Kune nzira gumi dzinowanzo shandiswa dzekudzima mukugadzirisa kupisa, dzinoti single medium (mvura, mafuta, mhepo) quenching; Double medium quenching; Grade quenching ye martensite; Grade quenching yemartensite pazasi Ms point; Bainite isothermal quenching nzira; Composite quenching nzira; Pre kutonhora isothermal quenching nzira; Kunonoka kutonhora kudzima nzira; Kudzima uye kuzvidzora nzira; Spray quenching nzira, nezvimwewo.

1、 Single medium (mvura, mafuta, mhepo) inodzima

Single medium (mvura, mafuta, mhepo) quenching: Kudzima midziyo yebasa yakatsvairwa kudzima tembiricha kuita svikiro rekudzima kuti zvinyatsotonhorerwa. Iyi ndiyo nzira yakapusa yekudzima, inowanzo shandiswa kabhoni simbi uye alloy simbi yekushanda ine maumbirwo akareruka. Iyo yekudzima svikiro ichasarudzwa maererano neyakagadzika kupisa kweyekupisa, kuoma, ukuru, chimiro, nezvimwe zvechikamu.

3、 Nhanho yekudzima martensite Danho rekudzima martensite: iyo simbi inogadziriswa, uye yobva yanyudzwa mumvura yemvura (munyu wekugezera kana alkali bhati) ine tembiricha yakakwira zvishoma kana kuderera pane yekumusoro martensite point yesimbi, uye inochengetwa kwenguva yakakodzera. . Kana zvidimbu zvemukati nekunze zvezvikamu zvesimbi zvinosvika pakupisa kwepakati, zvinotorwa kunze kwekutonhodzwa kwemhepo, uye iyo undercooled austenite inoshandurwa zvishoma nezvishoma kuva martensite. Kazhinji inoshandiswa kune zvidiki zvekushanda zvine maumbirwo akaomarara uye zvakaomesesa deformation zvinodiwa, iyi nzira inowanzo shandiswa kudzima simbi yepamusoro uye yakakwirira alloy simbi molds. 4、 Kudzimwa kwegiredhi yemartensite pazasi Ms point kwakagadziridzwa kudzimwa kwemartensite pazasi Ms point: kana tembiricha yekugezera yakadzikira kupfuura Ms wesimbi inoshandiswa pakushanda asi yakakwira kupfuura Mf, iyo workpiece inotonhora nekukurumidza mubhavhu, uye mhedzisiro yakafanana inogona kuramba ichiripo. kuwanikwa kana saizi yakakura. Inowanzo shandiswa kune yakakura-saizi yakaderera kuomarara simbi workpieces. 5、 Bainite isothermal quenching nzira Bainite isothermal quenching nzira: dzima iyo workpiece mubhati pane yakaderera bainite tembiricha yesimbi kune isothermal, kuitira kuti igone kupinda yakaderera bainite shanduko, uye kazhinji kuichengeta mubhavhu kwe30 ~ 60min. Iyo bainite isothermal quenching process ine matanho makuru matatu: ① austenitizing; ② Kutonhora kurapwa mushure me austenitization; ③ Bainite isothermal kurapwa; Inowanzo shandiswa mu alloy simbi, yakakwira kabhoni simbi diki saizi zvikamu, uye ductile iron castings. 6、 Composite quenching nzira

Compound quenching nzira: iyo workpiece inodzimwa kusvika pazasi Ms kuti iwane martensite ine vhoriyamu chikamu che10% ~ 30%, uyezve isothermal munzvimbo yepasi bainite kuti iwane martensite uye bainite zvimiro zvemaworkpiece ane makuru makuru emuchinjikwa, ayo anowanzo kushandiswa alloy tool simbi workpieces. 7、 Precooling Isothermal Quenching Method Precooling Isothermal Quenching Method: Iyo inozivikanwawo seTemperature Rise Isothermal Quenching, zvikamu zvinotanga kutonhodzwa mutembiricha yakaderera (yakakura kupfuura Ms) yekugezera, uye yozoendeswa kune yakakwira tembiricha yekugezera kuti iite isothermal shanduko yeaustenite. Inokodzera mativi esimbi asina kuomarara kana zvidimbu zvebasa zvine hukuru hukuru hunoda isothermal quenching.

8、 Kunonoka kutonhora kudzima nzira

Kunonoka kutonhora kudzima nzira: Zvikamu zvakafanotonhodzwa kusvika kune tembiricha yakakwira zvishoma kupfuura Ar3 kana Ar1 mumhepo, mvura inopisa, kana yekugezesa munyu, uye yobva yaiswa pasi pekudzima kumwe chete. Inowanzo shandiswa kune zvikamu zvine maumbirwo akaomarara, kusiyanisa ukobvu muzvikamu zvakasiyana, uye zvinoda kushoma deformation.

9, Kudzima nzira yekudziya: Kupisa ese akagadziridzwa workpieces, asi panguva yekudzima, chete zvikamu zvinoda kuomeswa (kazhinji zvikamu zvinoshanda) zvinonyudzwa mukudzima mhinduro yekutonhodza. Mirira kusvikira zvikamu zvisina kunyudzwa zvanyangarika, uye pakarepo zvibvise kuti zvitonhore mumhepo. Nzira yekudzima uye yekuzvipisa inoshandisa kupisa kusati kwanyatsotonhodzwa kuburikidza nepakati kuti iende pamusoro pepamusoro, zvichiita kuti pasi riongororwe. Zvishandiso zvinowanzo shandiswa kushingirira kusimba, semachizi, zvibhakera, sando nezvimwe.、 Spray quenching method: Nzira yekudzima iyo mvura inopfapfaidzwa pane workpiece, uye kuyerera kwemvura kunogona kuva hombe kana diki, zvichienderana nekudzika kunodiwa kwekudzima. The pfapfaidzo quenching nzira haina kuumba mhute firimu pamusoro pemvura workpiece, iyo inova nechokwadi chokuti yakadzika kuomeswa layer inowanikwa pane quenching mumvura Xitong. Inonyanya kushandiswa kudzima pamusoro penzvimbo.
