Tungsten simbi (tungsten carbide) ine nhevedzano yezvivakwa zvakanakisa senge kuomarara kwakanyanya, kupfeka kuramba, simba rakanaka uye kuomarara, kupisa kupisa uye kusaita ngura, kunyanya kuomarara kwayo uye kupfeka kuramba, kunyangwe patembiricha ye500 ℃. Iyo inoramba isingachinjiki, uye ichine kuomarara kwakanyanya pa1000 ° C.

Chinese zita: tungsten simbi

Zita rekunze: Cemented Carbide Alias

Zvimiro: Kuomarara kwakanyanya, kupfeka kuramba, simba rakanaka uye kuoma

Zvigadzirwa: Round rod, tungsten simbi ndiro

Nhanganyaya:

Tungsten simbi, inozivikanwawo secemented carbide, inoreva chinhu chakasimwa chakaumbwa chine kanenge kamwe simbi carbide. Tungsten carbide, cobalt carbide, niobium carbide, titanium carbide, uye tantalum carbide zvinhu zvakajairika zvetungsten simbi. Saizi yezviyo yechikamu checarbide (kana chikamu) chinowanzova pakati pe 0.2-10 microns, uye tsanga dzecarbide dzinobatwa pamwechete uchishandisa simbi inosunga. Iyo binder inowanzoreva simbi cobalt (Co), asi kune mamwe maapplication akakosha, nickel (Ni), iron (Fe), kana mamwe simbi nemaaloyi anogona kushandiswa zvakare. Musanganiswa wemusanganiswa we carbide uye binder phase ichatemwa inodaidzwa se "giredhi".

Kurongeka kwe tungsten simbi kunoitwa zvinoenderana ne ISO zviyero. Uku kupatsanurwa kunoenderana nerudzi rwezvinhu zvechishandiso (senge P, M, K, N, S, H mamakisi). Iyo binder phase composition inonyanya kushandiswa pakusimba kwayo uye kusaita ngura.

Iyo matrix ye tungsten simbi ine zvikamu zviviri: chikamu chimwe chikamu chekuoma; chimwe chikamu isimbi yekubatanidza. Binder simbi dzinowanzo simbi dzeboka resimbi, dzinowanzo shandiswa cobalt uye nickel. Nokudaro, kune tungsten-cobalt alloys, tungsten-nickel alloys uye tungsten-titanium-cobalt alloys.

Kune simbi dzine tungsten, dzakadai sesimbi inomhanya-mhanya uye mamwe masimbi anopisa anopisa, tungsten yemukati musimbi inogona kuvandudza zvakanyanya kuomarara uye kupisa kupisa kwesimbi, asi kuomarara kunodonha zvakanyanya.

Iko kushandiswa kukuru kwe tungsten zviwanikwa zvakare yakasimbiswa carbide, kureva, tungsten simbi. Carbide, inozivikanwa semazino eindasitiri yemazuva ano, inoshandiswa zvakanyanya muzvigadzirwa zvesimbi tungsten.

Ingredient chimiro

Sintering process:

Sintering ye tungsten simbi ndeyekudzvanya hupfu mubillet, wobva wapinda muchoto chekupisa kuti upise kune imwe tembiricha (sintering tembiricha), chengeta kwenguva yakati (kubata nguva), wozoitonhodza pasi, kuti uwane. iyo tungsten simbi zvinhu zvine zvinhu zvinodiwa.

Matanho mana ekutanga e tungsten simbi sintering process:

1. Muchikamu chekubvisa chinoumba agent uye pre-sintering, sintered body inopinda zvinotevera shanduko panguva ino:

Kubviswa kweiyo molding agent, pamwe nekuwedzera kwekushisa muchikamu chekutanga chekupisa, iyo yekuumba inopera zvishoma nezvishoma kana kunyura, uye muviri wakasvibiswa unobviswa. Mhando, huwandu uye sintering maitiro akasiyana.

Maokisi ari pamusoro pehupfu anoderedzwa. Pakupisa kwekushisa, hydrogen inogona kuderedza maokisi e cobalt uye tungsten. Kana iyo inoumba agent ikabviswa muvacuum uye yakanyungudutswa, iyo carbon-oxygen reaction haina kusimba. Kushushikana kwekubatana pakati pezvimedu zvehupfu kunobviswa zvishoma nezvishoma, iyo yekubatanidza simbi poda inotanga kupora uye kudzokorora, kupararira kwepamusoro kunotanga kuitika, uye kusimba kwebriquetting kunovandudzwa.

