Kodi Chitsulo Chopanda Magnetic N'chiyani?

Anthu akamaganiza za chitsulo, nthawi zambiri amaganiza za chitsulo cholimba komanso champhamvu. Komabe, si zitsulo zonse zomwe zimakhala ndi mphamvu ya maginito. Ndipotu, mitundu ina ya chitsulo—makamaka mitundu yeniyeni ya chitsulo chosapanga dzimbiri—imadziwika kuti si ya maginito kapena imangogwiritsa ntchito mphamvu ya maginito pang'ono. Kumvetsetsa zomwe zimapangitsa zitsulo zina kukhala zopanda mphamvu ya maginito n'kofunika kwambiri kwa mainjiniya, opanga mapulani, ndi opanga omwe amagwira ntchito m'mafakitale monga kukonza chakudya, zida zamankhwala, ntchito zapamadzi, ndi zamagetsi.

Munkhaniyi, tifufuza mitundu ya chitsulo chomwe sichili ndi maginito, chifukwa chake chimachita motero, komanso komwe chimagwiritsidwa ntchito kwambiri. Monga wogulitsa wodalirika wa zitsulo zosapanga dzimbiri zapamwamba,SAKYSTEELimapereka ukatswiri waukadaulo wozama komanso zipangizo zapamwamba kwambiri zofunikira zonse zachitsulo chosakhala cha maginito.

1. Kodi “Chitsulo Chopanda Magneti” Chimatanthauza Chiyani?

Chitsulo chopanda maginitoamatanthauza ma alloys omwe sasonyeza kukopa kwamphamvu kwa maginito. M'mawu asayansi, amagawidwa m'magulu aausteniticzitsulo chifukwa cha kapangidwe kake ka kristalo, komwe kamadziwika kutikiyubiki yoyang'ana nkhope (FCC)Kapangidwe kameneka sikalola kuti madera a maginito azigwirizana, zomwe zimapangitsa kuti chitsulocho chisakhale cha maginito kwenikweni.

Komabe, ndikofunikira kuzindikira kuti zitsulo zina zimatha kukhala ndi mphamvu ya maginito pang'ono pambuyo pogwira ntchito yozizira kapena kuwotcherera, koma zimakhalabe ndi mphamvu ya maginito yofooka kwambiri poyerekeza ndi zitsulo za ferritic kapena martensitic.

2. Sayansi Yokhudza Magnetism mu Chitsulo

Mphamvu ya maginito mu chitsulo imadalira kwambiri kapangidwe kake kakang'ono. Pali mitundu itatu ikuluikulu ya kapangidwe kake kakang'ono ka chitsulo chosapanga dzimbiri:

• Austenitic (Yopanda Magneti)– Kapangidwe ka cubic koyang'ana pakati pa nkhope; kali ndi nickel ndi chromium yambiri; kopanda maginito ngati kakulumikizidwa.

• Ferritic (Maginito)– Kapangidwe ka cubic kokhazikika m'thupi; kali ndi chromium koma nickel yochepa kapena yopanda; kali ndi mphamvu ya maginito.

• Martensitic (Maginito)– Mpweya wambiri ndi chromium; mphamvu ya maginito komanso yolimba chifukwa cha kutentha.

Zitsulo zosapanga dzimbiri za Austenitic zimakhala ndi mphamvu zopanda mphamvu chifukwa cha nickel, yomwe imalimbitsa kapangidwe ka FCC ndikuletsa mapangidwe a maginito a ferrite kapena martensite.

3. Zitsulo Zosagwiritsa Ntchito Magneti

A. Zitsulo Zosapanga Dzimbiri za Austenitic

Izi ndi zitsulo zopanda maginito zomwe zimagwiritsidwa ntchito kwambiri. Magiredi ofunikira ndi awa:

• Chitsulo Chosapanga Dzira cha 304 (UNS S30400)
  Chodziwika kuti ndi chitsulo chosapanga dzimbiri chodziwika bwino, 304 ili ndi 18% chromium ndi 8% nickel. Sichimakhala ndi maginito ngati chimagwiritsidwa ntchito mopanda mphamvu koma chimatha kukhala ndi maginito pang'ono pambuyo pogwira ntchito yozizira kwambiri.

• 316 Stainless Steel (UNS S31600)
  Ili ndi molybdenum yothandiza kuti isamavutike ndi dzimbiri, makamaka m'malo okhala ndi zinthu za m'nyanja ndi mankhwala. Imakonda kugwiritsidwa ntchito m'malo omwe kukana dzimbiri komanso momwe imagwirira ntchito popanda mphamvu ya maginito kumafunikira.

• Zitsulo Zosapanga Dzimbiri 310 ndi 321
  Magiredi awa nawonso si amagetsi ndipo amapangidwira ntchito zoteteza kutentha kwambiri kapena kuzizira.

