Kev ua tau zoo specifications
Cov ntawv txias dov muaj kev ua tau zoo, uas yog, los ntawm txias dov, txias-dov strip steel thiab steel phaj nrog thinner thickness thiab siab dua precision yuav tau. Nws muaj qhov flatness siab, siab nto smoothness, huv si thiab ci ntsa iab, yooj yim txheej ua, ntau yam, thiab dav siv. Nyob rau tib lub sijhawm, nws muaj cov yam ntxwv ntawm kev ua haujlwm siab stamping, tsis muaj kev laus, thiab qhov taw tes qis. Yog li ntawd, cov ntawv txias txias muaj ntau yam kev siv, feem ntau yog siv hauv kev lag luam xws li tsheb, luam ntawv hlau nruas, kev tsim kho, cov khoom siv hauv tsev, tsheb kauj vab, thiab lwm yam. Nws kuj yog cov khoom siv zoo tshaj plaws los ua cov organic coated steel daim hlau.
Kev tsis xws luag
Ntug crack defect
Kev txhawb nqa loj ntawm cov npoo ntawm cov npoo yog ib qho ntawm cov laj thawj tseem ceeb ntawm ntug kev tawg. Vim yog siv cov funnel-puab crystallizer nyob rau hauv nyias slab casting, qhov tsis sib xws ntws thiab cua sov hloov mus rau hauv lub crystallizer, nrog rau kev hloov ntawm cov kua theem, yog complex tshaj li cov tsoos slab nruam casting. Thaum lub sij hawm casting txheej txheem, slag entrapment feem ntau tshwm sim, thiab ib feem ntawm cov slag entrapment tseem nyob rau ntawm qhov chaw ntawm lub slab, tsim deg inclusions. Cov khoom loj dua tuaj yeem tso rau ntawm cov npoo ntawm cov nplais, uas ua rau muaj kev nplua nuj ntawm cov oxide loj ntawm cov npoo.
Hlau oxide nplai indentation defect
Kev tshem tawm tsis tiav ntawm cov hlau oxide nplai raug nias rau hauv lub sawb thaum lub sij hawm tom qab dov txheej txheem, ua rau muaj qhov tsis xws luag ntawm lub sawb. Qhov tsis tuaj yeem qhib qhov dej thib ob descaling thiab lwm yam laj thawj yog qhov tseem ceeb uas ua rau qhov tsis xws ntawm cov hlau oxide theem nrab raug nias rau hauv. Qhov kev soj ntsuam tsis raug qhia tau hais tias cov hlau oxide nplai indentation tsis raug tuaj yeem raug tshem tawm thaum lub sij hawm tom qab pickling thiab txias dov. cov txheej txheem, thiab muaj kev cuam tshuam me ntsis ntawm lub phaj txias-dov.
Deg tsis xws luag
Dub linear tsis xws luag nyob rau saum npoo ntawm lub sawb hlau ua ntej txias dov tom qab pickling. Qhov tsis xws luag ntawm cov khaub thuas dov strip steel feem ntau yog los ntawm qhov tsis xws ntawm cov ntaub ntawv kub dov hauv paus, nrog rau kev sib xyaw ntawm cov phaj kub-kuav los tiag yog hom kev tsis xws luag. Qhov muaj peev xwm ntawm qhov tsis xws luag tshwm sim ntawm cov kab mob khaub thuas-kuav los tiag nws tus kheej yog qhov tsawg heev.
