Cov cuab yeej no tso cai rau nws los ua molded lossis khoov yooj yim yam tsis muaj kev tawg, uas yog qhov zoo heev rau cov tuam ntxhab nrog cov duab tshwj xeeb thiab tsim.
Manufacturing Takeaways
Vim nws cov khoom tshwj xeeb, daim txhuam cev hlau hmoov tuaj yeem hloov kho ib qho kev lag luam ntawm kev lag luam. Nws yog ntau yam thiab zoo tagnrho rau kev ua cov hlau, thiab lwm yam khoom siv hlau. Nws kuj tseem muaj txiaj ntsig zoo hauv kev tsim khoom ntawm lwm cov khoom siv tseem ceeb thiab kev tsim khoom.
Daim txhuam cev hlau hmoov yog ib qho kev nthuav dav siv hauv 3D luam ntawv. 3D luam ntawv yog ib lub tshuab uas ua rau tib neeg tsim cov qauv peb sab los ntawm kev ntxiv cov ntaub ntawv los ntawm txheej. Nws yog lub teeb yuag thiab kuj yog txoj hauv kev los coj cov duab, uas ua rau nws zoo meej hauv hom luam ntawv no. Qhov no qhia tias yav tom ntej, daim txhuam cev hlau hmoov txheej tuaj yeem hloov kho ntau lawm thiab tsim cov khoom lag luam uas hu rau lawv tso cai rau ntau yam kev xav muaj tswv yim nrog rau kev ua tau zoo thoob plaws hauv kev tsim khoom.
Daim txhuam cev Iron Powder ua li cas?
Cov txheej txheem ntawm kev tsim cov khoom zoo zoo sponge hlau hmoov tsis yooj yim heev, thiab muaj ntau lwm yam txheej txheem. Ua ntej ntawm tag nrho cov neeg ua hauj lwm mus rau lub ntiaj teb thiab khawb tawm hlau ore los ntawm hauv qab no. Cov hlau ore no ces tsiv mus rau lub Hoobkas kom ua tiav rau hauv daim txhuam cev hmoov hlau.
Tom qab cov hlau ore tawm hauv av, nws tuaj yeem xa mus rau peb cov neeg siv khoom hauv ob qhov sib txawv. Cov khoom me me no ces ua ke nrog lwm cov ntaub ntawv los ua ib qho kev sib xyaw uas tuaj yeem siv rau hauv qhov cub sintering. Lub cub tawg tau pib coj mus rau qhov kub siab uas cov hlau ore pib tawg mus rau hauv daim txhuam cev zoo li lub xeev ruaj khov.
Ntawm no, yuav ua li cas sponge hlau hmoov ua teeb meem. Daim txhuam cev hlau hmoov yuav tsis muaj zog lossis oxidant-resistant yog tias muaj qee qhov impurities hauv kev tsim khoom. Qhov no ua rau nws yog li txhua kauj ruam ntawm cov txheej txheem yuav tsum tau ua kom zoo kawg nkaus kom ua tau zoo heev.
Txhim kho kev ua tau zoo los ntawm kev txo qis hlau
Daim txhuam cev hlau puff yog tsawg heev thiab ncaj qha txo cov hlau (DRI) hom sponge buffer hmoov yog qhov zoo dua. Cov txheej txheem tshwj xeeb yog ua kom tau txais cov khoom zoo dua qub. Qhov no ua rau cov hlau txo qis kuj muaj txiaj ntsig zoo rau kev ntxiv dag zog thiab kev pab lub neej ntev.
Kev txo cov hlau ncaj qha yog tsim los ntawm kev tshem tawm cov pa oxygen los ntawm tus qauv sponge hlau hmoov. Qhov no ua tiav yog ua kom cov khoom kawg txawm tias muaj zog dua thiab muaj zog dua li nws tau pib nrog. Ntxiv mus, lub melting point ntawm ncaj qha txo hlau yog siab tshaj li ib txwm sponge hlau hmoov. Yog li qib no yog tsim nyog rau kev siv lub luag haujlwm hnyav thiab cov khoom xav tau kom muaj sia nyob ob lub zeb nplai tshem tawm thiab huab cua.
Nyob rau hauv cov ntsiab lus, cov zoo sponge hlau hmoov thiab ncaj qha txo tag nrho cam khwb cia. Los ntawm lub lair ntawm lub tsheb tsim mus rau cov dav hlau los yog cov tsev loj. Nrog rau kev txhim kho thev naus laus zis, muaj qhov ua tau uas peb yuav tsim kho tshiab siv rau cov khoom siv zoo kawg no.
