Chii ichocho yakakwira frequency kudzima?

Kudzima imhando yekurapa kwekupisa, kusanganisira kudzima zvakazara, kudzima pulse uye isothermal quenching.

Kazhinji, kudzima kunoita kuti workpiece ive neimwe microstructure kuti ive nechokwadi chekuti chimwe chikamu chinosangana nezvinodiwa zvemuchina mushure mekupisa. Inogona kuvandudza kuoma uye simba; kuwedzera kupfeka kusagadzikana.

Pulse quenching ndeyekupisa iyo workpiece munguva pfupi kwazvo (yakadai se1/1000 sekondi) nerubatsiro rwesimba repamusoro repurusi, uye nekuitonhodza nekukurumidza, iyo inogona kuwana yakanyanya kunaka zviyo uye kuoma kwakanyanya, pasina deformation, hapana oxide firimu, Kupfeka-inodzivirira uye inodzivirira kuora. Hapana kushatirwa kunodiwa mushure mekudzima.

Austempering ndiko kupisa workpiece kusvika quenching tembiricha, uye wozoiisa inodziya munyu kugeza kuti anokonzera imwe chimiro kushandura kwenguva yenguva kuwana bainite uye zvimwe zvimiro, kuti ane yakakwirira simba uye kuoma. Iyo yekudzima kushushikana idiki, iyo inogona kudzivirira denaturation uye kuputika. Inokodzera zvikamu zvitete uye zvakakura.
