ʻO ke kila Tungsten (tungsten carbide) he mau waiwai maikaʻi loa e like me ka paʻakikī kiʻekiʻe, ke kūpaʻa ʻana, ka ikaika maikaʻi a me ka paʻakikī, ka pale wela a me ka pale ʻana i ka corrosion, ʻoi aku kona paʻakikī kiʻekiʻe a me ke kūpaʻa ʻana, ʻoiai ma kahi mahana o 500 ℃. ʻAʻole i hoʻololi ʻia, a ʻoi aku ka paʻakikī ma 1000 °C.

inoa Pākē: kila tungsten

He inoa haole: Cemented Carbide Alias

Nā hiʻohiʻona: ʻO ka paʻakikī kiʻekiʻe, ke kūpaʻa ʻana, ka ikaika maikaʻi a me ka paʻakikī

Nā huahana: ʻO ke koʻokoʻo pōʻai, ka pā kila tungsten

Hoʻolauna:

ʻO ke kila Tungsten, ka mea i ʻike ʻia he carbide cemented, e pili ana i kahi mea i hoʻopaʻa ʻia i hoʻopaʻa ʻia me hoʻokahi carbide metala. ʻO Tungsten carbide, cobalt carbide, niobium carbide, titanium carbide, a me tantalum carbide nā mea maʻamau o ke kila tungsten. ʻO ka nui o ka palaoa o ka ʻāpana carbide (a i ʻole ka pae) aia ma waena o 0.2-10 microns, a paʻa pū ʻia nā ʻōpala carbide me ka hoʻohana ʻana i kahi mea hoʻopili metala. ʻO ka mea hoʻopili maʻamau e pili ana i ka cobalt metala (Co), akā no kekahi mau noi kūikawā, hiki ke hoʻohana ʻia ka nickel (Ni), hao (Fe), a i ʻole nā ​​metala ʻē aʻe. ʻO ka hui pū ʻana o ka carbide a me ka binder phase e hoʻoholo ʻia e kapa ʻia ʻo "ka papa".

Lawe ʻia ka hoʻohālikelike ʻana o ke kila tungsten e like me nā kūlana ISO. Hoʻokumu ʻia kēia hoʻokaʻawale ʻana i ke ʻano mea o ka mea hana (e like me nā māka P, M, K, N, S, H). Hoʻohana nui ʻia ka ʻāpana binder no kona ikaika a me ka pale ʻana i ka corrosion.

ʻO ka matrix o ke kila tungsten he ʻelua mau ʻāpana: hoʻokahi ʻāpana ka pae paʻakikī; ʻo ka ʻaoʻao ʻē aʻe ka metala paʻa. ʻO nā metala paʻa he mau metala hui hao, hoʻohana mau ʻia ka cobalt a me ka nickel. No laila, aia nā tungsten-cobalt alloys, tungsten-nickel alloys a me tungsten-titanium-cobalt alloys.

No nā kila i loaʻa i ka tungsten, e like me ke kila kiʻekiʻe a me kekahi mau mea hana wela, hiki i ka tungsten content i ke kila ke hoʻomaikaʻi nui i ka paʻakikī a me ka pale wela o ke kila, akā e hāʻule nui ka paʻakikī.

ʻO ka noi nui o nā kumu waiwai tungsten he carbide cemented, ʻo ia hoʻi, ke kila tungsten. ʻO Carbide, i kapa ʻia ʻo nā niho o ka ʻoihana hou, hoʻohana nui ʻia i nā huahana tungsten steel.

ʻO ke ʻano mea hoʻohui

Kaʻina hana hoʻoheheʻe:

ʻO ka sintering o ke kila tungsten ke kaomi ʻana i ka pauka i loko o kahi billet, a laila e hoʻokomo i ka umu sintering e wela ai i kahi mahana (sintering temperature), e mālama iā ia no kekahi manawa (manawa paʻa), a laila hoʻomaha ia, i loaʻa ai. ka mea kila tungsten me nā mea pono.

ʻEhā mau pae kumu o ke kaʻina hana sintering kila tungsten:

1. I ka wā o ka wehe ʻana i ka mea hana a me ka pre-sintering, e hoʻololi ke kino sintered i kēia mau hoʻololi i kēia pae:

ʻO ka wehe ʻana i ka mea hoʻoheheʻe ʻia, me ka piʻi ʻana o ka mahana i ka pae mua o ka sintering, e hoʻoheheʻe ʻia a hoʻoheheʻe ʻia ka mea hoʻoheheʻe, a kāpae ʻia ke kino sintered. ʻOkoʻa ke ʻano, ka nui a me ke kaʻina hana sintering.

Hoʻemi ʻia nā oxides ma ka ʻili o ka pauka. I ka mahana sintering, hiki i ka hydrogen ke hoʻemi i nā oxides o ka cobalt a me ka tungsten. Inā hoʻoneʻe ʻia ka mea hana i loko o ka momi a hoʻopaʻa ʻia, ʻaʻole ikaika ka hopena carbon-oxygen. Hoʻopau mālie ʻia ke koʻikoʻi pili ma waena o nā ʻāpana pauka, hoʻomaka ka hoʻihoʻi hou ʻana o ka pauka metala paʻa, hoʻomaka ka diffusion o ka ʻili, a hoʻomaikaʻi ʻia ka ikaika briquetting.

