Niaj hnub no, cia saib nws cov kev tsim khoom thiab sib tham txog qhov siab - precision tooj dag sawb! Siab - precision brass strip yog lub tooj dub alloy sawb fequensal qhov tseeb, zoo nkauj heev cov khoom siv. Nws yog dav siv hauv cov khoom siv hluav taws xob, tshuab ua kom zoo, ib qho chaw, thiab lwm thaj teb, xws li cov txuas, npog cov ntaub thaiv npog, thiab txoj haujlwm loj.
Cov txheej txheem ntau lawm rau siab - precision tooj dag sawb, nias ua haujlwm, kho cua sov, thiab kev kuaj cua sov Hauv qab no yog cov txheej txheem tseem ceeb ntws thiab cov ntsiab lus tseem ceeb:
1. Cov Khoom Siv Khoom Siv: Kev tswj hwm ntawm Alloy Muaj pes tsawg leeg
1. Batching thiab melting
-} Alloy Alloy Composition: ib txwm muaj siab dua (} {% {% Kuj). Cov txheej txheem melting: Lub tshuab nqus dej melting los yog nruab nrab ntawm cov hluav taws xob tsis sib xws ntawm 1100-1200℃los tiv thaiv zinc volatilization (zinc boiling taw tes yog 907 degree) thiab ntsuas kev sib cais.
Tus neeg sawv cev npog (xws li hluav ncaig) yog ntxiv rau cais cov cua thiab txo cov oxidation. Nitrogen lossis Argon roj tau qhia thaum lub sijhawm tom qab ntawd melting kom tshem tawm cov kev suav nrog lossis sib npaug rau 0.005%, roj cov ntsiab lus tsawg dua lossis sib npaug rau 5 ppm).
2. Cov txheej txheem ua pov tseg
Nruam casting: kab rov tav lossis upward chancessioning yog siv. Ingot ntau npaum li cas yog feem ntau yog 20-50 hli tuab thiab 100-300 mm dav.
Cov Tseem Ceeb Tswj: Tus Nqi Cua Txias: Cov Pwm Dej Kub yog tswj hwm ntawm 0.5-2 m / min kom paub tseeb tias muaj 50 μm) thiab qhov tsis muaj kev ua kom muaj qhov txhab lossis cov cua. Innot Annaling: Homogenization annealing yog ua tam sim ntawd tom qab ua tam sim ntawd tom qab ua tam sim ntawd tom qab ua rau 2-4 teev) kom tshem tawm dendritic cais kev thiab txhim kho kub dov kev.
Ii. Plastic Processing: Multi-pass rolling achieves high precision
