ʻO ke kila kila a me ka mīkini CNC
ʻO ke kila kila he metala nui loa a hoʻohana pinepine ʻia no ka CNC Machining a me ka huli ʻana o CNC i ka aerospace, automotive a me nā ʻoihana moana. Uaʻikeʻia ke kila kila no kona kū'ēʻana i ka corrosion a me nā'āpana likeʻole a me nā māka o ke kila kila i loaʻa, aia nāʻano likeʻole o nā noi a me nā hihia hoʻohana.
ʻElima mau ʻāpana maʻamau o ke kila kila me nā mea hoʻohui like ʻole a me nā hale waiwai.
- Austenitic Stainless Steel
- ʻO Ferritic Stainless Steel
- He kila kila ʻole Martensitic
- Ua Paʻa Paʻa Steel
- He kila ʻili ʻole (Austenitic-Ferritic)
Austenitic kila
Hoʻohana nui ʻia nā kila kila Austenitic no nā huahana e koi ai i ka pale ʻana i ka corrosion ikaika. Hoʻohana pinepine nā huahana hale, ʻoihana a me nā hale kūkulu hale i ke kila kila austenitic. Hiki i kēia mau mea ke komo:
1.Nuts a me nā kī a me nā mea paʻa ʻē aʻe;
2. Mea hana meaʻai;
3.Industrial Gas Turbines.
Uaʻikeʻia nā kila kila Austenitic no ko lākou machinability a me ka weldability,ʻo ia hoʻi, hoʻohana pinepineʻia lākou i ka CNC machining. Ma muli o kona ʻano crystalline nui, ʻaʻole hiki ke hoʻopaʻakikī ʻia ke kila stainless austenitic e ka wela, a hoʻolilo iā lākou i non-magnetic. Loaʻa nā māka kaulana ʻo 304 a me 316, a aia ma waena o 16 a me 26 pākēneka chromium.
Ke kila ferritic
ʻO ke kila kila Ferritic ma kahi o 12% chromium. He ʻokoʻa ia mai nā ʻano kila kuhili ʻē aʻe ma muli o kona ʻano kemika a me kāna ʻano molecular grain structure. ʻAʻole like me ke kila austenitic, ʻo ke kila ferritic kahi ʻano magnetic ma muli o kona kino i hoʻokumu ʻia i ka cubic grain structure. Me ka haʻahaʻa haʻahaʻa o ka corrosion a me ka wela wela ma mua o ke kila austenitic, hoʻohana maʻamau ia no nā ʻāpana kaʻa a me nā mea kīhini.
Hāʻawi ke kila Ferritic i kahi kiʻekiʻe o ke kūʻē ʻana i ke koʻikoʻi i ka haki ʻana. ʻO kēia ka mea i koho nui ʻia o ke kila no nā kaiapuni kahi i loaʻa ai ka chloride. Hiki ke hoʻohaʻahaʻa i ke kila ke hoʻohaʻahaʻa i ke kila inā ʻike ʻia i kahi pōʻino, ʻoi aku ka nui, ke ʻike ʻia i nā chlorides.
Ke kila martensitic
ʻO Martensite kahi ʻano kila paʻakikī, a ʻo kona mau waiwai he kila ia e hiki ke mālama ʻia i ka wela a paʻakikī, akā naʻe, ua hoʻemi ʻo ia i ka pale kemika, ke hoʻohālikelike ʻia me nā kila austenitic. ʻO nā pōmaikaʻi o ke kila martensitic ʻo ia ka mea e hāʻawi ai i kahi kumukūʻai haʻahaʻa, metala paʻakikī ea me ke kūpaʻa corrosion haʻahaʻa, maʻalahi e hana, me ka liʻiliʻi o ka chromium maʻiʻo o 10.5%.
ʻO ka hoʻohana ʻana i ke kila stainless martensitic penei:
1. ʻOki
2. Nā ʻāpana kaʻa
3.Steam, kinoea a me jet turbine blades
4.Valele
5. Nā mea hana ʻokiʻoki
Ua Paʻa Paʻa Paʻa
ʻO ke kila paʻakikī ka ua ʻoi aku ka ikaika o ke kila, hiki ke mālama ʻia i ka wela a he kūpaʻa maikaʻi loa. Ma muli o kēia hoʻohana nui ʻia no nā ʻāpana aerospace, kahi e pono ai ka lōʻihi a me ka hilinaʻi mai ka ʻāpana.
