Muminda ipi ndiyo nzira yekurebesa kwe yakakwira frequency induction kudziya michina kunyanya kushandiswa?

Chekutanga, kuti kuderedze kuomarara workpiece simbi uye kubereka simbi pashure forging, workpiece inopisa kusvika pamusoro 20-40 madhigirii Celsius, uye ipapo zvishoma nezvishoma kutonhora, kuti lamellar cementite mu pearlite anova spherical panguva kutonhora muitiro. , kuderedza kuoma kwesimbi, chiitiko ichi ndeche spheroidizing annealing.

Chechipiri, kuitira kuti zvigadziro zviri mu alloy casting zvigovane zvakaenzana, tinogona kupisa workpiece kune imwe tembiricha, asi pane fungidziro yekuti haigone kunyungudutswa, chengetedza ichidziya kwenguva yenguva kubvumira zvikamu zvemukati zve. workpiece kuti igovane zvakaenzana uye wozotonhorera pasi. Kuti iite kuti iwane mamwe makemikari zvimiro zvekuvandudza mashandiro ayo, iyi nzira yekudziya ndeye diffusion annealing.

Chechitatu, simbi dzakakandwa uye zvikamu zvakasungwa kazhinji zvine kushushikana kwemukati. Tinogona kushandisa yakakwira-frequency induction yekudziisa yekudziisa, uye tembiricha inofanirwa kunge iri pasi pe100-200 ° C, uye tozoirega ichitonhoresa. Kunyaradza kushushikana.

Chechina, kugadzira simbi yakakandwa ine simenti mupurasitiki yakakandwa simbi, isu tinogona zvakare kushandisa induction yekudziya midziyo yekudziya zvishoma nezvishoma kusvika kune tembiricha inosvika 1000 madhigirii, uye ita kuti itonhorere zvishoma nezvishoma, kuitira kuti simende yemukati iparadzwe. muflocculent graphite, uye iyi nzira yekudziya ndeye graphite annealing.

Chechishanu, semuenzaniso, mukuita kwekutonhora kukunguruka kana kutonhora kudhirowa, iyo yakaoma chiitiko inowanikwa mumatare esimbi uye mashizha. Kuti tibvise chiitiko ichi chakaoma, tinofanira kukurumidza kudzora tembiricha yeworkpiece kana ichidziya kusvika 50-150 degrees Celsius. Kuomesa workpiece kupfavisa simbi, iyi kudziyisa nzira iri recrystallization annealing.
