Nchifukwa chiyani mbale yathu yonyamulira imakhala ndi mphamvu yotha kunyamulira?

1. Kapangidwe ka mankhwala opangidwa pamwamba ndiye chinsinsi.

Zosakaniza zazikulu za mbale za Wodon ndi C(%) :3.0-5.0 ndi Cr(%):25-40.

Kuchuluka kwa mankhwala kumeneku kumabweretsa kuchuluka kwa tinthu tolimba ta Cr7C3 chrome carbide. Kuuma pang'ono (mpaka HV1800)mwa iziTinthu tating'onoting'ono tomwe timapangidwa pamwamba pake tidzatsimikizira kuti pamwamba pake sipawonongeka kwambiri.

 

 

 

 

 

 

 

 

 

 

Mayeso a Magwiridwe Antchito:

Zipangizo zoyesera: Gudumu la rabara la mchenga wa Quartzmakina oyesera kuphwanya.

Zofunikira: 1. Kusankha zitsanzo zofanana za zinthu zosiyanasiyana ndi opanga mbale zotayidwa, ndikuziyikapansi pa mikhalidwe yofanana yogwirira ntchito mu zida zathu zoyesera.

2.Mphindi 45 pa chitsanzo chilichonse

2. Kapangidwe kakang'ono ka chromium carbide

Kukana kwa mbale yopalira kumadalira kwambiri kuuma, mawonekedwe, kukula, kuchuluka ndi kufalikira kwa chromium.tinthu tolimba ta carbide.

 

Monga momwe mungawonere pachithunzichi, gawo la voliyumu ya carbide (Cr7C3) pa microstructure ili pamwamba pa 50%.

 

3. Mphamvu yolumikizirana pakati pa mbale yophimba ndi yoyambira.

Chophimba ndi mbale yoyambira zimalumikizana bwino kwambiri. Chophimbacho chidzalowa mu mbale yoyambira pafupifupi 0.8mm-1.8mm, kufikampaka 350Mpa mu mayeso athu.
