Hoʻolauna:

ʻO ke kila tungsten, i ʻike ʻia hoʻi he carbide cemented, e pili ana i kahi mea hui sintered i loaʻa ma ka liʻiliʻi o hoʻokahi carbide metala. ʻO ka tungsten carbide, cobalt carbide, niobium carbide, titanium carbide, a me ka tantalum carbide nā ʻāpana maʻamau o ke kila tungsten. ʻO ka nui o ka palaoa o ka ʻāpana carbide (a i ʻole ka pae) ma waena o 0.2-10 microns, a ua hoʻopaʻa ʻia nā hua carbide me ka hoʻohana ʻana i kahi mea hoʻopaʻa metala. ʻO ka mea hoʻopaʻa 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 a me nā alloys. ʻO ka hui pū ʻana o ka carbide a me ka pae mea hoʻopaʻa e hoʻoholo ʻia ua kapa ʻia ʻo "grade".

Hoʻokō ʻia ka hoʻokaʻawale ʻana o ke kila tungsten e like me nā kūlana ISO. Hoʻokumu ʻia kēia hoʻokaʻawale ʻana ma ke ʻano o ka mea hana (e like me nā papa P, M, K, N, S, H). Hoʻohana nui ʻia ka haku mele pae mea hoʻopaʻa no kona ikaika a me ke kūpaʻa i ka pala.

ʻElua ʻāpana o ke kila tungsten: ʻo kekahi ʻāpana ka pae paʻakikī; ʻo kekahi ʻāpana ka metala hoʻopaʻa. ʻO nā metala hoʻopaʻa he mau metala hui hao maʻamau, cobalt a me nickel i hoʻohana pinepine ʻia. No laila, aia nā hui tungsten-cobalt, nā hui tungsten-nickel a me nā hui tungsten-titanium-cobalt.

No nā kila i loaʻa ka tungsten, e like me ke kila wikiwiki a me kekahi mau kila make hana wela, hiki i ka nui o ka tungsten i loko o ke kila ke hoʻomaikaʻi nui i ka paʻakikī a me ke kūpaʻa wela o ke kila, akā e hāʻule nui ka paʻakikī.

ʻO ka hoʻohana nui ʻana o nā kumuwaiwai tungsten he carbide cemented, ʻo ia hoʻi, ke kila tungsten. ʻO Carbide, i ʻike ʻia ʻo nā niho o ka ʻoihana hou, hoʻohana nui ʻia i nā huahana kila tungsten.

ʻAno o nā mea hoʻohui

Kaʻina hana sintering:

ʻO ke 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 hoʻomehana i kahi mahana (mahana sintering), mālama iā ia no kekahi manawa (manawa paʻa), a laila e hoʻomāalili iā ia, i mea e loaʻa ai ka mea kila tungsten me nā waiwai e pono ai.

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

1. I ke kahua o ka wehe ʻana i ka mea hoʻokumu a me ka pre-sintering, e loli ana ke kino sintered i kēia mau hoʻololi i kēia manawa:

Ke wehe ʻia ka mea hoʻoheheʻe ʻia, me ka piʻi ʻana o ka mahana i ka wā mua o ka sintering, e palaho mālie a mahu paha ka mea hoʻoheheʻe ʻia, a ua kāpae ʻia ke kino sintered. He ʻokoʻa ke ʻano, ka nui a me ke kaʻina hana sintering.

Hoʻemi ʻia nā oxides ma luna o ka pauka. Ma ka mahana sintering, hiki i ka hydrogen ke hoʻemi i nā oxides o ka cobalt a me ka tungsten. Inā wehe ʻia ka mea hana i loko o ka vacuum a sintered, ʻaʻole ikaika ka hopena kalapona-oxygen. Hoʻopau mālie ʻia ke koʻikoʻi pili ma waena o nā ʻāpana pauka, hoʻomaka ka pauka metala hoʻopaʻa e hoʻōla a hana hou, hoʻomaka ka hoʻolaha ʻana o ka ʻili, a hoʻomaikaʻi ʻia ka ikaika briquetting.