Hoʻohana pū ʻia ke kila PH i ka ʻaila, kinoea a me nā ʻoihana nuklea. ʻO kēia no ka mea hāʻawi ia i ka hui pū ʻana o ka ikaika kiʻekiʻe akā ma ke ʻano he haʻahaʻa haʻahaʻa akā hiki ke hana o ka paʻakikī. ʻO nā māka kaulana loa o nā kila paʻakikī o ka ua he 17-4 PH a me 15-5 PH.
Hoʻohana maʻamau no ke kila paʻakikī PH:
1. Na pahi
2. Nā pū
3. Nā mea hana ʻokiʻoki
4. Nā mea hana lima
Duplex Steel Steel
ʻO nā kila kuhiliʻole Duplex, i kekahi manawa i kapa ʻia ʻo austenitic-ferritic stainless steel he ʻelua-phase metallurgical structures. ʻO ia hoʻi, ʻo ka duplex stainless steel aia nā austenitic a me nā pae ferritic. ʻOi aku ka ikaika o nā kila stainless duplex ma mua o ke kila kila austenitic maʻamau a loaʻa ka pale corrosion hou.
He haʻahaʻa ka molybdenum a me ka nickel ma ka papa Duplex e hiki ke hōʻemi i nā kumukūʻai ke hoʻohālikelike ʻia me nā māka austenitic. No laila, hoʻohana pinepine ʻia nā alloy duplex i nā noi ʻoihana kaumaha e like me ka ʻoihana petrochemical.
Nā mea e noʻonoʻo ai i ke koho ʻana i kahi papa kila kuhili ʻole
Nui nā kumu e pono e noʻonoʻo ʻia i ke koho ʻana i kahi mea no kēlā me kēia papahana. Me ka nui o nā mākau kila kila ʻokoʻa i loaʻa, hiki ke paʻakikī ke hōʻemi i kāu koho. Eia nō naʻe, inā ʻoe e noʻonoʻo i kēia mau mea, pono ʻoe i kahi kūlana e hoʻoholo ai i ka papa i kūpono iā ʻoe.
Ka ikaika
ʻO ka ikaika pinepine ka mea nui i ka hoʻoholo ʻana i ka mea maikaʻi loa no kāu papahana. Paipai mākou i ka hoʻomohala ʻana i ka ʻike o nā ikaika a me nā ukana e ʻike ʻia e kāu mau ʻāpana a hoʻohālikelike i kēia me nā ʻano ikaika tensile i hāʻawi ʻia. E kōkua kēia iā ʻoe e hoʻopau i nā mea i hāʻawi ʻole i ka ikaika i koi ʻia.
Hoʻomaʻamaʻa Wela
Inā loaʻa iā ʻoe nā koi paʻakikī no kāu mau ʻāpana, makemake paha ʻoe e noʻonoʻo i ka mālama wela. E hoʻomanaʻo i ka hoʻomaikaʻi ʻana o ka hoʻomaʻamaʻa wela i ka paʻakikī o kāu mau ʻāpana, hiki mai paha kēia ma ka lilo o nā waiwai mechanical ʻē aʻe. E hoʻomanaʻo hoʻi ʻaʻole hiki ke mālama ʻia nā kila stainless austenitic, no laila e hoʻopau i kēia ʻāpana mai kāu koho waiwai.
Magnetism
Ma kekahi mau papahana, he mea koʻikoʻi ia e noʻonoʻo ai inā he magnetic a ʻaʻole paha. E hoʻomanaʻo i ke kila austenitic he non-magnetic ma muli o kona microstructure.
Koina
Inā ʻo ke kumukūʻai ka mea nui loa no kāu papahana, e hoʻomanaʻo. Eia naʻe, ʻo ke kumu kūʻai waiwai hoʻokahi wale nō ʻāpana o ke kumukūʻai holoʻokoʻa. E ho'āʻo e hōʻemi i ke kumukūʻai ma ka hoʻemi ʻana i ka nui o nā hana mīkini a hoʻomaʻamaʻa i kāu mau ʻāpana e like me ka hiki.
Loaʻa i ka papa
Ke hoʻonohonoho nei i kahi ʻōlelo me nā ʻoihana mīkini CNC e like me mākou, e nānā e ʻike i nā māka kila kila a lākou e hāʻawi ai; aia paha nā māka maʻamau a lākou e hoʻopaʻa ai a hiki ke loaʻa maʻalahi. E ho'āʻo e hōʻole i ka wehewehe ʻana i nā māka niche a i ʻole nā mea branded no ka mea hiki ke hoʻonui i nā kumukūʻai a me nā manawa alakaʻi.
