Kev tsim cov tungsten skeins feem ntau muaj ob peb kauj ruam:

tungsten hlau xaiv: Siv high-purity tungsten hlau ua raw khoom. Cov hlau raug xaiv rau nws lub zog tshwj xeeb, siab melting point thiab corrosion kuj, ua rau nws haum rau siv nyob rau hauv high kub daim ntaub ntawv. Hlau annealing: Cov tungsten hlau uas tau xaiv tau raug muab tshem tawm los txhim kho nws cov ductility thiab pab txhawb txoj kev sib tw tom ntej. Annealing yog cua sov cov hlau mus rau qhov kub thiab txias thiab maj mam txias, uas pab tshem tawm cov kev ntxhov siab sab hauv thiab ua rau cov hlau ntau dua. Cov txheej txheem twisting: Lub annealed tungsten hlau yog ces twisted los tsim cov qauv filament. Cov txheej txheem twisting yog ua tib zoo tswj kom ntseeg tau tias qhov xav tau filament qhov ntev thiab cov khoom siv tshuab ua tiav. Kev kho cua sov: Cov xov hlau twisted tungsten yog raug rau cov txheej txheem kho cua sov kom ntxiv dag zog rau nws cov khoom siv xws li lub zog thiab ductility. Cov kauj ruam no yuav suav nrog cua sov lub filament mus rau ib qho kub thiab txias nws nyob rau hauv kev tswj tej yam kev mob kom tau raws li qhov xav tau metallographic qauv. Kev Tswjhwm Zoo thiab Kev Ntsuas: Thoob plaws hauv tag nrho cov txheej txheem tsim khoom, kev tswj xyuas kev ua tau zoo yog siv los xyuas kom meej tias cov tungsten hlau ua tau raws li qhov yuav tsum tau ua. Qhov no yuav suav nrog kev sim cov filament lub zog txhua yam, qhov tseeb qhov tseeb thiab lwm yam khoom tseem ceeb. Kev ua tiav kawg: Thaum tungsten strands dhau qhov kev tshuaj xyuas zoo, lawv tuaj yeem dhau mus ua cov kauj ruam ntxiv, xws li kev kho deg lossis daim ntawv thov txheej, txhawm rau txhim kho lawv cov kev ua tau zoo hauv cov ntawv thov tshwj xeeb.

Kev tsim cov tungsten stranded hlau yuav tsum tau precision manufacturing cov tswv yim thiab ua tib zoo tswj ntawm cov khoom siv los xyuas kom meej tias cov hlau ua tau raws li qhov kub thiab txias yuav tsum tau muaj nyob rau hauv cov kev siv xws li semiconductor manufacturing.
