Mea hoʻoheheʻe wai pauka hao no nā metala makamae gula kālā keleawe

Nui nō nā hemahema i ka hoʻomaopopo ʻana i ka ʻenehana paʻi 3D ma nā ʻano āpau o ka ʻoihana hana o Kina. Ma muli o ke kūlana hoʻomohala maoli, ʻaʻole i hoʻokō ka paʻi 3D i ka ʻoihana makua, mai nā lako a i nā huahana a i nā lawelawe aia nō i ke kahua "mea pāʻani holomua". Eia nō naʻe, mai ke aupuni a i nā ʻoihana ma Kina, ua ʻike nui ʻia nā manaʻolana hoʻomohala o ka ʻenehana paʻi 3D, a nānā nui ke aupuni a me ke kaiāulu i ka hopena o ka ʻenehana lako hana pulverizing metala paʻi 3D e hiki mai ana ma nā hiʻohiʻona hana, hoʻokele waiwai, a me ka hana ʻana o koʻu ʻāina.

Wahi a ka ʻikepili noiʻi, i kēia manawa, ʻaʻole i kālele ʻia ke koi o koʻu ʻāina no ka ʻenehana paʻi 3D ma nā lako, akā ua ʻike ʻia i loko o nā ʻano mea hoʻopau paʻi 3D a me ke koi no nā lawelawe hana ʻoihana. ʻO nā mea kūʻai aku ʻoihana ke kumu nui o ke kūʻai ʻana i nā lako paʻi 3D ma koʻu ʻāina. Hoʻohana nui ʻia nā lako a lākou e kūʻai ai i ka mokulele, aerospace, nā huahana uila, ka halihali, ka hoʻolālā, ka hana noʻeau moʻomeheu a me nā ʻoihana ʻē aʻe. I kēia manawa, ʻo ka hiki ke hoʻokomo ʻia o nā mīkini paʻi 3D ma nā ʻoihana Kina ma kahi o 500, a ʻo ka piʻi ʻana o ka makahiki ma kahi o 60%. Eia naʻe, ʻo ka nui o ka mākeke o kēia manawa ma kahi o 100 miliona yuan i kēlā me kēia makahiki. Ua hiki aku ka makemake no ka R&D a me ka hana ʻana i nā mea paʻi 3D i kahi kokoke i 1 biliona yuan i kēlā me kēia makahiki. Me ka hoʻolaha ʻana a me ka holomua o ka ʻenehana lako, e ulu wikiwiki ka unahi. I ka manawa like, ua kaulana loa nā lawelawe hana i hilinaʻi ʻia e pili ana i ka paʻi 3D, a he nui nā ʻelele o ka ʻoihana lako paʻi 3D i oʻo loa i ke kaʻina hana sintering laser a me ka hoʻohana ʻana i nā lako, a hiki ke hāʻawi i nā lawelawe hana waho. ʻOiai ʻoi aku ke kumukūʻai o hoʻokahi lako ma mua o 5 miliona yuan, ʻaʻole kiʻekiʻe ka ʻae ʻia ʻana e ka mākeke, akā kaulana loa ka lawelawe hana ʻoihana.

ʻO ka hapa nui o nā mea i hoʻohana ʻia i nā lako hana pulverizing metala paʻi 3D o koʻu ʻāina e hāʻawi pololei ʻia e nā mea hana prototyping wikiwiki, a ʻaʻole i hoʻokō ʻia ka lako o nā mea maʻamau mai ka ʻaoʻao ʻekolu, e hopena ana i nā kumukūʻai mea kiʻekiʻe loa. I ka manawa like, ʻaʻohe noiʻi e pili ana i ka hoʻomākaukau ʻana i ka pauka i hoʻolaʻa ʻia no ka paʻi 3D ma Kina, a aia nā koi koʻikoʻi no ka hoʻolaha ʻana o ka nui o nā ʻāpana a me ka nui o ka oxygen. Hoʻohana kekahi mau ʻāpana i ka pauka pīpī maʻamau, kahi he nui nā mea hiki ʻole ke hoʻohana.

