Muab lub hau tso rau ntawm qhov chaw tsim khoom thiab cia nws sov so
- Cia lub qhov cub kom sov li 10 feeb ua ntej tso aluminium hauv nws.
- Qhov kub hauv qhov chaw tsim khoom yuav tsum siab tshaj 1220 degrees Fahrenheit (660 degrees Celsius).
- Thaum lub crucible yog ci txiv kab ntxwv, lub foundry yog kub txaus kom yaj aluminium .
Ua raws li qhov no, koj yuav ua li cas ntxuav cov molten aluminium?
Txoj kev siv dav tshaj plaws rau purify aluminium yog kev txhaj tshuaj ntawm cov pa roj lossis roj sib xyaw uas muaj nitrogen, argon, thiab chlorine. Cov txheej txheem txhaj tshuaj rau hauv lub molten aluminium suav nrog cov txheej txheem lance, uas tsis yog qhov tseem ceeb hauv kev lag luam raws li nws tau siv los ua, txheej txheem ntsaws ntsaws, thiab txheej txheem impeller rotor.
Ib tug kuj nug, puas yog txhuas lo rau molten txhuas? aluminium muaj ib tug tshwj xeeb resilient thiab inert nto oxide txheej thiaj li molten aluminium yuav tsis cia li stick mus rau saum npoo ntawm cov khoom aluminium . Aluminium anneals raws li qhov kub thiab txias thiab yog tias qhov uas twb muaj lawm nce mus txog qhov kub ntawm nws yuav yuav tsis muaj zog heev thiab muaj lub caij nyoog zoo uas nws yuav yuam kev.
Yog li ntawd, puas molten aluminium lo rau hlau?
Teb: Aluminium thiab hlau yog cov ntaub ntawv zoo nkauj incompatible, lawv tsis tsim ib qho alloy kuv tsis xav, yog li nws tsis zoo li lawv yuav. stick . Tsis tas li, ob leeg hlau yuav tau txais ib txheej oxide rau ntawm qhov chaw uas yuav tsum ua kom lawv sib cais. Cov aluminium yuav shrink ntau tshaj qhov hlau hauv qhov txias thiab yuav tuav tus pas nrig nruj heev.
Txoj kev yooj yim tshaj plaws rau yaj hlau hauv tsev yog dab tsi?
Yog koj xav tau yaj hlau , koj yuav tsum nrhiav txoj hauv kev los thov kom muaj cua sov ntau rau nws. Qhov no tuaj yeem ua tiav nrog lub hauv paus lossis lub teeb. Nrog ib tug foundry, lub hlau tuaj yeem yog yaj rau hauv cov kua uas koj tuaj yeem ua pwm rau hauv txhua yam uas koj nyiam. Nrog lub teeb ci, koj tuaj yeem ua tau yaj dhau hlau thiab txiav nws mus rau hauv ntau yam duab.

Yuav ua li cas ua aluminium acetate?
Sib tov: 1 feem calcium acetate los yog (sodiumacetate) nrog 1 feem Alum (potassium aluminiumsulfate). Ua kom txaus aluminium acetate rau mordant1 kilo ntawm cov ntaub, muab 150g calcium acetate nrog 150 gpotassium aluminium sulfate hauv 3 liv dej kub
Puas yog aluminium foil tiag tiag aluminium?
Aluminium ntawv ci yog tsim los ntawm ib qho txhuas alloy uas muaj nyob nruab nrab ntawm 92 thiab 99 feem pua ntawm txhuas. Feem ntau ntawm 0.00017 thiab 0.0059 ntiv tes tuab, ntawv ci yog tsim los ntawm ntau qhov dav thiab muaj zog rau ntau pua daim ntawv thov
Qhov feem pua ntawm Aluminium nyob rau hauv Aluminium oxide yog dab tsi?
Qhov feem pua ntawm txhuas hauv aluminium oxide yog 52.93 feem pua
Qhov twg zoo dua aluminium lossis cam khwb cia aluminium patio rooj tog?
Hnyav dua li extruded aluminium thiab ob qho tib si sib zog thiab ruaj khov dua li cov hlau wrought, cam khwb cia aluminium patio rooj tog yog thawj qhov kev xaiv rau feem ntau. Muab khoom nrog cov khoom zoo, ntev-ntev zoo hmoov coated tiav, cam khwb cia aluminium rooj tog paub tias yuav kav ntev li ntawm peb caug xyoo nrog kev saib xyuas me ntsis
Dab tsi yog molten aluminium siv rau?
Casting yog thawj thiab feem ntau siv txoj hauv kev los ua txhuas rau hauv cov khoom. Kev txhim kho txuj ci tau ua tiav, tab sis lub hauv paus ntsiab lus tseem zoo ib yam: Molten aluminium yog nchuav rau hauv pwm kom duplicate tus qauv xav tau. Peb txoj kev tseem ceeb tshaj plaws yog tuag casting, pwm mus tas li thiab xuab zeb casting
