Kev soj ntsuam ntawm kev tiv thaiv kev ntsuas rau stamping cracking ntawm galvanized ntawv

Xov xwm

Cov txheej txheem ntawm cov kab galvanizing yog raws li nram no: txias yob → degrease → nruam annealing → galvanizing → xov → nro thiab leveling → roller txheej → induction cua sov → cua txias → zoo soj ntsuam → txheej, hnyav thiab ntim.Nyob rau hauv nws cov ntau lawm, nws yog ib qho yooj yim kom muaj stamping cracking tsis xws luag, uas cuam tshuam rau cov neeg siv ntau lawm.Qhov ua rau yog
1. Annealing kub
Qhov kub kub heev yog qhov txheej txheem tseem ceeb hauv cov txheej txheem galvanizing, thiab qhov kub ntawm annealing muaj qhov cuam tshuam zoo rau lub zog ntawm cov khoom.Thaum lub annealing kub yog tsawg, lub annealing tsis txaus, lub grain loj me me, lub zog yog siab, thiab elongation yog tsawg;Yog hais tias qhov kub ntawm annealing yog siab, nws yog ib qho yooj yim uas yuav ua rau lub grain loj yuav txawv txawv coarse thiab lub zog ntawm cov zis khaub ncaws yuav txo tau.
Nyob rau tib lub sijhawm, lub zog tensile tau poob qis dua, thiab cov khoom lag luam tuaj yeem cuam tshuam ncaj qha thaum lub sij hawm stamping thiab stretching txheej txheem ntawm cov neeg siv khoom.
2. Machining lubrication
Qhov saum npoo roughness ntawm cov khoom yuav cuam tshuam rau cov roj cia muaj peev xwm ntawm nws qhov chaw.Qhov zoo ntawm qhov roughness ntawm cov hlau kauj kuj tseem ceeb heev rau kev ua haujlwm ntawm cov khoom siv.Nyob rau tib lub sijhawm, kev xaiv ntawm cov roj siv yog qhov tseem ceeb heev.Yog tias cov roj siv tsawg dhau, cov khoom siv yuav tsis txaus lubricated thaum lub sij hawm stamping, uas yuav ua rau cov khoom stamping.
tawg;Yog tias siv roj ntau dhau lawm, nws yooj yim rau plam thaum lub sijhawm slitting thiab tsim, cuam tshuam rau cov khoom sib dhos.
3. Khoom thickness thiab tuag clearance haum
Nyob rau hauv cov txheej txheem ntawm cov ntaub ntawv stamping, qhov sib txuam ntawm kev tuag clearance thiab cov ntaub ntawv thickness kuj yog ib qho tseem ceeb uas ua rau cov khoom tawg.
4. Kev tswj qhov tsis xws luag xws li suav nrog
Qhov tsis xws luag xws li suav nrog thiab txawv teb chaws xovxwm yog qhov tsis zoo rau cov khoom siv stamping.Vim hais tias lub zos elongation ntawm cov inclusion tsis txaus, nws yog ib qho yooj yim los tsim stamping thiab tensile cracking.
Raws li kev soj ntsuam saum toj no, cov kev ntsuas hauv qab no tuaj yeem raug coj los ua kom tsis txhob muaj qhov tawg ntawm cov ntawv galvanized
1. Cov nroj tsuag steel yuav tsum teeb tsa qhov tsim nyog galvanizing annealing kub, thiab lub hom phiaj tus nqi yuav tsum tau tswj ntawm li 850 ℃, thiab kev ruaj ntseg ntawm qhov kub thiab txias yuav tsum lav;
2. Xaiv cov roj stamping kom raug thiab muab cov roj tsim nyog;
3. Lub zog dov ntawm lub tshuab ua tiav yuav tsum tswj tau siab tshaj 1200kN;
4. Cov kev suav nrog yuav tsum tau tswj nyob rau hauv cov txheej txheem steelmaking kom huv si ntawm molten steel;
5. Nkag siab txog cov pwm siv thiab xyuas kom meej qhov sib piv ntawm pwm tshem tawm, cov khoom deformation muaj peev xwm thiab cov khoom tuab
