6. Compound quenching nzira

Compound quenching nzira: chekutanga kudzima iyo workpiece kusvika pazasi Ms kuti uwane martensite ine vhoriyamu chikamu che10% ~ 30%, uyezve isothermally munzvimbo yepasi bainite kuti uwane martensite uye bainite chimiro cheiyo workpiece ine yakakura muchinjiko-chikamu. Alloy tool simbi workpiece.

Nomwe, pre-kutonhora isothermal quenching nzira

Pre-kutonhora isothermal quenching nzira: inozivikanwawo sekudziyisa isothermal quenching, zvikamu zvinotanga kutonhodzwa mubhati ine tembiricha yakaderera (yakakura kupfuura Ms), uye yozoendeswa kune yekugezera ine tembiricha yepamusoro kuita kuti austenite iite isothermal shanduko. Inokodzera zvikamu zvesimbi zvine hurombo husina kusimba kana hukuru hukuru hwekushanda hunofanirwa kuve hutete.

Sere, kunonoka kutonhora kudzima nzira

Kunonoka kutonhora kudzima nzira: Zvikamu zvakafanotonhodzwa mumhepo, mvura inopisa, uye yekugezesa munyu kune tembiricha yakakwira zvishoma kupfuura Ar3 kana Ar1, uyezve imwe-yepakati quenching inoitwa. Inowanzoshandiswa kune zvikamu zvine maumbirwo akaoma uye zvikamu zvine hukuru hwakakura kusiyana uye diki deformation zvinodiwa.

9. Kudzima uye kuzvidzora nzira

Kudzima kuzvidzora nzira: kupisa ose workpieces kuti agadziriswe, asi chete kunyudza chikamu chinoda kuomeswa (kazhinji kushanda chikamu) ari quenching mvura kutonhora, uye kuitora kunze mumhepo kana unimmered chikamu anonyangarika. Kudzima nzira nepakati kutonhora. Iyo yekudzima yekuzvipisa nzira inoshandisa kupisa kusati kwanyatsotonhodzwa mukati kuti kufambiswe kumusoro kushatirisa pamusoro. Inowanzo shandiswa kune maturusi anotakura senge chisel, zvibhakera, sando, nezvimwe.

Gumi, pfapfaidza quenching nzira

Jet quenching nzira: Nzira yekudzima yejetting mvura inoyerera kune workpiece, mvura inoyerera inogona kuva yakakura kana diki, zvichienderana nekudzika kunodiwa kwekudzima. Iyo yekupfapfaidza quenching nzira haigadziri mhute firimu pamusoro peiyo workpiece, iyo inovimbisa yakadzika yakaomeswa layer pane iyo yekudzima mumvura yakajairika. Inonyanya kushandiswa kudzima pamusoro penzvimbo.
