He kila mākēneki?

Hoʻolauna

Ua ʻike nui ʻia ke kila kila no kona kūpaʻa ʻana a me kona helehelena maikaʻi, akā ʻo ka nīnau i nīnau pinepine ʻia:He kila kuhiliʻole ka magnetic?ʻAʻole pololei ka pane - pili ia i kaʻano ʻanoahale anianio ke kila kila. I loko o kēia alakaʻi, e ʻimi mākou i nā waiwai magnetic o nā māka kila kuhiliʻole like ʻole, e wehewehe i nā kuhi hewa, a kōkua i nā ʻenekinia, nā mea kūʻai aku, a me nā mea DIY e hana i nā koho ʻike.

He aha ka mea e hana ai i kahi mea magnetic?

Ma mua o ka luʻu ʻana i ke kila kila, e noʻonoʻo kākou i ka mea e hoʻoholo ai inā he magnetic ka mea. ʻO kahi meamākiainā hiki ke huki ʻia i ka magnet a i ʻole ka magnetized. Hana ʻia kēia i ka wā i loaʻa ai ka meanā electrons hui ʻolea he aʻano ʻano kristalka mea e hiki ai ke hoʻolikelike i nā kāhuna magnetic.

Hoʻokaʻawale ʻia nā mea i ʻekolu ʻano magnetic:

• Ferromagnetic(ikaika ikaika)

• Paramagnetic(māmā nāwaliwali)

• Diamagnetic(ʻaʻole magnetik)

ʻO ke ʻano o ke kila kila: Ferrite, Austenite, Martensite

ʻO ke kila kila hehao haoi loko o ka chromium a i kekahi manawa nickel, molybdenum, a me nā mea ʻē aʻe. Kona waiwai magnetic pili i konamicrostructure, e hāʻule ana i loko o kēia mau ʻāpana:

1. Austenitic Stainless Steel (Non-Magnetic or Weakly Magnetic)

• Nā Papa Maʻamau: 304, 316, 310, 321

• Hoʻolālā: Kubiki Kauwaena Maka (FCC)

• Magnetic?: ʻAʻole maʻamau, akā, ʻo ka hana anu (e laʻa, ka piko, ka mīkini) hiki ke hoʻoulu i ka magnetism.

ʻO nā kila kila Austenitic nā ʻano mea maʻamau i hoʻohana ʻia i nā lako kīhini, nā paipu, a me nā mea lapaʻau ma muli o ko lākou kūpaʻa maikaʻi a me ka ductility.

2. He kila ʻili ʻole Ferritic (Magnetic)

• Nā Papa Maʻamau: 430, 409,446

• Hoʻolālā: Kubiki-Iwaena o ke Kino (BCC)

• Magnetic?: ʻAe, he mau kila ferritic.

Hoʻohana maʻamau ia i nā ʻāpana kaʻa, nā mea hana hale, a me nā noi ʻoihana kahi e lawa ai ke kūpaʻa corrosion.

3. He kila ʻili ʻole Martensitic (Magnetic)

• Nā Papa Maʻamau: 410, 420, 440C

• Hoʻolālā: Tetragonal Kūwaena-Kino (BCT)

• Magnetic?: ʻAe, ʻo kēia mau mea ikaika loa.

ʻIke ʻia nā kila Martensitic no ko lākou paʻakikī a hoʻohana mau ʻia i nā pahi, nā mea hana ʻoki, a me nā ʻāpana turbine.

ʻO 304 a i ʻole 316 kuhiliʻole kila mākēneki?

ʻO kēia kekahi o nā nīnau i ʻimi nui ʻia. Eia ka hoʻohālikelike wikiwiki:

No laila, inā ʻoe e ʻimi neikila kuhiliʻole magnetic, 304 a me 316 kāu mau koho maikaʻi loa - ʻoi loa i ko lākou kūlana annealed.

No ke aha he mea koʻikoʻi inā ʻo ke kila kuhili ʻole he Magnetic?

He mea koʻikoʻi ka hoʻomaopopo ʻana inā he magnetic ke kila kila kila no:

• Mea hana meaʻai: kahi e hoʻopilikia ai ka magnetism i nā mīkini.

• Nā mea lapaʻau: e like me nā mīkini MRI, kahi e pono ai nā mea non-magnetic.

• Nā mea hoʻohana: no ka launa pū me nā mea hoʻopili magnetic.

• Hana hana ʻoihana: kahi e loli ai ka weldability a i ʻole ka hana mīkini ma muli o ke ʻano.

Pehea e ho'āʻo ai i ke kila kila kila

No ka nānā ʻana inā he magnetic ke kila kila:

1. E hoʻohana i ka magnet- E hoʻopaʻa i ka ʻili. Inā pili paʻa ia, he magnetic.

2. E ho'āʻo i nā wahi like ʻole– Hiki ke hōʻike hou aku ka magnetism i nā wahi welded a i hana anu.

3. E hōʻoia i ka papa- I kekahi manawa, hoʻohana ʻia nā koho haʻahaʻa haʻahaʻa me ka ʻole o ka lepili.

Non-magnetic kuhiliʻole uea kaula Magnetic ho'āʻo

Ua hana mākou i ka hoʻāʻo non-magnetic ma nā kaula uwea kila kila o nā anawaena like ʻole a me nā mea e hōʻoia ai i ka hoʻokō ʻana i nā kūlana haʻahaʻa-magnetic permeability i koi ʻia i nā noi koʻikoʻi e like me nā lumi MRI, hoʻohana pūʻali koa, a me nā mea kani pololei.

Hōʻike kēia hōʻike wikiō i kā mākou kaʻina hana hoʻāʻo magnetic, e hōʻoia ana i kā mākou kaula - i hana ʻia mai nā māka e like me 316L a me 304 stainless steel - mālama i nā waiwai non-magnetic ʻoiai ma hope o ka hana ʻana a me ka hana ʻana.

Hiki i ke kila kila ke lilo i mea mākēneki i ka manawa?

ʻAe.Hana anu(kūlou, hana, mīkini) hiki ke hoʻololi i ka microstructure o austenitic stainless steel a hoʻolaunawaiwai ferromagnetic. ʻAʻole kēia manaʻo ua hoʻololi ke ʻano o ka mea—ʻo ia hoʻi, ua liʻiliʻi iki ka ʻili.

Ka hopena

No laila,he kila kuhiliʻole ka magnetic?ʻO ka pane:ʻO kekahi, ʻaʻole kekahi.Pili ia i ka papa a me ka lapaau.

• Austenitic (304, 316): Non-magnetic ma ke ano annealed, manekini iki ma hope o ka hana anu.

• Feritic (430)aMartensitic (410, 420): Magnetic.

Ke koho ʻana i kahi kila kila no kāu noi, e noʻonoʻoʻo kona pale ʻana i ka corrosion a me nā waiwai magnetic. Inā koʻikoʻi ka non-magnetism, e hōʻoia me kāu mea hoʻolako a hoʻāʻo pololei i ka mea.
