Chidule chachidule cha sintering process ya iron-based MIM magawo

Chikoka cha sintering ndondomeko magawo pa ntchito ya chitsulo ofotokoza mbali Sintering ndondomeko magawo: sintering kutentha, sintering nthawi, kutentha ndi kuzirala liwiro, sintering mpweya, etc.

1. Sintering kutentha

Kusankhidwa kwa kutentha kwa sintering kwa zinthu zopangidwa ndi chitsulo makamaka kumatengera zomwe zimapangidwa (carbon content, alloy elements), zofunikira pakugwira ntchito (makina) ndi ntchito (magawo omanga, anti-friction parts), etc.

2. Sintering nthawi

Kusankhidwa kwa sintering nthawi ya zinthu zopangidwa ndi chitsulo makamaka kumachokera pakupanga mankhwala (carbon content, alloy elements), kulemera kwa unit, kukula kwa geometric, makulidwe a khoma, kachulukidwe, njira yotsegula ng'anjo, ndi zina zotero;

Nthawi ya sintering ikugwirizana ndi kutentha kwa sintering;

Nthawi zambiri sintering ndi 1.5-3h.

Mu ng'anjo yosalekeza, kusunga nthawi:

t = L/l ▪n

t - Kugwira nthawi (mphindi)

L- kutalika kwa lamba wa sintered (cm)

l - Kutalika kwa ngalawa yoyaka kapena graphite board (cm)

n - nthawi yokankha bwato (min/boat)

3. Kutentha ndi kuzizira

The Kutentha mlingo amakhudza volatilization liwiro la lubricant, etc.;

Kuzizira kumakhudza mawonekedwe a microstructure ndi machitidwe a mankhwala.
