He mea maʻalahi nā hoʻoheheʻe valve e hana i nā hemahema

1. ʻO ka stomata

He lua liʻiliʻi kēia i hoʻokumu ʻia e ke kinoea i ʻole e puka aku ke kaʻina hana paʻa metala i loko o ka metala. He laumania kona paia o loko a loaʻa iā ia ke kinoea, nona ka reflectivity kiʻekiʻe i ka nalu ultrasonic, akā no ka mea he poepoe a ellipsoid paha, he kīnā kiko ia, ka mea e hoʻopilikia ai i kona amplitude reflection. Hoʻopalahalaha ʻia ka lua ea i loko o ka ingot i loko o kahi kīnā wahi ma hope o ka forging a i ʻole ka ʻōwili ʻana, he mea maikaʻi ke loaʻa ma o ka ʻike ultrasonic.

2. ʻOkiʻoki i ka ʻōpala

ʻO ka ʻōpala i ke kaʻina hana hoʻoheheʻe a i ʻole ka refractory ma ke kino umu e ʻili i loko o ka metala wai, a komo i loko o ka ingot hoʻolei a i ʻole ke kila i ka wā e ninini ana, e hana ana i ka hemahema slag clamp. ʻAʻole noho wale ka slag, pinepine i kahi kūlana mānoanoa a i ʻole i hoʻopuehu ʻia ma nā hohonu like ʻole, ua like ia me nā hemahema volume akā pinepine he linearity kekahi.

3. Ke hoʻolei ʻana i nā māwae

ʻO ke kumu nui o ka māwae i loko o ka hoʻolei ʻana, ʻo ia ke koʻikoʻi o ka hoʻomāalili ʻana o ka metala ma mua o ka ikaika hope loa o ka mea, pili ia i ke ʻano o ka hoʻolālā hoʻolei a me ke kaʻina hana hoʻolei ʻana, a pili pū kekahi i ka ʻike o ka haki ʻana o kekahi mau haumia i loko o nā mea metala (e like me ka nui o ka sulfur, ka brittleness anu, ka nui o ka phosphorus, a pēlā aku). I loko o ke koʻokoʻo, e loaʻa nō hoʻi nā māwae i loko o ke aniani koʻokoʻo, a i ka hana ʻana o nā billet ma hope, e noho mau ia i loko o ka hana ʻana ma ke ʻano he māwae kūloko o ka hana ʻana.

4. E hoʻohuli i ka ʻili

ʻO kēia ka hana kila mai ka ladle a i ka ingot cast ingot. Ma muli o ka ninini ʻana i ka hoʻopau ʻana, hoʻomaha iki, ninini ʻia i loko o ka ʻili metala wai i ka lewa e hana i kahi ʻili oxide e hoʻomaʻalili wikiwiki ai. ʻO ka ninini hou ʻana i loko o ka metala wai e haki i loko o ke kino ingot a hana i kahi hierarchical (wahi) kīnā, ʻaʻole ia e hana ʻia ma ka billet forging ingot ma hope.

5. ʻAnisotropy

Ke hoʻomaʻalili ʻia a paʻa ka hoʻolei ʻana a i ʻole ka ingot, ʻokoʻa ka wikiwiki o ka hoʻomaʻalili ʻana mai ka ʻili a i ke kikowaena, no laila e hana ʻia nā ʻiʻo crystallization like ʻole, e hōʻike ana i ka anisotropy o nā waiwai mechanical, a alakaʻi pū kekahi i ka anisotropy o nā waiwai acoustic, ʻo ia hoʻi, he ʻokoʻa ka wikiwiki o ke kani a me ka hoʻēmi ʻana o ke kani mai ke kikowaena a i ka ʻili. Hiki i ke alo o kēia anisotropy ke loaʻa ka hopena maikaʻi ʻole i ka nui a me ke kūlana o nā hemahema i loiloi ʻia i ka wā o ka ʻike ʻana o ka ultrasonic.

Eia kekahi, ʻo Tianjin Tanggu Water Seal Valve Co., Ltd. he ʻenehana holomua i ka noho elastic e kākoʻo ana i nā ʻoihana, ʻo nā huahanakiwikā pulelehua wafer noho elastic, kiwikā pulelehua lug, kiwikā pulelehua concentric flange pālua, flange pāluakiwikā pulelehua ʻano ʻē, kiwikā kaulike, kiwikā nānā papa pālua wafer,Kānana Ya pēlā aku. Ma Tianjin Tanggu Water Seal Valve Co., Ltd., haʻaheo mākou i ka hāʻawi ʻana i nā huahana papa mua e hoʻokō ana i nā kūlana ʻoihana kiʻekiʻe loa. Me kā mākou ākea o nā valves a me nā mea hoʻopili, hiki iā ʻoe ke hilinaʻi iā mākou e hāʻawi i ka hopena kūpono no kāu ʻōnaehana wai. E kāhea 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.
