ʻO ka nui nui o ka C11000 Pure Copper Square Tube - Hoʻokele wela kiʻekiʻe

ʻO ka Tube ʻUlaʻula Keleawe - Kaʻina Hana a me ka Hōʻoiaʻiʻo Kūlana

Hana ʻia kā mākou mau paipu keleawe ʻulaʻula mai ke keleawe ʻole oxygen kiʻekiʻe (Cu ≥ 99.95%) a i ʻole ka cathode keleawe T2 me ka hoʻohana ʻana i kahi kaʻina hana piha: hoʻomau i ka hoʻolei ʻana/horizontal continuous casting → multi-pass cold extrusion → intermediate annealing → drawing to the final size → finishing and straightening → NDT inspection → cleaning and protective packaging. Hōʻoia kēia i ka microstructure paʻa, ka nui o ka palaoa like, a me ka conductivity uila a me ka thermal maikaʻi loa.

Nā hiʻohiʻona hana koʻikoʻi

● ʻO ka lakio extrusion kiʻekiʻe (≥ 30:1) i ke kahua extrusion e wāwahi pono i nā hua coarse as-cast a hoʻokō i ka recrystallization piha;
● ʻO ka kaha kiʻi multi-pass i hui pū ʻia me ʻelua mau pōʻaiapuni annealing ʻālohilohi vacuum e hoʻopau i ke kaumaha kūloko a pale i ka oxidation intergranular, e mālama ana i ka maʻemaʻe kiʻekiʻe ma ka ʻili a ma loko o ka mea;
● Nā ʻae ʻana o ke ana i kāohi ʻia i loko o ±0.05 mm, ka loli o ka mānoanoa o ka paia ≤ 3%, ka pololei ≤ 0.5 mm/m, a me ke kūlike diagonal kiʻekiʻe e ʻoi aku ana ma mua o nā koi kūlana aupuni papa mua;
● Hoʻopau ka hoʻāʻo ʻana o ke au eddy 100% i hoʻohui ʻia e ka nānā ʻana o ka ultrasonic i nā māwae o ka ʻili a me lalo, nā mea i hoʻokomo ʻia, ka ʻili ʻalani, a me nā kīnā ʻē aʻe.

ʻŌnaehana hoʻomalu maikaʻi

● Nānā ʻia nā mea maka e hiki mai ana i kēlā me kēia ʻāpana me ka spectrometer heluhelu pololei no ka haku mele kemika a me ka nui o ka hydrogen/oxygen;
● Ua hoʻokō ʻia ka mana hana SPC ma kēlā me kēia pae hana; ua ana ʻia a hoʻopaʻa ʻia nā ana koʻikoʻi 100% ma ka pūnaewele;
● Ma mua o ka hoʻouna ʻana, e hoʻāʻo ʻia ka conductivity uila o kēlā me kēia paipu (≥ 101% IACS), ka ʻike ʻana i nā hemahema o ke au eddy, ka hoʻāʻo paʻa o ke kaomi (15 bar × 30 min, ʻaʻohe leakage), ka nānā piha ʻana i ka nui, a me ka hōʻoia ʻana i ka maikaʻi o ka ʻili;
● Loaʻa nā hōʻike nānā ʻaoʻao ʻekolu (SGS, BV, AHK, a me nā mea ʻē aʻe) a me nā moʻolelo hana piha e hiki ai ke hahai ʻia ma ke noi.

He kūpono loa no nā kaʻa pahi ʻāpana nui, nā paipu hoʻololi wela, nā papa hoʻomaʻalili wai i nā ʻōnaehana ikehu hou, nā mea hoʻohui alakaʻi ʻoihana, a me nā noi ʻē aʻe kahi e koʻikoʻi ai ka pololei o ka dimensional, ka conductivity uila, ka paʻa kinoea, a me ka hilinaʻi lōʻihi.

He loea mākou i ka hoʻolako ʻana i nā ʻōmole keleawe ʻulaʻula kūlike, hiki ke hahai ʻia, a hana kiʻekiʻe i nā mea pāʻani ʻoihana alakaʻi ma ka honua holoʻokoʻa.
