Kurumidza spheroidizing annealing maitiro e induction kudziya choto

The induction kupisa chira inokurumidza spheroidizing annealing maitiro ndeye yakasanganiswa spheroidizing maitiro ayo anozadzikiswa neiyo induction yekudziya choto austenitizing uye spheroidizing gadziriro yekugadzirira, uye iyo spheroidizing nhanho inopedzwa neyakajairwa kudziya. Ipa kutamba kuzere kumaficha enzira mbiri dzekupisa uye sangana kuti ugadzire nyowani yekukurumidza spheroidizing yekuwedzera chiitwa.

Kushandisa hunhu hweye inokurumidza tembiricha inokwira yeiyo induction yekupisa choto yeaustenitization, iyo yakanaka austenite makristasi ekutanga anowanikwa, izvo zvinogadzira izvo zvinotarisirwa zveinotevera kutonhora kuti uwane tsanga dzakanaka. Zvinoenderana neakasiyana mamiriro ekutonhora ekusimbisa, akasiyana maspheroidizing ekutanga masisitimu anowanikwa. Misiyano yakasiyana yekugadzirisa spheroidizing inogadzirwa uye yakasimbiswa uchishandisa echinyakare kudziya nzira kuti pakupedzisira uwane spheroidizing matishu.

Zvinoenderana neakasiyana mamiriro ekutonhora ekusimbisa, iyo spheroidizing gadziriro yekugadzirira yakakamurwa kuita matatu matatu anotevera:

(1) Iyo spheroidized yekugadzirira chimiro chakaumbwa nemhepo kutonhora (yakajairika) iri pearlite.

(2) Iyo spheroidization yekugadzirira chimiro chakaumbwa nemvura kutonhora (kudzima) ndeye martensite + yakachengetedzwa austenite.

(3) Iyo spheroidized yekugadzirira chimiro chakaumbwa nemvura kutonhora (inodzokororwa kudziyisa uye kudzima pamusoro pe400 ° C) iri sorbite.
