Nā mea paʻa mahana kiʻekiʻe-- mālama i ka ikaika kiʻekiʻe ma lalo o nā mahana kiʻekiʻe
Nā Hiʻohiʻona Huahana
He kila kila hana kiʻekiʻe ke kila 7709, i ʻike ʻia hoʻi ʻo 21CrMoV5-7, a hoʻohana nui ʻia i ka hana ʻana i nā mea paʻa ikaika kiʻekiʻe, kūpaʻa i ka mahana kiʻekiʻe e like me nā bolts a me nā nati. Eia kahi hoʻolauna hohonu i nā wili i hana ʻia me ka mea 1.7709:
(1). Ka hoʻohuihui kemika: ʻO ke kumu nui o ia mea he kalapona (C: 0.17-0.25), silicon (Si: 0.15-0.35), manganese (Mn: 0.35-0.85), chromium (Cr: 1.20-1.50), molybdenum (Mo: 0.65-0.80), a me vanadium (V: 0.25-0.35) a me nā mea ʻē aʻe. ʻO ka hapa kūpono o kēia mau mea e hāʻawi i ke kila i nā waiwai piha maikaʻi loa.
(2). Nā waiwai mīkini: I ke kūlana i mālama ʻia me ka wela, loaʻa i ke kila 1.7709 ka ikaika kiʻekiʻe a me nā waiwai mechanical maikaʻi. Hiki i kona ikaika hua (Rp0.2) ke hiki i ka ≥550 MPa, hiki i ka ikaika tensile (PM) ke hiki i ka ≥700 MPa, elongation (A) ≥16%, a me ka hōʻemi ʻana o ka wahi (A) ≥60%.
(3). Ke kū'ē wela: Hiki i kēia mea ke mālama i nā waiwai mechanical maikaʻi i nā wahi wela kiʻekiʻe a kūpono hoʻi no nā kūlana hana me nā mahana ma mua o 300°C.
Noi
Pono nā mea paʻa wela kiʻekiʻe (HT HS Fasteners) e hoʻokō i nā koi e like me ka ikaika wela kiʻekiʻe, ka waiwai anti-rust a me ke kūpaʻa i ka corrosion i nā wahi koʻikoʻi. ʻO kā lākou mau kahua noi nui penei:
(1) Kahua mokulele
ʻEnekini aerospace: Hana ʻia nā mea hoʻopaʻa pahi turbine me ka hoʻohana ʻana i nā mea hoʻohuihui wela kiʻekiʻe e pili ana i ka nickel (e like me GH4049), e mālama ana i ka ikaika tensile o ≥ 1000 MPa ma 600 - 900 ℃, a me ka hoʻokō ʻana i ka hana ʻana i ke ʻano paʻakikī ma o ka ʻenehana make forging.
ʻAno o ka mokulele: Pono nā ʻāpana i hoʻohana ʻia no ka hoʻohui ʻana i ke keʻena kuni o ka ʻenekini rocket e kū i nā mahana kiʻekiʻe koke (>1200℃) a me nā ukana haʻalulu.
(2) ʻOihana Ikehu a me ka Mana
Hale hana mana nukelea: Pono nā ʻūmiʻi o ka ipu kaomi reactor e kū i ka ikaika mau loa o ≥ 95 MPa (ma 700°C/100,000 hola), i mea e pale ai i ka hydrogen embrittlement a me ka nahā ʻana o ka stress corrosion.
ʻO ka turbine kinoea: Hoʻohana ʻia nā wili wela kiʻekiʻe (e like me ke kola A286) e hoʻopaʻa i nā disc turbine a pono e hana i nā hoʻokolohua palena kolo (1% total deformation / 1000 hola)
(3) ʻOihana Kemika ʻAila a me ke ʻenekinia moana
ʻĀpana hoʻomaʻemaʻe a me ka hana ʻana: Pono e hoʻohana ʻia nā ʻōwili o ka reactor hydrogenation no ka manawa lōʻihi ma lalo o ke kiʻekiʻe o ka mahana a me ke kaomi kiʻekiʻe (400 ℃ / 20MPa), a pono e hala ka mea i ka hoʻāʻo haki lohi i hoʻokomo ʻia e ka hydrogen.
(4) Ke kau ʻana ma ke ʻano kalepa
Hana ʻana i ka ʻōmole: Pono nā ʻāpana hoʻopaʻa o nā ʻōmole mea hui e kūlike me kahi coefficient hoʻonui wela haʻahaʻa (CTE ≤ 10⁻⁶/℃) e mālama i ke kūpaʻa o ka dimensional.
(5) Nā kaʻa a me ke kaʻaahi
Nā kaʻa ikehu hou: Hana ʻia nā ʻūmiʻi o ke koʻokoʻo kaʻa me ka titanium alloy (e like me TC4), me ka ikaika tensile a hiki i ka 900 MPa a ʻaʻohe mea hoʻopilikia magnetic. Pono e hoʻomaikaʻi ʻia ke kaʻina hana tapping e hōʻemi i ka paʻakikī o ka hana.
Eia nā ʻano nui o nā mea hoʻopaʻa wela kiʻekiʻe
