Simbi yeTungsten (tungsten carbide) ine zvinhu zvakawanda zvakanaka zvakaita sekuomarara kwakanyanya, kusakara, kusimba uye kusimba, kusapisa uye kuramba ngura, kunyanya kuomarara kwayo kwakanyanya uye kusakara, kunyangwe patembiricha ye500 ℃. Inoramba isina kuchinja, uye ichiri nekuomarara kwakanyanya pa1000 °C.

Zita rechiChinese: simbi ye tungsten

Zita rekunze: Zita rekuti Cemented Carbide

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

Zvigadzirwa: Tsvimbo yakatenderera, ndiro yesimbi ye tungsten

Nhanganyaya:

Simbi yeTungsten, inozivikanwawo secemented carbide, inoreva zvinhu zvakasanganiswa zvine kanenge kabhayidhi yesimbi imwe chete. Tungsten carbide, cobalt carbide, niobium carbide, titanium carbide, uye tantalum carbide zvinhu zvakajairika zvesimbi yetungsten. Saizi yezvikamu zvecarbide (kana phase) inowanzo kuva pakati pe 0.2-10 microns, uye tsanga dzecarbide dzinobatanidzwa pamwe chete uchishandisa metallic binder. Binder inowanzoreva metal cobalt (Co), asi kune mamwe mashandisirwo akakosha, nickel (Ni), iron (Fe), kana dzimwe simbi uye alloys zvinogonawo kushandiswa. Musanganiswa wezvikamu zvecarbide ne binder phase unotsanangurwa unonzi "grade".

Kurongwa kwesimbi yetungsten kunoitwa zvichienderana neISO standards. Kurongwa uku kunoenderana nerudzi rwechinhu chebasa (senge P, M, K, N, S, H grades). Musanganiswa wechikamu chebinder unonyanya kushandiswa nekuda kwesimba rayo uye kuramba kwayo ngura.

Matrix yesimbi ye tungsten ine zvikamu zviviri: chikamu chimwe chikamu chekuomesa; chimwe chikamu isimbi inobatanidza. Zvisimbi zvinosunga zvinowanzova simbi dzeboka resimbi, cobalt ne nickel dzinoshandiswa zvakanyanya. Nokudaro, kune tungsten-cobalt alloys, tungsten-nickel alloys uye tungsten-titanium-cobalt alloys.

Kune simbi dzine tungsten, dzakadai sesimbi inomhanya zvakanyanya uye dzimwe simbi dzinopisa, huwandu hwetungsten musimbi hunogona kuwedzera kuomarara uye kuramba kupisa kwesimbi, asi kuomarara kwayo kuchaderera zvakanyanya.

Kushandiswa kukuru kwezviwanikwa zvetungsten isimbi yakagadzirwa nesimende, kureva tungsten steel. Carbide, inozivikanwa semazino eindasitiri yemazuva ano, inoshandiswa zvakanyanya muzvigadzirwa zvesimbi yetungsten.

Chimiro chezvinhu zvirimo

Maitiro ekuchenesa:

Kupisa simbi ye tungsten zvinoreva kudzvanya upfu mu billet, wobva wapinda muchoto chinopisa kusvika patembiricha yakatarwa (kupisa kunodziya), wochichengeta kwenguva yakati (nguva inomira), wozochitonhodza, kuitira kuti simbi ye tungsten iwane hunhu hunodiwa.

Matanho mana ekutanga ekugadzira tungsten steel sintering:

1. Padanho rekubvisa chinhu chinoumba uye kupiswa kweganda, muviri wakacheneswa unosangana neshanduko dzinotevera padanho iri:

Kubviswa kwechinhu chinoumba, nekuwedzera kwekupisa pakutanga kwekusviba, chinhu chinoumba chinoora zvishoma nezvishoma kana kupwanyika, uye muviri unosviba unobviswa. Rudzi, huwandu uye maitiro ekusviba zvakasiyana.

