Vim li cas cov ntaub ntawv yuav tsum tau kho cua sov?

 

Tempering feem ntau yog hais txog cov txheej txheem ntawm quenching thiab tom qab kub kub tempering ntawm steel. Nws yog ib qho txheej txheem hauv kev kho cua sov steel. Lub hom phiaj yog txhawm rau txhim kho cov khoom siv hluav taws xob ntawm cov hlau los ntawm cov txheej txheem kho cua sov uas tsim nyog, ua rau nws muaj kev ua tau zoo txhua yam kev ua haujlwm. Hauv qab no yog cov lus qhia ntxaws ntxaws rau kev sib xyaw ua ke ntawm quenching thiab high-temperature tempering:

 

Kuv Quenching

 

▲ Kev kho cua sov

 

Lub hom phiaj

• Nce Hardness thiab Strength:Quenching hloov cov hlau austenite rau hauv martensite, ua kom cov khoom hardness thiab zog.
• Tsim ntawm Martensite Structure:Martensite qauv muaj siab hardness thiab lub zog tab sis kuj nkig.

 

Txheej txheem

• Cua sov:Cov hlau yog rhuab mus rau qhov kub austenitizing (feem ntau ntawm 750 degree thiab 950 degree), ua rau nws cov qauv sab hauv hloov mus rau hauv austenite.
• Kev txias txias:Cov hlau yog txias sai sai (feem ntau hauv dej, roj, lossis cua), hloov cov austenite rau hauv martensite.

 

Cov txiaj ntsig

• Nce Hardness:Lub hardness ntawm cov hlau yog ho txhim kho tom qab quenching, tso cai rau nws tiv taus ntau dua mechanical kev nyuaj siab.
• 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 tawg.

 

 

II Kub-kub Tempering

 

▲ Kev kho cua sov

 

Lub hom phiaj

• Txhim kho Toughness thiab Ductility:High-temperature tempering txo cov brittleness tshwm sim los ntawm quenching, txhim kho cov khoom toughness thiab ductility.
• Tshem tawm Internal Stress:Internal stresses generated thaum lub sij hawm quenching yuav ua rau cov khoom nkig. High-temperature tempering zoo tshem tawm cov kev ntxhov siab sab hauv.
• Kho Hardness:Tempering kho qhov hardness ntawm cov hlau kom tau raws li qhov xav tau kev ua haujlwm.

 

Txheej txheem

• Cua sov:Cov hlau quenched yog rhuab mus rau ntawm 500 degree thiab 650 degree thiab tuav ntawm qhov kub ntawm lub sijhawm.
• Cua txias:Feem ntau, cov hlau yog txias maj mam kom ntseeg tau cov qauv kev ruaj ntseg.

 

Cov txiaj ntsig

• Txo Hardness:High-temperature tempering moderately txo cov khoom hardness thaum tswj cov qib siab.
• Nce Toughness:Lub toughness ntawm cov hlau yog ho txhim kho tom qab tempering, ua rau nws ntau resistant rau tej yam thiab qaug zog tsis ua hauj lwm.
• Tshem tawm ntawm Internal Stress: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.

 

 

III Kev Tshaj Tawm Ntawm Tempering

 

▲ Kev kho cua sov

 

Qhov zoo

• Zoo heev Comprehensive Mechanical Properties:Steel kho los ntawm tempering muaj siab hardness, siab zog, raws li zoo raws li zoo toughness thiab ductility, raws li ib tug ntau yam ntawm daim ntawv thov xav tau kev pab.
• Dimensional Stability:By tshem tawm cov kev ntxhov siab sab hauv, cov khoom muaj kev ruaj ntseg ntawm qhov ntev thaum siv.
• Daim ntawv thov dav:Tempered steel yog tsim rau kev tsim ntau yam khoom siv xws li shafts, gears, thiab springs, thiab yog siv dav hauv kev tsim khoom, kev lag luam tsheb, aerospace, thiab lwm yam.

 

Tej kev siv

• Mechanical Parts:Cov khoom xws li cov iav, bearings, thiab cov pas nrig txuas uas xav tau lub zog siab thiab tawv.
• Cov yam ntxwv ntawm tus qauv:Cov hlau siv hauv cov qauv xws li txuas hniav thiab cov tsev, yuav tsum tau ua haujlwm ruaj khov thiab ruaj khov.
• Cov cuab yeej:Cov cuab yeej xws li cov cuab yeej txiav thiab cov pwm uas yuav tsum tau muaj zog hardness thiab hnav tsis kam.

Kev sib xyaw ua ke ntawm quenching thiab high-temperature tempering, los ntawm cov txheej txheem tempering, optimizes hardness, lub zog, thiab toughness ntawm steel, muab zoo heev zoo mechanical zog. 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.
