Fast spheroidizing annealing tsari don shigar da dumama makera

The shigowa dumama tanderu hanzarin zubar da jini na hanzari shine tsarin haɗaɗɗen spheroidizing wanda aka kammala ta hanyar shigar da wutar makera austenitizing da matakin shirye -shiryen spheroidizing, kuma matakin spheroidizing an kammala shi da dumama ta gargajiya. Bada cikakkiyar wasa ga halayen hanyoyin dumama guda biyu kuma ku haɗu don samar da sabon tsarin saurin ɓarna.

Yin amfani da halayen hauhawar saurin zazzagewar murhun shigar da wutar lantarki don austenitization, ana samun kyawawan lu’ulu’u na austenite na farko, waɗanda ke haifar da abubuwan da ake buƙata don sanyaya mai zuwa don samun hatsi mai kyau. Dangane da yanayi daban -daban na sanyaya yanayi, ana samun tsarin farko na spheroidizing. Dabbobi daban -daban na shirye -shiryen spheroidizing suna warwatse kuma anneled su ta amfani da hanyoyin dumama na gargajiya don samun kyallen kyallen takarda.

Dangane da yanayin sanyi daban -daban na austenitizing, tsarin shirye -shiryen spheroidizing ya kasu kashi uku masu zuwa:

(1) Tsarin shiri na spheroidized wanda iska ta sanyaya (daidaitawa) shine pearlite.

(2) Tsarin shirye -shiryen spheroidization wanda aka sanya ta hanyar sanyaya ruwa (kashewa) shine martensite + riƙe austenite.

(3) Tsarin shiri na spheroidized wanda aka sanya ta sanyaya ruwa (maimaita dumama da kashe sama da 400 ° C) sorbite ne.
