Kev sib txuas lus Cavity Titanium Alloy Poob-Wax Casting

Cov hauv qab no yog ib qho kev soj ntsuam tag nrho ntawm qhov ploj - siv quav ciab ntawm titanium alloy kev sib txuas lus kab noj hniav:

Raws li qhov tseem ceeb hauv cov khoom siv sib txuas lus, kab noj hniav sib txuas lus muaj kev ua haujlwm nruj heev hauv ntau yam. Hluav taws xob, nws xav tau zoo heev electromagnetic shielding los tiv thaiv electromagnetic cuam tshuam thiab xyuas kom ruaj khov teeb liab kis tau tus mob. Qhov no yuav tsum muaj kev tsim qauv tsim nyog, thiab cov khoom siv conductivity thiab permeability yuav tsum ua tau raws li cov qauv tshwj xeeb. Mechanically, nws yuav tsum tiv taus qee yam kev cuam tshuam sab nraud thiab kev co los tiv thaiv kev deformation lossis kev puas tsuaj hauv qhov chaw ua haujlwm nyuaj, yog li xav tau lub zog txaus thiab hardness. Nyob rau tib lub sijhawm, qhov tseeb qhov tseeb ntawm kev sib txuas lus kab noj hniav yog qhov siab heev; Txawm tias qhov sib txawv ntawm qhov sib txawv ntawm feeb tuaj yeem cuam tshuam rau kev sib dhos nrog lwm cov khoom siv thiab kev ua haujlwm hluav taws xob tag nrho. Tsis tas li ntawd, qhov zoo ntawm qhov chaw yog qhov tseem ceeb; ib tug du nto pab txo cov teeb liab xav txog thiab tawg, txhim kho kev sib txuas lus efficiency.

Titanium alloys, nrog lawv cov khoom zoo, yog cov khoom siv zoo tshaj plaws rau kev tsim cov kab noj hniav sib txuas. Ua ntej, lawv muaj lub zog tshwj xeeb, txhais tau tias lub zog siab - rau - qhov sib piv ceev. Qhov no tso cai rau kev txo qhov hnyav thaum tswj cov kab noj hniav kom muaj zog, uas yog qhov tseem ceeb rau kev nrhiav lub teeb yuag thiab cov qauv me me hauv cov khoom siv sib txuas lus niaj hnub no. Thib ob, titanium alloys muaj kev tiv thaiv corrosion zoo heev, ua kom ntev - siv nyob rau hauv ib puag ncig hnyav xws li av noo thiab kub kub yam tsis muaj corrosion, yog li ncua kev pab cuam lub neej ntawm kev sib txuas lus kab noj hniav. Tsis tas li ntawd, titanium alloys pom zoo thermal stability; lawv cov khoom siv lub cev thiab tshuaj lom neeg hloov pauv tsawg heev nyob rau hauv qhov sib txawv ntawm qhov kub thiab txias, ua kom ruaj khov ntawm kev sib txuas lus kab noj hniav nyob rau hauv ntau qhov kub thiab txias. Tsis tas li ntawd, titanium alloys muaj qee yam hluav taws xob tiv thaiv hluav taws xob, pab ua kom tau raws li qhov xav tau ntawm ib puag ncig electromagnetic ntawm kev sib txuas lus kab noj hniav.

Poob- khib nyiab pov tseg yog ib txoj kev casting precision. Nws lub hauv paus ntsiab lus yog thawj zaug tsim cov qauv siv quav ciab nrog tib yam li cov kab noj hniav sib txuas lus. Cov qauv siv quav ciab muaj cov yas zoo, tso cai rau kev rov ua dua ntawm cov kab noj hniav txoj kab thiab cov ntsiab lus. Tom qab ntawd, cov qauv siv quav ciab tau sib sau ua ke rau hauv ib qho module, thiab ntau txheej ntawm cov khoom siv refractory yog coated rau ntawm qhov chaw module los tsim ib lub plhaub monolithic. Thaum lub sij hawm txheej txheej txheej, qhov loj me thiab cov ntsiab lus ntawm txhua txheej ntawm cov khoom siv refractory raug hloov kho raws li qhov xav tau sib txawv kom ntseeg tau tias lub plhaub lub zog thiab qhov tseeb. Tom ntej no, lub plhaub yog rhuab, ua rau cov qauv siv quav ciab kom yaj thiab ntws tawm, yog li tsim cov kab noj hniav hauv lub plhaub uas phim cov duab ntawm cov kab sib txuas lus. Thaum kawg, molten titanium alloy yog nchuav rau hauv kab noj hniav ntawm pwm los ntawm lub rooj vag. Tom qab cov titanium alloy txias thiab solidifies, cov pwm yog tawg kom tau qhov xav tau kev sib txuas lus kab noj hniav casting.

