Hiki i nā hoʻolei valve ke hana i nā hemahema

1. Ka stomata

He lua liʻiliʻi kēia i hana ʻia e ke kinoea i pakele ʻole ke kaʻina hana paʻa metala i loko o ka metala. He laumania kona paia i loko a loaʻa ke kinoea, he kiʻekiʻe ka reflectivity i ka hawewe kani ultrasonic, akā, no ka mea, he spherical a ellipsoid paha, he wahi hemahema ia, e pili ana i kona amplitude noʻonoʻo. Hoʻopili ʻia ka lua ea i loko o ka ingot i kahi hemahema ma hope o ka hana ʻana a i ʻole ka ʻōwili ʻana, kahi mea e pono ai ke ʻike ʻia e ka ultrasonic detection.

2. Paʻi paʻi

ʻO ka slag i loko o ke kaʻina hoʻoheheʻe a i ʻole ka refractory ma ke kino o ka umu ahi e peels i loko o ka metala wai, a komo i loko o ka hoʻolei ʻana a i ʻole ke kila ingot i ka wā e ninini ai, e hoʻokumu ana i ka slag clamp defect. ʻAʻole noho hoʻokahi ka Slag, pinepine i loko o kahi ʻano paʻa a i ʻole i hoʻopuehu ʻia i nā hohonu like ʻole, ua like ia me nā kīnā leo akā loaʻa pinepine kahi laina.

3. Hoolei mawae

ʻO ka māwae i ka hoʻolei ʻia ʻana ma muli o ke koʻikoʻi shrinkage o ka hoʻoheheʻe ʻana i ka metala ma mua o ka ikaika hope loa o ka mea, pili ia i ke ʻano o ka hoʻolālā hoʻoheheʻe ʻana a me ke kaʻina hoʻolei ʻana, a pili pū kekahi i ka naʻau o kekahi mau haumia i loko. nā mea metala (e like me ke kiʻekiʻe o ka sulfur maʻiʻo, ke anuanu brittleness, kiʻekiʻe phosphorus maʻiʻo, etc.). I loko o ka milo, e loaʻa nō hoʻi nā māwae i loko o ka pahu aniani, a i ka hana ʻana i ka billet ma hope, e mau nō ia i ka forging e like me ka māwae kūloko o ka forging.

4. Huli i ka ʻili

ʻO kēia ka mea hana kila mai ka ladle a hiki i ka ingot hoʻolei ʻana i ka ingot, no ka ninini ʻana i ka interruption, hoʻomaha, ninini ʻia i loko o ka wai metala ili i ka lewa wikiwiki hoʻomaha ʻano oxide film, ka ninini hou ʻana i loko o ka metala wai e haki i loko o ke kino ingot a hana i kahi hierarchical. (area) defects, ia ma ka hope ingot billet forging ʻaʻole forging.

5. Anisotropy

Ke hoʻomaloʻo a hoʻopaʻa ʻia ka hoʻolei ʻana a i ʻole ka ingot, ʻokoʻa ka wikiwiki hoʻoluʻu mai ka ʻili a i ke kikowaena, no laila e hoʻokumu ʻia ka ʻiʻo crystallization ʻē aʻe, e hōʻike ana i ka anisotropy o nā waiwai mechanical, a alakaʻi pū i ka anisotropy o nā waiwai acoustic, ʻo ia hoʻi. , he okoa ka leo velocity a me ka leo attenuation mai ke kikowaena a i ka ili. Hiki ke loaʻa ka hopena o kēia anisotropy i ka nui a me ke kūlana o nā hemahema i loiloi ʻia i ka wā o ka ʻike ultrasonic.

Ma waho aʻe o kēia, ʻo Tianjin Tanggu Water Seal Valve Co., Ltd. he ʻenehana hoʻomohala elastic seat valve e kākoʻo ana i nā ʻoihana, nā huahana.noho lauwili wafer butterfly valve, lug butterfly valve, double flange concentric butterfly valve, double flangekiwi lele lele eccentric, pāpaʻi kaulike, pāpaʻi ʻālua pāpaʻi ʻālua,Y-Srainera pela aku. Ma Tianjin Tanggu Water Seal Valve Co., Ltd., haʻaheo mākou iā mākou iho i ka hāʻawi ʻana i nā huahana papa mua e kū ana i nā kūlana ʻoihana kiʻekiʻe. Me kā mākou ākea ākea o nā valves a me nā pono, hiki iā ʻoe ke hilinaʻi iā mākou e hāʻawi i ka hopena kūpono no kāu ʻōnaehana wai. E kelepona mai iā mākou i kēia lā e aʻo hou e pili ana i kā mākou huahana a pehea e hiki ai iā mākou ke kōkua iā ʻoe.
