quenching thiab high-temperature tempering, feem ntau hu ua "quenching thiab tempering" txheej txheem, yog cov txheej txheem txheej txheem hauv kev kho cua sov steel. Lub hom phiaj ntawm cov txheej txheem no yog txhawm rau txhim kho cov khoom siv kho tshuab ntawm cov hlau, ua tiav kev ua haujlwm zoo tag nrho.
Nov yog cov lus qhia ntxaws ntxaws rau kev sib xyaw ua ke ntawm quenching thiab high-temperature tempering:
1 Quenching
01 Lub hom phiaj
Nce hardness thiab muaj zog: Los ntawm quenching, lub austenite nyob rau hauv steel yog hloov mus rau hauv martensite, ho nce cov khoom hardness thiab lub zog.
Form Martensitic Structure: Cov qauv martensitic muaj zog heev thiab lub zog tab sis kuj yog nkig.
2. Txheej txheem
Cua sov: Kub cov hlau mus rau qhov kub austenitizing (feem ntau ntawm 750 degree thiab 950 degree) los hloov nws cov qauv sab hauv tag nrho rau hauv austenite.
Kev txias txias: Ceev ceev cov hlau (feem ntau hauv dej, roj, lossis cua) hloov cov austenite rau hauv martensite.
03 Kev tshwm sim
Nce Hardness:Lub hardness ntawm cov hlau tseem ceeb nce tom qab quenching, cia nws tiv taus kev ntxhov siab ntau dua.
Nce brittleness:Vim muaj cov qauv ntawm martensite, lub toughness ntawm cov hlau yog txo tom qab quenching, ua rau nws yooj yim rau nkig puas.
2 High-temperature tempering
01 Lub Hom Phiaj
Txhim kho Toughness thiab Ductility:High-temperature tempering txo cov brittleness ntawm cov khoom tom qab quenching, txhim khu nws toughness thiab ductility.
Tshem tawm cov kev ntxhov siab sab hauv:Internal stresses generated thaum lub sij hawm quenching txheej txheem yuav ua rau brittleness; high-temperature tempering zoo daws cov kev ntxhov siab no.
Kho Hardness:Tempering kho lub hardness ntawm cov hlau, kom nws ua tau raws li qhov xav tau kev ua tau zoo specifications.
02 Txheej txheem
Cua sov:Ua kom sov cov hlau quenched mus rau qhov kub ntawm 500 degree thiab 650 degree, thiab tuav nws ntawm qhov kub no rau ib lub sijhawm.
Cua txias:Feem ntau, txias cov hlau maj mam kom ntseeg tau cov qauv kev ruaj ntseg.
03 Kev tshwm sim
Txo Hardness:High-temperature tempering txo cov hardness ntawm cov khoom mus rau ib tug nruab nrab theem thaum tseem tuav ib tug siab hardness.
Nce Toughness:Lub toughness ntawm steel ho txhim kho tom qab tempering, txhim khu nws tsis kam mus rau tej yam thiab qaug zog tsis ua hauj lwm.
Tshem tawm ntawm Internal Stresses:Kev tshem tawm ntawm kev ntxhov siab sab hauv yuav txo tau txoj kev pheej hmoo ntawm kev tawg thiab txhim kho qhov kev ruaj ntseg.
3 Cov txiaj ntsig zoo ntawm quenching thiab tempering
01 Qhov zoo
Zoo heev Comprehensive Mechanical Properties:Cov hlau uas tau dhau los ua quenching thiab tempering exhibits siab hardness, siab zog, nrog rau zoo toughness thiab ductility, ua rau nws haum rau ntau yam kev siv.
Dimensional Stability:Los ntawm kev tshem tawm cov kev ntxhov siab sab hauv, cov txheej txheem kom ntseeg tau tias cov khoom muaj kev ruaj ntseg ntawm qhov ntev thaum siv, txo qhov kev pheej hmoo ntawm warping lossis distortion.
Daim ntawv thov dav:Qhov kev kho no tsim nyog rau kev tsim ntau yam khoom siv, xws li shafts, gears, thiab springs, thiab yog siv dav hauv kev lag luam nrog rau kev tsim khoom, tsheb, thiab aerospace.
02 Cov ntawv thov ib txwm
Mechanical Parts:Cov khoom xws li cov iav, cov kabmob, thiab cov hlua txuas uas xav tau lub zog siab thiab tawv.
Cov yam ntxwv ntawm tus qauv:Hlau siv nyob rau hauv cov txuas hniav thiab lub tsev cov qauv uas xav tau durability thiab ruaj khov kev ua tau zoo.
Cov cuab yeej:Cov khoom xws li cov cuab yeej txiav thiab pwm uas xav tau siab hardness thiab hnav tsis kam.
03 Cov ntsiab lus
Kev sib xyaw ua ke ntawm quenching thiab high-temperature tempering, los ntawm cov txheej txheem quenching thiab tempering, optimizes steel hardness, lub zog, thiab toughness, uas ua rau cov khoom zoo heev txhua yam. Txoj kev kho no yog qhov tseem ceeb hauv kev siv cov khoom siv, kom ntseeg tau tias cov khoom siv tau ruaj khov thiab ua haujlwm ntev hauv kev siv tswv yim.
