ʻO ka hana ʻana o ka ʻili o ka pepa kila kila he NO.1, 2B, No. 4, HL, No. 6, No. 8, BA, TR paʻakikī, Rerolled bright 2H, polishing bright a me nā ʻili ʻē aʻe, a pēlā aku.

NO.1: ʻO ka ʻili No. 1 e pili ana i ka ʻili i loaʻa ma o ka mālama wela a me ka pickling ma hope o ka ʻōwili wela ʻana o ka pepa kila kila. ʻO ia ke wehe ʻana i ka unahi ʻeleʻele oxide i hana ʻia i ka wā o ka ʻōwili wela a me ka mālama wela ʻana ma o ka pickling a i ʻole nā ​​​​ʻano mālama like. ʻO kēia ka hana ʻili No. 1. He keʻokeʻo kālā a matt ka ʻili No. 1. Hoʻohana nui ʻia i nā ʻoihana kūpaʻa wela a me ka pale ʻana i ka corrosion ʻaʻole pono ka ʻōlinolino o ka ʻili, e like me ka ʻoihana waiʻona, ka ʻoihana kemika a me nā ipu nui.

2B: ʻOkoʻa ka ʻili o 2B mai ka ʻili 2D no ka mea ua hoʻomaʻemaʻe ʻia me kahi wili laumania, no laila ʻoi aku ka mālamalama ma mua o ka ʻili 2D. ʻO ka waiwai ʻoʻoleʻa o ka ʻili Ra i ana ʻia e ka mea hana he 0.1～0.5μm, ʻo ia ke ʻano hana maʻamau. ʻO kēia ʻano ʻili pepa kila kila ka mea maʻalahi loa, kūpono no nā kumu maʻamau, kahi i hoʻohana nui ʻia i nā ʻoihana kemika, pepa, petroleum, lāʻau lapaʻau a me nā ʻoihana ʻē aʻe, a hiki ke hoʻohana ʻia ma ke ʻano he paia pale hale.

ʻO ka hoʻopau paʻakikī TR: Ua kapa ʻia hoʻi ke kila kila kila paʻakikī. ʻO kona mau ʻano kila he 304 a me 301, hoʻohana ʻia lākou no nā huahana e pono ai ka ikaika a me ka paʻakikī kiʻekiʻe, e like me nā kaʻa kaʻaahi, nā kāʻei conveyor, nā pūnāwai a me nā gaskets. ʻO ke kumumanaʻo, ʻo ia ka hoʻohana ʻana i nā ʻano paʻakikī hana o ke kila kila austenitic e hoʻonui i ka ikaika a me ka paʻakikī o ka papa kila ma o nā ʻano hana anu e like me ka ʻōwili ʻana. Hoʻohana ka mea paʻakikī i kekahi mau pakeneka a i kekahi mau ʻumi pakeneka o ka ʻōwili mālie e pani i ka palahalaha mālie o ka ʻili kumu 2B, a ʻaʻohe annealing e hana ʻia ma hope o ka ʻōwili ʻana. No laila, ʻo ka ʻili paʻakikī TR o ka mea paʻakikī ka ʻili ʻōwili ma hope o ka ʻōwili anu.

ʻŌwili Hou ʻia ka ʻĀlohilohi 2H: Ma hope o ke kaʻina hana ʻōwili. e hana ʻia ka pepa kila kila i ka annealing ʻālohilohi. Hiki ke hoʻomaʻalili koke ʻia ke kaha e ka laina annealing hoʻomau. ʻO ka wikiwiki o ka huakaʻi o ka pepa kila kila ma ka laina ma kahi o 60m ~ 80m / min. Ma hope o kēia kaʻina hana, e ʻōwili hou ʻia ka ʻili i ka ʻālohilohi 2H.

Helu 4: ʻO ka ʻili o ka Helu 4 he ʻili i hoʻopili maikaʻi ʻia e ʻoi aku ka mālamalama ma mua o ka ʻili o ka Helu 3. Loaʻa nō hoʻi ia ma ka hoʻopili ʻana i ka papa kila kila i ʻōwili anu ʻia me ka ʻili 2 D a i ʻole 2 B ma ke kumu a me ka hoʻopili ʻana me ke kāʻei abrasive me ka nui o ka palaoa o 150-180 # ʻIli i mīkini ʻia. ʻO ka waiwai ʻo Ra o ka ʻili i ana ʻia e ka mea hana he 0.2～1.5μm. Hoʻohana nui ʻia ka ʻili NO.4 i nā lako hale ʻaina a me nā lako kīhini, nā lako lapaʻau, nā mea hoʻonaninani hale, nā ipu, a pēlā aku.

HL: Ua kapa pinepine ʻia ka ʻili HL he hairline finish. Ua ʻōlelo ke kūlana JIS Kepanī e hoʻohana ʻia ke kāʻei abrasive 150-240# e hoʻopili i ka ʻili abrasive e like me ka hairline hoʻomau i loaʻa. Ma ke kūlana GB3280 o Kina, ua maopopo ʻole nā ​​​​lula. Hoʻohana nui ʻia ka hoʻopau ʻili HL no ka hoʻonaninani hale e like me nā elevators, escalators, a me nā facades.

Helu 6: Ua hoʻokumu ʻia ka ʻili o Helu 6 ma luna o ka ʻili o Helu 4 a ua hoʻowali hou ʻia me kahi pulumu Tampico a i ʻole kahi mea abrasive me ka nui o ka ʻāpana o W63 i kuhikuhi ʻia e ke kūlana GB2477. He ʻōlinolino metala maikaʻi kēia ʻili a he hana palupalu. He nāwaliwali ka ʻōlinolino a ʻaʻole hōʻike i ke kiʻi. Ma muli o kēia waiwai maikaʻi, kūpono loa ia no ka hana ʻana i nā paia pale hale a me nā mea hoʻonaninani fringe hale, a hoʻohana nui ʻia hoʻi e like me nā lako kīhini.

