Cold drawn steel yeeb nkabyog ib hom yeeb nkab steel, uas tau muab cais raws li cov txheej txheem ntau lawm thiab txawv ntawm cov yeeb nkab kub-kuav los tiag (nthuav dav) kav.Nws yog tsim los ntawm ntau dhau ntawm kev kos duab txias thaum lub sijhawm nthuav dav cov khoom siv khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoobNtxiv rau cov kav hlau dav dav, cov kav dej qis thiab nruab nrab siab boiler steel kav, high-pressure boiler steel kav, alloy steel kav, stainless hlau kav, roj av cracking kav, mechanical processing kav, tuab phab ntsa kav, me txoj kab uas hla thiab puab pwm lwm yam steel kav. , txias dov (dov) steel kav kuj muaj xws li carbon nyias-walled steel kav, alloy nyias-walled steel kav, stainless nyias-walled steel kav, thiab tshwj xeeb-zoo li tus steel kav.Cov kav dej txias txias tuaj yeem muaj qhov ntev ntawm 6 hli, phab ntsa tuab txog li 0.25 hli, thiab cov kav dej nyias nyias tuaj yeem muaj txoj kab uas hla mus txog 5 hli nrog phab ntsa thickness tsawg dua 0.25 hli.Qhov tseeb thiab qhov zoo ntawm qhov chaw yog qhov zoo dua li cov kav dej kub dov (ntev) tab sis vim muaj kev txwv, lawv txoj kab uas hla thiab ntev yog txwv rau qee qhov.
Tus thawj high-frequency quenching tsuas yog uniformly rhuab txias drawn steel kav, tab sis tam sim no nws tau raug hloov mus rau ib tug ncaj electrification quenching txoj kev, uas ncaj qha siv high-frequency tam sim no rau cov khoom rhuab thiab generates kuj cua sov.Vim tias cov nyhuv sib thooj thiab cov nyhuv tawv nqaij, lub ntom ntom ntom tam sim no yog siab, ua rau muaj cua sov txaus thiab teenching ntawm hniav.
Qhov chaw quenching tau tsim los ntawm qhov qub tsuas yog nyob rau ntawm tus hniav nto, los ntawm cov hniav nto thiab sab nraub qaum, mus rau cov hniav nto, sab nraub qaum, thiab ncej.Sab nraub qaum thiab cov hniav yog quenched los ntawm hluav taws xob ncaj qha, thaum lub ncej tseem quenched los ntawm kev txav.
Txawm li cas los xij, thaum cov hniav nto thiab sab nraub qaum raug kho nyob rau hauv ob theem, ntxiv rau kev siv hluav taws xob ncaj qha, kuj tseem muaj txoj hauv kev quenching los ntawm kev siv lub voj voog cua sov kom txav cov khoom rhuab mus rau tib lub sij hawm cua sov ntawm cov hniav thiab sab nraub qaum (qee zaum txuas ntxiv. mus rau qhov chaw).Txoj kev no tsis tas yuav muaj cov cuab yeej compression, muaj cov khoom siv qis dua, thiab cov cua sov coil tsis cuam tshuam los ntawm cov hniav ncig thiab lwm qhov chaw, yog li nws tuaj yeem sib koom.Txawm li cas los xij, vim qhov nyuaj ntawm kev quenching hauv qab ntawm cov hniav nto, nws tseem tsis tau nce.Yuav kom daws tau cov teeb meem saum toj no, ib txoj hauv kev quenching cov hniav nto thiab rov qab ntawm cov kav dej txias txias hauv ib qho mus.
Nyob rau hauv lub xeev zoo li qub, tus neeg xyuas pib cylindrical yog energized rau lub sij hawm teem rau induce cua sov ntawm tus hniav nto thiab rov qab nto.Vim nws qhov zoo sib xws ntawm cov hniav ntawm cov hniav thiab rov qab, txhua qhov tuaj yeem sib npaug;Vim yog kev sib hloov ntawm cov khoom cua sov, qhov hluav taws xob induced yog tsim thaum dhau los ntawm qhov qis ntawm tus neeg xyuas pib cylindrical, ua rau sab kom sov, yog li cua sov cov yeeb nkab steel txias tag nrho thiab txias rau tag nrho quenching ( Yog tias nws tsis txias tom qab cua sov, tsuas yog cov hniav thiab sab nraub qaum yog quenched).Cov nyhuv thermal thaum lub sij hawm hluav taws kub yog nyob rau ntawm ib feem ntawm yav tas los quenched ib feem (feem ntau yog sab nraub qaum) Thaum lub hardness txo qis thiab cov ncej yog quenched peb zaug, nws yog ib qho tsim nyog yuav tsum ua kom cov cua sov coils haum rau ntau yam kev kho mob los txhim kho kev ua tau zoo. cev steel.
