ka ipu hoohehee tungsten crucible no ka umu wela wela
ʻO Tungsten crucible kahi ʻano huahana tungsten metala, i māhele ʻia i ʻelua mau ʻano: sintering a me ka stamping. ʻO ke kaʻina hana hoʻomākaukau o ka tungsten crucible e pili ana i ke ʻano wili, ke ʻano stamping, etc. ʻO kēia mau kaʻina hana i ka tungsten crucible he kiʻekiʻe kiʻekiʻe, haʻahaʻa haʻahaʻa roughness, ikaika tensile maikaʻi a me ka paʻakikī, ʻoiai ke kumu kūʻai o ke kumukūʻai, a ʻo ke kumu kūʻai o ka huahana. .
ʻO ka hoʻohana ākea o nā crucibles tungsten e pōmaikaʻi mai kā lākou mau waiwai kino a me nā mea kemika, me ka helu heheʻe kiʻekiʻe, ka ikaika kiʻekiʻe, ka pale ʻana i ka corrosion maikaʻi, a me ke kūpaʻa ʻana. ?

1. Aia kā mākou hale hana ma Luoyang City, Henan Province. He wahi hana ʻo Luoyang no nā mines tungsten a me molybdenum, no laila, loaʻa iā mākou nā mea maikaʻi loa i ka maikaʻi a me ke kumukūʻai;
2. Loaʻa i kā mākou hui nā limahana loea me ka ʻoi aku o 15 mau makahiki o ka ʻike, a hāʻawi mākou i nā hoʻonā a me nā manaʻo no kēlā me kēia mea kūʻai aku.
3. ʻO kā mākou huahana a pau e nānā pono i ka maikaʻi ma mua o ka lawe ʻia ʻana aku.
4. Inā loaʻa iāʻoe nā waiwai hemahema, hiki iāʻoe ke hoʻokaʻaʻike mai iā mākou no ka uku.
1. E hoʻomākaukau i ka pauka tungsten
(ʻO ka mua, e hoʻomākaukau i ka pauka tungsten a nānā iā ia e hoʻokaʻawale i ka pauka tungsten maikaʻi a me ka maikaʻi)
2. Hui hui
(Ka hana ʻana o ka pauka tungsten me ka hoʻohui kemika like akā mai nā kaʻina hana like ʻole)
3. kaomi isostatic
(E kau i ka pauka tungsten i hui ʻia i loko o kahi pahu i hoʻopaʻa ʻia i hoʻopiha ʻia me ka wai, a kaomi mālie iā ia ma o kahi ʻōnaehana pressurization e hōʻemi i ka mamao ma waena o nā molekala, hoʻonui i ka nui, a hoʻomaikaʻi i nā waiwai kino o ka mea me ka ʻole o ka hoʻololi ʻana i kona helehelena)
4. ʻO ka mīkini billet ʻawaʻawa
(Ma hope o ka hoʻopau ʻana i ke kaomi isostatic, hoʻokō ʻia ka hana ʻana o ka billet)
5. Ka hoʻoheheʻe ʻana i ke alapine waena
(E hoʻokomo i ka billet ʻoʻoleʻa i hoʻopaʻa ʻia i loko o kahi umu hoʻoheheʻe ʻana i ke alapine no ka hana sintering)
6. Hana kaʻa maikaʻi
(Ke hoʻohuli ʻana i ka huahana sintered no ka loaʻa ʻana o nā ana a me nā ʻano kikoʻī)
7. E nānā i ka ʻeke
(E nānā i ka tungsten crucible i hana ʻia a hoʻopaʻa ʻia ma hope o ka hala ʻana o ka nānā)
ʻO ka hoʻoheheʻe ʻana o ke aniani Quartz: Hoʻohana nui ʻia nā kīʻaha Tungsten i nā kapuahi hoʻoheheʻe aniani quartz. Ma ke ʻano he mea nui no ka hoʻoheheʻe ʻana i ke aniani quartz, ʻo ko lākou ikaika wela kiʻekiʻe a me ka pale ʻana i ka corrosion e hiki ai i ke aniani quartz ke hoʻoheheʻe a hana i ke ʻano i makemake ʻia i nā wahi wela kiʻekiʻe.
ʻO ka deformation o ka crucible ma muli o ka hoʻonui ʻole ʻia o nā ʻāpana like ʻole o ka crucible ma muli o ka hoʻomehana nui a me ka ʻole. Pono e pale ʻia ka hoʻomehana wikiwiki a me ka like ʻole o ka crucible.
ʻO 1600-2500 degere Celsius ka pae wela i manaʻo ʻia.
