ʻO ka pauka Tungsten Carbide Spherical

1. He aha ka Spherical Cast Tungsten Carbide Powder?

ʻO ka pauka spherical tungsten carbide i loko o nā ʻāpana hina hina, i hana ʻia e ka ultra high-temperature spheroidization a i ʻole ke kaʻina atomization gas.

ʻO ka hale aniani dendritic i haku ʻia me WC a me W2C: kahi heheʻe kiʻekiʻe (2525 ℃), paʻakikī kiʻekiʻe (HV0.1≥2700), ʻano hulu kiʻekiʻe (maʻiʻo≥90%), paʻa kemika, kahe maikaʻi loa, microhardness kiʻekiʻe, a me ke kūpaʻa lole kiʻekiʻe. .

Hoʻohana ʻia kēia huahana no nā mea hoʻoheheʻe ʻaila daimana drill bit matrix, plasma (PTA) mea hoʻoheheʻe ʻia, nā mea hoʻoheheʻe hoʻoheheʻe ʻia, a me nā electrodes aahu ʻia i ka carbide.

2. Pehea e hana ai?

Hana ʻia ka pauka spherical tungsten carbide mai ka mana tungsten carbide maʻamau a i ʻole ka hui ʻana o tungsten (W), tungsten carbide (WC), a me carbon (C). ʻElua mau kaʻina hana: (1) hoʻoheheʻe mua ʻia ka hui ʻana o ka pauka tungsten i hui ʻia me ka tungsten carbide a me ka pauka kalapona. Hoʻokomo ʻia ka hui hoʻoheheʻe ʻia e ka rotation atomizing a i ʻole ka hoʻoheheʻe ʻana o ka wela kiʻekiʻe a me ke kaʻina hana atomizing. Hoʻopili ia i nā ʻāpana spherical WC i ka wā o ke kaʻina paʻa paʻa ma muli o ke ʻano o ka ʻili. (2) Hoʻokumu ʻia kekahi kaʻina hana ma ka hoʻololi ʻana o ka pauka tungsten carbide maʻamau. Hoʻohana ʻia ka hoʻoheheʻe ʻana i ka plasma, ka hoʻoulu uila, a i ʻole ka hoʻoheheʻe ʻana i ka umu hoʻoheheʻe uila i ka wā o ke kaʻina hana spheroidization e loaʻa ai nā ʻāpana spherical WC maikaʻi.

3. Pehea kona hana kino ana?

Hiki ke hoʻopaʻa ʻia ka nui kalapona maʻiʻo;

Hoʻolālā ʻelua ʻāpana W2C a me WC;

Microhardness kiʻekiʻe (HV0.1≥2700);

Maʻemaʻe kiʻekiʻe (≥99.9%);

Haʻahaʻa oxygen (≤100ppm);

Kiʻekiʻe sphericity (≥98 %);

ʻili pahee;

ʻAʻohe pōlele ukali;

Hoʻolikelike ka nui o nā ʻāpana;

Nā waiwai kahe maikaʻi (≤6.0s/50g);

Kiʻekiʻe puʻupuʻu nui (≥9.5g/cm3);

Paʻa paʻa (≥10.5g/cm3).

ʻO ka pauka tungsten carbide spherical i loaʻa ka microstructure o nā dendrites equiaxed maikaʻi, e like me ka mea i hōʻike ʻia ma ke kiʻi ma luna. Hōʻike maopopo ʻia ke kiʻi SEM ma lalo i kona ʻano ʻano o nā ʻāpana spherical WC homogeneous homogeneous. Mālama ʻo ia i nā waiwai kemika paʻa, ʻoluʻolu maikaʻi a me ka paʻakikī, a me ke kūpaʻa kūʻokoʻa / abrasion. Mai ka 0.025 mm a i ka 0.25 mm ka nui o ka nui o ka pauka spherical wc, e hōʻike ana i ka ʻulaʻula hina hina. ʻO kona kiko kikoʻī he 15.8 ~ 16.7 g / cm3 me ka micro-hardness mai 2700 ~ 3300 kg / mm2.

4. He aha kāna mau noi?

Hoʻohana nui ʻia ka pauka spherical tungsten carbide no ka hoʻopaʻa ʻana i nā bits drilling a me nā mea hana drill PDC, HVOF a i ʻole PTA thermal spray ma nā ʻaoʻao o nā noho valve a i ʻole nā ​​​​wahi o loko, a me ka weld overlay ma ka flange e kū pono ana i nā wahi, etc.

Inā makemake ʻoe i nā huahana tungsten carbide a makemake ʻoe i ka ʻike hou aʻe a me nā kikoʻī, hiki iā ʻoe ke CONTACT US ma ke kelepona a i ʻole leka uila ma ka hema, a i ʻole SEND US MAIL ma lalo o ka ʻaoʻao.
