Dab tsi yog cov txheej txheem quenching feem ntau siv rau cov khoom siv hluav taws xob ntau zaus

Feem ntau siv quenching txoj kev rau high-frequency quenching khoom yog:

1. Ib qho nruab nrab quenching

Qhov kom zoo dua ntawm ib qho nruab nrab quenching yog tias nws yooj yim rau kev khiav lag luam, tab sis nws tsuas yog tsim rau me me thiab yooj yim-zoo li tus workpieces, thiab nws yooj yim rau deformation loj thiab tawg rau cov workpieces loj.

2. Ob chav nruab nrab quenching

Muab ob npaug rau nruab nrab quenching yog kom sov lub workpiece rau austenitize thiab ces muab tso rau hauv ib qho nruab nrab uas muaj peev xwm txias txias. Thaum qhov kev hloov pauv ntawm cov qauv martensite tab tom yuav tshwm sim, nws tam sim ntawd hloov mus rau qhov nruab nrab uas muaj peev xwm ua kom tsis muaj zog kom txias mus ntxiv. Feem ntau, dej yog siv los ua qhov ceev-txias quenching nruab nrab, thiab roj yog siv los ua qhov qeeb-txias quenching nruab nrab. Qee zaum dej quenching thiab cua txias tuaj yeem siv tau. Ob chav nruab nrab quenching tuaj yeem tiv thaiv workpiece deformation thiab tawg. Cov pa roj carbon steel loj dua workpieces yog tsim rau quenching li no.

3, qib quenching

Txoj kev quenching no zoo heev txo qhov muaj peev xwm quenching vim qhov kub tsis sib xws hauv thiab sab nraud ntawm lub workpiece thiab ua tiav cov kev hloov pauv martensitic nyob rau hauv qis txias txias, yog li txo los yog tiv thaiv qhov deformation thiab tawg ntawm lub workpiece, thiab tseem overcomes qhov nyuaj ntawm kev tswj cov dej. thiab roj nyob rau hauv lub dual-medium quenching. Qhov tsis zoo. Txawm li cas los xij, vim qhov kub ntawm qhov nruab nrab ntawm qhov txias txias hauv txoj kev quenching no, qhov cua txias ntawm lub workpiece nyob rau hauv alkali da dej los yog ntsev da dej yog qeeb, yog li lub sij hawm tos yog txwv, thiab nws yog ib qho nyuaj rau qhov loj-section. ncav cuag qhov tseem ceeb quenching tus nqi. me me workpiece.

4. Isothermal quenching

Austempering tuaj yeem txo qhov deformation thiab tawg ntawm cov khoom ua haujlwm, thiab tsim nyog rau kev ua haujlwm nyuaj, siab-precision thiab tseem ceeb cov khoom siv, xws li pwm, cuab yeej, thiab lub zog. Zoo li qib quenching, isothermal quenching tsuas yog siv rau cov khoom me me xwb. Qhov nruab nrab thiab siab zaus quenching tshuab cuab yeej cuab yeej yuav tsum txiav txim siab uas quenching txoj kev siv raws li lub workpiece koj yuav tsum tau quench. Cov cuab yeej me me kuj tseem tuaj yeem ua tiav nrog ib qho xov xwm quenching.

Ntxiv rau cov txheej txheem quenching saum toj no hauv cov txheej txheem quenching ntawm high-frequency quenching tshuab cov cuab yeej, ntau cov txheej txheem quenching tshiab tau tsim los txhim kho lub zog thiab tawv ntawm cov hlau nyob rau xyoo tas los no, xws li kub kub quenching, ceev cyclic cua sov quenching, lwm.
