Lub yob yog ib qho cuab yeej ua rau cov hlau tsim cov yas deformation.Nws yog ib qho tseem ceeb ntawm cov khoom siv uas txiav txim siab qhov ua tau zoo ntawm cov dov zeb thiab qhov zoo ntawm cov khoom dov.Cov yob yog ib qho tseem ceeb ntawm cov dov zeb hauv cov dov zeb.Lub siab ua los ntawm ib khub lossis pab pawg yob yog siv los yob cov hlau.Nws tsuas yog dais lub dynamic thiab zoo li qub loads, hnav thiab kub hloov thaum dov.
Peb feem ntau siv ob hom yob, yob txias thiab yob kub.
Muaj ntau ntau hom khoom siv rau cov yob yob yob, xws li 9Cr, 9cr2,9crv, 8crmov, thiab lwm yam. Muaj ob qhov kev xav tau rau hom yob no.
1: Lub nto ntawm lub yob yuav tsum tau quenched
2: Lub hardness saum npoo yuav tsum yog hs45 ~ 105.
Cov ntaub ntawv uas ua los ntawm kub dov yob feem ntau muaj xws li 60CrMnMo, 55mn2, thiab lwm yam. Hom yob no yog siv nyob rau hauv ntau qhov chaw.Nws tuaj yeem siv rau hauv qee qhov kev ua haujlwm xws li ntu steel, bar steel, deformed steel, high-speed hlau, seamless steel yeeb nkab, billet, thiab lwm yam. nws bears muaj zog dov quab yuam, hnyav hnyav thiab thermal qaug zog.Ntxiv mus, cov yob kub ua haujlwm ntawm qhov kub thiab txias thiab tso cai rau txoj kab uas hla coj mus rau hauv chav ua haujlwm.Yog li ntawd, nws tsis xav tau deg hardness, tab sis tsuas yog siab zog, toughness thiab kub tsis kam.Qhov kub dov yob tsuas yog normalized los yog quenched tag nrho, thiab lub hardness ntawm lub saum npoo yuav tsum yog hb190 ~ 270.
Feem ntau cov ntawv tsis ua haujlwm thiab ua rau cov yob yog raws li hauv qab no:
1. Kev tawg.
Cov kab nrib pleb yog feem ntau tshwm sim los ntawm lub zog hauv zos ntau dhau thiab ceev ceev txias thiab cua sov ntawm cov menyuam.Ntawm lub tshuab dov, yog tias lub emulsion nozzle raug thaiv, uas ua rau cov cua txias hauv zos tsis zoo ntawm cov yob, cov kab nrib pleb yuav tshwm sim.Vim tias qhov kub tsis tshua muaj nyob rau lub caij ntuj no, cov kab nrib pleb yuav tshwm sim ntau dua li lub caij ntuj sov.
2. Peeling.
Yog tias qhov tawg txuas ntxiv tsim, nws yuav tsim thaiv los yog daim ntawv tev tawm.Cov neeg uas muaj lub teeb tev tuaj yeem txuas ntxiv siv tom qab rov ua dua, thiab cov yob nrog hnyav tev yuav raug muab pov tseg.
3. Kos ib lub qhov.
Kev kos npe hauv qhov tsuas yog vim qhov sib koom ua ke ntawm cov sawb hlau lossis lwm yam khoom siv nkag mus rau hauv lub tshuab dov, kom lub yob nto yog cim nrog cov pits ntawm cov duab sib txawv.Feem ntau, cov yob nrog pits yuav tsum tau hloov.Nyob rau hauv cov ntaub ntawv uas tsis zoo weld zoo ntawm sawb hlau, thaum lub dov ua hauj lwm dhau lub weld, nws yuav tsum tau lifted thiab nias cia kom tsis txhob khawb qhov khawb.
4. Muab lub yob.
Yog vim li cas rau lo rau yob yog vim hais tias thaum lub sij hawm txias dov txheej txheem, tawg tawg, yoj folding thiab tawg npoo tshwm sim, thiab thaum lub siab kub siab thiab instantaneous kub tshwm sim, nws yog heev yooj yim los tsim cov kev sib txuas ntawm cov hlau sawb thiab yob. , ua rau me me-qhov kev puas tsuaj rau yob.Los ntawm kev sib tsoo, cov menyuam tuaj yeem siv tau dua tom qab tshem tawm qhov tawg, tab sis nws lub neej kev pab cuam tau txo qis, thiab nws yooj yim rau tev tawm hauv kev siv yav tom ntej.
5. Cov menyuam.
Cov sliver yob feem ntau yog tshwm sim los ntawm kev txo qis ntau dhau, ua rau ob daim tawv nqaij los yog me ntsis folding ntawm cov sawb hlau thiab sib txawv ntawm cov sawb hlau.Thaum yob stranding loj heev, yob sticking tshwm sim thiab lub sawb hlau yog tawg.Thaum cov menyuam yog me ntsis khoov, muaj cov kab ntawm cov hlua hlau thiab cov menyuam.
6. Roll so.
Qhov laj thawj tseem ceeb ntawm kev sib tsoo ntawm cov yob yog overpressure (xws li lub siab dov ntau dhau), qhov tsis xws luag hauv cov yob (tsis yog xim hlau inclusions, npuas, thiab lwm yam) thiab qhov kev ntxhov siab tshwm sim los ntawm qhov tsis sib xws ntawm yob.
