SPCF tshwj xeeb yuav tsum tau siv txias dov kauj yog ib hom txias dov hlau raws li Japanese tus qauv, nws tsuas yog siv rau hauv kev tsim cov ntawv txias dov nws yog hom qis carbon steel qib, cov hlau xav tau muaj qhov txias txias thiab vuam kev ua tau zoo. , nrog rau qee yam kev ua haujlwm stamping. Vim tsis muaj cua sov hauv cov txheej txheem tsim khoom, yog li tsis muaj qhov kub feem ntau tshwm sim pitting thiab tin oxide thiab lwm yam tsis xws luag, zoo nto zoo, qib siab ntawm tiav. Thiab qhov loj ntawm cov khoom siv txias txias ntawm qhov siab, cov khoom ua tau zoo thiab lub koom haum tuaj yeem ua tiav qee qhov kev siv tshwj xeeb, thiab nws kuj tau siv dav, xws li kev tsim tsheb, khoom siv hluav taws xob, dov Tshuag, thiab lwm yam. Rau SPCF txias dov steel thiab strip specification cov npe, thickness ntawm 0.3-3.5 hli thiab dav ntawm 120-1850 hli yog tag nrho cov muaj nyob rau ntawm peb lub tuam txhab. Rau qhov ntev, peb kuj tuaj yeem muab raws li koj qhov yuav tsum tau ua. Cov ntaub ntawv ntau ntxiv ntawm SPCF tshwj xeeb yuav tsum tau siv txias dov coil qhia nyob rau hauv cov lus hauv qab no SPCF tshuaj muaj pes tsawg leeg:
