Hlau hlau peev casting yog cov txheej txheem tsim tshwj xeeb uas sib txuas cov khoom siv zoo tshaj plaws ntawm cov hlau nodular-xws li lub zog tensile siab thiab kev cuam tshuam tsis kam-nrog rau qhov kev txiav txim siab qhov ntev thiab cov peev txheej geometric ntawm txoj kev ploj-wax casting. Tsis zoo li cov xuab zeb casting ib txwm, uas feem ntau yuav tsum tau siv dav hauv kev ua haujlwm thib ob, peev casting tsim cov khoom nyob ze-net-puab cov khoom nrog superior nto tiav thiab nruj dua kam rau ua. Qhov kev sib xyaw ua ke no yog qhov tseem ceeb rau kev lag luam uas xav tau lub luag haujlwm tseem ceeb hauv qhov chaw uas yuav tsum tiv taus siab, hnav, thiab cov khoom hnyav, xws li cov tshuab hydraulic, cov khoom siv roj thiab roj, thiab cov tsheb loj engineering.
Dab tsi yog Ductile Iron Investment Casting?
Ductile hlau, tseem hu ua nodular hlau los yog spheroidal graphite hlau, yog tus cwj pwm los ntawm kheej kheej graphite inclusions nyob rau hauv nws cov microstructure. Cov qauv no muab ntau dua ductility thiab toughness piv rau grey cam khwb cia hlau. Thaum tsim los ntawm kev nqis peev casting (tseem hu ua precision casting), cov khoom siv tau txais txiaj ntsig los ntawm cov qauv ua kom zoo dua qub vim tias cov cua txias nrawm dua cuam tshuam nrog cov plhaub plhaub pwm.
Cov txheej txheem suav nrog tsim cov qauv siv quav ciab ntawm qhov xav tau, sib sau ua ke rau hauv tsob ntoo, dipping hauv ceramic slurry, thiab stuccoing nrog cov ntaub ntawv refractory. Tom qab lub plhaub hardens, cov wax melted tawm ("poob"), thiab molten ductile hlau yog poured rau hauv kab noj hniav. Qhov tshwm sim yog ib feem uas muaj:
- High Strength-rau-Weight Ratio: Qhov zoo tshaj plaws rau kev txav ntawm cov tsheb hauv engineering qhov twg qhov kev txo qis yog qhov tseem ceeb yam tsis muaj kev cuam tshuam cov qauv kev ncaj ncees.
- Complex Geometry: Muaj peev xwm nrum intricate intricate passages, nyias phab ntsa, thiab undercuts uas yog tsis yooj yim sua los yog txwv tsis pub kim rau tshuab los ntawm cov khoom Tshuag.
- Machinability zoo heev: Txawm hais tias nws lub zog, cov hlau nplaum tseem yog ib qho yooj yim rau tshuab rau kev ua tiav tiav.
- Kev vibration Damping: Lub peev xwm zoo tshaj plaws los nqus cov kev vibrations, ua rau nws zoo meej rau cov twj tso kua mis thiab cov khoom siv cav.
Kev tsim khoom: Step-by-Step
Kev nkag siab txog kev ua haujlwm ntau lawm yog qhov tseem ceeb rau cov kws tsim khoom thiab cov kws tshaj lij kev muag khoom soj ntsuam cov neeg xa khoom. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., kev tsim cov khoom siv hlau ua lag luam ua raws li kev nruj, ISO-raws li kev cai tsim los xyuas kom meej metallurgical sib xws thiab qhov raug.
1. Cov qauv tsim thiab sib dhos
Cov txheej txheem pib nrog kev txhaj tshuaj siv quav ciab rau hauv txhuas pwm los tsim cov qauv zoo. Cov qauv no yog tom qab sib sau ua ke rau hauv nruab nrab cov quav ciab sprue los ua "ntoo." Cov theem no yog qhov tseem ceeb rau kev txiav txim siab qhov tseeb qhov tseeb ntawm qhov kawg. Advanced CAD/CAM software yog siv los ua kom zoo dua qhov rooj kaw lus, ua kom cov hlau ntws zoo thiab txo qis qis.
2. Ceramic Plhaub Tsev
Lub wax sib dhos yog dipped rau hauv silica-based ceramic slurry thiab ces coated nrog zoo refractory xuab zeb. Cov txheej txheem dipping thiab stuccoing no yog rov ua ntau zaus los tsim lub plhaub ntawm cov tuab txaus thiab lub zog. Txhua txheej yuav tsum tau qhuav kom huv si kom tsis txhob delamination lossis tawg thaum lub sijhawm cua sov tom ntej.
3. Dewaxing thiab tua
Cov ntoo coated yog muab tso rau hauv autoclaves los yog ncu ncu kom yaj tawm cov quav ciab, tawm hauv qhov hollow ceramic pwm. Tom qab ntawd cov plhaub tau raug rho tawm haujlwm ntawm qhov kub siab (feem ntau tshaj 1000 ° C) kom tshem tawm cov khoom seem thiab cov av noo, thaum tib lub sijhawm ntxiv dag zog rau cov qauv ceramic rau hlau nchuav.
4. Melting thiab Pouring
Cov ntaub ntawv raw, suav nrog cov ntawv pov thawj npua hlau, steel seem, thiab ferroalloys, yog melted nyob rau hauv induction furnaces. Kev tswj nruj nruj ntawm cov tshuaj muaj pes tsawg leeg yog tswj xyuas kom muaj cov nodular graphite. Spheroidizing cov neeg ua haujlwm (xws li magnesium lossis cov ntsiab lus tsis tshua muaj hauv ntiaj teb) tau ntxiv los kho cov hlau molten. Cov hlau ua kua yog tom qab ntawd nchuav rau hauv cov khoom siv ua ntej rhuab hauv cov khoom siv tshuaj tiv thaiv kom tsis txhob muaj oxidation thiab ua kom tiav tiav.
5. Cua txias, Knockout, thiab txiav
Tom qab solidification, lub plhaub ceramic yog tawg lawm (knockout), thiab tus neeg castings raug txiav los ntawm lub rooj vag system. Kev txhaj tshuaj blasting yog ua los ntxuav qhov chaw thiab tshem tawm cov khoom siv refractory seem.
6. Kev kho cua sov thiab ua kom tiav
Nyob ntawm daim ntawv thov yuav tsum tau, cov khoom yuav raug kho cov txheej txheem kub xws li annealing, normalizing, lossis quenching thiab tempering kom ua tiav cov khoom siv kho tshuab. Thaum kawg, CNC machining yog ua kom tau raws li cov kev cai nruj rau cov kev sib tshuam tseem ceeb.
