Pehea e hiki ai iaʻu ke ana i ke ʻano ʻino o ka ʻili?
Hiki iā ʻoe ke helu i ke ʻano oka ʻili ma ke ana ʻana i nā piko ʻili a me nā awāwa ma kēlā ʻaoʻao. ʻIke pinepine ʻia ke ana ʻo 'Ra,' ʻo ia hoʻi ʻo 'Roughness Average.' ʻOiai ʻo Ra kahi ʻāpana ana pono loa. He kōkua nō hoʻi e hoʻoholo i ka hoʻokō ʻana o kahi huahana a ʻāpana paha me nā kūlana ʻoihana like ʻole.
Hana ʻia kēia ma ka hoʻohālikelike ʻana me nā palapala hoʻopau ʻili.
He aha ka ʻokoʻa ʻana o Ra a me Rz i ka papa ʻaina ʻino?
ʻO Ra kahi ana o ka lōʻihi ma waena o nā piko a me nā awāwa. He ana nō hoʻi ia i ka ʻeʻe ʻana mai ka laina mean ma ka ʻili i loko o ka lōʻihi hoʻohālike.
Ma kekahi ʻaoʻao, kōkua ʻo Rz i ke ana ʻana i ka mamao kūpaʻa ma waena o ka piko kiʻekiʻe a me ke awāwa haʻahaʻa. Hana ʻo ia i kēia i loko o ʻelima mau laʻana i ka lōʻihi a laila hoʻokaʻawale i nā mamao i ana ʻia.
He aha nā mea e pili ana i ka hoʻopau ʻana i ka ʻili?
Hoʻopili kekahi mau mea i ka hoʻopau ʻana i ka ʻili. ʻO ka mea nui o kēia mau mea ʻo ia ka hana hana. ʻO nā kaʻina hana mīkini e like me ka huli ʻana, ka wili, a me ka wili ʻana e hilinaʻi ʻia i nā kumu he nui. No laila, ʻo nā mea e pili ana i ka hoʻopau ʻana i ka ʻili

Kaʻina hana o nā paipu pololei
ʻOkoʻa ka ʻenehana hana a me ka hana ʻana o nā paipu kūpono kila kila maikaʻi loa mai nā paipu kuʻuna maʻamau. Hoʻopuka pinepine ʻia nā paipu paipu kuʻuna ʻole e ʻelua-roll cross-roll hot perforation, a ʻo ke kaʻina hana o nā paipu maʻamau e hoʻohana i ke kaʻina hana kaha kiʻi. Hoʻohana maʻamau ʻia nā paipu pololei kila kila i nā mea kani pololei a i ʻole nā mea lapaʻau. ʻAʻole wale ke kiʻekiʻe o nā kumukūʻai, akā hoʻohana pinepine ʻia lākou i nā lako kī a me nā mea kani. No laila, kiʻekiʻe loa nā koi no ka mea, ka pololei a me ka hoʻopau ʻana o ka ʻili o nā paipu kila kila.
Hoʻopuka pinepine ʻia nā pahu pahu o nā mea paʻakikī i ka hana kiʻekiʻe e ka extrusion wela, a ʻo ka hana ʻana o nā paipu e hana mau ʻia e ka ʻōwili anu. Hōʻike ʻia kēia mau kaʻina hana e ke kiʻekiʻe kiʻekiʻe, ka nui o ka plastic deformation, a me nā ʻano hoʻolālā paipu maikaʻi, no laila ua hoʻohana ʻia.
ʻO ka maʻamau, ʻo nā paipu kila kuhiliʻole 301, 304 kila kila, 316 kila kila, 316L kila kila, 310S kila kila. ʻO ka mea maʻamau, ʻoi aku ka nui o nā mea NI8 i hana ʻia, ʻo ia hoʻi, nā mea ma luna o 304, a ʻaʻole i hana ʻia nā paipu kila kila me nā mea haʻahaʻa.
He mea maʻamau ke kāhea ʻana i ka 201 a me ka 202 stainless iron, no ka mea, he magnetic a loaʻa ka hoihoi i nā magnet. ʻAʻole magnetik ka 301, akā he magnetic ma hope o ka hana anu a loaʻa iā ia ka hoihoi i nā magnet. ʻO 304, 316 ʻaʻohe magnetik, ʻaʻohe mea hoihoi i nā magnet, a ʻaʻole pili i nā magnet. ʻO ke kumu nui inā he magnetic a ʻaʻole paha, ʻo ia ka mea i loaʻa i ka chromium, nickel a me nā mea ʻē aʻe i nā ʻāpana like ʻole a me nā hale metallographic. ʻO ka hoʻohui ʻana i nā hiʻohiʻona i luna, he ala kūpono hoʻi ia e hoʻohana ai i nā magnets e hoʻoholo ai i ka maikaʻi o ke kila kila, akā ʻaʻole ʻepekema kēia ʻano, no ka mea i ke kaʻina hana o ke kila kila, aia nā kaha kiʻi anuanu, kiʻi wela, a ʻoi aku ka maikaʻi ma hope- lapaʻau, no laila ua emi ka magnetism a i ʻole. Inā maikaʻi ʻole, ʻoi aku ka nui o ka magnetism, ʻaʻole hiki ke hōʻike i ka maʻemaʻe o ke kila kila. Hiki i nā mea hoʻohana ke noʻonoʻo mai ka hoʻopili ʻana a me ke ʻano o nā paipu kila kuhiliʻole pololei: ʻākala, ʻano mānoanoa like ʻole, a inā he mau ʻili ma ka ʻili.
He mea koʻikoʻi nō hoʻi ka ʻōwili a me ke kaha kiʻi ʻana o ka hana paipu. No ka laʻana, ʻaʻole kūpono ka wehe ʻana i nā lubricants a me nā oxides surface i ka extrusion, kahi e hoʻopilikia nui ai i ka pololei a me ka maikaʻi o ka ʻili o nā paipu kūpono.
