Tekinoloje yopanga tungsten mbale

Powder metallurgy tungsten nthawi zambiri imakhala ndi njere yabwino, yopanda kanthu nthawi zambiri imasankhidwa ndi kutentha kwapamwamba komanso kugudubuza njira, kutentha kumayendetsedwa pakati pa 1500 ~ 1600 ℃.Pambuyo pa chopanda kanthu, tungsten imatha kupindika, kupukutidwa kapena kupindika.Kupanikizika kwa makina nthawi zambiri kumachitika pansi pa kutentha kwa recrystallization, chifukwa malire a njere a tungsten opangidwanso amakhala osasunthika, omwe amalepheretsa kugwira ntchito.Chifukwa chake, pakuwonjezeka kwa kuchuluka kwachulukidwe kwa tungsten, kutentha kwa mapindikidwe kumachepa chimodzimodzi.
Kugubuduza mbale ya Tungsten kumatha kugawidwa kukhala kugudubuza kotentha, kugudubuza kotentha komanso kuzizira kozizira.Chifukwa cha kukana kwakukulu kwa tungsten, odzigudubuza wamba sangathe kukwaniritsa zofunikira za mbale za tungsten, pamene zodzigudubuza zopangidwa ndi zipangizo zapadera ziyenera kuikidwa.Pogubuduza, zodzigudubuza ziyenera kutenthedwa, ndipo kutentha kwa preheating ndi 100 ~ 350 ℃ malinga ndi mikhalidwe yosiyanasiyana yogubuduza.Zopanda kanthu zimatha kupangidwa kokha pamene kachulukidwe kachibale (chiŵerengero cha kachulukidwe chenichenicho ku kachulukidwe kawongopeka) ndipamwamba kuposa 90%, ndipo ali ndi processibility yabwino pa kachulukidwe ka 92 ~ 94%.Kutentha kwa tungsten slab ndi 1,350 ~ 1,500 ℃ mu ndondomeko yotentha yogudubuza;ngati magawo a deformation asankhidwa molakwika, zosowekazo zitha kukhala zosanjikiza.Kutentha koyambira kwa kugudubuza kofunda ndi 1,200 ℃;8mm wandiweyani otentha adagulung'undisa mbale akhoza kufika makulidwe a 0.5mm kudzera ofunda Kugudubuza.Ma mbale a Tungsten ali ndi kukana kwa mapindikidwe ambiri, ndipo thupi la wodzigudubuza limatha kupindika ndikupunduka pakugubuduza, kotero kuti mbalezo zimapanga makulidwe osagwirizana ndi m'lifupi mwake, ndipo zitha kusweka chifukwa chamitundu yonse yopanda yunifolomu. zigawo mu wodzigudubuza kuwombola kapena kugubuduza mphero kuwombola ndondomeko.Kutentha kwa brittle-ductile kusintha kwa mbale za 0.5mm-thick ndi kutentha kwa chipinda kapena kuposa kutentha;ndi brittleness, mapepala ayenera adagulung'undisa mu mapepala wandiweyani 0.2mm pa kutentha 200 ~ 500 ℃.M'kupita kwanthawi, mapepala a tungsten amakhala ochepa komanso aatali.Kuonetsetsa kutentha yunifolomu ya mbale, graphite kapena molybdenum disulphide nthawi zambiri yokutidwa, zomwe sizothandiza kokha kutentha kwa mbale komanso zimakhala ndi mafuta odzola pakupanga makina.