Poob-wafer casting tuaj yeem tsim kev sib txuas lus kab noj hniav nrog cov duab nyuaj. Kev sib txuas lus kab noj hniav feem ntau muaj ntau yam tsis sib xws, nyias- cov qauv phab ntsa, thiab cov kab hauv sab hauv, ua rau nws nyuaj rau kev ua tiav cov khoom tsim ntawm cov duab nyuaj uas siv cov txheej txheem machining. Poob-wafer casting, txawm li cas los xij, tuaj yeem rov ua cov duab zoo li no rau hauv cov casting los ntawm kev tsim cov qauv siv quav ciab. Ib txhij, poob-wafer casting ua kom qhov tseeb qhov tseeb thiab qhov zoo. Vim tias qhov tseeb qhov tseeb ntawm cov qauv siv quav ciab tuaj yeem tswj tau nyob rau hauv ntau qhov me me, thiab cov txheej txheem tsim pwm kuj ua kom muaj qhov ruaj khov, qhov kev sib txuas lus cam khwb cia muaj qhov raug siab. Tsis tas li ntawd, qhov zoo nkauj sab hauv ntawm cov pwm ua kom zoo ntawm qhov zoo ntawm cov casting, txo cov haujlwm ntawm kev ua haujlwm tom ntej. Tsis tas li ntawd, poob -wafer casting muaj kev ua haujlwm siab thiab ua kom yooj yim. Nws tuaj yeem tsim cov qauv siv quav ciab ntawm cov duab sib txawv thiab qhov ntau thiab tsawg raws li qhov xav tau sib txawv, ua kom haum rau ntau hom kev xav tau ntawm kev sib txuas lus kab noj hniav, thiab ua kom muaj ntau lawm.

1. Kev Ua Qauv Ua Qauv: Xaiv cov khoom siv quav ciab tsim nyog yog qhov tseem ceeb. Cov khoom siv siv quav ciab yuav tsum muaj qhov zoo fluidity, tsawg shrinkage, nruab nrab lub zog, thiab yooj yim demolding. High-cov pwm precision thiab cov txheej txheem txhaj tshuaj molding siab heev yuav tsum tau siv los xyuas kom meej qhov raug thiab qhov zoo ntawm cov qauv siv quav ciab. Nyob rau tib lub sijhawm, tus qauv siv quav ciab yuav tsum tau kuaj xyuas nruj kom tshem tawm qhov tsis xws luag thiab qhov sib txawv ntawm qhov sib txawv, kom ntseeg tau tias nws ua tau raws li cov qauv tsim.

2. Pwm Plhaub Manufacturing: Qhov zoo ntawm lub plhaub pwm ncaj qha cuam tshuam qhov zoo ntawm cov casting. Cov khoom siv refractory tsim nyog yuav tsum raug xaiv, thiab qhov loj me, muaj pes tsawg leeg, thiab kev faib ua feem ntawm cov khoom siv refractory yuav tsum tau txiav txim siab raws li cov yam ntxwv ntawm kev sib txuas lus kab noj hniav thiab kev xav tau casting. txheej txheej txheej kuj tseem ceeb heev; lub thickness ntawm txhua txheej txheej, ziab lub sij hawm, thiab tus naj npawb ntawm cov coatings yuav tsum tau ua tib zoo tswj los xyuas kom meej lub zog thiab precision ntawm pwm plhaub. Tsis tas li ntawd, cov txheej txheem tua hluav taws ntawm lub plhaub pwm kuj yuav tsum muaj kev tswj xyuas meej. Kev kub hnyiab thiab lub sijhawm cuam tshuam rau lub zog thiab permeability ntawm lub plhaub pwm, yog li cuam tshuam qhov zoo ntawm casting.

3. Titanium Alloy Melting thiab Casting: Melting ntawm titanium alloys yuav tsum tau ua nyob rau hauv lub tshuab nqus tsev los yog ib qho chaw tiv thaiv kom tsis txhob muaj kev cuam tshuam nrog oxygen, nitrogen, thiab lwm yam hauv huab cua, uas tuaj yeem cuam tshuam rau nws cov khoom. Kev tswj xyuas meej ntawm melting kub thiab lub sij hawm yog ib qho tseem ceeb los xyuas kom meej tag nrho melting thiab uniform muaj pes tsawg leeg. Thaum lub sij hawm casting, lub pouring ceev thiab kub yuav tsum tau ua tib zoo tswj kom tsis txhob muaj qhov tsis xws luag xws li filling tsis tiav los yog txias kaw. Lub rooj vag tsim nyog yuav tsum tau siv los xyuas kom meej tias molten titanium alloy smoothly puv cov kab noj hniav ntawm lub plhaub pwm.

4. Tshaj tawm- kev ua tiav: Tom qab casting, kev sib txuas lus kab noj hniav yuav tsum tau ua cov kauj ruam tom ntej. Ua ntej, lub plhaub pwm thiab risers raug tshem tawm siv cov txheej txheem los yog tshuaj. Tom qab ntawd, kev kho cua sov yog ua tiav, tswj cov cua sov thiab cua txias kom txhim kho microstructure thiab cov khoom ntawm titanium alloy, ua kom nws lub zog thiab tawv. Tom ntej no, kev kho deg xws li polishing thiab sandblasting yog siv los txhim kho qhov zoo thiab corrosion kuj ntawm casting. Thaum kawg, qhov kev sib txuas lus kab noj hniav tau raug soj ntsuam xyuas zoo, suav nrog kev ntsuas qhov tseeb, tsis yog -kev ntsuas kev puas tsuaj, thiab kev sim ua haujlwm, kom ntseeg tau tias cov khoom ua tau raws li cov qauv zoo.
