KUMUKUAI O KA PONO HAAHAA
• Ka hana ma luna o 20% e kū'ē i nā kiʻi kalapona kiʻekiʻe
• ʻO ka liʻiliʻi o ka hoʻohana ʻana i nā mīkini a me nā mea hana ma muli o ka nui o ka absorption o ka ikehu i nā hopena i loko o nā ʻāpana
• Nā ʻāpana kīnā ʻole i hana ʻia e ka hoʻomaʻamaʻa wela, nā haʻi a i ʻole nā māwae micro
HOOMAIKAI I KE AINA
• Hoemi pauda
• E hōʻoiaʻiʻo ʻo Bainitic microstructure ʻaʻole lākou e haki i ka wā o kona ola pono
IKE AUPUNI
ʻO ke ʻano o ka pana kila kalapona haʻahaʻa e like me ka spherical.Hiki ke loaʻa ka liʻiliʻi o nā elongated, deformed particle me nā pores, slag a lepo paha.
ʻAʻole pili kēia i ka hana o ka pana, hiki ke hōʻoia ʻia ma ke ana ʻana i kāna hana ma ka mīkini.
PAʻakikī
Hāʻawi ka bainitic microstructure i kahi kiʻekiʻe o ka paʻakikī.Aia ka 90% o nā ʻāpana ma waena o 40 - 50 Rockwell C.
ʻO ke kalapona haʻahaʻa i ke kaulike me ka manganese e hōʻoiaʻiʻo i kahi ola lōʻihi o nā ʻāpana, pēlā e hoʻomaikaʻi ai i ka maʻemaʻe o nā ʻāpana, ʻoiai me ka hana mechanical e hoʻonui ai i ko lākou paʻakikī.
Hoʻopili nui ʻia ka ikehu o ka pana ʻana e nā ʻāpana, no laila e hōʻemi ana i ka lole o ka mīkini.
KA HANA KIEKIE
ʻO ka hoʻohana ʻana i ka pana kila kalapona haʻahaʻa he ākea no nā mīkini i loaʻa nā turbines o 2500 a 3000 RPM a me nā wikiwiki o 80 M / S.
No nā mea hana hou e hoʻohana ana i nā turbines 3600 RPM a me nā wikiwiki o 110 M / S, pono kēia e hoʻonui i ka huahana.
