Njira yofulumizitsa yolowererapo yotentha ndi ng’anjo

The magetsi oyatsira moto njira yothamangitsira spheroidizing ndikumanga kophatikizana komwe kumamalizidwa ndikuwotcha kwamoto ndi gawo lokonzekera bwino, ndipo gawo lokhathamiritsa limamalizidwa ndi kutentha kwanyengo. Chitani masewera athunthu pamakhalidwe a njira ziwiri zotenthetsera ndikuphatikizani kuti mupange njira yatsopano yolimbikitsira.

Pogwiritsira ntchito mawonekedwe a kutentha kwakanthawi kofulumira kwa ng’anjo yotenthetsera moto ya austenitization, timibulu tomwe timakhala tomwe timayambira kale timapezeka, zomwe zimapanga zofunikira pakuziziritsa komwe kumakhalapo kuti mupeze mbewu zabwino. Malinga ndi kuziziritsa kosiyanasiyana kwa kulimbitsa thupi, zimapezeka mosiyanasiyana zoyambira. Mitundu yosiyanasiyana yokonzekereratu imapangidwanso ndikukongoletsedwa pogwiritsa ntchito njira zotenthetsera kuti pamapeto pake muzipeza ziwalo zopatsa mphamvu.

Malinga ndi kuziziritsa kosiyanasiyana kwa kulimbitsa thupi, kapangidwe kake kowoneka bwino kamagawidwa m’mitundu itatu iyi:

(1) Spheroidized kukonzekera dongosolo opangidwa ndi kuzirala kwa mpweya (normalizing) ndi pearlite.

(2) Kapangidwe ka spheroidization kamene kamapangidwa ndi kuzirala kwamadzi (kuzimitsa) ndi martensite + yosungabe austenite.

(3) Kapangidwe kake kokongola kamene kamapangidwa ndi kuzirala kwamadzi (kutenthetsa mobwerezabwereza ndi kuzimitsa pamwamba pa 400 ° C) ndi sorbite.
