Izvo zvinodiwa kuitisa kupisa kurapwa mushureforgingnokuti chinangwa chayo ndechokubvisa kushushikana kwemukati mushure mekugadzira. Gadzirisa kuoma kwekugadzira, kunatsiridza kuita kwekucheka; Mbeu dzakaomarara mukugadzira nzira dzakanatswa uye dzakafanana kugadzirira iyo microstructure yezvikamu zvekupisa kupisa.

1. High tembiricha tembiricha: kuderedza kuoma, kuderedza kana kubvisa kushushikana kunogadzirwa kana normalizing kutonhora, kunatsiridza plasticity uye kuoma. Inokodzera simbi yealloy nehupamhi hwekuoma mushure me normalizing.

2. Kuzadza annealing: bvisa iyo yakakasharara uye isina kuenzana chimiro chinokonzerwa nekugadzira nzira, kunatsa zviyo, kubvisa yakasara kunetseka kwekugadzira, kuderedza kuoma, kuvandudza machinability, uye gadzirira sangano remangwana kupisa kwezvikamu. Kuzadza annealing kazhinji kwakakodzera kune hypoeutectoid simbi.

3. Isothermal annealing: kuwana yunifomu chimiro pane annealing yakakwana, zvinobudirira kubvisa forging stress, kuderedza kuoma. Mune zvakakosha mafogiji makuru, inogona zvakare kushandiswa kuparadzira hydrogen uye kudzivirira kugadzirwa kwemavara machena. Kana ichienzaniswa neyakakwana annealing, inogona kupfupisa iyo annealing nguva uye kugadzirisa kugadzirwa kwakanaka.

4. Normalizing: yakanaka pearlite inogona kuwanikwa kunatsiridza sangano; Vandudzaforgingssimba uye kuoma, kuderedza kushushikana kwemukati, kunatsiridza kucheka kwekuita; Ye eutectoid simbi. Mesh carbides inogona kubviswa.

5 spheroidization annealing: kuwana spherical cementite uye ferrite chimiro, kwete chete kuderedza kuomarara, uye mukucheka muitiro zviri nyore kuwana yakatsetseka processing pamusoro, muunotevera quenching hakusi nyore kubudisa deformation makatsemuka. Spheroidizing annealing inokodzera yakakwira kabhoni simbi uye yakakwira kabhoni alloy die simbi.
