Yuav Roll Loj - loj tungsten daim hlau li cas?

Pure tungsten phaj feem ntau yog npaj los ntawm cov hmoov metallurgy txoj kev, thiab txawv thicknesses, qhov ntau thiab tsawg thiab cov khoom ntawm tungsten phaj billets yog tsim los ntawm cov cua kub dov txoj kev. Kev txhim kho yav tom ntej ntawm tungsten daim hlau yog qhov loj, zoo thiab tus nqi qis. Los ntawm kev npaj loj ib qho hnyav thiab loj loj tungsten phaj billets, ua kom kub dov deformation thiab sib txuas nrog cov txheej txheem kho cua sov, zoo dua thiab kev ua tau zoo tuaj yeem ua tiav. Tam sim no, ib qho hnyav ntawm tungsten phaj billets feem ntau tsawg dua 100 kg, thiab cov tuab feem ntau tsawg dua 50 hli. Kev tshawb fawb ntawm kub dov ntawm tungsten phaj billets nrog loj qhov hnyav thiab thickness tsis txaus. Daim ntawv no siv DEFORM software los ua qhov kub dov simulation ntawm loj- loj tungsten phaj billets, muab cov kev qhia yooj yim theoretical rau kev ua kom zoo ntawm loj- loj tungsten phaj billet kub dov tshuab thiab kev txhim kho kev ua tau zoo.

Hauv kev tsim khoom tiag tiag, tungsten phaj nrog qhov ntev ntawm 64 mm × 660 mm × 530 mm thiab ib qho hnyav ntawm 414 kg tau npaj los ntawm sintering. Tus txheeb ze ntom ntom ntawm sintering mus txog 96%, thiab qhov nruab nrab grain loj yog tsawg dua los yog sib npaug rau 40 μm. Kev taw qhia los ntawm cov ntaub ntawv thiab dov txoj kev nyob rau hauv Table 2 rau kub dov simulation, cross dov tau ua nrog txhua qhov kev hla rov qab. Tom qab 5 hla dhau, qhov nruab nrab dhau qhov deformation yog 26%, thiab tungsten phaj billet nrog qhov zoo ntawm 14.1 hli × 1190 hli × 1235 hli tau ua tiav tiav. Tag nrho cov deformation tus nqi yog 78%, thiab macroscopic morphology yog qhia nyob rau hauv daim duab 7. Qhov no muab kev npaj zoo rau lub tom ntej dov ntawm loj -sized tungsten phaj billets nrog ib tug luj ntau tshaj 800 kg thiab ib tug tuab ntau tshaj 80 mm.
