Qhov cuam tshuam uas cuam tshuam rau lub fluidity ntawm cov hlau casting yog feem ntau cov hauv qab no:
Alloy Muaj pes tsawg
Cov ntsiab lus carbon: Cov ntsiab lus carbon muaj cov ntsiab lus tseem ceeb ntawm cov xim ntawm cov hlau cam. Feem ntau hais lus, raws li cov ntsiab lus carbon ntau ntxiv, lub suab me me ntawm Molten Steel txo qis thiab cov fluidity txhim kho. Txawm li cas los xij, cov ntsiab lus carbon ntau dhau yuav ua rau muaj kev cuam tshuam ntau dhau thiab muaj feem ntau ntawm cov hlau, uas yuav txo tau cov fluidity.
Alloy Ntsiab: cov ntsiab lus xws li silicon thiab manganese tuaj yeem txo qhov kev sib tw melting ntawm cov hlau thiab txhim kho lub fluidity rau qee yam. Cov ntsiab xws li cov chromium, molybdenum, thiab tungsten yuav nce lub suab melting ntawm cov hlau thiab ua kom nws muaj kev tsis zoo.
Nchuav qhov kub
Lub siab dua cov dej ntws tawm, qhov ntau dua cov superheat ntawm Molten hlau, qis dua nws viscosity thiab nws zoo dua nws cov xim. Txawm li cas los xij, dhau ib qho siab dhau ib qho kub thiab txias yuav ua rau muaj kev nqus roj thiab ntau dua ntawm cov kab mob Molidation, thiab tej zaum kuj tseem tuaj yeem ua rau muaj kev tsis txaus siab thiab shrinkage qhov hauv cov duab.
Casting tej yam
Cov khoom siv casting: Cov khoom sib txawv casting muaj cov khoom thermal sib txawv. Cov ntaub ntawv nrog cov thermal zoo thermal caperivity yuav ua rau cov hlau molten hlau dissipate kub sai sai, qhov kub nce sai, thiab cov kua dej txo. Piv txwv li, cov thermal conductivity ntawm cov hlau pwm zoo dua li ntawm cov xuab zeb pwm, thiab cov kua ntawm cam khwb cia hauv cov hlau pwm yog cov neeg tsis zoo.
Huab cua permeability ntawm pwm: Cov pa huab cua zoo tso cai rau cov roj kab nrib pleb Yog tias huab cua permeability tsis zoo, cov roj yuav nthuav tawm hauv cov pwm kab noj hniav, uas yuav tsim rov qab lub siab rov qab thiab tabkaum ntawm cov hlau molten.
Doight Rougness ntawm cov pwm: Qhov me me ntawm cov pwm ntawm cov pwm, uas yog qhov me me tawm ntawm cov hlau me me thaum nws ntws tawm, thiab qhov zoo dua ntawm cov xim. Ntawm qhov tsis sib xws, ntxhib pwm nto yuav ua rau cov ntws tsis kam ntawm Molten hlau thiab txo kom muaj fluidity.
Casting qauv
Phab ntsa tuab ntawm cov cuab yeej: rau cov txheej txheem tuab, cov channel rau kev ntws yog qhov dav, cov cua sov tsis zoo, thiab cov fluidity yog qhov zoo dua. Txawm li cas los xij, rau nyias phab ntsa castings, Molten hlau dissipates kub sai sai thaum lub sij hawm ntws, yog yooj yim rau solorify, thiab muaj fluidity tsis zoo.
Kev nyuaj siab ntawm castings: castings nrog cov txheej txheem nyuaj, muaj ntau txoj kev sib sib zog nqus dej lossis sib sib zog nqus cov hlau thiab txo qis fluidity.
Melting txheej txheem
Kho kom zoo li degree: Zoo-zoo Molten Steel muaj siab heev, tsawg impurities thiab roj cov ntsiab lus, thiab cov kua zoo. Yog hais tias lub refining yog tsis txaus, yuav muaj ntau cov kev suav thiab roj hauv cov hlau molten, uas yuav cuam tshuam ntws ntawm Molten Steel thiab txo qis fluidity.
Melting sijhawm thiab ntsuas kub: tsim nyog tswj ntawm melting lub sijhawm thiab kub tau ua rau cov alloy ntsiab lus tag nrho, uas tau txais txiaj ntsig los txhim kho cov dej ntawm Molten hlau.
