Pane nzira gumi dzinowanzo shandiswa kudzima mukupisa kurapwa, kusanganisira imwe svikiro (mvura, mafuta, mhepo) kudzima; huviri hwepakati quenching; martensite graded quenching; martensite graded quenching nzira pazasi Ms point; bainite isothermal Quenching nzira; musanganiswa quenching nzira; precooling isothermal quenching nzira; kunonoka kutonhora kudzima nzira; kudzima nzira yekuzvidzora; kupfapfaidza quenching nzira, nezvimwewo.
1. Single medium (mvura, mafuta, mhepo) inodzima
Single-medium (mvura, mafuta, mhepo) quenching: The workpiece yave kudziyisa kusvika quenching tembiricha inodzimwa kupinda quenching svikiro kuti itonhodze zvachose. Iyi ndiyo nzira yakapusa yekudzima uye inowanzoshandiswa kune kabhoni simbi uye alloy simbi yekushanda ine maumbirwo akareruka. Iyo yekudzima svikiro inosarudzwa zvinoenderana neiyo kupisa kupisa coefficient, kuoma, ukuru, chimiro, nezvimwe zvechikamu.
2. Double medium quenching
Dual-medium quenching: Iyo workpiece inopisa kusvika pakudzima tembiricha inotanga kutonhodzwa kuti ivhare kuMs point mune yekudzima svikiro ine simba rekutonhora kutonhora, uye yozoendeswa kune inononoka-inotonhorera yekudzima svikiro kuti inotonhorera kukamuri tembiricha kuti isvike kwakasiyana quenching kutonhora. tembiricha siyana uye vane Zvine mwero yakanaka quenching kutonhora mwero. Iyi nzira inowanzoshandiswa kune zvikamu zvine maumbirwo akaoma kana makuru ekushanda akagadzirwa nepamusoro-kabhoni simbi uye alloy simbi. Carbon tool steels zvakare inowanzoshandiswa. Inowanzo shandiswa kutonhora midhiya inosanganisira mvura-mafuta, mvura-nitrate, mvura-mhepo, uye mafuta-mhepo. Kazhinji, mvura inoshandiswa senzira yekukurumidza kutonhora yekudzima, uye oiri kana mweya inoshandiswa senzira inononoka kutonhora yekudzima. Mhepo haiwanzo shandiswa.
3. Martensite graded quenching
Martensitic graded quenching: iyo simbi inosimbiswa, uye yobva yanyudzwa mumvura yemvura (munyu yekugezera kana alkali bhati) ine tembiricha yakakwira zvishoma kana kuderera zvishoma pane yepamusoro Martensite point yesimbi, uye inochengetwa kwenguva yakakodzera kusvika mukati uye kunze kwekunze kwezvikamu zvesimbi Mushure mokunge mitsara yasvika pakupisa kwepakati, inotorwa kunze kwemhepo inotonhorera, uye iyo supercooled austenite inoshandurwa zvishoma nezvishoma kuva martensite panguva yekudzima. Iyo inowanzo shandiswa kune madiki workpieces ane yakaoma maumbirwo uye yakasimba deformation zvinodiwa. Iyi nzira inowanzoshandiswa kudzima simbi yakakwirira-yepamusoro-soro uye maturusi esimbi uye molds.
4. Martensite graded quenching nzira pazasi Ms point
Martensite graded quenching method pazasi Ms point: Kana tembiricha yekugezesa yakadzikira pane Ms weworkpiece simbi uye yakakwira kupfuura Mf, iyo workpiece inotonhora nekukurumidza mubhavhu, uye mibairo yakafanana sekudzima kwegiredhi inogona kuwanikwa kana saizi yakakura. Kazhinji inoshandiswa kune yakakura simbi workpieces ine yakaderera kuoma.
5. Bainite isothermal quenching nzira
Bainite isothermal quenching nzira: Iyo workpiece inodzimwa mubhavhu ine yakaderera bainite tembiricha yesimbi uye isothermal, kuitira kuti yakaderera bainite shanduko iitike, uye kazhinji inochengetwa mubhavhu kwemaminetsi makumi matatu kusvika makumi matanhatu. The bainite austempering process ine matanho makuru matatu: ① austenitizing kurapwa; ② post-austenitizing kutonhora kurapwa; ③ bainite isothermal kurapwa; inowanzoshandiswa mu alloy simbi, yakakwira kabhoni simbi diki-saizi zvikamu uye ductile iron castings.
6. Compound quenching nzira
Compound quenching nzira: tanga wadzima iyo workpiece kusvika pazasi Ms kuti uwane martensite ine vhoriyamu chikamu che10% kusvika 30%, uyezve isotherm munzvimbo yepasi bainite kuti uwane martensite uye bainite zvimiro zveakakura-chikamu-chikamu workpieces. Inowanzoshandiswa Alloy tool simbi workpieces.
7. Precooling uye isothermal quenching nzira
Pre-kutonhora isothermal quenching nzira: inonziwo kudziyisa isothermal quenching, zvikamu zvinotanga kutonhodzwa mubhavhu ine tembiricha yakaderera (yakakura kupfuura Ms), uye yozoendeswa kune yekugezera ine tembiricha yepamusoro kuita kuti austenite iite isothermal shanduko. Inokodzera zvikamu zvesimbi zvine kuomeswa kwakashata kana maworkpieces makuru anofanirwa kuve akaomeswa.
8. Kunonoka kutonhora uye kudzima nzira
Kunonoka kutonhora kudzima nzira: Zvikamu zvinotanga kutonhorera mumhepo, mvura inopisa, kana munyu yekugezera kune tembiricha yakakwira zvishoma kupfuura Ar3 kana Ar1, uye ipapo kudzima-yepakati kunoitwa. Inowanzo shandiswa kune zvikamu zvine maumbirwo akaomarara uye zvakakura zvakasiyana-siyana makobvu muzvikamu zvakasiyana uye zvinoda diki deformation.
9. Kudzima uye kuzvidzora nzira
Kudzima uye kuzvidzora nzira: Iyo yese workpiece inofanirwa kugadziriswa inopisa, asi panguva yekudzima, chete chikamu chinoda kuomeswa (kazhinji chikamu chinoshanda) chinonyudzwa mumvura yekudzima uye kutonhora. Kana ruvara rwemoto rwechikamu chisina kunyudzwa chinonyangarika, pakarepo chibudise kunze mumhepo. Medium kutonhora quenching process. Nzira yekudzima uye yekuzvidzora inoshandisa kupisa kubva pakati pepakati iyo isati yanyatsotonhodzwa kuti iende kune pamusoro kuti igopisa pamusoro. Zvishandiso zvinowanzo shandiswa kushingirira kuita senge chisel, zvibhakera, sando, nezvimwe.
10. Spray quenching nzira
Spray quenching method: Nzira yekudzima iyo mvura inopfapfaidzwa pane yebasa. Mvura inoyerera inogona kuva yakakura kana diki, zvichienderana nekudzika kunodiwa kwekudzima. Iyo yekupfapfaidza quenching nzira haigadziri firimu remhepo pamusoro peiyo workpiece, nekudaro kuve nechokwadi chakadzika chakaomeswa rukoko pane kudzima kwemvura. Inonyanya kushandiswa kudzima pamusoro penzvimbo.
