Annealing, noraling, quenching, tempering ...... Koj puas paub qhov txawv ntawm kev kho cua sov no? Lub luag haujlwm ntawm kev kho cua sov yog txhawm rau txhim kho cov khoom siv cua sov, kev kho kom sov raws li kev kho cua sov thiab kev npaj ua cua sov.
01 MRIM YAM KEV KHO MOV THAUM KUB
Lub hom phiaj ntawm kev npaj tshav kub yog txhawm rau txhim kho kev ntxhov siab, kev kho kom sov, kev laus, tempering thiab yog li ntawm {1}.
(1) annealing thiab li qub
Annaling thiab noralizing yog siv rau kub machined blanks {}} pa roj ntau dua 0}} pa roj hmab ntau dua 0}} pa roj hmab yooj yim, feem ntau siv anealing; Cov ntsiab lus carbon ntawm tsawg dua 0 {{4 4}}} Annealing thiab ib txwm muaj feem ntau tau npaj tom qab kev tsim cov blanks, ua ntej siv tawv tshuab.
(2) Kev Kho Mob Laus
Kev laus kev kho mob feem ntau yog siv los tshem tawm cov kev ntxhov siab sab hauv tsim tawm hauv kev tsim cov blanks thiab machining.
Txhawm rau kom tsis txhob muaj tsheb thauj mus los ntau dhau los, rau cov txheej txheem kev laus ua ntej, xws li kev ua haujlwm yooj yim tsis muaj ib qho kev kho mob ua ntej (xws li kev ua haujlwm yooj yim tsis ntev
Ntxiv rau cas rau castings, rau qee qhov tsis zoo ntawm cov kev ua haujlwm sab hauv, feem ntau yog cov khoom siv ncaj qha tsim, kev ua kom ncaj
3) Tempering
Tempering uas yog nyob rau hauv lub quenching kev kho siab kub, nws tuaj yeem tau txais kev pab cuam tshuam txog kev npaj tawm, yog li tempering kuj tseem siv tau ua kev npaj ua cua sov.
Raws li cov khoom siv tshuab ua ke ntawm cov chaw tom qab Tempering yog qhov zoo dua, rau qee qhov kev nyuaj siab thiab hnav cov txheej txheem kev kho cua sov kawg .
02 Thaum Tshav Kub Kub Kawg
Lub hom phiaj ntawm kev kho cua sov zaum kawg yog txhawm rau txhim kho lub hardness, hnav tsis kam thiab lub zog thiab lwm yam khoom siv tshuab |.
(1) quenching
Quenching muaj nto quenching thiab tag nrho quenching . kev ua kom zoo dua vim tias tsis tshua muaj zog, thiab cov khoom noj kom zoo dua qub, feem ntau yuav tsum tau ua kom sov siab lossis ib txwm muaj Kev kho cua sov raws li kev npaj ua cua sov {2} → ntxhib machining → semi-tiav semiing {} 4}}
(2) carburizing quenching
Carburizing quenching siv rau cov roj carbon hlau tsawg thiab cov txheej txheem zoo nkauj thiab lub zog ntawm carburizing ib feem ntawm qhov tsis muaj carburizing los ua kom tsis txhob muaj carburizing Kev ntsuas (tooj-plated lossis plated anti-SHATPage cov ntaub ntawv) {}}}}}}}}}}}}}
Txheej txheem txheej txheem feem ntau: cov khoom siv tau zam txim → ntxhib txheej ntawm cov txheej txheem carburized ntawm cov txheej txheem carburizing ntawm lub carburizing, quenching ua ntej .
3) Nitridoning Kho
Nitriding yog ua kom cov nitrogen atoms nkag mus rau hauv cov txheej txheem hlau ua kom muaj zog, muaj zog tsis zoo, thiab cov txheej nitroging yog nyias (feem ntau tsis muaj ntau tshaj 0 {. 6 ~ 0.7mm), cov txheej txheem nitrived, feem ntau yuav tsum tau tshem tawm cov kev txiav txim siab ntawm kev ntxhov siab.