2. Solid phase sintering stage (800℃——eutectic tembiricha)

Pakupisa kusati kwaonekwa kwechikamu chemvura, kunze kwekuenderera mberi kwechikamu chekare, iyo yakasimba-chikamu chekuita uye kupararira kunowedzerwa, kuyerera kwepurasitiki kunowedzerwa, uye muviri wakasvibiswa unoderera zvakanyanya.

3. Liquid phase sintering stage (eutectic tembiricha - sintering tembiricha)

Kana chikamu chemvura chikaonekwa mumuviri wakanyoroveswa, iyo shrinkage inopedzwa nekukurumidza, ichiteverwa necrystallographic shanduko kuumba iyo yekutanga chimiro uye chimiro cheiyo alloy.

4. Kutonhora nhanho (sintering tembiricha - kamuri tembiricha)

Panguva ino, chimiro uye chikamu chekuumbwa kwetungsten simbi ine dzimwe shanduko nemamiriro ekutonhora akasiyana. Iyi ficha inogona kushandiswa kupisa-trench tungsten simbi kuti ivandudze yayo yemuviri uye yemagetsi zvimiro.

Sumo yekushandisa

Tungsten simbi ndeye simende carbide, inozivikanwawo se tungsten-titanium alloy. Iko kuoma kunogona kusvika 89 ~ 95HRA. Nekuda kweizvi, tungsten simbi zvigadzirwa (zvakajairwa tungsten simbi wachi) hazvisi nyore kupfeka, zvakaoma uye kwete kutya annealing, asi brittle.

Zvikamu zvikuru zvesimende carbide ndeye tungsten carbide uye cobalt, iyo inotora 99% yezvikamu zvose, uye 1% ndiyo mamwe masimbi, saka inonziwo tungsten simbi.

Inowanzo shandiswa mumhando yepamusoro-chaiyo machining, yakakwirira-chaiyo maturusi emidziyo, lathes, kukanganisa drill bits, girazi cutter bits, tile cutters, yakaoma uye isingatyi annealing, asi brittle. Ndeyesimbi isingawanzoitiki.

Tungsten simbi (tungsten carbide) ine nhevedzano yezvivakwa zvakanakisa senge kuomarara kwakanyanya, kupfeka kuramba, simba rakanaka uye kuomarara, kupisa kupisa uye kusaita ngura, kunyanya kuomarara kwayo uye kupfeka kuramba, kunyangwe patembiricha ye500 ℃. Iyo inoramba isingachinjiki, uye ichine kuomarara kwakanyanya pa1000 ° C. Carbide inoshandiswa zvakanyanya sechinhu, senge maturusi ekushandura, milling cutters, mapurani, madhiri, maturusi anofinha, nezvimwewo, yekucheka simbi yakakandwa, isiri-ferrous simbi, mapurasitiki, kemikari fiber, graphite, girazi, dombo nesimbi yakajairika, uye inogona kushandiswawo kucheka simbi isingachinji. Zvakaoma-ku-muchina zvinhu zvakadai sesimbi inopisa, simbi isina tsvina, yakakwirira manganese simbi, simbi yemidziyo, nezvimwewo. Kucheka kwekucheka kwecarbide itsva yesimende kunosvika mazana emazana e carbon steel.

Tungsten simbi (tungsten carbide) inogona zvakare kushandiswa kugadzira maturusi ekuchera matombo, maturusi emigodhi, maturusi ekuchera, maturusi ekuyeresa, maturusi asingapfeki, simbi abrasives, humburumbira linings, precision bearings, nozzles, nezvimwe.

Kuenzanisa tungsten simbi mamakisi: 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 YL00 YG12 YL10 YG20 YG25 YG28YT5 YT14 YT15 P10 P20 M10 M20 M30 M40 V10 V20 V30 V40 Z01 Z10 Z20 Z30

Tungsten simbi, simende mapanga ecarbide, uye akasiyana tungsten carbide akajairwa masisitimu ane hombe hemesheni, uye ma blanks anowanikwa kubva kustock.