Ma oxide ari pamusoro peupfu anodzikira. Pakupisa kwekusviba, hydrogen inogona kuderedza ma oxide e cobalt ne tungsten. Kana chinhu chinoumba chikabviswa mu vacuum uye chakasviba, carbon-oxygen reaction haina kusimba. Kusangana pakati pezvikamu zveupfu kunobviswa zvishoma nezvishoma, upfu hwesimbi hunobatana hunotanga kupora uye kudzokororwa, kupararira kwepasi kunotanga kuitika, uye simba re briquetting rinovandudzika.

2. Danho rekupisa chikamu chakasimba (800℃——tembiricha ye eutectic)

Pakupisa kusati kwaonekwa chikamu chemvura, pamusoro pekuenderera mberi kwekuita kwechikamu chekare, maitiro echikamu chakasimba uye kupararira zvinowedzerwa, kuyerera kwepurasitiki kunowedzerwa, uye muviri wakacheneswa unodzikira zvakanyanya.

3. Danho rekupisa mvura (tembiricha ye eutectic - tembiricha yekupisa)

Kana chikamu chemvura chikaonekwa mumuviri wakacheneswa, kupwanyika kwacho kunopera nekukurumidza, zvichiteverwa nekushandurwa kwekristalographic kuti kugadzire chimiro chekutanga uye chimiro chealloy.

4. Danho rekutonhodza (tembiricha yekudziya - tembiricha yemukamuri)

Padanho rino, chimiro uye chimiro chesimbi ye tungsten zvine shanduko dzakasiyana nemamiriro ekutonhodza. Chinhu ichi chinogona kushandiswa kupisa simbi ye tungsten kuti ivandudze hunhu hwayo hwepanyama uye hwemakanika.

Sumo yekushandisa

Simbi yeTungsten ndeye carbide yakagadzirwa nesimende, inozivikanwawo se tungsten-titanium alloy. Kuoma kwayo kunogona kusvika 89~95HRA. Nekuda kweizvi, zvigadzirwa zvesimbi yeTungsten (mawachi esimbi eTungsten akajairika) hazvisi nyore kupfeka, zvakaoma uye hazvityi kupwanywa, asi zvinopfava.

Zvikamu zvikuru zve carbide yakagadzirwa nesimende i tungsten carbide ne cobalt, izvo zvinoumba 99% yezvikamu zvese, uye 1% zvimwe simbi, saka inonziwo tungsten steel.

Inowanzoshandiswa mukugadzira zvinhu nemazvo, muzvinhu zvekushandisa nemazvo, mukugadzira machira, mukugadzira mabhora ekushandisa magirazi, mukugadzira mataira, mukugadzira machira akaomarara uye asingatyi kupwanywa, asi anopfava. Inoshandiswa musimbi isingawanzoonekwi.

Simbi yeTungsten (tungsten carbide) ine zvinhu zvakanaka zvakaita sekuomarara kwakanyanya, kusakara, simba rakanaka uye kusimba, kusapisa uye kusakara, kunyanya kuomarara kwayo kwakanyanya uye kusakara, kunyangwe patembiricha ye500 ℃. Inoramba isina kuchinja, uye ichiri nekuomarara kwakanyanya pa1000 °C. Carbide inoshandiswa zvakanyanya sechinhu, senge maturusi ekutenderedza, zvigayo zvekucheka, maplaner, madhiri, maturusi anoboorera, nezvimwewo, pakucheka simbi yakakandwa, simbi dzisina ferrous, mapurasitiki, mafiber emakemikari, graphite, girazi, matombo nesimbi yakajairika, uye inogonawo kushandiswa pakucheka simbi inodzivirira. Zvinhu zvakaoma kushandisa muchina zvakaita sesimbi inopisa, simbi isina ngura, simbi ine manganese akawanda, simbi yezvishandiso, nezvimwewo. Kumhanya kwekucheka kwecarbide itsva yakagadzirwa nesimende kwakapetwa kazana kupfuura simbi yekabhoni.

Simbi yeTungsten (tungsten carbide) inogona kushandiswawo kugadzira maturusi ekuboorera matombo, maturusi ekuchera, maturusi ekuboorera, maturusi ekuyera, zvikamu zvisingapfeki, zvinobvisa simbi, machubhu emasilinda, mabheringi ekugadzirisa, maburiro, nezvimwewo.