ʻO ka hoʻomohala ʻana a me ka hana ʻana i nā mea hana ʻoi aku ka maʻalahi ke kī i ka holomua ʻenehana. ʻO ka hoʻoponopono ʻana i nā pilikia hana a me ke kumukūʻai o nā mea e hoʻolaha maikaʻi aku i ka hoʻomohala ʻana o ka ʻenehana prototyping wikiwiki ma Kina. I kēia manawa, ʻo ka hapa nui o nā mea i hoʻohana ʻia i ka ʻenehana prototyping wikiwiki paʻi 3D o koʻu ʻāina e pono e lawe ʻia mai nā ʻāina ʻē, a i ʻole ua hoʻokomo nā mea hana lako i ka nui o ka ikehu a me ke kālā e hoʻomohala iā lākou, he pipiʻi, e hopena ana i ka hoʻonui ʻia o nā kumukūʻai hana, ʻoiai ʻo nā mea kūloko i hoʻohana ʻia i kēia mīkini he haʻahaʻa ka ikaika a me ka pololei. . He mea nui ka localization o nā mea paʻi 3D.

Pono nā pauka titanium a me ka titanium alloy a i ʻole nā ​​pauka superalloy nickel a me cobalt me ​​ka haʻahaʻa o ka oxygen, ka nui o nā ʻāpana maikaʻi a me ke ʻano sphericity kiʻekiʻe. ʻO ka nui o ka pauka ʻāpana he -500 mesh nui, pono e emi ka oxygen ma mua o 0.1%, a like ka nui o nā ʻāpana. I kēia manawa, hilinaʻi nui nā mea hana pauka alloy kiʻekiʻe a me nā lako hana i nā mea lawe mai. Ma nā ʻāina ʻē, hoʻopili pinepine ʻia nā mea maka a me nā lako e loaʻa ai ka nui o ka loaʻa kālā. Ke lawe nei i ka pauka nickel ma ke ʻano he laʻana, ʻo ke kumukūʻai o nā mea maka ma kahi o 200 yuan/kg, ʻo ke kumukūʻai o nā huahana kūloko maʻamau he 300-400 yuan/kg, a ʻoi aku ke kumukūʻai o ka pauka lawe mai ma mua o 800 yuan/kg.

No ka laʻana, ka mana a me ka hiki ke hoʻololi i ka haku mele ʻana o ka pauka, nā hoʻokomo ʻana a me nā waiwai kino ma nā ʻenehana pili o nā lako wili pauka atomization metala paʻi 3D. No laila, i ka nānā ʻana i nā koi hoʻohana o ka haʻahaʻa o ka oxygen a me ka pauka nui o ka ʻāpana liʻiliʻi, pono nō e hana i nā hana noiʻi e like me ka hoʻolālā haku mele ʻana o ka pauka titanium a me ka titanium alloy, ka ʻenehana wili pauka atomization gas o ka pauka nui o ka ʻāpana liʻiliʻi, a me ka mana o nā ʻano pauka ma ka hana huahana. Ma muli o ka palena o ka ʻenehana wili ma Kina, he paʻakikī ke hoʻomākaukau i ka pauka maikaʻi i kēia manawa, haʻahaʻa ka hua pauka, a kiʻekiʻe ka nui o ka oxygen a me nā haumia ʻē aʻe. I ka wā o ke kaʻina hana hoʻohana, ua maʻalahi ke kūlana hoʻoheheʻe pauka i ka like ʻole, e hopena ana i ka nui o nā hoʻokomo oxide a me nā huahana denser i loko o ka huahana. ʻO nā pilikia nui o nā pauka alloy kūloko i ka maikaʻi o ka huahana a me ke kūpaʻa o ka batch, me: ① kūpaʻa o nā ʻāpana pauka (helu o nā hoʻokomo, like o nā ʻāpana); ② kino pauka Paʻa o ka hana (ka hoʻolaha nui o ka ʻāpana, ke ʻano o ka pauka, ka wai, ka lakio wehe, a pēlā aku); ③ pilikia o ka hua (haʻahaʻa ka hua o ka pauka ma ka ʻāpana nui o ka ʻāpana haiki), etc.
