ZhenAn Me Tungsten Crucible Chaw tsim tshuaj paus
Cov khoom siv tseem ceeb siv hauvtungsten crucible
Tungsten crucible yog tsim los ntawm tungsten hmoov raw khoom.
Tungsten phaj dov tuaj yeem muab faib ua kub dov, sov dov thiab txias dov.
Vim lub siab deformation tsis kam ntawm tungsten, zoo tib yam rollers tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua rau dov tungsten daim hlau, thiab cov ntaub ntawv tshwj xeeb yuav tsum tau siv.
Thaum lub sij hawm dov, cov yob yuav tsum tau preheated, thiab lub preheating kub yog 100 mus rau 350 degree raws li txawv dov tej yam kev mob. Qhov dawb paug tuaj yeem ua tiav tsuas yog thaum tus txheeb ze ntom ntom (qhov sib piv ntawm qhov tseeb qhov ceev thiab qhov ntsuas qhov tseeb) ntau dua 90%.
Qhov kev ua tau zoo yog qhov zoo thaum qhov khoob khoob ntawm 92 thiab 94%. Lub billet qhib kub ntawm kub dov yog nruab nrab ntawm 1350 thiab 1500 degree. Yog hais tias cov txheej txheem deformation tsis raug xaiv kom raug, lub billet yuav delamination.
Qhov pib kub ntawm qhov sov dov yog 1200 degree, thiab lub thickness ntawm lub phaj kub dov nrog lub thickness ntawm 8 hli tuaj yeem ncav cuag 0.5 hli tom qab sov dov.
Vim lub siab deformation tsis kam ntawm tungsten phaj, yob lub cev khoov thiab deforms thaum dov, uas ua rau lub thickness tsis sib npaug ntawm lub phaj raws qhov dav kev taw qhia. Thaum hloov rolls los yog dov mills, lub phaj yuav tawg vim tsis sib xws deformation nyob rau hauv ntau qhov chaw.
Cov yas-nkig hloov kub ntawm 0.5 hli tuab phaj tseem nyob ntawm lossis siab dua chav tsev kub, thiab daim ntawv yog nkig. Daim ntawv yuav tsum tau dov mus rau 0.2 hli ntawm 200 ~ 500 degree . Nyob rau theem tom qab ntawm dov, cov ntawv tungsten yog nyias thiab ntev. Txhawm rau kom ntseeg tau tias lub phaj yog rhuab sib npaug, nws feem ntau coated nrog graphite lossis molybdenum disulfide, uas tsis yog tsuas yog muaj txiaj ntsig zoo rau cov cua sov ntawm lub phaj, tab sis kuj muaj cov nyhuv lubrication thaum ua.
