  • Idan aka gano magnetization na gida (saboda damuwa ko gurɓatar ƙarfe), yi demagnetization (misali, annealing ko degaussing na musamman).

3. Rage ƙarfin maganadisu (Idan Ana Bukata)

• Ƙararrawa:
  • A dumama a cikin tanderun da ke da yanayi mai sarrafawa zuwa zafin da kayan ke fitarwa (misali, 600–800°C don ƙarfen Monel) don kawar da damuwa da maganadisu da suka rage.
  • A bi ƙa'idodin masana'anta sosai don guje wa zafi fiye da kima, wanda zai iya haifar da tsatsa tsakanin granular ko lalacewar injiniya.
• Degaussing na Gida:
  • Yi amfani da kayan aikin cire wutar lantarki don mayar da hankali kan wuraren da aka yi maganadisu da kuma dawo da halayen da ba na maganadisu ba.

4. Rigakafin Tsatsa da Man Shafawa

• Rufin Hana Tsatsa:
  • Gyara ƙananan lalacewar saman ta amfani da fenti mai taɓawa ko shafa mai na epoxy don hana yaɗuwar tsatsa.
• Kariyar Zare:
  • A shafa man shafawa marasa ƙarfe (misali, man shafawa mai tushen molybdenum disulfide) a kan zare don hana lalacewa da tsatsa.
  • Sanya kayan kariya na zare (misali, murfi na filastik) yayin ajiya ko jigilar kaya.

5. Gudanar da Ajiya

• Bukatun Muhalli:
  • A adana a cikin busasshiyar wuri mai iska, tare da ɗanɗano ƙasa da kashi 60% da kuma yanayin zafi mai kyau.
  • A kiyaye daga maɓuɓɓugan maganadisu masu ƙarfi (misali, injina, na'urorin canza wutar lantarki).
• Matsayi:
  • Sanya a kwance a kan racks ɗin da aka keɓe don guje wa lanƙwasawa; kada a taɓa tara su a tsaye ko a tara su kai tsaye.
  • Duba yanayin ajiya a kowace kwata don ganin tsatsa ko nakasa.

6. Kare Sufuri

• Kariya da Gyaran Jiki:
  • Yi amfani da kayan aiki na musamman tare da kushin roba ko tubalan katako don hana faruwar abubuwa yayin jigilar kaya.
• Kariyar Magnetic:
  • An yi garkuwa da abin rufe fuska da kayan hana maganadisu idan ana jigilar su kusa da tushen maganadisu.

7. Gwajin Ƙwararru na Lokaci-lokaci

• Gwaji na Kullum:
  • Gudanar da gwaje-gwajen dakin gwaje-gwaje na wasu kamfanoni biyu a shekara/shekara, gami da:
    • Gwajin Inganci (bisa ga ASTM A342).
    • Gwajin Ultrasonic (UT) ko gwajin rediyo (RT) don gano lahani na ciki.
    • Binciken abubuwan da aka haɗa (misali, spectrometry) don tabbatar da ingancin da ba na maganadisu ba.
• Takardu:
  • Kula da bayanan sakamakon gwaji da ayyukan kulawa don bin diddigin zagayowar rayuwa.

8. Horar da Mai Aiki

• Horar da ma'aikata akai-akai akan:
  • Haramta kayan aikin ƙarfe yana tasiri akanNMDCs.
  • Gujewa aiki/ajiyewa kusa da ƙarfin filayen maganadisu.
  • Amfani da makullan karfin juyi don matse zaren bisa ga takamaiman ka'idoji.

Muhimman Kariya

• Guji walda: Ba a iya yin walda a NMDCs gabaɗaya; dole ne masana'antun da aka tabbatar su yi gyare-gyare.
• Daidaita Kayan Aiki: Tabbatar da cewa sinadaran tsaftacewa, man shafawa, da sauransu, sun dace da kayan abin wuya (misali, Monel alloys suna da saurin kamuwa da ammonia; a guji abubuwan da ke ɗauke da ammonia).

Kulawa ta tsari yana rage yawan aikiNMDCYawan kurakurai, tabbatar da daidaiton haƙa ramin da aka yi niyya da kuma amincin aiki. Sauya ko mayar da abin wuya da suka lalace ko suka yi maganadisu ga masana'anta nan take.

PS:

LANDRILLcan yana samar da cikakken nau'ikan abin wuya masu santsi da karkace a cikin NMDC tare da P530, P550, P650 da kayan da suka yi daidai. Tuntuɓe mu don ƙarin bayani.
