Yuav ua li cas paub qhov txawv ntawm anealing, normevers, quenching, thiab tempering ...
Aug 13, 2025
Annealing, noraling, quenching, thiab tempering ... Koj puas paub qhov sib txawv ntawm kev kho cua sov no? Kev kho cua sov txhim kho cov khoom siv tshuab cov tshuab ntawm cov ntaub ntawv, tshem tawm cov khoom siv ntxhov siab, thiab txhim kho cov tshuabsab ntawm cov hlau. Raws li lawv cov hom phiaj sib txawv, cov txheej txheem kho cua sov tuaj yeem faib ua ob pawg: kev kho cua sov ua ntej thiab kev kho cua sov ua ntej.
01 Kev Kho Mob Cua Sov
Lub hom phiaj ntawm kev kho cua sov ua ntej yog txhawm rau txhim kho kev ntxhov siab, tshem tawm cov kev ntxhov siab sab hauv, thiab npaj ib qho kev sib cav sib ceg sab hauv rau kev kho cua sov kawg. Cov txheej txheem kho cua sov muaj xws li annealing, normevers, kev laus, thiab temperinging.
1) annealing thiab normizing
Annealing thiab noralizing yog ua rau kub -}}} ua haujlwm tsis muaj dab tsi. Cov hlau roj carbon hlau thiab cov hlau sib txuas nrog cov ntsiab lus carbon ntau dua 0.5% feem ntau muaj kev cuam tshuam rau txo lawv lub hardness. Cov hlau roj carbon thiab cov hlau sib txuas nrog cov ntsiab lus carbon tsawg dua 0.5% yog qhov ua kom tiv thaiv lub hardness los ntawm kev txiav thaum lub sijhawm txiav. Annealing thiab ib txwm ua tau ua kom cov qoob loo loj thiab homogenize lub microstructize, npaj rau kev kho cua sov tom ntej. Annealing thiab normizing feem ntau ua tau tom qab kev tsim khoom dawb thiab ua ntej ntxhib machining.
2) Kev Kho Mob Laus
Kev laus yog feem ntau siv los tshem tawm sab hauv kev ntxhov siab tsim tawm thaum lub tshuab luam ntawv dawb thiab machining.
Txhawm rau kom tsis txhob muaj tsheb thauj mus los ntau dhau, rau qhov uas yuav tsum tau ua ntej, ib qho kev laus kev kho mob ua ntej ua tiav yog qhov txaus. Txawm li cas los xij, rau qhov uas yuav tsum tau muaj qhov siab dua (xws li cov vaj tse ntawm kev ua haujlwm tho txawv kev kho mob), ob lossis ntau dua qub yuav tsum tau ua. Qhov yooj yim feem ntau tsis tas yuav muaj kev laus.
Ntxiv nrog rau castings, rau qee qhov chaw precision nrog tsawg dua li kev kho mob hnyav thiab ua tiav rau kev ntxhov siab sab hauv tsim kho kom zoo. Qee tus ncej sab kuj xav tau kev laus tom qab ncaj.
3) quenching thiab tempering
Quenching thiab tempering koom nrog ua qhov siab - sov tempering kho mob tom qab quenching. Txoj kev kho mob no ua rau muaj kev niaj hnub ua kom zoo nkauj thiab kev npaj zoo rau tom qab saum npoo hardening thiab nitrivate kev kho mob kom txo qis distortion. Yog li ntawd, quenching thiab tempering kuj tseem tuaj yeem ua kev npaj ua kom sov. Vim hais tias tag nrho cov khoom siv tshuab ntawm cov chaw tom qab quenching thiab tempering zoo heev, nws kuj tseem tuaj yeem siv ua qhov kev xav tau kub ua kom tawv thiab hnav tsis kam.
02 Thaum Tshav Kub Kub Kawg
Lub hom phiaj ntawm kev kho cua sov zaum kawg yog txhawm rau txhim kho cov khoom siv cov khoom siv xws li kev tawv, hnav tsis kam, thiab lub zog.
1) quenching
Quenching tuaj yeem muab faib ua saum npoo av thiab dhau los ntawm quenching. Nto Quenching tau siv dav siv vim tias nws minimizes deformation, oxidation, thiab decarburization. Nws tseem muaj qhov zoo ntawm lub zog siab sab nraud thiab cov hnav zoo thaum tswj hwm kev ua kom zoo sab hauv thiab cuam tshuam tsis kam. Txhawm rau txhim kho cov khoom siv ntawm nplaim av- kev kho kom sov, kev ua si ua ntej ua ntej xws li kev ua si lossis ib txwm muaj. Txoj kev txheej txheem txheej txheem dav dav yog: → → ricure (analing) → ntxhib machining tshuab → semi → nto spenching → finishing.
2) carburizing thiab quenching
Carburizing thiab quenching yog tsim nyog rau qis - carbon thiab qis-}}}}}}}}}}} cov hlau almoy. Nws ua ntej nce cov pa roj carbon cov ntsiab lus hauv txheej txheej saum npoo ntawm ib feem. Tom qab quenching, txheej saum npoo txheej ua tiav hardness thaum tus tseem ceeb khaws ib co℃ntawm lub zog, siab tawv, thiab kev du ncauj. Carburizing tuaj yeem ua nyob rau hauv ob qho tib si dav dav thiab ib feem carburizing. Thaum lub sij hawm ib nrab carburizing, tsis - cov chaw carburized koj yuav tsum tau anti {} Lub plating lossis txheej- saib cov khoom). Vim tias carburizing thiab quenching ua rau muaj kev tsis txaus siab tseem ceeb, thiab lub qhov tob carburizing feem ntau yog ib txwm ua ntawm semi- tiav thiab xov.
Cov txheej txheem txheej txheem dav dav yog: Kev Blog → Ua Forging → Reg thiab semi {{0} → carburizing thiab quenching → Tipishing. Thaum ib nrab carburizes ib feem, tsis - carburized cov chaw muaj stocked thiab tom qab ntawd cov txheej carburized dhau los yog muab tshem tawm. Qhov kev tshem tawm no yuav tsum tau ua tom qab carburizing thiab ua ntej quenching.
3) Nitridoning Kho
Nitration yog ib txheej txheem kev kho mob hauv uas cov pa taws dos nkag mus rau cov txheej hlau los tsim ib txheej ntawm nitrogen {{}} muaj cov tebchaw. Txheej nitrived no txhim kho cov npoo tawv, hnav tsis kam, muaj zog nkees, thiab corrosion tsis kam ntawm ib feem. Txij li thaum nitrogency kev kho kub yog tsawg, qhov deformation yog me me, thiab cov txheej txheem nitrived yog ntau tshaj li 0.6 ~ Txhawm rau txo cov deformation thaum nitriving, siab - kub siab yog feem ntau yuav tsum tau pom kev ntxhov siab tom qab txiav.
