Ob qho yooj yim cov duab ntawm hmoov metallurgy

Ob qho yooj yim cov duab ntawmhmoov metallurgyyog qhov peb xav qhia rau koj. Cia peb ua raws li zhongwei precision knitting.

Hmoov metallurgy yog qhov tseem ceeb ntawm qhov loj me thiab cov duab ntawm cov hmoov:

Particle loj: nws cuam tshuam rau kev ua thiab kev tsim cov hmoov, lub shrinkage thaum sintering thiab qhov kawg kev ua tau zoo ntawm cov khoom. Kev ua tau zoo ntawm qee cov hmoov metallurgy cov khoom lag luam yuav luag ncaj qha ntsig txog qhov loj me me. Piv txwv li, qhov tseeb ntawm cov khoom lim lim tuaj yeem tau txais kev pom zoo los ntawm kev faib qhov nruab nrab ntawm qhov loj me ntawm cov hmoov qub los ntawm 10; Cov khoom ntawm cov khoom cemented carbide yog ze ze rau cov nplej loj ntawm wc theem. Yuav kom tau txais cov cemented carbide nrog finer grain loj, nws tsuas yog siv tau wc raw cov ntaub ntawv nrog finer grain loj. Cov hmoov siv hauv kev xyaum ntau lawm muaj qhov loj me ntawm ntau pua nanometers mus rau pua pua microns. Qhov me me qhov me me, qhov ua haujlwm ntau dua, thiab qhov yooj yim ntawm qhov chaw yog oxidize thiab nqus dej. Thaum nws yog me me li pua pua nanometers, kev cia thiab kev thauj mus los ntawm cov hmoov tsis yooj yim, thiab thaum nws tsawg npaum li ib qib, cov nyhuv quantum pib siv, thiab nws lub cev lub cev yuav hloov tau zoo heev, piv txwv li. , ferromagnetic hmoov yuav dhau los ua superparamagnetic hmoov, thiab lub melting point kuj yuav txo nrog qhov txo ntawm particle loj.

Cov hmoov zoo ntawm cov hmoov: nws nyob ntawm txoj kev npaj hmoov, xws li cov hmoov tau los ntawm electrolysis, thiab cov khoom yog dendritic; Cov hmoov hlau uas tau los ntawm txoj kev txo qis yog spongy thiab flaky; Cov pa roj atomization txoj kev yog cov hmoov kheej kheej kheej kheej. Tsis tas li ntawd, qee cov hmoov yog nyob rau hauv cov duab ntawm lub qe, disc, koob thiab dos. Cov duab ntawm cov hmoov yuav cuam tshuam qhov fluidity thiab bulk ntom ntawm hmoov. Vim lub tshuab meshing ntawm cov khoom, lub zog ntawm cov hmoov tsis sib xws yog qhov loj, tshwj xeeb tshaj yog lub zog ntawm dendritic hmoov compacts. Tab sis rau cov ntaub ntawv ntxeem tau, spherical hmoov yog qhov zoo tshaj plaws.

Cov cuab yeej siv tshuab Cov cuab yeej cuab tam ntawm cov hmoov yog cov cuab yeej thev naus laus zis ntawm cov hmoov, uas yog ib qho tseem ceeb thev naus laus zis tsis zoo hauv cov txheej txheem ua hmoov metallurgy. Qhov ntom ntom ntawm cov hmoov yog lub hauv paus rau kev hnyav los ntawm ntim txoj kev thaum lub sij hawm compaction; Lub fluidity ntawm cov hmoov txiav txim siab filling ceev ntawm cov hmoov mus rau qhov tuag thiab lub peev xwm ntau lawm ntawm cov xovxwm; Lub compressibility ntawm cov hmoov txiav txim siab qhov nyuaj ntawm cov txheej txheem nias thiab qib ntawm kev thov siab; Lub formability ntawm cov hmoov txiav txim siab lub zog ntawm lub billet.

Cov khoom siv tshuaj lom neeg feem ntau yog nyob ntawm cov tshuaj purity ntawm raw cov ntaub ntawv thiab txoj kev milling. Cov ntsiab lus ntawm cov pa oxygen ntau dua yuav txo qhov kev ua tau zoo, lub zog compact thiab cov khoom siv ntawm cov khoom siv sintered, yog li feem ntau ntawm cov txheej txheem ntawm cov hmoov metallurgy muaj qee cov kev cai. Piv txwv li, cov pa oxygen cov ntsiab lus ntawm cov hmoov yog 0.2 feem pua ​​~ 1.5 feem pua, uas yog sib npaug rau cov ntsiab lus oxide ntawm 1 feem pua ​​~ 10 feem pua.

Txhawm rau ua kom tiav, ob daim duab yooj yim tshaj plaws ntawm cov hmoov metallurgy tau qhia rau koj. Kuv vam tias tsab xov xwm no tuaj yeem pab koj. Yog tias koj xav paub ntau ntxiv, thov tuaj rau Zhenglang kom nkag siab, thiab peb yuav muaj cov kws tshaj lij los teb rau koj.

Qinhuangdao Zhongwei Precision Machinery Co., Ltd. yog cov nroj tsuag tshuaj niaj hnub nrog ua tiav hmoov metallurgy tsim muaj peev xwm, tshwj xeeb hauv kev tsim cov planetary iav reducer, nws pib qhov chaw, ua haujlwm siab hmoov metallurgy qhov chaw thiab precision hardware qhov chaw, thiab lwm yam. dav siv hauv tsheb, kev sib txuas lus, khoom siv hauv chaw ua haujlwm, khoom siv hauv tsev, xauv thiab lwm yam lag luam. Muab cov txheej txheem sib kis tsim kev daws teeb meem rau cov neeg siv khoom hauv ntau qhov kev lag luam.
