Qhov zoo ntawm aluminium alloy tuag castings feem ntau qhia txog cov txheej txheem ntawm aluminium alloy tuag casting manufacturers thiab kuj yog lub hauv paus rau ciaj sia taus ntawm txhuas alloy tuag casting manufacturers. Yog li ntawd, kev txhim kho qib zoo ntawm aluminium alloy tuag-casting qhov chaw tau dhau los ua qhov tseem ceeb rau aluminium alloy die-casting manufacturers los sib tw nrog lwm cov tuam ntxhab. Ntawm ntau yam uas cuam tshuam rau qhov zoo ntawm aluminium alloy tuag castings, hydrogen yog qhov txaus ntshai zais uas tsis tuaj yeem tsis quav ntsej. Nws cuam tshuam rau qhov zoo ntawm aluminium alloy tuag castings thiab ua rau mob taub hau rau ntau aluminium alloy tuag casting manufacturers.
Tsuas yog los ntawm kev tshem tawm cov "villain" hydrogen nyob rau hauv aluminium alloy yaj tau qhov zoo ntawm aluminium alloy tuag castings yuav txhim kho mus rau qib tom ntej. Yog li, ua li cas hydrogen hauv aluminium alloy yaj cuam tshuam qhov zoo ntawm aluminium alloy tuag castings?
- Hydrogen yuav yaj nyob rau hauv aluminium alloy yaj thiab maj mam precipitate thaum lub sij hawm solidification txheej txheem ntawm txhuas alloy tuag-casting los tsim pores. Lub xub ntiag ntawm pores yuav tsis tsuas yog txo lub zog thiab sealing kev ua tau zoo ntawm lub casting tab sis kuj yuav ua rau tawg ntawm lub casting. Porosity muaj kev cuam tshuam loj rau qhov zoo thiab kev ua tau zoo ntawm cov castings, tshwj xeeb tshaj yog thaum nws raug kev kub ntxhov los yog kev ntxhov siab, thiab tuaj yeem ua tau yooj yim los ua qhov tsis muaj zog rau lub casting kom tawg.
- Qhov thib ob, qhov nce hauv cov ntsiab lus hydrogen hauv aluminium alloy yaj kuj yuav ua rau cov casting deform. Thaum cov ntsiab lus hydrogen siab, cov npuas thiab qhov pores tsim nyob rau hauv cov kua aluminium alloy yuav maj mam nthuav thaum lub sij hawm solidification txheej txheem, ua rau muaj kev nyuaj siab concentration thiab lub zos deformation nyob rau hauv lub tuag casting. Qhov no yuav tsis tsuas yog ua rau qhov tsis raug ntawm qhov ntev ntawm cov castings tab sis kuj yuav ua rau muaj kev cuam tshuam ntawm cov duab ntawm cov castings, cuam tshuam rau kev sib dhos thiab siv cov khoom.
- Tsis tas li ntawd, qhov nce hauv hydrogen cov ntsiab lus hauv cov yaj yuav ua rau muaj kev cuam tshuam rau qhov zoo ntawm qhov casting. Cov ntsiab lus hydrogen siab tuaj yeem ua rau lub qhov hws thiab npuas tshwm rau ntawm qhov chaw casting, txo qhov ua tiav ntawm qhov chaw thiab zoo li zoo. Hauv qee qhov kev lag luam uas muaj cov kev xav tau siab rau cov tsos, xws li tsheb, khoom siv hluav taws xob, thiab lwm yam kev lag luam, qhov zoo ntawm castings yog ncaj qha ntsig txog kev lag luam kev sib tw thiab cov neeg siv khoom ntawm cov khoom. Yog li ntawd, cov tuam ntxhab ntawm cov khoom zoo li no muaj kev txwv nruj dua rau kev tshem tawm hydrogen.
- Mindwell Aluminium Tuag Casting Lub Tuam Txhab tau sau cov kev paub nplua nuj thiab thev naus laus zis los daws cov teeb meem no. Ua ntej ntawm tag nrho cov, peb pib nrog kev xaiv ntawm raw cov ntaub ntawv thiab tsuas yog siv refined aluminium alloy ingots uas tsis muaj hydrogen cov ntsiab lus, txo cov kev cuam tshuam ntawm hydrogen ntawm cov khoom zoo los ntawm qhov chaw. Thaum lub sij hawm tsim cov txheej txheem, peb ntxiv dag zog rau smelting kev kho mob ntawm aluminium alloy yaj, thiab los ntawm kev tswj qhov kub thiab txias thiab cua thaum lub sij hawm melting txheej txheem, peb zoo txo qhov nqus thiab cov ntsiab lus ntawm hydrogen.
- Tsis tas li ntawd, peb xyuam xim rau cov txheej txheem tswj kev tshem tawm roj. Los ntawm rationally kho qhov tuag-casting tsis, xws li nce lub siab thiab ncua lub sij hawm txhaj tshuaj, peb muaj peev xwm zoo txhawb lub tso tawm ntawm hydrogen los ntawm molten aluminium alloy thiab txo qhov cuam tshuam ntawm hydrogen ntawm qhov zoo ntawm cov castings.
Ntxiv nrog rau cov txheej txheem kev txhim kho, peb kuj xyuas kom meej tias qhov kev tshawb fawb thiab tsim nyog vents tau teeb tsa nyob rau hauv cov theem pib ntawm pwm tsim los ntawm optimizing cov cuab yeej thiab pwm tsim kom tsis txhob tawm ntau hydrogen roj nyob rau hauv lub casting los ua kab noj hniav. Peb kuj tau tsim kom muaj kev tswj xyuas nruj nruj, siv cov txheej txheem tshuaj xyuas thawj zaug, tshawb pom cov teeb meem raws sij hawm, thiab hloov kho thiab kho cov txheej txheem tsis zoo los xyuas kom meej tias cov khoom zoo raws li qhov yuav tsum tau ua.
Qhov tseem ceeb ntawm kev tshem tawm hydrogen thaum lub sij hawm txhuas alloy tuag casting tsis tuaj yeem tsis quav ntsej. Peb nquag txhim kho peb cov txheej txheem kev tshaj lij thiab cov txheej txheem kev tswj hwm, tswj tau zoo thiab txo cov ntsiab lus hydrogen, txhim kho cov khoom zoo thiab kev ua tau zoo, thiab muab cov neeg siv khoom zoo castings. Raws li ib tug tswv cuab ntawm aluminium alloy tuag-casting kev lag luam, peb paub tob txog qhov tseem ceeb ntawm kev tshem tawm hydrogen rau cov khoom zoo, ntxiv dag zog rau kev tshawb fawb thiab kev tsim kho tshiab, txhim kho casting zoo, thiab pab txhawb rau kev txhim kho tag nrho kev lag luam.
