntaus sib tua tas li. Koj tab tom thov khaus, thaj chaw tshav kub los koom nrog cov hlau, thiab lawv xav txav. Qhov sib lawv liag ntawm welds yog qhov tseem ceeb. Ntawm lub nqaj ntev nrog ntau lub stiffeners, koj tuaj yeem xaws weld hauv ib qho qauv tshwj xeeb, dhia ntawm sab mus rau sab, kom sib npaug ntawm rub. Qee lub sij hawm koj txawm tias ua ntej khoov cov khoom nyob rau hauv qhov kev taw qhia, cia siab tias lub vuam rub. Nws tsis yog ib qho kev tshawb fawb tseeb; nws yog kev xav thiab kev paub.
Zoo: Cov kauj ruam tsis pom
Fabrication tsis ua tiav thaum lub kawg weld hlaws yog nteg. Qhov ntawd yog thaum qhov kev tshuaj ntsuam pib. Kev soj ntsuam pom thawj zaug - nrhiav cov kab nrib pleb, undercut, porosity. Tom qab ntawd tuaj qhov kev sim uas tsis muaj kev puas tsuaj. Dye penetrant rau nto flaws ntawm cov tseem ceeb stainless los yog alloy welds. Tej zaum kev kuaj ultrasonic rau sab hauv tsis xws luag ntawm cov ntu tuab. Rau kev tsim cov khoom siv siab, kev sim hydrostatic yog qhov yuav tsum tau ua.
Tab sis ib qho tseem ceeb tshaj plaws, thiab feem ntau tsis saib xyuas, cov kauj ruam yog kev kho cua sov tom qab vuam (PWHT). Rau ntau cov hlau alloys thiab tshwj xeeb tshaj yog rau cov khoom siv hnyav, PWHT yog qhov tseem ceeb los txo cov kev ntxhov siab uas seem raug kaw los ntawm vuam. Nws yog ib lub sij hawm thiab lub zog-siv cov txheej txheem - sticking tag nrho cov sib dhos rau hauv lub qhov cub loj thiab coj nws mus rau ib tug tshwj xeeb kub rau ib lub sij hawm. Nws yog kev ntxias kom hla nws kom tau raws li lub sijhawm kawg, tab sis kuv tau pom qhov tshwm sim: cov ntaub ntawv loj heev rau lub compressor uas tawg audibly lub hlis tom qab tsuas yog zaum hauv ib lub vaj, tsuas yog los ntawm kev ntxhov siab sab hauv sim sib npaug.
Cov ntaub ntawv yog ib feem ntawm qhov zoo thiab. Cov ntaub ntawv tsim nyog tsim nyog, nrog rau cov ntaub ntawv pov thawj, cov txheej txheem weld specifications (WPS) siv, cov kab kos kev kho cua sov, thiab cov ntaub ntawv soj ntsuam, yog dab tsi hloov ib pawg ntawm cov hlau mus rau hauv ib qho traceable, txhim khu kev qha. Qhov no yog qhov kev koom tes nrog ib tus neeg muab kev pabcuam vertically integrated qhia nws tus nqi dua. Cov ntaub ntawv pov thawj los ntawm casting, machining cov ntaub ntawv, thiab cov ntaub ntawv fabrication tuaj yeem yog ib feem ntawm cov pob khoom sib txuas.
Integrated Advantage
Yog li, ncig rov qab. Muaj tseeb hlau fabrication tsis yog kev lag luam cais. Nws yog qhov tseem ceeb ntawm cov saw hlau: cov khoom siv xaiv, kev tsim (xws li casting), precision machining, thiab thaum kawg, koom thiab ua tiav. Thaum cov theem no siloed, koj poob ntaub ntawv. Tus neeg tsim khoom tsis paub tias vim li cas qee qhov chaw ntawm qhov casting nyuaj dua, tus kws kho tshuab tsis nkag siab txog qhov sib txuas uas yuav ua raws.
Tias yog vim li cas tus qauv ntawm lub tuam txhab zoo li QSY yog qhov nthuav. Kev khiav hauj lwm rau ntau tshaj 30 xyoo nyob rau hauv casting thiab machining muab lawv lub hauv paus kev nkag siab ntawm cov khoom tus cwj pwm los ntawm nws cov kua hauv lub xeev. Thaum lawv koom nrog lossis muab cov khoom siv rau kev tsim khoom, lawv nqa tag nrho cov keeb kwm mus rau lub rooj. Lawv tsis yog tsuas yog muag ib qho casting lossis machined block; lawv muag ib feem nrog cov yam ntxwv paub, kev coj tus cwj pwm nyob rau hauv lub teeb, thiab txo qis kev pheej hmoo ntawm kev poob qis.
Rau ib tus kws tshaj lij lossis tus thawj saib xyuas qhov project, qhov kev sib koom ua ke no yog ib qho cuab yeej txo kev pheej hmoo. Nws ua kom yooj yim rau cov saw hlau, ua kom nruj cov lus tawm tswv yim rau kev daws teeb meem, thiab ua rau muaj kev kuaj xyuas zoo ntawm ntau theem. Lub hom phiaj kawg ntawm fabrication tsis yog ua kom ib yam dab tsi zoo li daim duab. Nws yog los ua ib yam dab tsi uas ua tau, ntseeg tau, nyob rau hauv lub ntiaj teb tiag tiag. Thiab qhov kev ua tau zoo yog forged ntev ua ntej qhov kawg weld yog ua.