BA: ʻO BA ka ʻili i loaʻa ma o ka mālama wela ʻālohilohi ma hope o ka ʻōwili anu. ʻO ka mālama wela ʻālohilohi ka annealing ma lalo o kahi lewa pale e hōʻoiaʻiʻo ana ʻaʻole i oxidized ka ʻili e mālama i ka ʻōlinolino o ka ʻili i ʻōwili anu ʻia, a laila e hoʻohana i kahi ʻōwili smoothing kiʻekiʻe no ka hoʻohālikelike ʻana i ka mālamalama e hoʻomaikaʻi i ka ʻālohilohi o ka ʻili. Ua kokoke kēia ʻili i kahi hoʻopau aniani, a ʻo ka waiwai ʻo Ra roughness i ana ʻia e ka mea hana he 0.05-0.1μm. Loaʻa i ka ʻili BA kahi ākea o nā hoʻohana a hiki ke hoʻohana ʻia e like me nā lako kīhini, nā lako hale, nā lako lapaʻau, nā ʻāpana kaʻa a me nā mea hoʻonaninani.

Helu 8: ʻO ka Helu 8 kahi ʻili i hoʻopau ʻia e ke aniani me ka reflectivity kiʻekiʻe loa me ka ʻole o nā hua abrasive. Ua kapa pū ʻia ka ʻoihana hana hohonu kila kila he mau papa 8K. Ma ke ʻano laulā, hoʻohana ʻia nā mea BA ma ke ʻano he mea maka no ka hoʻopau ʻana i ke aniani ma o ka wili ʻana a me ka polishing wale nō. Ma hope o ka hoʻopau ʻana i ke aniani, he kiʻi ka ʻili, no laila hoʻohana nui ʻia ia i ka hoʻonaninani puka hale a me ka hoʻonaninani o loko.

He mea paʻa a maʻalahi hoʻi ke kila kila me nā ʻano hana ʻoihana like ʻole, mai ke kūkulu ʻana a i nā lako kīhini. He mea nui loa ka ʻili o ka papa kila kila no ka mea e pili pololei ana ia i ka ikaika, ke ʻano a me ke kūpaʻa ʻana i ka pala o ka mea.

Hana ʻia ke kila kila ma ka hoʻohui ʻana i ka hao, chromium, a me kekahi mau metala ʻē aʻe. ʻO ke kūpaʻa ʻana o ke kila kila ma muli o ka hoʻokumu ʻia ʻana o kahi papa pale lahilahi o ka chromium oxide ma luna o ka ʻili. Hoʻokumu ʻia kēia papa oxide, i kapa ʻia he kiʻi passivation, ke hana ka chromium me ka oxygen i ka lewa a i ʻole ka wai.

ʻO ke ʻano o ka ʻili hana ʻole ma nā ʻili kila kila e pili ana i ke ʻano o ka hana ʻana, ka hana ʻana a me ka mālama ʻana i ka metala. ʻO kēlā me kēia hemahema ma ka ʻili, e like me nā ʻōpala, nā dents a i ʻole ka ʻoʻoleʻa, hiki ke hoʻopilikia i ka ʻili, e ʻae ana i ka makū a me ka oxygen e komo i loko o ka metala a hana i ka pala.

No ka hōʻoia ʻana i ka ʻili kila kila maikaʻi loa, hiki ke hoʻohana ʻia nā kaʻina hana like ʻole. ʻO ka passivation kahi ʻenehana e pili ana i ka hoʻomaʻemaʻe ʻana i ka metala a laila e hōʻike ana iā ia i kahi kaʻina hana kemika i kāohi ʻia e hoʻonui ai i ka mānoanoa o kahi ʻili hana ʻole. ʻO ka electropolishing kekahi kaʻina hana no ka hoʻomaʻemaʻe ʻana a me ka poli ʻana i ka ʻili o ke kila kila e wehe i nā hemahema o ka ʻili.

He mea nui nō hoʻi ka hoʻomaʻemaʻe mau ʻana no ka mālama ʻana i ka maikaʻi o nā ʻili kila kila. Hoʻopau ka hoʻomaʻemaʻe ʻana i ka lepo, ka lepo a me nā mea haumia ʻē aʻe e hiki ai ke hoʻoulu i ka pala. Manaʻo ʻia e hoʻohana i kahi mea hoʻomaʻemaʻe ʻaʻole e abrasive a me kahi lole palupalu e pale i ka ʻili metala i ka wā e hoʻomaʻemaʻe ai.

Hiki ke hoʻohana ʻia nā uhi ʻili e pale hou aku i ka ʻili o ka papa kila kila. Hāʻawi kēia mau uhi i ka pale hou aku e kūʻē i ka pala mai nā kaiapuni ʻino, nā kemika a me ke aniau.

I ka hōʻuluʻulu ʻana, ʻo ka ʻili o ka papa kila kila kahi mea nui e hoʻopilikia ana i ka hana a me ke ola o ka mea. ʻO ka mālama mau ʻana a me ka hoʻomaʻemaʻe ʻana, a me ka hoʻohana ʻana i nā ʻano hana passivation a i ʻole electropolishing hiki ke hōʻoia i ka ʻili kila kila maikaʻi loa. Ke mālama pono ʻia, hiki i ka papa kila kila ke hāʻawi i ka lōʻihi a me ka nani no nā ʻano hana ʻoihana like ʻole.
