Ke hāʻule ka pauma hydraulic i loko o kahi ʻaila ʻaila waho—a i ʻole e hopu ʻia kahi pahu winch i loko o kahi ʻeli eli—ʻaʻole hiki ke hoʻolālā ʻia ke kumu kumu. He lole. A ʻaʻole ʻaʻahu wale nō: micro-abrasion, galling, thermal fatigue ma lalo o 300°C cyclic load. Ma laila ʻO Stellite 6 ʻāpana hale hana pau ka hiki ke koho. E lilo ia i mea ʻokoʻa ma waena o 8,000 mau hola o ka lawelawe a me ka hemahema o ka mahina ʻai.
Ua hoʻolei mākou i nā nozzles Stellite 6 no nā ʻōnaehana hoʻoheheʻe waika kiʻekiʻe ma Saudi Arabia-a nānā iā lākou ma mua o ʻekolu mau hanauna o nā pani pani kulika maʻamau. Ua hana mākou i ka AMS 5387 piston pump cylinder housings no German OEMs e koi ana i ± 0.015 mm ka poepoe ma 200 mm anawaena, me ka hoʻopau ʻana i ka ʻili Ra ≤0.4 µm ma hope o ka wili hope ʻana. ʻAʻole kēia mau hiʻohiʻona theoretical. ʻO lākou nā hōʻailona i kēlā me kēia lā i kā mākou ʻoihana hoʻokumu ʻia a me ka mīkini hana ma Qingdao.
ʻAʻole ʻo Stellite 6 "he mea hoʻohui cobalt wale nō." ʻO kona haku mele—ma kahi o 65% Co, 28% Cr, 4% W, a me Ni, Fe, a me C—e hana ana i ka matrix o ka chromium carbide paʻakikī i hoʻokomo ʻia i loko o kahi ʻoluʻolu paʻa kobalt. Hāʻawi ia i ke kūpaʻa like ʻole i ka hoʻoheheʻe ʻana i ka metala-a-metala, ka ʻino i loko o nā kaiapuni waiwai chloride, a me ka hoʻomaʻamaʻa wela a hiki i 500°C. Eia naʻe ka mea e nānā ʻole ai ka hapa nui o nā mea kūʻai: ʻO ka hoʻolei ʻana iā Stellite 6 ʻaʻole like me ka hoʻolei kila. ʻO kona wahi hoʻoheheʻe kiʻekiʻe (1,290–1,350 ° C), haʻahaʻa ka wai, a me ka hoʻohaʻahaʻa loa e koi i ka gating kūikawā, ka hoʻomalu preheat mold, a me ka hoʻomaʻamaʻa ʻana i ka wela homogenization post-cast. Holo i kekahi ʻanuʻu—a loaʻa iā ʻoe ka porosity, ka hoʻokaʻawale carbide, a i ʻole nā pae interdendritic brittle. Ua ʻike mākou i ka hōʻole ʻana o nā mea kūʻai aku i ka 40% o ka hoʻolei ʻana i ka hui mua mai nā mea hoʻolako ʻole. He 92%+ ka nui o kā mākou hoʻoulu ʻana i nā mea hoʻokele waiwai Stellite 6 no ka mea ke kāohi nei mākou i nā ʻano like ʻole: ka palapala hōʻoia maka (nā mea hoʻoheheʻe kobalt T800-grade a pau i hiki ke ʻike ʻia i nā hōʻike hoʻāʻo wili), hoʻoheheʻe ʻia i ka ingot sourcing, a me ka hoʻomaʻamaʻa wela manawa maoli i ka wā paʻa.
