Tungsten Swaging

Rotary forging yog ib txoj kev ua cov yas ntau rau kev tsim cov tungsten hlau blanks thiab nyias rods. Cov pas nrig ntawm qhov sib txawv yog rhuab mus rau 1400-1600 ° C nyob rau hauv ib qho chaw hydrogen thiab forged ntawm ntau hom rotary forging tshuab. Lub deformation ntawm qhov pib dhau yuav tsum tsis txhob loj dhau, thiab tom qab ntawd qhov deformation tuaj yeem tsim nyog nce ntxiv. Graphite lubrication yog siv nruab nrab ntawm lub workpiece thiab tuag thaum lub sij hawm swaging deformation txheej txheem. Qhov ceev ntawm cov txheej txheem tungsten pas nrig tuaj yeem ncav cuag 18.8 ~ 19.2g / cm3. Txij li thaum lub billet yog forged mus rau hauv ib puag ncig billet, lub deformation ntawm txhua feem yog sib txawv, uas ua rau cov qauv tsis sib xws. Lub sijhawm no, recrystallization annealing yuav tsum tau ua. Qhov kawg txoj kab uas hla ntawm swaging bar yog hais txog 3 mm.
