Ma ka lā 20 o Dekemaba, ua ʻike ka mea kākau moʻolelo mai ka China Iron and Steel Research Group Gaona Company ua alakaʻi ka ʻoihana i ka hana pū ʻana iā Fushun Special Steel lāua ʻo Erzhong Wanhang no ka manawa mua i nā lā i hala iho nei e hoʻāʻo pono ai i ka hana ʻana i ka superalloy turbine disk integral die forging nui loa ma koʻu ʻāina i kēia manawa—— ʻO nā super-large GH4706 alloy turbine disk forgings, kūpono no ka hoʻohana ʻana ma lalo o nā kūlana mahana kiʻekiʻe o 650 degere Celsius, me ka pae ikaika o 1200 MPa, ke kaumaha o 13.5 tons, a me ke anawaena o 2380 mm, ua uhaʻi i ka monopoly haole.
Wahi a Zhao Guangpu, ke alakaʻi o ka papahana noiʻi a me ka hope luna hoʻokele o ke Komite ʻEpekema a me ka ʻenehana Noiʻi kila Gona, he mau pono koʻikoʻi ko nā turbine kinoea hana kaumaha no nā kikowaena mana nui e like me ka mana kiʻekiʻe, ka pono wela kiʻekiʻe, ka liʻiliʻi o ka nui a me ke kaumaha, a me ka haumia haʻahaʻa. Ua lilo kāna ʻenehana hana i pae ʻenehana aupuni. , ʻO kekahi o nā hōʻailona koʻikoʻi o ka ikaika aupuni piha. ʻO kāna mau ʻāpana wela nui he hoʻokahi disc a ʻelua (nā disc turbine a me nā alakaʻi, nā pahi hana), e hana ana ma ke ʻano he "puʻuwai" o ke kanaka. ʻO lākou ke ʻenehana koʻikoʻi no ka hana ʻana i nā turbine kinoea a me ka bottleneck e kaupalena ana i ka localization o nā turbine kinoea kaumaha. Pono nā disks turbine turbine kinoea hana kaumaha ma mua o 100,000 mau hola o ka lawelawe wela kiʻekiʻe a me ke kaumaha kiʻekiʻe, a koi i ke ʻano metallurgical kiʻekiʻe loa o nā mea, e like me ka homogeneous, maʻemaʻe, fine-grained, paʻa ka hoʻonohonoho a me ka hana o nā mea; ʻoi aku ka nui o ka nui, a ʻo kona anawaena a me ka wahi hoʻolele he ʻoi aku ia ma mua o 2.2 mika a me 4.2 mika kuea, ʻo ia hoʻi he 4 manawa ke anawaena o ka disk turbine aero engine, 10 manawa ke anawaena i hoʻolele ʻia, a me 60 manawa ke kaumaha, a pēlā aku. ʻO ka ʻenehana hana hana koʻikoʻi o nā disk turbine super-sized ua paʻa loa i nā ʻāina ʻē a ua hoʻopaʻa ʻia e nā ʻāina Komohana no ka manawa lōʻihi.
No kēia hopena, ua alakaʻi ʻo Zhao Guangpu i ka hui papahana e hoʻokō i kahi moʻo o ka noiʻi kumu a me ka noiʻi ʻenehana, a ma ka hope loa ua hoʻohana i ka ʻenehana hoʻomākaukau "triple smelting + repeated upsetting + twice upsetting + one-fire overall die forging" honua holomua loa e hoʻokō i nā Kūlana honua, e uhaʻi ana i ka bottleneck loea o ka hoʻomākaukau ʻana o ka disk turbine superalloy nui i loaʻa i ka wā o ke kaʻina hana hoʻomohala, e like me ka ʻenehana hoʻoheheʻe haʻahaʻa triple no nā ingots kila nui me nā ingots i kaupaona ʻia ma mua o 18 tons, a me ka ʻenehana upsetting hou a me ka fine-grain blooming no nā kaola nui me ke anawaena o 1000 mm, me ke anawaena o 2200 Integral die forging a me ka hana haʻahaʻa-mahana a me ka hoʻonohonoho ʻana i ka ʻenehana no nā ʻāpana pā nui i ʻoi aku ma mua o millimeters. Ua hana ka hui papahana i ka noiʻi kūʻokoʻa a me ka hoʻomohala a me ka hana hou mua no nā hemahema metallurgical e like me ka nui o ka Nb o ka element alloying i loko o ka GH4706 superalloy, kahi i maʻalahi i nā kiko ʻeleʻele a me ka hoʻokaʻawale kiko keʻokeʻo. ʻO nā ʻāpana koʻikoʻi o nā turbine kinoea kaumaha o koʻu ʻāina ʻo ia ka "ʻāʻī paʻa", ka mea i wehe i kahi ala hana no ka hoʻomākaukau ʻana i nā disks turbine superalloy deformed nui me nā ʻano Kina me nā kuleana waiwai kūʻokoʻa.
Ma hope o ke anatomy, ua hōʻea ka hana o ka disc turbine i nā koi kuhikuhi loea o nā alloys haole like, a ua hoʻokō ʻia kahi hopena milestone. ʻO kēia kekahi holomua koʻikoʻi a koʻu ʻāina i hana ai ma ke kahua o nā superalloys deformed, ka mea i hoʻokele i ka ʻenehana hoʻomākaukau o nā disks turbine super-large kūloko e hōʻea i ka pae alakaʻi honua. Ma ka lā 8 o Dekemaba, ua mālama ʻia ka hālāwai loiloi node milestone no GH4706 alloy full-size roulette forgings ma Beijing. Ua hāʻawi nā loea i kahi loiloi kiʻekiʻe, ʻo ia hoʻi ua lawe ʻia kahi ʻanuʻu paʻa i ka hoʻohana maoli ʻana i ka disk turbine.
