Thaum cov neeg feem coob hnov 'qhov tshwj xeeb alloy,' lawv xav txog cov ntawv tshwj xeeb: Inconel 718, Hastelloy X, CoCrMo, nrog rau lawv cov tensile zog thiab corrosion kuj tooj. Qhov ntawd yog kev lag luam pitch. Qhov tseeb ntawm lub khw hauv pem teb, tshwj xeeb tshaj yog nyob rau hauv complex peev castings thiab tom ntej machining, yog ib tug txawv tsiaj nyaum. Qhov sib txawv ntawm daim ntawv pov thawj cov khoom zoo meej thiab kev ua haujlwm zoo, txhim khu kev qha yog qhov chaw ua haujlwm tiag tiag. Nws tsis yog tsuas yog muaj cov alloy; nws yog hais txog kev nkag siab dab tsi tshwm sim rau nws los ntawm lub xeev molten mus rau qhov kawg.
Tshwj xeeb hauv Cov Alloys Tshwj Xeeb tsis yog Chemistry xwb
Ua ib qho kev thov: qhov kub-kub npib tsib xee-raws li alloy tivthaiv rau daim ntawv thov turbine. Tus neeg siv khoom muab AMS spec. Qhov ntawd yog txoj kab pib, tsis yog qhov kawg. Qhov 'tshwj xeeb' xwm pib nrog kev xa khoom. Tsis yog txhua tus tswv alloys lossis cov khoom siv nkauj xwb melts coj zoo ib yam. Cov ntsiab lus, qhov tseeb melting thiab refining txheej txheem ntawm lub zeb-cov subtly cuam tshuam castability thiab, tom qab, machinability. Peb tau kawm kom tsim nyog peb cov khoom siv tsis yog nrog cov ntaub ntawv xwb, tab sis nrog kev sim me me. Ib tus neeg muag khoom Inconel 625 tuaj yeem nchuav me ntsis txawv dua li lwm tus, cuam tshuam cov pwm sau thiab kev ncaj ncees kawg hauv cov ntu nyias.
Qhov no yog qhov chaw ua haujlwm mus sij hawm ntev. Ib lub tuam txhab zoo li Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), nrog nws peb lub xyoo caum hauv casting thiab machining, yuav pom ntau qhov kev hloov pauv hauv lub xyoo. Lub koom haum nco yog qhov tseem ceeb. Koj tsim lub tsev qiv ntawv puas siab ntsws: Source A's 316L yog qhov zoo rau cov li qub loj, tab sis rau qhov sib txawv ntawm lub plhaub pwm casting ntawm cov duab me me, qhov nyuaj, Qhov Chaw B lub tshav kub muaj qhov dej zoo dua. Qhov no tsis yog nyob rau hauv ib daim ntawv teev cov ntaub ntawv.
Cov txheej txheem casting nws tus kheej - txawm tias nws yog lawv lub plhaub tshwj xeeb pwm lossis peev casting - ua rau nws tus kheej 'kev hloov kho alloy.' Lub thermal dynamics thaum lub sij hawm solidification tsim lub microstructure. nrawm dhau, thiab koj yuav raug micro-porosity; qeeb dhau, thiab kev loj hlob ntawm cov nplej tuaj yeem ua rau tsis muaj zog. Rau cov alloys tshwj xeeb, lub qhov rais rau kev pom tsis zoo yog feem ntau nqaim. Kev kho cua sov tom qab-casting dhau los ua tsis yog sib tham, tsis yog ib qho kev xaiv, los daws kev ntxhov siab thiab ua tiav cov qauv tsim theem. Tau txais qhov tsis ncaj ncees lawm tuaj yeem ua rau lub zog muaj zog alloy qhov nkig.
Machining: Qhov twg Theoretical ntsib kev muaj tiag
Qhov no yog tus humbler loj. Koj muaj qhov zoo nkauj cam khwb cia cobalt-chromium alloy. Chemistry yog zoo meej, X-ray yog huv si. Tam sim no koj yuav tsum tau muab nws tso rau hauv lub tshuab CNC kom ua tiav nruj-tolerance bores thiab nto tiav. Qhov no yog qhov uas ntau qhov project ntsib cov nqi npaj txhij txog thiab qeeb.
