He aha te mea nui o te tungsten mō ngā mahi keri hinu me te hau?

Ko te hiranga o te tungsten (ina koa ko te tungsten carbide) i roto i te keri hinu ka taea te whakarite ki tōna hiranga"Ngā niho ahumahi"o te mahi. Ka whakaratohia e ia ngā taputapu keri me tete kaha ki te pakaru tonu, te whai hua, me te pono o te toka, me te tiaki anō i a rātou anō i raro i ngā āhuatanga whenua tino kino. Tēneihe huinga tino pai o te pakeke, te pakari, te ātete ki te pāmahana teitei, me te ātete ki te kakahuhe mea tino nui tēnei rauemi rautaki, ā, he mea kāore e taea te whakakapi i tēnei wā. Koinei anō te take e pā tika ana ngā piki me ngā heke o ngā utu o te tungsten ki te umanga keri hinu katoa.

Kei raro nei he tātaritanga taipitopito o ngā take matua:

I. He Rauemi Matua mō te Whakakore i ngā Āhuatanga Whakahaere Tino Kino

E toru ngā wero "tino nui" e pā ana ki te keri hinu—ina koa i roto i ngā puna hohonu, ngā puna tino hohonu, ngā puna whakapae hau kirikiri, me te keri moana:

1. Te Pēhanga Tino Nui me te MahanaI ngā hōhonutanga o ētahi kiromita, ka taea e te pāmahana te neke ake i te 200°C, me te pēhanga e eke ki ngā rau o ngā āhuarangi.
2. Te Whakakorenga Tino NuiMe pakaru ngā mata keri i roto i ngā hanganga mārō me ngā hanganga whakakoi (hei tauira, te karāneti, te kiripaka, te kirikiri kirikiri kuata).
3. Te Waikura Tino NuiTērā pea kei roto i ngā wai keri ngā matū waikura, te tote, me te hau hauwai whanariki.

Otinga a te Tungsten: Koranu Mārō o te Tungsten Carbide

• Te Pakari me te Ātete ki te MauKo te tungsten carbide te tuarua o ngā mea pakeke i muri i te taimana, engari he nui ake te ātete ki ngā pānga me te pakari ki te taimana. Mā tēnei ka taea e ia te mahi pērā i ngā "niho ahumahi", te tapahi tonu i te toka i raro i te hurihanga tere me te kawenga taimaha, me te roa o te ora mahi tekau ki te rau ngā wā i te maitai noa.
• Pakari Wera Tino PaiKa mau tonu tōna mārō ahakoa i ngā pāmahana teitei (tae atu ki te ~1000°C), he rerekē ki te nuinga o ngā konganuku e tere whakangawari ana, e pakaru ana hoki.
• Te Pūmautanga Matū PaiKa ātete ki te waikura mai i ngā wai keri me ngā wai o raro whenua.

II. Ngā Whakamahinga Matua i roto i ngā Pūnaha Keri

He mea nui te tungsten (ko te nuinga he tungsten carbide me ngā koranu tungsten) ki ngā āhuatanga maha o ngā mahi keri:

1. Ngā "Niho" me ngā Tapa Tapahi o ngā Mata Wiri:

• Ngā Momo KōneKo ngā "niho" kua whakauruhia ki roto i ia koeko he mea hanga te nuinga ki te tungsten carbide. Koinei te rārangi mua i te pa atu me te pakaru o te toka.
• Ngā Momo Tapahi-WhakapūmauAhakoa e whakamahia ana e ngā mata PDC (Polycrystalline Diamond Compact) ngā taputapu tapahi taimana mō te kutikuti i ngā wāhi whānui,ngā kutikuti ine, ngā niho rekereke, me ngā whakaurunga whakakaha i ngā wāhi tino nuihe maha ngā wā ka whakawhirinaki ki te tungsten carbide hei ārai i te kakahu o te tinana o te moka.
• Ngā Wāhanga MotuhakeKo ngā "Mata Taimana Whakakīia" e whakamahia ana i roto i ngā hanganga tino mārō he nui ngā matūriki tungsten carbide kei roto i te anga, e mahi ana hei rauemi whakakoi me te hanganga tautoko.

1. Ngā Wāhanga Ātete-Kakahu mō ngā Utauta Hira:

• Ngā Utauta o raro i te PōkaKo ngā mata o waho o ngā taputapu MWD/LWD, ngā mea whakau, me ngā mea whakakīia he mata mārō ki ngā matūriki tungsten carbide, he mea whakapaipai rānei ki ngā whakaurunga tungsten carbide hei ārai i te pakaru kino o te poka.
• Ngā Wāhanga Aho WiriKua pania ngā whitiki mau o ngā hononga taputapu paipa wiri me ngā paipa wiri taumaha ki te tungsten carbide hei whakaiti i te waku me te mau ki te anga, hei tiaki i ngā ngongo utu nui.

1. Rauemi Taumaha Matotoru-Teitei:

• Ngā koranu Tungsten-nickel-rinoe whakamahia ana mō ngā taumaha i roto i ngā taputapu tuhi tika pērā i te MWD/LWD. Ā rātoukiato teitei (≈18 g/cm³)ka taea te pupuri i te nui o te papatipu i roto i ngā wāhi kuiti, ka pumau ai ngā taputapu, ā, ka tika ai te kohikohi raraunga.

III. Ngā Painga Tika—He aha i "Kāore e taea te Whakakapi"

1. Te Whai Huatanga o te Keri: Ko ngā wāhanga tungsten pakeke ake, ātete ki te kakahu ka hua akengā reiti urunga teitei ake (ROP)mehe roa ake te kiriata mō ia oma moka, ka whakaiti tika i te wā hanga poka.
2. Te Haumaru me te Pono o te Whakahaere kua WhakapūmautiaMā te pakaru ohorere o tētahi mata, o tētahi taputapu rānei i roto i ngā mano mita te hohonu o te poka ka hua ake he mahi hī ika utu nui, ka ngaro rānei te puna. Ko te pono tino pai o ngā wāhanga tungsten te mea nui ki te haere tonu o te mahi.
3. Te Utu Katoa ItiAhakoa he utu nui ngā rauemi tungsten, ko ngā painga—te wā pakaru kua whakaitihia mō ngā whakarerekētanga moka, ngā reiti rahunga iti iho, me te tapeke o ngā pikitia keri teitei ake—ka tino iti ake te utu mō ia mita puta noa i te huringa ora katoa.
4. Whakahohe i ngā Mahi Tino KahaKi te kore he koranu mārō e ahu mai ana i te tungsten, kāore e taea te keri i ngā puna o ēnei rā neke atu i te 5,000 mita te hohonu (ngā puna hōhonu/tino hōhonu) me ngā āhuahanga puna uaua i runga i te hangarau, i te ōhanga rānei.
