Paipu hao hao

ʻO ka paipu hao e pili ana i ka paipu i hoʻolei ʻia e ka hao.Hoʻohana ʻia ka paipu hao hao no ka hoʻolako ʻana i ka wai, ka hoʻoheheʻe ʻana a me nā paipu hoʻoili kinoea, me nā paipu pololei hao a me nā pono paipu.He haʻahaʻa ka ikaika o ka hana.Wahi a nā ʻano hana hoʻoheheʻe ʻokoʻa, ua māhele ʻia i loko o ka paipu hao hoʻomau a me ka paipu hao centrifugal, ma waena o ia mea e hoʻokaʻawale ʻia ai ka paipu hao centrifugal i loko o ke one a me ka metala.Wahi a nā mea like ʻole, ua hoʻokaʻawale ʻia i loko o ka paipu hao hina hina a me ka paipu hao ductile.E like me nā ʻano like ʻole, ua hoʻokaʻawale ʻia i loko o ka interface maʻalahi, flange interface, self-anchor interface, rigid interface, etc.

ʻO ke kumu o ka paipu hao he paipu hao ductile, i kapa ʻia kēia no ka mea he ʻano hao a me ka hana o ke kila.Aia ka graphite i ka paipu hao ductile ma ke ʻano spherical, a ʻo ka nui o ka graphite he 6-7 maʻamau.Pono ka maikaʻi e hoʻomalu i ka pae spheroidization o ka paipu hao i ka pae 1-3, a ʻo ka nui o ka spheroidization ≥80%, no laila ua hoʻomaikaʻi maikaʻi ʻia nā ʻano mechanical o ka mea pono, me ke ʻano o ka hao a me ka hana o ke kila. .Ma hope o ka hoʻopili ʻana, ʻo ke ʻano metallographic o ka paipu hao ductile he ferrite me kahi mea liʻiliʻi o ka pearlite, a maikaʻi nā waiwai mechanical, no laila ua kapa ʻia ʻo ia ka paipu hao hao.