Hoʻokaʻawale ʻo Vertical integration i nā ʻāpana Stellite 6 pono mai nā mea kūʻai aku. Ma QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., hana ʻia ka hoʻolei ʻana, CNC machining, a me ka hoʻopau ʻana ma lalo o hoʻokahi hale - me ka metrology like, ka unuhi ʻana o GD&T, a me ka hoʻopaneʻe lima ʻole. Ke hoʻouna ka mea kūʻai i kiʻi kiʻi no kahi plug cobalt alloy maʻamau me nā asymmetric cooling channel a me ka 0.008 mm kūlana hoʻomanawanui ma nā hiʻohiʻona ʻelima, ʻaʻole mākou e hoʻokuʻu i ka huli ʻana. Holo mākou iā ia ma kā mākou 5-axis DMG MORI NTX 1000, me ka hoʻohana ʻana i nā mea hana PCD-tipped i hoʻopaʻa ʻia no nā alloy cobalt, me ka hoʻāʻo ʻana i ka laser e hōʻoia i ka mānoanoa o ka pā ma mua o ka wili ʻana i ka ID hope. ʻAʻohe mea kūʻai waho i hoʻomaopopo i ka hopena o ke koʻikoʻi o ka hoʻolei ʻana i ka distortion machining ma ke kino valve 320 mm lōʻihi. Hana mākou—no ka mea, hoʻolei mākou, mālama wela, mīkini, a nānā iā ia me ka papahana CMM like mai ka hoʻomaka a i ka pau.
ʻO ka hana honua maoli e pili ana i ʻekolu mau mea kūʻai ʻole-ʻaʻole nā koi kūʻai. mua: kūlike mau mea. Loaʻa kēlā me kēia ʻāpana Stellite 6 i ka loiloi spectrographic, ka palapala ʻāina paʻakikī ma waena o nā ʻāpana, a me ka hōʻoia ʻana i ka nui o ka palaoa ASTM E112. ʻElua: manaʻo kūpaʻa. Hoʻopaʻa mākou i nā ʻaoʻao koʻikoʻi me ka hoʻohana ʻana i nā profilometer optical-ʻaʻole wale i nā CMMs-e hopu i ka micro-topography e pili ana i ka pono o ka sila. ʻEkolu: hōʻoia hana. Ma mua o ka hoʻouna ʻana, e hoʻāʻo ʻia kēlā me kēia puʻu kaomi hydrostatic i ka 1.5x helu ʻana i ke kaomi hana; Hoʻopaʻa ʻia kēlā me kēia hale pahū me ka helium mass spectrometry. ʻAʻole noi nā mea kūʻai ma ʻAmelika ʻĀkau a me ʻEulopa i nā palapala hōʻoia - noi lākou i nā hōʻike hoʻāʻo kikoʻī kikoʻī me nā timestamp, ID operator, a me nā peʻa calibration lako. Hāʻawi mākou iā lākou.
Inā pili kāu noi i nā slurries abrasive, ka mahu wela kiʻekiʻe, a i ʻole ka hoʻouka ʻana ma luna o 200 MPa, ʻaʻole ʻo Stellite 6 ka hana ʻenehana. He ʻinikua. Akā, hana wale ka ʻinikua inā loaʻa i ka mea hāʻawi ka ʻike - ʻaʻole wale nā brochures. E ʻimi i ka kūleʻa i kākau ʻia ma kāu ʻāpana: nā hui pauma no nā noi ma lalo o ka moana, nā wili pahu winch center shaft no nā cranes kaumaha, a i ʻole nā nozzles cobalt alloy no nā mea kanu desalination. E nānā inā paʻa lākou i nā ʻae kaʻina hana AMS 5387—ʻaʻole nā palapala hōʻoia waiwai wale nō. E hōʻoia inā loaʻa i kā lākou mau moʻolelo maikaʻi ke ʻike piha i ka helu wela o ka cobalt ingot. A laila e hoʻohālikelike i ke aʻo ʻana: hiki iā lākou ke hoʻopaʻa i nā puka makani ± 3 lā ma nā kauoha medium-volume me ka ʻole o ka uku wikiwiki? ʻO ia ka pūlima o kahi ʻoiaʻiʻo ʻO Stellite 6 ʻāpana hale hana-ʻaʻole kahi hale kūʻai hana me ka ʻikepili kobalt alloy.
