Gas atomization yog ib txoj hauv kev tseem ceeb rau kev tsim cov hmoov hlau thiab hlau alloy.

Advanced hmoov npaj tshuab yog lub hauv paus ntawm niaj hnub hmoov metallurgy thiab khoom industrialization. Nws yog cov cuab yeej tsim khoom siab tshaj plaws uas ua ke nrog kev npaj cov khoom siv thiab ua ib feem, muab kev txuag hluav taws xob, kev txuag cov khoom siv, kev ua haujlwm siab, kev ua haujlwm zoo, thiab muaj kuab paug tsawg. Nws yog qhov tsim nyog rau kev tsim khoom loj thiab ua lub luag haujlwm tsis tuaj yeem hloov pauv hauv cov ntaub ntawv thiab cov khoom tsim kev lag luam, dhau los ua ib qho tseem ceeb ntawm cov khoom siv science thiab kev tshawb fawb engineering. Hlau hmoov Atomization khoom

Cov hmoov uas tsim los ntawm kev siv atomization suav txog 80% ntawm lub ntiaj teb cov hmoov tag nrho, nrog rau cov roj atomization accounting rau 30% -50%. Qhov no txhais tau hais tias yuav luag ib nrab ntawm tag nrho cov hmoov yog tsim los ntawm kev siv roj atomization tshuab. Cov hmoov uas ua los ntawm cov txheej txheem atomization nthuav tawm qhov zoo tshaj plaws, qhov loj me (hmoov txoj kab uas hla), particle loj tis concentration, metallization thiab ntom, thiab nto zoo piv rau cov tshuaj siv tshuaj hmoov.

Cov thev naus laus zis tseem ceeb rau kev nkag siab thiab tswj kev sib txawv ntawm Flow Field Evolution

Atomization hmoov npaj tshuab yog dav siv nyob rau hauv domestic additive manufacturing, sib nqus cov ntaub ntawv, thiab lwm yam manufacturing industries, thiab kuj yog ib qho tseem ceeb txhais tau tias ntawm cov khoom zoo upgrading thiab tshiab khoom tsim.

Gas atomization, ua ib txoj hauv kev tseem ceeb rau kev tsim cov hmoov hlau thiab cov hmoov hlau, ua haujlwm los ntawm kev siv lub siab - roj ntws nrawm los ua kom cov kua hlau ntws mus rau hauv cov tee me me, uas tom qab ntawd khov rau hauv cov hmoov. Vim qhov zoo ntawm purity siab, tsis tshua muaj oxygen cov ntsiab lus, tswj tau qhov loj me, tsis tshua muaj nqi tsim khoom, thiab siab sphericity, nws tau dhau los ua kev txhim kho loj rau kev npaj siab - kev ua tau zoo thiab cov hmoov hlau tshwj xeeb.

Tam sim no, ntau tus neeg sawv cev roj atomization hmoov cov thev naus laus zis muaj xws li: laminar flow atomization, ultrasonic nruj-coupled atomization, thiab roj kub atomization.

Laminar flow atomization technology sawv cev rau kev txhim kho tseem ceeb ntawm cov pa nozzles. Cov nozzles txhim kho muaj kev ua haujlwm siab atomization, nqaim particle loj faib, ceev ceev txias, tsis tshua muaj roj noj, thiab cov txiaj ntsig tseem ceeb ntawm kev lag luam, thiab tsim nyog rau kev tsim cov hmoov hlau feem ntau.

Ultrasonic nruj-coupled atomization tshuab optimizes cov qauv ntawm lub nruj-coupled annular slit nozzle, tso cai rau lub qhov hluav taws xob tshaj tawm ntawm cov roj ntws mus tshaj lub ceev ntawm lub suab thiab ua rau cov huab hwm coj txaus tus nqi ntawm cov hlau. Thaum atomizing siab nto zog hlau xws li stainless hlau, qhov nruab nrab hmoov particle loj tuaj yeem ncav cuag li 20 μm, thiab tus qauv sib txawv ntawm cov hmoov tuaj yeem txo mus rau 1.5 μm. Qhov no ua kom zoo dua qhov txias ntawm cov hmoov, ua kom cov khoom ua kom txias txias los yog amorphous hmoov. Nws muaj qhov tseem ceeb hauv kev lag luam thiab tuaj yeem siv dav rau kev tsim cov hlau tsis zoo, ferroalloys, npib tsib xee alloys, tooj liab alloys, cov khoom sib nqus, cov khoom siv hydrogen, thiab lwm yam hmoov hlau.

Piv nrog rau cov thev naus laus zis atomization ib txwm muaj, cov roj kub atomization txhim kho atomization efficiency, txo cov roj noj, thiab yooj yim siv rau cov khoom siv atomization, ua rau nws muaj kev vam meej technology. Txawm li cas los xij, cov tshuab hluav taws xob kub atomization yog txwv los ntawm cov cua kub cua sov thiab cov nozzles, thiab tsuas yog ob peb lub koom haum tshawb fawb tau tshawb fawb txog nws.

Muaj feem xyuam thoob plaws ntau lub teb, accelerating txoj kev loj hlob ntawm industrial saw.

Gas atomization hmoov cov cuab yeej tsim khoom tsim nyog rau kev tsim cov hmoov (los yog granular) cov ntaub ntawv los ntawm cov hlau, ceramics, thiab lwm yam uas tsis yog -hlau los yog hlau alloys nyob rau hauv kev tiv thaiv roj los yog zoo tib yam atmospheric tej yam kev mob (siv zoo tib yam melting los yog nqus melting). Nqus melting gas atomization thiab tsis yog -nqus melting gas atomization txoj kev tuaj yeem siv nyob ntawm cov txheej txheem tsim cov hmoov.

Cov hmoov uas tau txais los ntawm cov roj atomization hmoov npaj rau kev tsim cov khoom siv raw rau cov hluav taws xob sib txuas muaj qhov zoo hauv qab no: cov hmoov muaj qhov me me thiab cov ntsiab lus me me, nrog rau qhov zoo txog li 10 μm (1250 mesh), uas yuav pab txhim kho cov khoom siv; cov hmoov metallized thiab kheej kheej muaj cov dej ntws zoo, thiab cov ciam teb ntuj tuaj yeem cuam tshuam cov qoob loo loj hlob thaum tsim khoom thiab siv cov khoom siv; cov hmoov uas tsim los ntawm electromagnetic stirring los ntawm induction rauv melting muaj ib tug uniform alloy muaj pes tsawg leeg thiab siab ceev, uas yuav xyuas kom meej qhov zoo ntawm cov khoom; cov metallized hais tsis yooj yim rau agglomerate thiab lo ua ke, uas ua rau tsis pom kev poob.
