Lub luag haujlwm thiab cov kev xav tau ntawm cov hlau ua silicon nyob rau hauv txhuas ingot ntau lawm

Silicon hlau (metallurgical qib muaj silicon) feem ntau yog cov kev ua haujlwm ntawm almoying thiab kev ua tiav txoj haujlwm yog xav txog ntawm plaub yam hauv qab no:

{{01.} Txhim kho txhim kho cov khoom siv mecha tshuab: "txhim kho" ntawm lub zog thiab hardness

Silicon yog ib qho tseem ceeb tshaj plaws cov ntsiab lus hauv aluminium matoys rau cov khoom siv tsis yooj yim thaum muaj kev cuam tshuam nrog cov khoom siv tsis zoo Thaum cov ntsiab lus silicon nce los ntawm 1% rau 10%, nws lub zog tensile yuav nce ntau dua li 250mpa kom tau nce ntau dua li 250mpa kom tau nce ntxiv ntawm 100MPA, thiab lub zog hab) ntau dua li 250MPA, thiab cov log tsheb thiab lwm yam {8}

{{02.}}} txhim kho kev ua haujlwm sib nraus pleb

Nyob rau hauv kev tsim cov cam khwb cia ing ing ing muaj peev xwm txo cov xim ntshiab ntawm aluminium yog 660 qhov kev sib tw tsis yooj yim rau aluminium alloys kom sau cov khoom lag luam aluminium Casting thiab xuab zeb casting, txo cov khoom tsis zoo xws li 40% ntau dua li cov ntaub ntawv ntshiab (xws li cov khoom sib txuas lus zoo nkauj uas muaj 8%? Ntau tshaj 95% .

3.} kev ua haujlwm zoo: "Regulator" rau kev tawg tsis kam thiab txiav kev ua haujlwm

Qhov sib ntxiv ntawm cov thawv silicon tuaj yeem txhim kho kev ua haujlwm ntawm txhuas kev ua qoob loo, ncu kom muaj kev phom sij thaum muaj kev sib tsoo, ncab thiab lwm yam txheej txheem. hauv high-silicon alloy alloy kev cuam tshuam, silicon yog tusyees faib rau hauv cov khoom zoo, uas tuaj yeem txhim kho cov khoom siv ntawm cov khoom uas xav tau precision ua (xws li txhuas profiles rau aerospace rau aerospace) {}

4.}} txhim kho corrosion tsis kam: ib puag ncig hloov kho "tiv thaiv tus neeg sawv cev"

Cov theem sib xyaw tsim los ntawm silicon thiab txhuas muaj cov tshuaj tsis huv ntawm txhuas Lub neej kev pabcuam ntev dua hauv phab ntsa engineering, cov tshuaj tsuag sab nrauv, thiab siv cov tshuaj txhuam rau lub sijhawm, thiab cov khoom siv ntshiab txhuas kom ntau dua 500 teev {7} {7}.

YUAV TSUM TAU TXAIS RAU SILICO HLAU: Metallurgical QibSilicon 441/ Silicon 553yog lub ntsiab

Cov khoom lag luam silicon siv hauv txhuas kev siv hlau ntau heev cuam tshuam nrog 0.4% thiab ntau dua lossis sib npaug lossis sib npaug lossis sib npaug 0.5%, ca tsawg dua los yog sib npaug rau 0.3%):

 High-end casing txhuas kev noj haus (xws li tsheb cav lub tog raj kheej (xws li. Cov pa roj ntsha tau (xws li tsis muaj 441

 Dog dig Casting thiab deformation Txhuas ingots tuaj yeem siv 553 hlau silicon kom txo tus nqi raw li cas thaum muaj siab-silicon aluminium ingots, 441 lossis3303 silicon hlauNrog cov kev coj dawb siab dua yuav tsum tau siv kom tsis txhob cuam tshuam kev cuam tshuam rau thermal conductivity thiab hnav tsis kam .

Ntxiv rau cov ntsiab lus, lub curity thiab impred tswj ntawm silicon hlau yog qhov tseem ceeb heev rau qhov zoo ntawm txhuas ingots:

 Tsawg txhuas thiab cov hlau tsawg: Aluminium thiab hlau impurities nyob rau hauv cov kab ke sib tsoo (ua rau muaj kev sib tsoo ​

 Tsawg calcium thiab tsawg phosphorus: calcium yuav txo cov dej ntawm aluminium hlau yuav tsum los tswj cov calcium tsawg dua los yog sib npaug ntawm 0} 3% thiab phosphorus tsawg dua los yog sib npaug rau 0.02%. ​

 Uniform loj: qhov loj me ntawmSilicon Hlau (feem ntau 10-100 hli)Yuav tsum muaj cov ris tsho kom tsis txhob ua tsis tiav ntawm cov kab ke loj ntawm silicon thaum smelting, lossis poob los ntawm ya zoo hmoov .

Silicon metal plays multiple roles in alloying enhancement, casting optimization, processing improvement and corrosion resistance improvement in aluminum ingot production. Its content and purity directly determine the performance and application scenarios of aluminum ingots. From 5%-12% of cast aluminum ingots to 1%-5% of deformed aluminum ingots, and then to 10% {{{{}}% ntawm tshwj xeeb high-silicon cov ntsiab lus yog qhov kev siv cov kab ke sib txawv yog cov tseem ceeb tuaj yeem yog tus neeg muaj peev xwm kev tsim cov tshuaj txhuas cov .
