Kub ua hauj lwm thiab kev kho cua sov kub
Mos Annealing
Kub rau 650-700oC.
Carburizing
Qhov kub thiab txias 900-950oC. Cooing los ntawm carburizing kub: dej, roj, cua, thermal da dej, lub thawv txias.
Hardening
Core hardening 850-880oC. Case hardening: 810 -840oC. Quenching media: dej, roj, cua, thermal da dej.
Tempering
Tempering kub: 150-200oC.
Forging
Kub txheej kub: 1100-850oC.
Rolling
Rolling kub 1220oC, Tiav Templerature> 900oC
normalizing
850-880 oC, cua txias
Normalizing kuj tseem siv tau. Cov hlau yog rhuab mus rau qhov kub zoo ib yam li annealing tab sis yog txias hauv huab cua. Cov txheej txheem no ua kom zoo dua cov qauv nplej, txhim kho homogeneity ntawm microstructure, thiab txhim kho cov khoom siv kho tshuab.
Case hardening yog qee zaum siv rau cov ntawv thov tshwj xeeb. Qhov no suav nrog kev qhia cov pa roj carbon lossis lwm cov khoom tawv tawv rau cov txheej txheem ntawm cov hlau, ua raws li kev kho cua sov los tsim cov ntaub ntawv nyuaj thaum tuav cov tub ntxhais tawv. Feem ntau cov txheej txheem hardening rau 20MnCr5 Steel muaj xws li carburizing thiab nitriding.
Carburizing cuam tshuam cov hlau mus rau qhov chaw uas muaj cov pa roj carbon ntau ntawm qhov kub thiab txias, tso cai rau cov pa roj carbon diffuse mus rau hauv txheej txheej. Tom qab ntawd, quenching thiab tempering yog nqa tawm kom ua tiav qhov xav tau hardness profile. Nitriding, ntawm qhov tod tes, qhia txog nitrogen rau hauv txheej txheej ntawm qhov kub thiab txias, uas ua rau lub ntsej muag tawv thiab hnav-resistant.
Kev xaiv cov txheej txheem kho cua sov uas tsim nyog rau 20MnCr5 Steel nyob ntawm ntau yam xws li daim ntawv thov, xav tau cov khoom siv kho tshuab, thiab cov txheej txheem tsim khoom. Ua tib zoo tswj cov kev kho cua sov, nrog rau qhov kub thiab txias, lub sijhawm, thiab qhov txias txias, yog qhov tseem ceeb los xyuas kom meej qhov xav tau microstructure thiab kev ua haujlwm ntawm cov hlau.
Hauv kev xaus, cov txheej txheem kev kho cua sov rau 20MnCr5 Steel muaj ntau txoj hauv kev los kho nws cov khoom kom tau raws li cov kev cai tshwj xeeb ntawm kev siv ntau yam. Kev tshawb fawb tsis tu ncua thiab kev txhim kho hauv kev kho cua sov thev naus laus zis txuas ntxiv txhim kho cov txheej txheem no thiab txhim kho kev ua tau zoo thiab kev ntseeg siab ntawm 20MnCr5 Steel hauv ntau daim ntawv thov engineering.
