Hoʻolei ʻana i ka hao hoʻoheheʻe

OEM maʻamau ductile hoolei hao mekaʻina hoʻolei kālāmai ka hui hoolei Kina. Hiki iā mākou ke hāʻawi i nā lawelawe oʻO ka mīkini CNC, hui a me ka lapaʻau ʻana.

ʻO nā hao hao he mau ferrous alloys i loaʻa nā mea kalapona i ʻoi aku ma mua o 2%. ʻOiai hiki ke loaʻa ka pākēneka kalapona i ka hao hao ma waena o 2 a 6.67, ʻo ka palena kūpono ma waena o 2 a me 4%. He mea nui kēia ma muli o kā lākou mau hiʻohiʻona maikaʻi loa. ʻO nā hao hina hina a me nā hao ductile (i kapa ʻia ʻo nodular cast iron a i ʻole spheroidal graphite iron) ka mea maʻamau i hoʻohana ʻia i loko.hoʻoheheʻe ʻia.

ʻO ka hao ductile he hao nodularized nona ka graphite ma ke ʻano he mau mea liʻiliʻi, poepoe, a puʻunaue maikaʻi ʻia, liʻiliʻi kona hopena nāwaliwali a ʻoi aku ka nui o ka ductility o ia mau hao. Kapa ʻia kēia ʻano hao hao he ductile a iron nodular a i ʻole graphite spheroidal a i ʻole hao SG wale nō. Hiki ke loaʻa kēia ʻano graphite ma ka hoʻohui ʻana i ka magnesium elemental a i ʻole cerium a i ʻole ka hui pū ʻana o nā mea ʻelua i ka hao hoʻoheheʻe ʻia. Hoʻohui ʻia ka Magnesium i ka nui o 0.07 a 0. 10% i ukali ʻia e ka hoʻohui ʻana o ka ferro-silicon e hoʻoikaika i ka graphitization. I ka wā paʻa, kōkua ka magnesium i ka hāʻawi ʻana i ka graphite ma ka metala.

ʻOi aku ka maikaʻi o ka ikaika-a-kaumaha lākiō, ʻoi aku ka maikaʻi o ka mīkini a me ka waiwai o ka hopena kiʻekiʻe. Eia kekahi, hana ʻia nā hoʻoheheʻe hao ductile ma ke kaʻina hoʻolei kahi e hiki ai ke hoʻokō ʻoi aku ka maikaʻi o ke ʻano o ka ʻāpana i hoʻohālikelike ʻia me ka hāʻule forging. No laila, nui nā ʻāpana e like me nā crank shafts a me nā koʻokoʻo hoʻohui i hana maʻamau ʻia e ka hoʻoheheʻe ʻana.ke hoʻololi hou ʻia nei e ka hao ductile.
