Lub tshuab nqus tsev casting tau revolutionized zus tau tej cov high -kev ua tau zoo alloy steel Cheebtsam, muab superior metallurgical zoo, qhov tseeb qhov tseeb, thiab txhua yam khoom piv rau cov tsoos casting txoj kev. Cov txheej txheem qib siab no tshwj xeeb tshaj yog muaj txiaj ntsig hauv kev lag luam uas xav tau cov geometry nyuaj, lub zog siab, thiab kev tiv thaiv corrosion, xws li aerospace, tsheb, thiab kev tsim khoom siv kho mob.
1. Lub tshuab nqus tsev Casting yog dab tsi?
Lub tshuab nqus tsev casting yog cov hlau precision- txheej txheem uas molten alloy steel yog nchuav rau hauv pwm raws li kev tswj lub tshuab nqus tsev, txo cov roj porosity thiab oxidation. Txoj kev no ua ke cov ntsiab lus ntawm peev casting thiab nqus induction melting (VIM) los tsim ze rau -net- cov khoom zoo sib xws nrog kev ncaj ncees tshwj xeeb.
Cov kauj ruam tseem ceeb:
1. Kev npaj pwm- Ceramic lossis graphite pwm yog tsim los ntawm 3D-cov qauv luam tawm lossis CNC- cov qauv ua qauv.
2. Nqus Melting- Alloy steel yog yaj nyob rau hauv lub tshuab nqus tsev induction rauv kom tshem tawm impurities.
3. Tswj Pouring-Molten hlau yog kis mus rau hauv pwm nyob rau hauv lub tshuab nqus tsev vacuum los tiv thaiv huab cua nkag.
4. Solidification & Txias- Lub tshuab nqus tsev ib puag ncig ua kom cov cua txias tsis sib xws, txo cov kev ntxhov siab seem.
5. Tshaj tawm -Kev ua haujlwm- Kev kho cua sov (piv txwv li, HIP - Kub Isostatic Pressing) txhim kho cov khoom siv kho tshuab.
2. Qhov zoo ntawm Nqus Casting rau Alloy Steel