2. Kahua sintering pae paʻa (800 ℃——mahana eutectic)

Ma ka mahana ma mua o ka ʻike ʻia ʻana o ka pae wai, me ka hoʻomau ʻana i ke kaʻina hana o ke kahua ma mua, ua hoʻoikaika ʻia ka hopena paʻa a me ka hoʻolaha ʻana, ua hoʻonui ʻia ke kahe plastik, a ua emi nui ke kino sintered.

3. Kahua sintering pae wai (mahana eutectic - mahana sintering)

Ke ʻike ʻia ke ʻano wai i loko o ke kino sintered, hoʻopau koke ʻia ka emi ʻana, a ukali ʻia e ka hoʻololi crystallographic e hana i ke ʻano kumu a me ke ʻano o ka metala.

4. Kahua hoʻoluʻolu (mahana sintering - mahana lumi)

I kēia pae, loaʻa kekahi mau loli i ke ʻano a me ka hoʻohuihui ʻana o ke kila tungsten me nā kūlana hoʻoluʻu like ʻole. Hiki ke hoʻohana ʻia kēia hiʻohiʻona e hoʻomehana i ke kila tungsten e hoʻomaikaʻi i kona mau waiwai kino a me ka mechanical.

Hoʻolauna noi

No ke kila tungsten ka carbide cemented, i ʻike ʻia hoʻi he tungsten-titanium alloy. Hiki i ka paʻakikī ke hiki i 89 ~ 95HRA. Ma muli o kēia, ʻaʻole maʻalahi ke komo ʻana i nā huahana kila tungsten (nā wati kila tungsten maʻamau), paʻakikī a ʻaʻole makaʻu i ka annealing, akā he palupalu.

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

Hoʻohana pinepine ʻia i ka mīkini ʻana i ke kiko kiʻekiʻe, nā mea hana kiko kiʻekiʻe, nā mīkini lathes, nā ʻāpana wili hopena, nā ʻāpana ʻokiʻoki aniani, nā ʻokiʻoki tile, paʻakikī a ʻaʻole makaʻu i ka annealing, akā palupalu. No ka metala kakaikahi.

Loaʻa i ke kila tungsten (tungsten carbide) kahi moʻo o nā waiwai maikaʻi loa e like me ka paʻakikī kiʻekiʻe, ke kūpaʻa ʻana i ka ʻaʻahu, ka ikaika maikaʻi a me ka paʻakikī, ke kūpaʻa wela a me ke kūpaʻa ʻana i ka corrosion, ʻoiai kona paʻakikī kiʻekiʻe a me ke kūpaʻa ʻana i ka ʻaʻahu, ʻoiai ma ka mahana o 500 ℃. Noho mau ia me ka ʻole o ka loli, a he paʻakikī kiʻekiʻe nō hoʻi ma 1000 °C. Hoʻohana nui ʻia ka Carbide ma ke ʻano he mea hana, e like me nā mea hana huli, nā mea ʻoki wili, nā planers, nā drills, nā mea hana wili, a pēlā aku, no ka ʻoki ʻana i ka hao i hoʻolei ʻia, nā metala non-ferrous, nā plastics, nā fibers kemika, graphite, ke aniani, ka pōhaku a me ke kila maʻamau, a hiki ke hoʻohana ʻia no ka ʻoki ʻana i ke kila kūpaʻa. ʻO nā mea paʻakikī e mīkini e like me ke kila wela, ke kila kila, ke kila manganese kiʻekiʻe, ke kila mea hana, a pēlā aku. ʻO ka wikiwiki o ka ʻoki ʻana o ka carbide cemented hou he mau haneli manawa o ke kila kalapona.

Hiki ke hoʻohana ʻia ke kila tungsten (tungsten carbide) e hana i nā mea hana ʻeli pōhaku, nā mea hana mining, nā mea hana ʻeli, nā mea ana, nā ʻāpana pale ʻaʻahu, nā mea hoʻopailua metala, nā uhi cylinder, nā bearings precision, nā nozzles, a pēlā aku.

Hoʻohālikelike o nā papa 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 YL10.2 YL60 YG15 YG20 YG25 YG28YT5 YT14 YT15 P10 P20 M10 M20 M30 M40 V10 V20 V30 V40 Z01 Z10 Z20 Z30

He nui ka waihona o ke kila tungsten, nā pahi carbide cemented, a me nā kikoʻī maʻamau tungsten carbide like ʻole, a loaʻa nā blanks mai ka waihona.
