He aha ke kila?
He mea hoʻohuihui hao ke kila a ʻo ke kumu hoʻohuihui nui (nui) ʻo ia ke Kalapona. Eia nō naʻe, aia kekahi mau ʻokoʻa i kēia wehewehe ʻana e like me nā kila interstitial-free (IF) a me nā kila kila ferritic ʻano 409, kahi i manaʻo ʻia ai ke kalapona he mea haumia.
He aha ka Alloy?
Ke hui ʻia nā mea like ʻole i nā nui liʻiliʻi i loko o ke kumu, ua kapa ʻia ka huahana hopena he hui hao o ke kumu. No laila, he hui hao ke kila no ka mea ʻo ka hao ke kumu (ʻāpana nui) i loko o ke kila a ʻo ke kumu hui hao nui ʻo ia ke Kalapona. Hoʻohui pū ʻia kekahi mau mea ʻē aʻe e like me Manganese, Silicon, Nickel, Chromium, Molybdenum, Vanadium, Titanium, Niobium, Aluminum, a me nā mea ʻē aʻe i nā nui like ʻole e hana i nā papa (a i ʻole nā ʻano) like ʻole o ke kila.
ʻO Jindalai (Shandong) Steel Group Co., Ltd. kahi loea a me ka mea hoʻolako alakaʻi i nā kaola/paipu/coils/plates kila a me ke kila kila ʻole. E hoʻouna mai i kāu nīnau a e hauʻoli mākou e kūkākūkā me ʻoe ma ke ʻano loea.
He aha nā ʻano kila like ʻole?
Ma muli o nā ʻano kemika, hiki ke hoʻokaʻawale ʻia ke kila i ʻehā (04) mau ʻano kumu:
● Ke kila kalapona
● Ke kila kila
● Ke kila kila
● Mea Hana Kila
1. Ke kila kalapona:
ʻO ke kila kalapona ke kila i hoʻohana nui ʻia ma nā ʻoihana a ʻoi aku ma mua o 90% o ka huina o ka hana kila. Ma muli o ka nui o ke kalapona, ua hoʻokaʻawale hou ʻia nā kila kalapona i ʻekolu mau pūʻulu.
● Ke kila kalapona haʻahaʻa/kila palupalu
● Ke kila kalapona waena
● Ke kila kalapona kiʻekiʻe
Aia ka nui o ke kalapona ma ka papa ma lalo nei:
| ʻAʻole. | ʻAno kila kalapona | Pakeneka o ke Kalapona |
| 1 | Ke kila kalapona haʻahaʻa/kila palupalu | A hiki i ka 0.25% |
| 2 | Ke kila kalapona waena | 0.25% a i 0.60% |
| 3 | Ke kila kalapona kiʻekiʻe | 0.60% a i 1.5% |
2. Kila kila:
ʻO ke kila kila he kila huila nona ka 10.5% Chromium (Ka palena iki). Hōʻike ke kila kila i nā waiwai kūpaʻa i ka pala, ma muli o ka hoʻokumu ʻia ʻana o kahi papa lahilahi loa o Cr2O3 ma luna o kona ʻili. Ua kapa ʻia kēia papa ʻo ka papa passive. ʻO ka hoʻonui ʻana i ka nui o Chromium e hoʻonui hou aku i ke kūpaʻa i ka pala o ka mea. Ma waho aʻe o Chromium, hoʻohui pū ʻia ʻo Nickel a me Molybdenum e hāʻawi i nā waiwai i makemake ʻia (a i ʻole i hoʻomaikaʻi ʻia). Loaʻa i ke kila kila nā ʻano like ʻole o ke Carbon, Silicon, a me Manganese.
Ua hoʻokaʻawale hou ʻia nā kila kila e like me;
1. Nā kila kila Ferritic
2. Nā kila kila Martensitic
3. Nā kila kila Austenitic
4. Nā kila kila Duplex
5. Nā kila kila paʻakikī-Pū (PH)
● Ke kila kila Ferritic: ʻO nā kila Ferritic i hana ʻia me nā mea hao-Chromium me nā ʻano kristal cubic i waenakonu o ke kino (BCC). He magnetic kēia mau mea a ʻaʻole hiki ke hoʻopaʻakikī ʻia e ka mālama wela akā hiki ke hoʻoikaika ʻia e ka hana anu.
