E like me ke ʻano neʻe o kāu punahelekalai make, wiliwili palahalahahiki ke hoʻokaʻawale ʻia i loko o ka swing rolling, swing rotaryke kalaiwa ana, ʻōwilike kalaiwa ana, wili kea, kawili apo, kawili kea, etc.ʻO ka hana pololeihiki ke hoʻohana ʻia i ka swing rolling, swing rotary forging and ring rolling. Hiki ke hoʻohana ʻia ka ʻōwili ʻana a me ka ʻōwili keʻa e like me ka hoʻomaʻamaʻa mua ʻana i nā mea lohi e hoʻomaikaʻi ai i ka hoʻohana ʻana i nā mea. E like me ka forging manuahi, hoʻokumu ʻia ʻo rotary forging a loaʻa ka pōmaikaʻi o ka hana ʻana inā ʻo kake kalaiwa anaʻoi aku ka liʻiliʻi o ka ikaika ma mua o ka nui forging. Hiki ke hoʻopau ʻia nā forging paʻakikī i hoʻokahi a ʻoi aku paha kaʻina hana. No ka mea, ʻaʻohe ʻaoʻao ʻoʻoleʻa, ua hoʻemi ʻia ka wahi i hoʻopaʻa ʻia a hoʻemi ʻia ka ukana i koi ʻia.

ʻO kēiake kalaiwa anaʻO ke ala e hoʻonui ai i ka mea mai kahi kokoke i ka wā e mīkini ai i ka flange welded flat. No ka mea, ʻokoʻa ka mamao ma waena o ka ʻili make a me ka ʻili manuahi, paʻakikī ke hōʻoiaʻiʻo ʻana, no laila ma ka hoʻomalu ʻana i ke kuhikuhi o ka forging die a me ka rotary forging process, hiki ke hana ʻia ka huahana me ke ʻano paʻakikī a me ka pololei kiʻekiʻe. Maopopo iaʻu. Hiki iaʻu ke hana. Loaʻa me ka mana forging haʻahaʻa. ʻO nā lau turbine a me nā ʻano ʻē aʻe a me ka nui nuike kalaiwa anahana ʻana.

ʻO kake kalaiwa anaHiki ke hoʻokaʻawale ʻia ka flange welded flat i ka forging manuahi, huhū, extrusion, make forging, pani pani ʻia.ke kalaiwa anaa me ka hoʻopaʻa ʻana i ka hana ʻino. ʻO ka mea maʻamau, kapa ʻia ka forging i ka pae wela me ka recrystallization ʻo ka hoʻomaʻamaʻa wela, a ʻo ka forging me ka ʻole o ka hoʻomehana ʻana i ka lumi wela ua kapa ʻia ʻo ke anuanu. Ke hana ʻia nā flanges welded palahalaha i nā mahana haʻahaʻa, ʻaʻole hiki ke loli ka nui o nā forgings. I ka manawahoʻopunipunima lalo o 700 ℃, aneane ʻaʻohe ʻili oxide a ʻaʻohe decarburization o ka honua.

Flange wiliwili palahalahake kumu hoʻopaʻa paʻa: ua kaomi ʻia nā ʻaoʻao hoʻopaʻa ʻelua o ka bolt ma ka flange gasket e hana i kahi sila, a hiki ke alakaʻi i ka hōʻino sila. No ka mālama ʻana i ka sila, pono e mālama ʻia ka ikaika o ka bolt, no laila pono e hoʻohui ʻia nā bolts hou. Pono ke kī nui me ka nut nui. 'O ia ho'i, e pono ana 'oe i ka wili anawaena nui a'e e hana i nā kūlana no ka ho'opa'a 'ana i ka nut.

Hoʻomalu nowiliwili palahalaha

1, no ka hana ana i flat welding flange steelhana ʻia ka pā a hoʻohana ʻia e ka ultrasonic inspection me ka ʻole o ka lamination defects, i mea e ʻike ai i ka maikaʻi maikaʻi a me nā pilikia hana, a e like me nā koi kikoʻī o ka hana ʻana a me ka nānā ʻana, ʻaʻohe pilikia o ke kila kila.

2, pono e ʻoki ʻia ke kila i loko o nā ʻāpana ma ka ʻaoʻao o ka ʻōwili, a laila e kulou a hoʻopaʻa ʻia i ke apo i loko o ke apo, e hana ana i kahi ʻāpana pōʻai ma ke kila. ʻO ke kinikini. I ka hana ʻana i nā flanges welded maʻamau, ʻaʻole pono e mīkini ʻia nā papa kila ma lunaʻāʻī flanges, akā hana ʻia a hana ʻia me ka hoʻohana ʻana i nā ʻenehana kikoʻī.
