Annealing ntawm txias kos hlau
Lub annealing ntawm txias drawn steel yog feem ntau siv nyob rau hauv zus tau tej cov txheej txheem kev kho cua sov ua ntej.Feem ntau ntawm cov khoom siv tshuab thiab engineering, pwm ntxhib tuaj yeem tshem tawm cov kev ntxhov siab sab hauv thiab muaj pes tsawg leeg ntawm casting, forging thiab weldment inhomogeneity;tuaj yeem txhim kho thiab kho cov khoom siv hlau steel, thiab cov koom haum npaj rau cov txheej txheem tom ntej ua tom qab annealing.Kev ua tau zoo ntawm qhov xav tau tsawg dua, qhov tseem ceeb tsawg dua thiab qee qhov zoo tib yam castings, weldments, annealing tuaj yeem siv los ua kev kho cua sov zaum kawg.

Lub annealing ntawm steel yog rhuab mus rau ib tug haum kub, tuav ib tug tej lub sij hawm ntawm lub sij hawm, thiab ces maj mam txias thiaj li yuav tau nyob ze rau cov txheej txheem kev kho cua sov ntawm ib tug balanced lub koom haum.Lub hom phiaj ntawm annealing yog cov tshuaj lom neeg muaj pes tsawg leeg, txhawm rau txhim kho cov khoom siv kho tshuab thiab cov txheej txheem kev ua haujlwm, tshem tawm lossis txo kev ntxhov siab thiab ua kom lub koom haum npaj rau kev kho cua sov kawg ntawm qhov chaw.Cov txheej txheem annealing yog ntau hom hlau, cov cua kub cua sov tuaj yeem muab faib ua ob pawg: ib qho yog nyob rau hauv annealing saum qhov kub thiab txias (Ac3 lossis Ac1), tseem hu ua theem hloov recrystallization annealing.Nrog rau tag nrho annealed, tag nrho annealed, isothermal annealing, pob annealing thiab diffusion annealing;Lwm qhov yog qhov kub thiab txias (Ac1) tom qab annealing, tseem hu ua low-temperature annealing.Nrog rau recrystallization annealing, rau kev ntxhov siab thiab dehydrogenation annealing.Txoj kev ua kom txias tuaj yeem muab faib ua kom txias txias annealing thiab isothermal annealing.

quenching ntawm txias kos hlau
Cold drawn steel quenching tseem ceeb heev nyob rau hauv cov txheej txheem kev kho cua sov, yog dav siv txheej txheem.Quenching tuaj yeem txhim kho lub zog thiab hardness ntawm cov hlau.Yog tias sib phim rau qhov sib txawv ntawm qhov kub thiab txias tuaj yeem tshem tawm lossis txo qhov kev ntxhov siab quenching, tab sis kuj muaj lub zog, hardness thiab toughness nrog, kom tau raws li cov kev xav tau sib txawv.Yog li ntawd, quenching thiab tempering yog inseparable los ntawm ob txoj kev kho cua sov.quenching cov hlau yog rhuab mus rau saum lub ntsiab lus tseem ceeb yog ntau dua qhov tseem ceeb ntawm qhov txias txias (Vc) hauv cov rwb thaiv tsev tom qab txias, thiaj li yuav tau txais cov txheej txheem kho cua sov ntawm martensite lossis qis dua bainite.