Tshwj xeeb alloys ua hauj lwm harden. Ib qho cuab yeej txiav uas tsis kam, txawm tias ib pliag, tuaj yeem tsim txheej txheej nyuaj dua li lub cuab yeej nws tus kheej. Peb tau ruined kim inserts nyob rau hauv feeb kawm qhov no. Coolant tsis yog ua kom txias xwb; nws yog hais txog kev tiv thaiv kev ua haujlwm hnyav thiab ua kom cov nti khiav tawm. Lub siab tsis ncaj ncees lawm los yog hom tuaj yeem ua rau chip rov vuam. Cov tswv yim machining rau cov ntaub ntawv no yog kev tiv thaiv: zoo ib yam, aggressive txiav kom tau raws li kev ua hauj lwm-hardened txheej los ntawm yav dhau los pass, es tsis yog lub teeb, ceev faj skimming.
Toolpath programming yuav tsum tau them nyiaj rau qhov seem ntawm qhov seem casting stresses. Qee zaum, thaum koj clamp thiab tshuab ib sab, qhov txav me ntsis raws li kev ntxhov siab sab hauv rebalance. Nws ntxhov siab heev. Tej zaum koj yuav tuav kam rau ntawm thawj qhov kev ua haujlwm, tsuas yog nrhiav kev cuam tshuam tom qab unclamping. Qhov no feem ntau ua rau ib ntu ntawm kev ua haujlwm ntxhib, lub voj voog kev ntxhov siab, tom qab ua tiav machining. Nws tsis yog txoj kev ceev tshaj plaws, tab sis nws ntseeg tau. Lawv integrated CNC machining kev muaj peev xwm yog qhov tseem ceeb ntawm no-muaj casting thiab machining nyob rau hauv ib lub ru tsev tso cai rau qhov kev rov ua dua, tawm tswv yim-tsav txheej txheem yam tsis muaj kev thuam ntawm cov neeg muag khoom sib cais.
Failure Points thiab Subtle Compromises
Tsis yog txhua zaj dab neeg yog kev vam meej. Thaum ntxov, peb muaj ib qhov project rau corrosion-resistant nickel alloy ib feem rau kev lag luam tshuaj. Nws dhau tag nrho cov qauv xeem. Tab sis nyob rau hauv qhov kev pab cuam, nws ua tsis tau tejyam los ntawm kev nyuaj siab corrosion cracking nyob rau hauv ib tug tshwj xeeb crevice geometry peb tsis tau suav hais tias ib tug hotspot. Zaj lus qhia? Ib puag ncig yog txhua yam. Ib qho 'tshwj xeeb alloy' tsuas yog tshwj xeeb rau cov xwm txheej tshwj xeeb. Tam sim no peb siv sijhawm ntau los tham txog qhov chaw ua haujlwm-cov tshuaj muaj pes tsawg leeg, qhov kub thiab txias, kev thauj khoom cyclic-raws li peb ua cov ntawv luam tawm.
Lwm qhov kev pom zoo sib xws yog nruab nrab ntawm kev tsim qauv tsim qauv thiab kev tsim khoom. Tus tsim qauv yuav qhia cov phab ntsa nyias nyias thiab cov kaum sab hauv hauv cov hlau tsis muaj hlau kom txuag tau qhov hnyav. Tab sis cov hlau molten puas tuaj yeem sau seem ntawd yam tsis tau txias ua ntej? Lub cuab tam puas tuaj yeem ncav cuag lub kaum sab hauv rau kev ua haujlwm lossis kev tshuaj xyuas? Qee lub sij hawm, cov tswv yim tseem ceeb tshaj plaws yog tawm tswv yim me ntsis kev tsim tweak - lub vojvoog nce ntawm 0.5mm, kev hloov kho lub kaum sab xis - uas ua rau qhov ua tau zoo yam tsis muaj kev cuam tshuam. Qhov no yog kev sib koom ua ke uas txhais tau tias muaj kev vam meej.
Kev pov thawj zoo kuj tau txais kev dag ntxiv. Dye penetrant testing yog tus qauv, tab sis rau qhov tseem ceeb ntawm kev ntseeg siab, peb feem ntau thawb ntau dua. Piv txwv li, radiography los soj ntsuam rau sab hauv porosity nyob rau hauv lub casting qhov tseem ceeb seem. Nws ntxiv cov nqi thiab sijhawm, tab sis hla nws yog kev twv txiaj. Qhov kev txiav txim hinges rau ntawm qhov kev ua haujlwm. Puas yog tus qauv thauj khoom lossis lub tsev tsis tseem ceeb? Lub sij hawm 'tshwj xeeb alloy qhov chaw' txhais tau hais tias lub luag haujlwm tshaj li qhov qub, yog li peb cov txheej txheem tshuaj xyuas feem ntau yuav tsum ua kom haum qhov kev cuam tshuam ntawd.
