Kudzima inzira yakakosha musimbi yekupisa kurapwa, iyo inoshandura iyo yemuviri uye yemagetsi maitiro ezvigadzirwa kuburikidza nekukurumidza kutonhora. Munguva yekudzima, iyo workpiece inopinda nhanho dzakadai seyepamusoro-tembiricha kudziyisa, insulation, uye nekukurumidza kutonhora. Kana iyo workpiece inokurumidza kutonhora kubva pakupisa kwepamusoro, nekuda kwekudzikisira kwekusimba kwechikamu chekushandura, iyo microstructure yeworkpiece inoshanduka, ichigadzira zviyo zvitsva zvimiro uye kugovera kunetseka mukati.
Mushure mekudzima, iyo workpiece inowanzove mune yakakwira tembiricha mamiriro uye haisati yanyatsotonhorera kusvika kukamuri tembiricha. Panguva ino, nekuda kwekusiyana kukuru kwekushisa pakati pepamusoro pebasa rekushanda uye zvakatipoteredza, workpiece icharamba ichiendesa kupisa kubva kumusoro kusvika mukati. Iyi nzira yekupisa yekupisa inogona kutungamira kune emuno tembiricha gradients mukati meworkpiece, zvichireva kuti tembiricha munzvimbo dzakasiyana mukati meiyo workpiece haina kufanana.
Nekuda kwekunetseka kwakasara uye shanduko yezvimiro inogadzirwa panguva yekudzima, kusimba uye kuoma kweiyo workpiece kuchave kwakanyanya kuvandudzwa. Nekudaro, shanduko idzi dzinogonawo kuwedzera brittleness yeworkpiece uye zvinogona kukonzera kumwe kukanganisa kwemukati senge makatsemuka kana deformation. Naizvozvo, zvinodikanwa kuita tempering kurapwa pane workpiece kubvisa zvakasara kushushikana uye kuzadzisa inodiwa kuita.
Tempering inzira yekupisa iyo workpiece kune imwe tembiricha uye wozoitonhodza, nechinangwa chekuvandudza microstructure uye zvivakwa zvinogadzirwa mushure mekudzima. Tembiricha yekudziya kazhinji yakadzikira pane tembiricha yekudzima, uye tembiricha yakakodzera inogona kusarudzwa zvichienderana nehunhu uye zvinodiwa zvechinhu. Kazhinji, iyo yakakwira tembiricha yekudziya, inodzika kuomarara uye kusimba kweiyo workpiece, nepo kuoma uye plastiki inowedzera.
Zvisinei, kana workpiece haina kutonhodzwa kusvika kamuri tembiricha, kureva ichiri pakakwirira tembiricha, tempering kurapwa hazviitike. Izvi zvinodaro nekuti kudziya kunoda kudziyisa iyo workpiece kune imwe tembiricha uye kuibata kwenguva yakati kuti iwane mhedzisiro yaunoda. Kana iyo workpiece yatove pane yakanyanya tembiricha, iyo yekudziya uye yekumisikidza maitiro haizogoneke, izvo zvinozoita kuti kushatirwa kusasangana zvinotarisirwa.
Naizvozvo, usati waitisa kurapa kwekupisa, zvinodikanwa kuve nechokwadi kuti iyo workpiece yakanyoroveswa zvakakwana kune tembiricha yekamuri kana padyo nekamuri tembiricha. Nenzira iyi chete ndiyo inogona kurapa kunyorova kunoitwa kugadzirisa mashandiro eiyo workpiece uye kubvisa kuremara uye kushushikana kunogadzirwa panguva yekudzima.
Muchidimbu, kana iyo yakadzimwa workpiece isina kutonhodzwa kusvika kune tembiricha yekamuri, haizokwanisi kuitiswa kushatirwa. Kupisa kunoda kupisa iyo workpiece kune imwe tembiricha uye kuichengeta kwenguva yakati, uye kana workpiece yatove pane yakanyanya tembiricha, iyo tempering haigone kuitwa zvinobudirira. Naizvozvo, zvakakosha kuti uve nechokwadi chekuti workpiece yakanyatsotonhorera kusvika kukamuri tembiricha isati yapisa panguva yekupisa kurapwa kuti ive nechokwadi chekuti workpiece inogona kuzadzisa zvinodiwa kuita uye mhando.
