NM400 /NM 450 komo i ka pā kila pale
ʻO NM450 kahi pā lole ikaika kiʻekiʻe.
Kapa inoa: N no ke kū'ē (nai), ʻo M ka leka pinyin mua o nā huaʻōlelo Kina ʻelua no ka wili ʻana (mo),
a he 450 ka awelika o ka paakiki Brinell o keia pa kila
Hoʻomaʻamaʻa wela: ka wela wela kiʻekiʻe, hoʻopau + hoʻoulu (quenching and tempering)
Noi: Hoʻohana nui ʻia ka pā kila kila NM450 i nā mīkini mining, nā mīkini eli lanahu,
nā mīkini pale kaiapuni, nā mīkini hana, a me nā mea ʻē aʻe, a hoʻohana mau ʻia e like me ka ikaika kiʻekiʻe
ke kila kila me ka ikaika hua ≥850MPa.
Hana: ʻO ia ka mea nui e hāʻawi i ka pale i nā manawa a i ʻole nā ʻāpana e pono ai ke pale aku, i hiki ai ke ola o
ʻoi aku ka lōʻihi o nā mea hana, hoʻemi ʻia ka downtime mālama ʻia e ka mālama ʻana, a me ka hoʻopukapuka kālā
ua hoemi like ia.
Hana: ʻOi aku ka hua ma mua o 950, a ʻo ka ikaika tensile ʻo 1180.
NM450 pili i nā kūlana haole a me nā māka JFE:NK-EH450/HARDOX450/DILLDUR:450V

1) Nā mīkini hana a me nā mea hana: loader, bulldozer, excavator, bakeke pā, ʻaoʻao ʻaoʻao pā,
pāpaʻi lalo o ka bākeke, ka ʻili, a me ka pā sill.
2) Hoʻouka a hoʻokuʻu i nā mīkini a me nā mea hana: wehe ʻana i ka paʻi kaulahao wili, ka pā lining hopper, hopu i ka pā lau,
kaʻa kaʻa kaʻa liʻiliʻi liʻiliʻi
3) Nā mīkini hana a me nā mea hana: ka pā niho o ka mea hoʻoheheʻe sima, ka pā uhi ʻana o ka mea hoʻoheheʻe sima, ka pā uhi o
papahele hui ʻana, papa ʻili o ka ʻohi lepo
4) ʻO nā mīkini metala a me nā mea hana: ʻo ka hao hao sintering e lawe ana i ka kuʻekuʻe lima, ka hao hao sintering machine lining,
kaʻa ʻōpala
5) ʻO nā mīkini a me nā mea hana mining: ʻo, ka ʻili pōhaku pōhaku, nā lau.
6) Nā lako mīkini ʻē aʻe: pahu wili lepo, nā ʻili, nā ʻāpana pale ʻaʻahu o nā mīkini awa like ʻole
7) ʻO nā lako mana wela: ka pā hale wili lanahu, hopper lanahu, paipu hoʻohele lanahu, mea hāʻawi lanahu.