Integrated Advantage: Los ntawm Melt rau Tshuab
Qhov no yog vim li cas tus qauv ntawm lub foundry nrog rau hauv tsev machining, zoo li ib tug piav nyob rau hauv https://www.tsingtaocnc.com, ua rau kev nkag siab rau cov ntaub ntawv no. Lub voj kev kawm yog nruj. Pab pawg machining tuaj yeem qhia ncaj qha rau pab pawg casting, Cov khoom siv no muaj qhov nyuaj ntawm no, ua cov cuab yeej hnav ntau dhau. Pab pawg casting tuaj yeem tshawb xyuas: nws puas yog qhov hloov pauv me ntsis hauv qhov ntsuas kub? Kev hloov kho rau lub rooj vag system? Cov lus teb no yog kub.
Nws kuj tso cai rau kev ua kom zoo dua qub. Piv txwv li, txiav txim siab npaum li cas cov Tshuag tawm mus rau machining. Ntau dhau, thiab koj nyob nraum nkim kim alloy thiab machining lub sij hawm. Tsawg dhau, thiab kev hloov pauv me ntsis lossis qhov tsis zoo ntawm qhov chaw txhais tau tias qhov tsis tuaj yeem raug ntxuav kom ntev. Muaj ob pawg nyob rau hauv ib lub ru tsev tso cai rau koj txiav txim siab qhov kev pom zoo rau ib feem geometry thiab alloy.
Tsis tas li ntawd, kev tuav pov hwm yuav muaj kev txhawj xeeb. Tshwj xeeb alloy qhov chaw, tom qab-casting thiab nruab nrab ntawm machining ops, feem ntau muaj nuj nqis thiab rhiab heev. Khaws lawv nyob rau hauv ib puag ncig tswj, taug qab lawv nyob ze, thiab txo qis kev thauj mus los txo qhov kev pheej hmoo ntawm kev sib xyaw, kev puas tsuaj, lossis kev sib kis. Ib qho chaw sib xyaw ua kom yooj yim rau cov saw hlau logistics no ntau heev.
Saib tom ntej: Nws tseem yog Khoom siv tes ua
Txawm hais tias tag nrho cov kev nce qib hauv kev simulation software rau casting (xws li MAGMA) thiab CNC programming, tsim cov khoom siv hlau tshwj xeeb saum toj kawg nkaus tseem yog cov khoom siv ua haujlwm zoo heev. Lub software muab koj qhov pib qhov tshwm sim, tab sis tus kws ua haujlwm - tus kws tsim khoom tsim, tus kws kho tshuab - ua qhov kev hloov kho zaum kawg raws li qhov pom, suab, thiab hnov. Txoj kev uas cov hlau nchuav, xim ntawm cov nti thaum lub sij hawm machining, lub suab ntawm kev txiav.
Lub neej yav tom ntej, kuv xav tias, nyob rau hauv kev ntes ntau qhov kev paub tsis meej no. Tab sis rau tam sim no, nws nyob hauv cov neeg thiab cov koom haum kev coj ua ntawm cov tuam txhab uas tau dhau los ntawm cov voj voog, zoo li kev ua haujlwm 30 xyoo yuav muaj. Lawv tau tshawb nrhiav cov khoom tsis txaus, hloov mus rau cov qib alloy tshiab, thiab tau nqis peev hauv txoj cai CNC tshuab txiav lawv.
Yog li, thaum ntsuas qhov chaw rau tshwj xeeb alloy qhov chaw, saib dhau ntawm daim ntawv teev cov khoom thiab lub tshuab nres. Tshawb nrhiav pov thawj ntawm qhov kev sib koom ua ke, kev daws teeb meem kev xav. Nug txog ib txoj haujlwm nyuaj uas lawv tau ua tiav. Cov lus teb yuav qhia koj ntau tshaj li daim ntawv qhia glossy puas tau. Cov khoom tiag tiag tsis yog qhov alloy xwb; nws yog qhov kev paub siv uas ua kom cov haujlwm ua haujlwm raws li qhov xav tau, ntseeg tau, qhov twg nws suav.
