Ke kaomi ʻana
Hoʻokomo ʻia ia i loko o kahi paʻi hydraulic a i ʻole mechanical kahi i waiho ʻia i loko o kahi mea kila a i ʻole carbide make i ka manawa i hui ʻia ai ka huila kūpono o nā pauka. Hiki iā JIEHUANG ke kaomi i nā ʻāpana me nā pae ʻokoʻa ʻehā o nā kikoʻī maikaʻi. Ma muli o ka nui a me nā koi koi, hoʻohana kēia ʻano i ke kaomi 15-600MPa e hana i nā ʻāpana "'ōmaʻomaʻo" i loaʻa nā hiʻohiʻona geometric pono o ka hoʻolālā hope. Eia naʻe, ʻaʻole ʻike ʻia nā ana hope loa o ka ʻāpana a i ʻole kona mau hiʻohiʻona mechanical i kēia manawa. ʻO ka hana wela ma hope, a i ʻole "sintering," e hoʻopau i kēlā mau hiʻohiʻona.
ʻO ka hoʻopaʻa ʻana i ka metala (ka hana hoʻopaʻa ʻana i ka pauka metallurgy)
Hāʻawi ʻia nā ʻāpana ʻōmaʻomaʻo i loko o kahi umu sintering a hiki i nā ikaika hope e pono ai, density, a me ke kūpaʻa dimensional. I ke kaʻina hana o ka sintering, ua wela ka mahana ma lalo o ka helu heheʻe o ka ʻāpana pauda nui o ka ʻāpana i loko o kahi kaiapuni i pale ʻia e hoʻopili i ka molecularly i nā ʻāpana pauda metala i hana i ka ʻāpana.
Ke ulu nei ka nui a me ka ikaika o nā kiko hoʻopili ma waena o nā ʻāpana i hoʻopaʻa ʻia e hoʻomaikaʻi i nā ʻano ʻenehana o ka mea. I mea e hoʻokō ai i nā ʻāpana ʻāpana hope loa, hiki i ka sintering ke emi, hoʻonui, hoʻomaikaʻi i ka conductivity, a/a i ʻole e hoʻoikaika i ka ʻāpana ma muli o ke kaʻina hana. I loko o kahi kapuahi sintering, hoʻokomo ʻia nā ʻāpana i kahi conveyor mau a lawe mālie ʻia i loko o nā keʻena o ka umu e hoʻokō i ʻekolu mau hana nui.
No ka hoʻopau ʻana i nā lubricants i makemake ʻole ʻia i hoʻohui ʻia i ka pauka i ka wā o ka hoʻopaʻa ʻana, e hoʻomehana mua ʻia nā ʻāpana. ʻO nā ʻāpana aʻe e hele i ka wahi wela kiʻekiʻe o ka umu, kahi i hoʻoholo ʻia ai nā ʻano hope o nā ʻāpana i nā mahana i hoʻomalu pono ʻia mai 1450 ° a 2400 °. Ma ka hoʻohālikelike pono ʻana i ka lewa i loko o kēia keʻena umu, ua hoʻohui ʻia kekahi mau kinoea e hoʻemi i nā oxides i loaʻa a hoʻopau i ka oxidation hou o nā ʻāpana i kēia wā wela kiʻekiʻe. No ka hoʻopiha ʻana i nā ʻāpana a hoʻomākaukau paha no nā kaʻina hana hou aʻe, hele lākou i loko o kahi keʻena hoʻomaha. Ma muli o nā mea i hoʻohana ʻia a me ka nui o nā ʻāpana, hiki i ke kaʻina holoʻokoʻa ke lawe i 45 mau minuke a 1.5 mau hola.
Mahope o ka hana ana
Ma keʻano laulā, kanā huahana sinteringhiki ke hoʻohana pololei. Eia nō naʻe, no kekahi mau huahana metala sinter e koi ana i ka pololei kiʻekiʻe a me ka paʻakikī kiʻekiʻe a me ke kūpaʻa ʻana, pono ka mālama ʻana ma hope o ka sintering. Ma hope o ka hoʻoponopono ʻana e pili ana i ke kaomi pololei, ka ʻōwili, extrusion, quenching, surface quenching, oil immersion, and infiltration.
Kaʻina hana lapaʻau o ka pauda metallurgy
Hiki iā ʻoe ke hālāwai me nā huahana metallurgy pauka,nā mea hao hao paudai maʻalahi i ka ʻōpala, maʻalahi i ka ʻōpala, a me nā mea ʻē aʻe, i mea e hoʻomaikaʻi ai i ke kūpaʻa ʻaʻahu, ka pale ʻana i ka ʻōpala, ka pale ʻana i ka corrosion a me ka ikaika luhi o nā ʻāpana metallurgy pauka. E hoʻokō ʻo Jiehuang i ka mālama ʻana ma luna o nā ʻāpana metallurgy pauka, ʻo ia ka mea e hana ai i kona ʻili i ʻoi aku ka hana, a e hoʻomāhuahua i ka ʻili. No laila he aha nā kaʻina hana lapaʻau lepo metallurgy?
ʻElima mau kaʻina hana lapaʻau maʻamau i ka pauka metallurgy:
1.ka uhi:ʻO ka uhi ʻana i kahi papa o nā mea ʻē aʻe ma luna o ka ʻili o nā ʻāpana metallurgy pauka i hana ʻia me ka ʻole o ka hopena kemika;
2.Mechanical deformation ala:ʻO ka ʻili o nā ʻāpana metallurgy pauka e hana ʻia me ka mechanical deformed, ka mea nui e hoʻoulu i ke koʻikoʻi koena compressive a e hoʻonui i ka ʻili.
3.Lapaʻau wela kemika:ʻO nā mea ʻē aʻe e like me C a me N e laha i ka ʻili o nā ʻāpana i mālama ʻia;
4.Lapaʻau wela ʻili:hiki ke hoʻololi i ka pae ma o ka hoʻololi cyclic o ka mahana, e hoʻololi i ka microstructure o ka ʻili o ka ʻāpana i mālama ʻia;
5.Lapaʻau kemika ʻili:ka hopena kemika ma waena o ka ʻili o ka ʻāpana metallurgy pauda e mālama ʻia a me ka reactant waho;
O NA MAPA METAL KIEKIE KO KAKOU ANOAI NO NA HANA HANA. KUPONO KO KAKOU HANA NO NA MEA A PAU, ME NA HANA HOOLAHA POWER DUTY HEAVY DUTY POWER TRANSMISSIONS A ME NA LAKO LAPAAU MELE.
