Tsawg kubcarbon steel yeeb nkabyog cov pa roj carbon monoxide steel, tsis tshua muaj kub carbon steel yeeb nkab ua haujlwm nyob rau hauv qhov kub thiab txias, uas tuaj yeem tiv taus qee qhov kub thiab txias, kev ua haujlwm zoo dua, thiab tus nqi qis, qhov dav, yog li siv dav.Nws qhov tsis muaj zog tshaj plaws yog qhov tsis tshua muaj zog, ntu loj Japanese siab xav tau ntawm cov khoom ua haujlwm yuav tsum tsis txhob siv.
Tsawg kub carbon steel yeeb nkab quenching kub nyob rau hauv A3 + (30 ~ 50) ℃, nyob rau hauv kev xyaum, feem ntau yog teem rau sab sauv txwv.High quenching kub kub yeeb nkab tuaj yeem ua rau qis qis, txo qis oxidation, thiab tuaj yeem txhim kho kev ua haujlwm.Lub workpiece yog uniform austenite, yuav xav tau lub sij hawm tuav txaus.Yog hais tias qhov tseeb qhov cub hluav taws xob muaj peev xwm, yuav tsum tsim nyog kom ncua sij hawm tuav.Txwv tsis pub, tej zaum yuav tsis txaus hardness vim cua sov tsis sib xws los ntawm qhov tshwm sim.Txawm li cas los xij, lub sijhawm tuav ntev dhau lawm, tseem yuav tshwm sim coarse nplej, oxidation thiab decarbonization mob hnyav cuam tshuam rau quenching zoo.Peb ntseeg hais tias yog tias lub cub tawg tau teeb tsa ntau dua li cov txheej txheem cov ntaub ntawv, cov cua sov tuav lub sij hawm yuav txuas ntxiv 1/5.Tsawg kub carbon steel yeeb nkab vim tsis tshua muaj hardenability, nws yuav tsum tau txais ib tug loj txias tus nqi ntawm 10% ntsev tov.Workpiece rau hauv dej, yuav tsum hardenability, tab sis tsis chilled, yog hais tias 45 # precision steel chilled nyob rau hauv brine, nws yog ua tau tawg ntawm lub workpiece, qhov no yog vim hais tias thaum lub workpiece txias mus txog 180 ℃, lub austenite sai hloov mus rau nees lub cev. cov ntaub so ntswg los ntawm kev ntxhov siab ntau dhau vim.Yog li ntawd, thaum lub quenching thiab tempering hlau sai sai txias rau qhov kub thiab txias, txoj hauv kev yuav tsum tau ua kom txias txias.Raws li cov dej kub tsis yooj yim rau kev tuav, kev lav phib xaub hauv kev ua haujlwm, thaum cov dej tso tseg cov khoom cuav, koj tuaj yeem ua dej txias (xws li roj txias tuaj yeem ua tau zoo dua).Tsis tas li ntawd, lub workpiece mus rau hauv dej, qhov tsim nyog yuav tsum tseem ua raws li cov geometry ntawm lub workpiece, raws li ib txwm ua.Cov cua txias nruab nrab ntxiv rau qhov chaw ua haujlwm ruaj khov, ua rau qhov tsis sib xws, kev ntxhov siab tsis sib xws, tawm hauv qhov loj deformation ntawm workpiece, thiab txawm tawg.
Tsawg kub carbon steel yeeb nkab cov tswv cuab quenched hardness tom qab quenching yuav tsum ncav cuag HRC56 ~ 59, muaj peev xwm ntawm loj cross-section qis, tab sis tsis tsawg tshaj li HRC48, txwv tsis pub, nws qhia tau hais tias lub workpiece tsis tau tag nrho hardened, lub koom haum tej zaum yuav ferrite los yog sorbite. cov ntaub so ntswg, xws li cov koom haum los ntawm tempering, tseem khaws cia nyob rau hauv lub matrix, uas yog tsis quenched lub hom phiaj.Tsawg carbon steel yeeb nkab tempering tom qab quenching, cua kub feem ntau yog 560 ~ 600 ℃, hardness yog HRC22 ~ 34. Vim hais tias lub hom phiaj yog kom tau quenched txhua yam khoom, yog li muaj ntau yam hardness.Tab sis kev kos duab yuav tsum muaj hardness, nws yog ib qho tsim nyog los kho qhov kub thiab txias raws li cov duab kos kom ntseeg tau tias hardness.Raws li qee qhov txias steel shafts xav tau lub zog siab, hardness siab;thaum ib co iav keyway ncej qhov chaw, vim hais tias txawm tom qab lub milling quenched, ntxig ua, hardness yuav tsum tau rau qis dua.Txog Tempering lub sij hawm, nyob ntawm qhov hardness thiab loj ntawm workpiece, peb ntseeg hais tias, nyob ntawm qhov hardness tom qab tempering tempering kub thiab tempering me ntsis sij hawm, tab sis yuav tsum tau rov qab los ntawm lub general ib txwm ua hauj lwm Tempering sij hawm ib teev los yog ntau tshaj.