2. Ke kahua hoʻopaʻa paʻa (800 ℃——eutectic wela)

I ka mahana ma mua o ka ʻike ʻia ʻana o ka pae wai, ma kahi o ka hoʻomau ʻana i ke kaʻina hana o ka pae mua, ua hoʻoikaika ʻia ka hopena paʻa a me ka diffusion, hoʻonui ʻia ka kahe plastic, a emi nui ke kino sintered.

3. ʻO ka pae hoʻoheheʻe wai (eutectic temperature – sintering temperature)

Ke ʻike ʻia ka ʻāpana wai i loko o ke kino i hoʻopaʻa ʻia, hoʻopau koke ʻia ka hōʻemi ʻana, a ukali ʻia e ka hoʻololi crystallographic e hana i ke ʻano kumu a me ke ʻano o ka alloy.

4. Kūlana hoʻoluʻu (sintering temperature - lumi wela)

I kēia pae, ʻo ke ʻano a me ka hoʻohui ʻana o ke kila tungsten i kekahi mau loli me nā kūlana hoʻomaha like ʻole. Hiki ke hoʻohana ʻia kēia hiʻohiʻona e hoʻomaʻamaʻa i ke kila tungsten e hoʻomaikaʻi i kona ʻano kino a me ka mechanical.

Hoʻolauna noi

Aia ke kila Tungsten i ka carbide cemented, i ʻike ʻia ʻo tungsten-titanium alloy. Hiki i ka paʻakikī ke hiki i 89 ~ 95HRA. Ma muli o kēia, ʻaʻole maʻalahi nā huahana tungsten steel (nā wati kila tungsten maʻamau) e hoʻohana, paʻakikī a makaʻu ʻole i ka annealing, akā palupalu.

ʻO nā mea nui o ka carbide cemented he tungsten carbide a me ka cobalt, nona ka 99% o nā mea āpau, a ʻo 1% nā metala ʻē aʻe, no laila ua kapa ʻia ʻo tungsten steel.

Hoʻohana maʻamau i ka mīkini paʻa kiʻekiʻe, nā mea paahana kiʻekiʻe, nā lathes, nā ʻāpana drill hopena, nā ʻoki ʻoki aniani, nā ʻoki tile, paʻakikī a ʻaʻole makaʻu i ka annealing, akā palupalu. No ka metala laha ole.

ʻO ke kila Tungsten (tungsten carbide) he mau waiwai maikaʻi loa e like me ka paʻakikī kiʻekiʻe, ke kūpaʻa ʻana, ka ikaika maikaʻi a me ka paʻakikī, ka pale wela a me ka pale ʻana i ka corrosion, ʻoi aku kona paʻakikī kiʻekiʻe a me ke kūpaʻa ʻana, ʻoiai ma kahi mahana o 500 ℃. ʻAʻole i hoʻololi ʻia, a ʻoi aku ka paʻakikī ma 1000 °C. Hoʻohana nui ʻia ʻo Carbide ma ke ʻano he mea, e like me nā mea hoʻohuli, nā mea ʻoki wili, nā mea hoʻolālā, nā drills, nā mea hoʻoluhi, a me nā mea ʻē aʻe, no ka ʻoki ʻana i ka hao, nā metala non-ferrous, plastics, nā mea kemika, graphite, aniani, pōhaku a me ke kila maʻamau, a hiki ke hoʻohana ʻia no ka ʻoki ʻana i ke kila kūpaʻa. ʻO nā mea paʻakikī i ka mīkini e like me ke kila wela, ke kila kila, ke kila manganese kiʻekiʻe, ke kila mea hana, a me nā mea'ē aʻe.

Hiki ke hoʻohana ʻia ke kila Tungsten (tungsten carbide) e hana i nā mea ʻeli pōhaku, nā mea hana mining, nā mea hana wili, nā mea ana, nā ʻāpana kūʻokoʻa, nā abrasive metala, nā linings cylinder, nā bearings precision, nozzles, etc.

Hoʻohālikelike o nā māka kila tungsten: S1, S2, S3, S4, S5, S25, M1, M2, H3, H2, H1, G1 G2 G5 G6 G7 D30 D40 K05 K10 K20 YG3X YG3 YG4C YG6 YG8 YG10 YG12 YL6 YG20 YG25 YG28YT5 YT14 YT15 P10 P20 M10 M20 M30 M40 V10 V20 V30 V40 Z01 Z10 Z20 Z30

ʻO ke kila Tungsten, nā pahi carbide cemented, a me nā ʻano kikoʻī maʻamau tungsten carbide he nui ka waihona, a loaʻa nā blanks mai ka waihona.

Moʻo waiwai