• Chitsulo Chosapanga Dzira cha 904L (UNS N08904)
  Mtundu wa super austenitic wokhala ndi nickel yambiri (24–26%) ndi molybdenum (4–5%), zomwe zimapangitsa kuti usakhale ndi maginito ngakhale utapangidwa.

4. N’chifukwa Chiyani Muyenera Kugwiritsa Ntchito Chitsulo Chopanda Magineti?

Zitsulo zopanda maginito zimathandiza kwambiri m'mafakitale komwe kusokoneza maginito, dzimbiri, ndi ukhondo ndizofunikira kwambiri. Ubwino wake ndi monga:

• Kutha kwa Magnetic Kotsika:Zimaletsa kusokonezeka kwa maginito mu zida zamagetsi kapena zoyezera zomwe zimakhala zosavuta.

• Kukana Kwambiri Kudzimbiri:Zabwino kwambiri pa ntchito za m'madzi, mankhwala, komanso zachipatala.

• Kuyeretsa:Malo osalala komanso opanda mabowo amaletsa mabakiteriya kusonkhana—abwino kwambiri pamakampani opanga chakudya ndi mankhwala.

• Kulimba ndi Mphamvu:Imasunga kulimba kwambiri ngakhale kutentha kwambiri.

5. Kugwiritsa Ntchito Zitsulo Zosapanga Magnetic

Chifukwa cha kuphatikiza kwawo kwapadera kwa katundu, zitsulo zopanda maginito zimagwiritsidwa ntchito mu:

A. Zipangizo Zachipatala ndi Zachipatala

Zitsulo zosapanga dzimbiri zopanda maginito zimagwiritsidwa ntchito pa zipangizo zopangira opaleshoni, zida zojambulira za MRI, ndi mipando yachipatala chifukwa sizimasokoneza mphamvu ya maginito.

B. Kapangidwe ka Zam'madzi ndi Zam'mphepete mwa Nyanja

Zitsulo zosapanga dzimbiri za 316 ndi 904L zimagwiritsidwa ntchito kwambiri pazida zombo, ma propeller shafts, ndi nsanja za m'mphepete mwa nyanja, zomwe zimateteza dzimbiri la madzi a m'nyanja komanso mphamvu zochepa zamaginito.

C. Makampani Okonza Zakudya ndi Zakumwa

Magiredi a Austenitic monga 304 ndi 316 amatsimikizira ukhondo, ukhondo, komanso kukana ma acid ndi mchere zomwe zimapezeka mu kukonza chakudya.

D. Mapulogalamu Oyendetsera Ndege ndi Chitetezo

Katundu wosakhala wa maginito ndi wofunikira kwambiri m'nyumba zosungiramo zida ndi zida za ndege, komwe kusokoneza maginito kungakhudze magwiridwe antchito.

E. Machitidwe a Zamagetsi ndi a Cryogenic

Zitsulo za Austenitic zimasunga bata pamalo ozizira kwambiri ndipo sizimasokoneza masensa a maginito, zomwe zimapangitsa kuti zikhale zabwino kwambiri pa matanki osungiramo zinthu zobisika komanso zipangizo zolondola.

6. Zinthu Zomwe Zingakhudze Magnetism mu Chitsulo Chosapanga Dzimbiri

Ngakhale zitsulo zopanda maginito zimatha kukhala ndi maginito pang'ono chifukwa cha:

• Kugwira Ntchito Mozizira (Kupanga, Kupinda, kapena Kuzungulira):Kupsinjika kwa makina kungayambitse kusintha pang'ono kukhala martensite, zomwe zimapangitsa kuti maginito aziwonjezeka pang'ono.

• Kuwotcherera:Malo omwe amakhudzidwa ndi kutentha amatha kuyambitsa ferrite, zomwe zimapangitsa kuti maginito a m'deralo ayambe.

• Kusiyana kwa kapangidwe kake:Kuchepa kwa nickel kungachepetse kukhazikika kwa austenitic, zomwe zimawonjezera chiopsezo cha kuyankha kwa maginito.

Kuti asunge zinthu zopanda mphamvu ya maginito, opanga ayenera kuyang'anira mosamala kapangidwe ka alloy ndi momwe amagwirira ntchito.

7. Momwe Mungayesere Ngati Chitsulo Sichili ndi Magnetic

Njira yosavuta yoyesera ndi kugwiritsa ntchito maginito ang'onoang'ono. Ikani pafupi ndi pamwamba pa chitsulo:

• Ngati palipalibe chokopa, siili ndi mphamvu ya maginito (austenitic).

• Ngatikumamatira pang'ono, ikhoza kukhala ndi magawo ena a ferritic kapena martensitic chifukwa cha ntchito yozizira.

• Ngatikumamatira mwamphamvu, ndi ya maginito (ferritic kapena martensitic).

Ma laboratories aluso amatha kuyeza kulola kwa maginito molondola kwambiri pogwiritsa ntchito zida zapadera.

8. Kuyerekeza Pakati pa Zitsulo za Magnetic ndi Nonmagnetic
