Ma ka lā 20 o Dekemaba, ua aʻo ka mea kākau moʻolelo mai ka China Iron and Steel Research Group Gaona Company ua alakaʻi ka hui i ka hana pū ʻana o Fushun Special Steel a me Erzhong Wanhang no ka manawa mua i nā lā i hala aku nei e hoʻāʻo maikaʻi-hana i ka superalloy turbine disk integral. make forging ma koʻu ʻāina i kēia manawa—— ʻO ka GH4706 alloy turbine disk forgings nui loa, kūpono no ka hoʻohana ʻana ma lalo o nā kūlana wela 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, nahaha ka monopoli haole.
Wahi a Zhao Guangpu, ke alakaʻi o ka papahana noiʻi a me ka hope alakaʻi o ka Steel Research Gona Science and Technology Committee, ʻo nā turbines kinoea kaumaha no nā kikowaena mana nui he mau pōmaikaʻi maikaʻi loa e like me ka mana kiʻekiʻe, kiʻekiʻe thermal efficiency, liʻiliʻi leo a me ke kaumaha. a me ka haumia haʻahaʻa.Ua lilo kona ʻenehana hana i pae ʻenehana aupuni., ʻO kekahi o nā hōʻailona koʻikoʻi o ka ikaika aupuni ākea.ʻO kāna mau mea wela wela hoʻokahi diski a me ʻelua (nā disc turbine a me nā alakaʻi, nā lau hana), e hana nei ma ke ʻano he "naʻau" o ke kanaka.ʻO lākou ka ʻenehana koʻikoʻi no ka hana ʻana i ka turbine kinoea a me ka bottleneck e kaupalena ana i ka localization o nā turbine kinoea kaumaha.ʻO nā disks turbine turbine koʻikoʻi e koi aku ma mua o 100,000 mau hola o ka lawelawe lōʻihi kiʻekiʻe a me ke koʻikoʻi, a koi aku i ka maikaʻi metallurgical kiʻekiʻe loa o nā mea, e like me ka homogeneous, pure, fine-grained, stable material structure and performance;nui ka nui, a me kona anawaena a me ka projection wahi pakahi Ua hiki oi aku ia ma mua o 2.2 mika a me 4.2 huinahalike mika, i mea 4 manawa ka anawaena o ka aero engine turbine diski, 10 manawa o ka projected wahi, a me 60 manawa o ke kaumaha, a pela aku. .ʻO ka ʻenehana hana koʻikoʻi o nā diski turbine super-sized superalloy i hoʻopaʻa ʻia ma waho a ua hoʻomalu 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 hope ua lawe ʻo ia i ka ʻenehana hoʻomākaukau ʻoi loa o ka honua "ʻekolu hoʻoheheʻe ʻana + hoʻopau hou + ʻelua huhū + hoʻokahi-ahi holoʻokoʻa make forging" ʻenehana hoʻomākaukau e hoʻokō. ka International Standards, e haki ana i ka bottleneck ʻenehana o ka superalloy turbine disk hoʻomākaukau nui i ʻike ʻia i ka wā o ka hoʻomohala ʻana, e like me ka ʻenehana hoʻoheheʻe haʻahaʻa haʻahaʻa ʻekolu no nā ingots kila nui me nā ingots ʻoi aku ka nui ma mua o 18 tons, a me ka hoʻopiʻi pinepine ʻana a me ka palaoa maikaʻi. ʻenehana mohala no nā kaola nui me ke anawaena o 1000 mm, me ke anawaena o 2200 Integral die forging a me ka hoʻokumu ʻana i ka wela haʻahaʻa a me ka ʻenehana hoʻonohonoho hoʻonohonoho no nā ʻāpana pā nui i ʻoi aku ka nui ma mua o nā millimeters.Ua hoʻokō ka hui papahana i ka noiʻi kūʻokoʻa a me ka hoʻomohala ʻana a me nā hana hou no nā hemahema metallurgical e like me ke kiʻekiʻe Nb maʻiʻo o ka mea hoʻohui i loko o ka superalloy GH4706, kahi mea maʻalahi i nā kiko ʻeleʻele a me ka hoʻokaʻawale wahi keʻokeʻo.ʻO nā ʻāpana wela wela nui o koʻu ʻāina ʻo ka "paʻa ʻāʻī", i wehe i kahi ala kaʻina no ka hoʻomākaukau ʻana i nā disks turbine superalloy deformed nui me nā ʻano Kina me nā kuleana waiwai naʻauao kūʻokoʻa.
Ma hope o ka anatomy, ua hōʻea ka hana o ka turbine disc i nā koi ʻenehana o nā ʻāpana ʻē aʻe like, a ua loaʻa kahi hopena milestone.ʻO kēia kekahi mea koʻikoʻi koʻikoʻi a koʻu ʻāina i hana ai ma ke kahua o nā superalloy deformed, ka mea i alakaʻi i ka ʻenehana hoʻomākaukau o nā diski turbine super-nui a hiki i ka pae alakaʻi honua.Ma ka lā 8 o Kekemapa, ua mālama ʻia ka hālāwai loiloi node milestone no GH4706 alloy full-size roulette forgings ma Beijing.Ua hāʻawi ka poʻe loea i kahi loiloi kiʻekiʻe, ʻo ia hoʻi, ua hana ʻia kahi hana paʻa i ka hoʻohana maoli ʻana o ka turbine disk.
