ʻO ke kaʻina hana grafitization o ka hao hao a me nā mea e hoʻopili i ka graphitization o ka hao hao

 1. Ke kaʻina hana kiʻi o ka hao hao

    ʻO ke kaʻina hana o ka graphite i ka hao hao i kapa ʻia ka hana graphitization. ʻO ke kaʻina hana o ka hana o ka hao hao ke kaʻina hana o ka graphite i ka hao hao. No laila, he mea nui e hoʻomaopopo i nā kūlana a me nā mea e hoʻohuli ai i ka hana graphitization e haku i ka hanana a me nā waiwai o nā mea hao hao.

    Wahi a ke kiʻi mokuʻāina pālua o ke aniani ʻo Fe-C, hiki ke hoʻokaʻawale ʻia ka hana graphitization o ka hao hao i ʻekolu mau pae:

    ʻO ka pae mua ke kaʻina wai hypoeutectic crystallization pae. Me ka crystallization pololei o ka graphite mua mai ka pae wai o nā mea hypereutectic a me ka pae wai o nā mea eutectic e crystallize austenite a me ka graphite, ka graphite i hana ʻia e ka decomposing primite siteite a me eitectic citeite i ka wā o ka annealing wela kiʻekiʻe.

    ʻO ka pae waena ka pae ma waena o ka hoʻololi eutectic a me ka hypoeutectoid hoʻololi. Me ka ua pololei o ka graphite lua mai austenite a me ka graphite i hana ʻia e ka decomposition o ka lua semiite i kēia pae wela.

    ʻO ke kolu o ka pae, ʻo ia ka manawa hoʻololi o ka hōʻemi loa. Me ka graphite eutectoid i hana ʻia i ka wā o ka hoʻololi like ʻana a me ka graphite i hana ʻia e ka decomposition o ka eutectoid citeite i ka wā hoʻohui.

2. Nā mea e hoʻopili ana i ka graphitization o ka hao hao

    ʻO ke ʻano o ka hao hao e pili ana i ka pae o ka graphitization. I mea e loaʻa ai ke ʻano i koi ʻia, ʻo ke kī kaohi i ke kēkelē o ka graphitization. Ua hōʻoia ka hoʻomaʻamaʻa i nā kumu he nui e like me ka hoʻohui kemika o ka hao hao, ke anuanu o nā aniani hao hao, ka hoʻomehana ʻana a me ke kū ʻana o ka hao hoʻoheheʻe, a me nā mea ʻē aʻe, pili i ka graphitization a me ka microstructure o ka hao hao.

1. Ka hopena o ka hoʻohui kemika

    Ma waena o nā mea maʻamau C, Si, Mn, P, a me S ma ka hao hao, ʻo C a me Si nā mea e hāpai nui i ka hoʻolālā kiʻi ʻana, a ʻo S kahi mea e keʻakeʻa nui i ka kiʻi ʻana. I ka ʻoiaʻiʻo, ka pīhoihoi o ka mana o kēlā me kēia me kēia ma ka hiki i ka graphitization o ka hao hao ke paʻakikī loa. Pili ka hopena i ka ʻike o kēlā me kēia pono ponoʻī a inā e launa pū me nā mea ʻē aʻe, e like me Ti, Zr, B, Ce, Mg, a pēlā aku. Ce <0.01%, T <0.08%), hōʻike lākou i ka hopena o ka hāpai ʻana i ka graphitization.

2. Ka hopena o ke ana hōʻoluʻolu

    'Lelo maʻamau, ʻoi aku ka lohi o ka helu anuanu o ka hoʻoheheʻe ʻana, ʻoi aku ka maikaʻi o ka crystallization a me ka hoʻololi ʻana e like me ke kiʻi mokuʻāina o ka ʻōnaehana paʻa Fe-G, a me ka piha graphitization; ma ka ʻaoʻao ʻē aʻe, maikaʻi no ka crystallization a me ka hoʻololi ʻana e like me ke kiʻikuhi mokuʻāina o Fe-Fe3C metastable ʻōnaehana. Loaʻa i ka hao hao keʻokeʻo. ʻOi loa i ka graphitization ma ka pae eutectoid, ʻoiai haʻahaʻa ka mahana, piʻi ka anuanu anuanu, a paʻakikī ka diffusion o nā ʻoma, he paʻakikī ia e holomua piha i ka graphitization ma ka pae eutectoid.

    ʻO ke anuanu o ka hao hao he mea nui, e pili ana i ka mahana ninini, ka conductivity mehana o nā mea hoʻoheheʻe a me ka mānoanoa o ka pā. A maʻamau ka hopena like o kēia mau kumu i nā pae ʻelua.

    Hiki i ka hoʻonui ʻana i ka mahana ninini ke hoʻolohi i ka helu hoʻoluʻu o ka ninini ʻana, kahi e hāpai ai i ka pae mua o ka hoʻolālā ʻana a me ka pae ʻelua o ka hoʻolālā ʻana. No laila, ʻo ka hoʻonui ʻana i ka mahana ninini e hiki ai iā ia ke pulverize i ka graphite i kekahi nui, a hiki ke hoʻonui i ka hoʻololi ʻana o ka eutectoid.

