2. Kungani Ukulunywa Kungadingeki Ensimbini Engagqwali?

Nakuba amandla kazibuthe engathinti ukumelana nokugqwala noma amandla omshini, kwezinye izindawo angabangela izinkinga ezinkulu.

Nazi izibonelo ezimbalwa zokuthi kuphii-magnetism kumele isuswe:

• Imboni yezokwelapha:Amathuluzi okuhlinza kanye nemishini ehambisana ne-MRI kumele ingabi namandla kagesi nhlobo.

• Izinto zikagesi:Ukuphazamiseka kwamagnetic kungaphazamisa amasignali futhi kuthinte izinzwa.

• Izindiza kanye nokuzivikela:Izinto ezisebenzisa ugesi zingaphazamisa izinhlelo zokuzulazula nezokuthola.

• Amalabhorethri esayensi:Imishini kumele ingathathi hlangothi kumagnetic ukuqinisekisa ukulinganiswa okunembile.

• Ubunjiniyela bezolwandle:Uzibuthe lungadonsa izinhlayiya zensimbi noma luthonye amakhampasi nezinsimbi.

Ngenxa yalezi zizathu, abakhiqizi bavame ukwenzaukususwa komagnethi (ukususwa komagnethi)ngemva kokulungisa, ukushisela, noma ukwelashwa ngokushisa.

3.1 Ukususwa Kwamagnethi Okushisa (Inqubo Yokuncibilikisa)

Indlela ephumelela kakhulu yokususa i-magnetism ku-insimbi engagqwali ye-austeniticsekuphelileukuhlanza isixazululo.

Indlela esebenza ngayo:
Ngesikhathi sokusebenza emakhazeni, ukucindezeleka kubangela ukwakheka kwe-martensite—isigaba sikamazibuthe. Ukushisa izinto kuze kufike emazingeni okushisa aphezulu (ngokuvamile1050°C kuya ku-1100°C) ivumela isakhiwo sangaphakathi sekristalu ukuthi sibuyele ngokuphelele kui-austenite, ibuyisela isimo sayo esingesona esikazibuthe.

Izinyathelo zenqubo:

1. Shisa insimbi engagqwali ngokulinganayo ku-1050–1100°C (1920–2010°F).

2. Bamba ekushiseni imizuzu eyi-10-30 kuye ngokuthi ubukhulu buyini.

3. Kuphola ngokushesha (ukucima amanzi noma umoya ophoqelekile) ukuze kugwenywe imvula yama-carbide.

Inothi elibalulekile:

• Le nqubo ifanelekilekuphela ngamamaki e-austeniticnjenge-304, 316, 310S, kanye ne-321.

• Izinsimbi ze-Ferritic neze-martensitic azikwazi ukuba yi-non-magnetic ngokusebenzisa i-annealing ngoba izakhiwo zazo zekristalu zinamandla kagesi ngokwemvelo.

Isibonelo:
Ibha yensimbi engagqwali engu-304 eba magnetic ngemva komshini ingashiswa ku-1080°C kulandelwe ukupholisa okusheshayo. Lokhu kwelashwa kubuyisela isigaba sayo esiphelele se-austenitic esingeyona i-magnetic.

4. Isinyathelo Ngesinyathelo: Inqubo Yokususa Ugesi Kuma-Electromagnetic

Nansi indlela izikhungo zezimboni ezivame ngayo ukususa amandla kazibuthe ezingxenyeni zensimbi engagqwali kusetshenziswa i-AC demagnetization:

1. Linganisa amandla okudonsa okuqalausebenzisa i-gaussmeter (isisekelo sokurekhoda).

2. Khetha i-demagnetizer efanele(Ikhoyili ye-AC noma iyunithi ephathekayo).

3. Sebenzisa insimu yamagnetic eshintshanayokuya engxenyeni ngenkathi kunciphisa kancane kancane ubukhulu bamanje.

4. Khipha kancane noma ujikeleze ingxenyeukuze kuvezwe ngokulinganayo zonke izindawo ensimini ebolayo.

5. Hlola kabusha i-magnetism—umgomo ungaphansi kwensimu eseleyo ye-Gauss engu-2.

6. Phindauma kudingeka ngezimo ezinkulu noma eziyinkimbinkimbi.

Le nqubo isetshenziswa kabanziamaphampu, amavalvu, imiphini, izikhonkwane, amathuluzi okunemba, kanye nezingxenye zokushintshanisa ukushisalapho ukwelashwa kokushisa kungenzeki khona.
