Cov txheej txheem annealing ntawmoxygen-dawb tooj liab stripyog ib qho tseem ceeb ntawm cov txheej txheem tsim khoom, uas tuaj yeem tshem tawm cov teeb meem ntawm cov txheej txheem uas muaj nyob rau hauv cov tooj liab sawb thiab txhim kho cov khoom siv hluav taws xob thiab hluav taws xob conductivity ntawm tooj liab.Cov txheej txheem tsis muaj oxygen-dawb tooj liab annealing yog txiav txim siab raws li qhov yuav tsum tau muaj ntawm cov khoom siv hlau, kev ua haujlwm hardening degree thiab cov khoom siv khoom.Nws cov txheej txheem tseem ceeb yog annealing kub, tuav lub sij hawm, cua kub ceev thiab txias txoj kev.Kev txiav txim siab ntawm cov txheej txheem annealing yuav tsum ua tau raws li peb qhov yuav tsum tau ua:
① Ua kom cov cua sov tsis sib xws ntawm cov khoom siv annealed kom ntseeg tau tias cov qauv zoo ib yam thiab kev ua haujlwm ntawm cov hlau tsis muaj pa oxygen;
② Xyuas kom meej tias cov hlau tsis muaj oxygen tsis muaj tooj liab tsis oxidized thiab qhov chaw ci ntsa iab;
③ Txuag lub zog, txo kev siv, thiab nce cov khoom lag luam.Yog li ntawd, cov txheej txheem annealing thiab cov cuab yeej siv rau cov hlau tsis muaj oxygen yuav tsum ua raws li cov xwm txheej saum toj no.Xws li tsim nyog rau lub cub tawg, cua kub ceev ceev, tiv thaiv huab cua, meej tswj, yooj yim hloov, thiab lwm yam.
Kev xaiv ntawm qhov kub thiab txias rau cov hlau tsis muaj pa oxygen: Ntxiv rau cov khoom siv hlau thiab cov qib hardening, lub hom phiaj ntawm kev sib tsoo yuav tsum tau txiav txim siab.Piv txwv li, qhov kev txwv sab saud ntawm annealing kub yuav tsum tau coj mus rau nruab nrab annealing, thiab lub sij hawm annealing yuav tsum tau luv luv;rau kev ua tiav annealing, ua kom pom tseeb yuav tsum tau muab tso rau hauv kev ua kom ntseeg tau cov khoom zoo thiab kev ua tau zoo Uniform, ua kom qis qis ntawm qhov kub thiab txias, thiab nruj me ntsis tswj qhov hloov pauv ntawm qhov kub thiab txias;lub annealing kub rau qhov loj ntawm tus nqi yog siab tshaj qhov kub annealing rau tus nqi me me;lub annealing kub ntawm lub phaj yog siab dua li ntawm cov hlau tsis muaj oxygen.
Annealing cua sov tus nqi: Nws yuav tsum tau txiav txim siab raws li cov khoom siv alloy, tus nqi them, cov qauv ntawm lub tshuab hluav taws xob, hom hloov hluav taws xob, hlau kub, qhov sib txawv ntawm qhov cub thiab cov khoom yuav tsum tau ua.Vim tias cov cua kub ceev tuaj yeem txhim kho cov khoom tsim tau zoo, cov nplej zoo, thiab tsawg dua oxidation, qhov nruab nrab annealing ntawm cov khoom tiav feem ntau siv cov cua sov sai;rau annealing ntawm tiav oxygen-dawb tooj liab strips, nrog tsawg nqi thiab nyias thickness, qeeb cua sov yog siv.
Tuav lub sij hawm: Thaum tsim lub qhov cub kub, thiaj li yuav ua kom lub cua sov ceev, qhov kub ntawm qhov cua sov yog siab heev.Tom qab cua sov mus rau ib qho kev ntsuas kub, nws yog ib qho tsim nyog los ua kom muaj kev txuag hluav taws xob.Lub sijhawm no, qhov cub kub kub zoo ib yam li cov khoom siv kub.Lub sijhawm tuav yog ua raws li kev ua kom lub cev kub nkag mus ntawm cov hlau tsis muaj oxygen.
Txoj kev ua kom txias: Lub annealing ntawm cov khoom tiav feem ntau yog ua los ntawm cua txias, thiab qhov nruab nrab annealing tuaj yeem ua rau dej txias.Rau cov khoom siv hlau uas muaj oxidation hnyav, lub nplai tuaj yeem tawg thiab poob rau hauv qhov txias txias.Txawm li cas los xij, alloys nrog quenching nyhuv tsis raug tso cai kom quenched.
Nyob rau hauv luv luv, cov txheej txheem annealing ntawm oxygen-dawb tooj liab sawb yog ib qho ntawm indispensable txheej txheem nyob rau hauv cov txheej txheem tooj liab sawb.Nws cov txheej txheem txheej txheem thiab cov cuam tshuam cuam tshuam yuav tsum tau ua tib zoo kawm thiab tshuaj xyuas txhawm rau tsim cov txheej txheem annealing haum rau cov khoom siv tooj liab tsis muaj oxygen.Tsuas yog los ntawm kev tshawb fawb thiab tsim nyog cov txheej txheem annealing tuaj yeem ua tau zoo oxygen-dawb tooj liab strips tsim thiab pab txhawb rau kev tsim hluav taws xob, kev sib txuas lus thiab lwm yam kev lag luam.