● Ke kila kila Austenitic: ʻOi aku ka maikaʻi o ke kūpaʻa ʻana o nā kila Austenitic i ka pala. ʻAʻole ia he magnetic a ʻaʻole hiki ke mālama ʻia i ka wela. Ma ke ʻano laulā, hiki ke hoʻoheheʻe ʻia nā kila austenitic.
● Ke kila kila Martensitic: He ikaika loa a paʻakikī nā kila kila Martensitic akā ʻaʻole i kūpaʻa i ka pala e like me nā papa ʻelua ʻē aʻe. He maʻalahi loa kēia mau kila i ka mīkini, magnetic, a hiki ke mālama ʻia i ka wela.
● Nā kila kila Duplex: ʻO ke kila kila Duplex he microstructure ʻelua-paepae i haku ʻia me nā hua kila ferritic a me austenitic (ʻo ia hoʻi ʻo Ferrite + Austenite). ʻOi aku ka ikaika o nā kila Duplex ma mua o nā kila kila austenitic a i ʻole ferritic.
● Nā Kila Kila Paʻakikī-Pū (PH): Loaʻa i nā Kila Kila Paʻakikī-Pū (PH) ka ikaika kiʻekiʻe loa ma muli o ka paʻakikī ʻana o ka ua.
3. Ke kila kila
I loko o ke kila kila, hoʻohana ʻia nā ʻano like ʻole o nā mea hoʻohuihui, e hoʻokō i nā waiwai i makemake ʻia (i hoʻomaikaʻi ʻia) e like me ka weldability, ductility, machinability, ikaika, hardenability a me ke kūpaʻa ʻana i ka corrosion, a pēlā aku. ʻO kekahi o nā mea hoʻohuihui i hoʻohana nui ʻia a me ko lākou hopena penei;
● Manganese – Hoʻonui i ka ikaika a me ka paʻakikī, hoʻemi i ka ductility a me ka weldability.
● Silika – Hoʻohana ʻia ma ke ʻano he mau mea hoʻohemo ʻona i hoʻohana ʻia i ke kaʻina hana kila.
● Phosphorus – Hoʻonui i ka ikaika a me ka paʻakikī a hoʻemi i ka ductility a me ka notch impact toughness o ke kila.
● Sulfur –Hoʻemi i ka ductility, ka paʻakikī o ka hopena notch, a me ka weldability. Loaʻa ma ke ʻano o nā inclusions sulfide.
● Keleawe – hoʻomaikaʻi i ke kūpaʻa ʻana i ka pala.
● Nickel – Hoʻonui i ka paʻakikī a me ka ikaika o nā kila.
● Molybdenum – Hoʻonui i ka paʻakikī a hoʻoikaika i ke kūpaʻa kolo o nā kila haʻahaʻa.
4. Mea Hana Kila
He kiʻekiʻe ka nui o ke kalapona o nā kila mea hana (0.5% a 1.5%). ʻOi aku ka nui o ke kalapona e hāʻawi i ka paʻakikī a me ka ikaika. Hoʻohana nui ʻia kēia mau kila e hana i nā mea hana a me nā make. Loaʻa i ke kila mea hana nā ʻano nui like ʻole o ka tungsten, cobalt, molybdenum, a me vanadium e hoʻonui i ke kūpaʻa wela a me ke komo ʻana, a me ke kūpaʻa o ka metala. ʻO kēia ka mea e kūpono loa ai nā kila mea hana no ka hoʻohana ʻana ma ke ʻano he mau mea hana ʻoki a me ka wili.
Ua piha ʻo Jindalai Steel Group i nā huahana kila maikaʻi loa ma ka ʻoihana. Hiki iā Jindalai ke kōkua iā ʻoe e koho i nā mea kila kūpono e hōʻoia i ka loaʻa ʻana o kāu mea e pono ai i ka wā hikiwawe loa i ka wā e kūʻai ai. Inā kokoke mai ke kūʻai ʻana i nā mea kila, e noi i kahi ʻōlelo kūʻai. E hāʻawi mākou i hoʻokahi e loaʻa koke iā ʻoe nā huahana āu e pono ai.
