Tungsten yesirivha
Ruzivo rweChigadzirwa
Matagi eChigadzirwa
Ningbo De-Shin inopa mhando dzakasiyana dzesirivha tungsten dzekushandisa mumaindasitiri akasiyana. Inotora nzira yepamusoro yekupinda muvacuum uye zvigadzirwa zvese zvinosangana nezvinodiwa zveGB/T8320-2003, ASTM B631.
Maitiro ekugadzira:musanganiswa weupfu –> kudzvanya –> sintering –> kupinda kwevacuum –> machining –> QC. Maitiro ese ekugadzira aya anodzorwa zvakanyanya neQC kuti ive nechokwadi chekuti mashandiro emhando yepamusoro anobudirira.
Zvakanakira:
1. Kufambisa magetsi kwakanyanya.
2. Kupisa kwakanyanya.
3. Kuwanda kwakanyanya uye kuumbwa kwezvinhu zvakafanana zvakakwana.
Mashandisirwo:
1. Zvinopwanya dunhu.
2. Zvinopwanya mvura inobuda pasi.
3. Zvidimbu zvidiki zvemagetsi.
4. electrode yekunamira inochinjika.
5. mugodhi unodzivirira kusakara
Saizi yemasheya:
Tsvimbo yesirivha yetungsten: dhayamita ≥0.5mm, kazhinji 1-60mm; kureba ≤300mm, kazhinji 100, 175, 200, 300mm.
Siliva tungsten sikweya bhaa: ukobvu ≥1.0mm, kazhinji 1-40mm; kureba & upamhi ≤400mm, kazhinji 100*200, 200*300, 200*400mm.