3. Ka hopena o ka wela a me ke kiʻekiʻe o ke ana wela o ka hao hao

    Ma loko o kahi pae mahana, e hoʻonui ana i ka mahana wela o ka hao hoʻoheheʻe a hoʻonui i ka manawa kū kiʻekiʻe o ka mahana wela e hopena i ka hoʻomaʻemaʻe o ka hoʻolālā grafite i ka hao hao a hoʻonui i ka ikaika o ka hao hao. Inā hoʻomāhuahua hou ʻia ka superheat, e emi ana ka hiki o ka hao hao, a e hōʻino ʻia ka morphology graphite, a e ʻike ʻia ka simite free, kahi e hoʻēmi ai i ka ikaika, no laila aia kahi wela wela. ʻO ka wela koʻikoʻi ma muli o ka hoʻohui kemika o ka hao hoʻoheheʻe a me ka helu hōʻoluʻolu o ka hoʻoheheʻe ʻana. Manaʻo nui ʻia ʻo ka mahana koʻikoʻi o ka hao hao hina ma kahi o 1500-1550 ℃, no laila ke lana mau nei ka manaʻo ʻoi aku ka kiʻekiʻe o ke ana wela o ka hao.

E ʻoluʻolu e mālama i ke kumu a me ka helu wahi o kēia ʻatikala no ka paʻi hou ʻana: ʻO ke kaʻina hana grafitization o ka hao hao a me nā mea e hoʻopili i ka graphitization o ka hao hao

Minghe ʻOihana Casting Die hoʻolaʻa ʻia no ka hana ʻana a hāʻawi i ka maikaʻi a me ka hana kiʻekiʻena hana ʻana i nā ʻāpana (metala make e hoʻolei ana i nā ʻāpana i ka nui Ke kīloi ʻana ʻo Thin-Wall Die,Ka Hapa Hapa Kaʻa Hapa,ʻO ka hoʻoheheʻe ʻana o ke keʻena anu), Ke Kūʻai Wāwae (Die Casting Service,Cnc mīkini,Hana Mould, ʻIlikai Ma luna). Hoʻokipa ʻia nā mea make Alumini maʻamau, magnesium a Zamak / zinc make casting a me nā koi hoʻoiho ʻē aʻe e hoʻokaʻaʻike iā mākou.

Ma lalo o ka hoʻomalu o ISO9001 a me TS 16949, lawelawe ʻia nā kaʻina hana āpau ma o nā haneli he nui o nā mīkini ninini make, nā mīkini 5-axis, a me nā pono hana ʻē aʻe, mai nā blasters a i nā mīkini holoi ʻo Ultra Sonic. kime o nā ʻenekini ʻike, nā mea hana a me nā mea nānā e hana i ka hoʻolālā a ka mea kūʻai aku.

Mea hana aelike o ka hoʻoheheʻe make ʻana. Hiki i nā mākau ke komo i nā ʻāpana alumini anu e hoʻolei ana i nā ʻāpana mai 0.15 lbs. i 6 lbs., hoʻonohonoho wikiwiki i hoʻonohonoho ʻia, a me ka mīkini ʻana. ʻO nā lawelawe i hoʻohui ʻia me ka waiwai nā polishing, vibrating, deburring, shot blasting, pena, plating, coating, Assembly, a me nā meahana. Hana pū nā meahana me nā alloys e like me 360, 380, 383, a me 413.

Kōkua hoʻolālā hoʻolei Zinc make casting / ʻenehana ʻenehana ʻelua. ʻO ka mea hana hana hana maʻamau no ka hoʻoheheʻe ʻana i zinc zinc. ʻO ka hoʻoheheʻe liʻiliʻi ʻana, nā kiʻekiʻena make kiʻekiʻe, nā hoʻoheheʻe hoʻoheheʻe multi-slide, nā hana hoʻoheheʻe maʻamau, kahi make a me nā hana make make kūʻokoʻa a hiki ke hana ʻia nā kīkō i hoʻopaʻa ʻia. Hiki ke hana i ka hoʻoheheʻe ʻana i ka loa a me ka laulā a i ka 24 in. I +/- 0.0005 in. Ke ahonui.  

ISO 9001: 2015 mea hana i hōʻoia ʻia o ka magnesium make, hiki i nā mea hiki ke hoʻokomo i ka magnesium make kiʻekiʻe a hiki i 200 ton keena wela & 3000 keena anuanu, hoʻolālā mea hana, hoʻonani ʻana, hoʻoheheʻe ʻana, mīkini, pauma a me ka pena wai, piha QA me nā hiki CMM. , ʻaha kanaka, ʻōpala & hoʻouna.

ITAF16949 i hōʻoia ʻia. Pākuʻi ʻia kahi lawelawe hoʻolei hou hoʻoili waiwai,wailū,Kāpili Gravity, ʻO ka mōkī holo Foam,Ka Kūleʻa Kalima,Huina Kāleka,Holo paʻa punahelu, .Kāpono pū me EDI, kōkua ʻenehana, hoʻohālikelike paʻa a me ka hana lua.

ʻO nā ʻĀpana Casting Nā ʻ Caselelo Nānā Nānā no: Nā Kaʻa, nā Paikikala, nā mokulele, nā mea kani, nā pono wai, nā mea uila, nā mīkini uila, nā mīkini, nā pono uila, nā mea paʻa, nā uaki, nā mīkini, nā ʻenekini, nā lako pono, nā mea kāhiko, nā Jigs, Telecom, kukui Nā Robots, nā kiʻi kālai, nā pono kani, nā pono haʻuki, nā pono hana, nā mea pāʻani a me nā mea hou aʻe. 

He aha ka mea e hiki ai iā mākou ke kōkua iā ʻoe e hana aʻe?
