Qhov zoo, qhov tsis zoo thiab daim ntawv thov ntawm cov ntawv txias dov steel & coils

Qhov zoo, qhov tsis zoo thiab kev siv ntawm cov ntawv txias txias

Cold dov yog kub dov kauj ua raw khoom, dov nyob rau hauv chav tsev kub ntawm recrystallization kub hauv qab no, txias dov steel phaj yog tsim los ntawm cov txheej txheem txias dov, hu ua txias phaj. Lub thickness ntawm txias dov steel phaj yog feem ntau ntawm 0.1-8.0mm, feem ntau factories tsim txias dov steel phaj thickness ntawm 4.5 hli los yog tsawg dua, lub thickness thiab dav ntawm txias dov steel phaj yog raws li cov nroj tsuag cov cuab yeej muaj peev xwm thiab kev lag luam xav tau thiab txiav txim siab. .

Cold Rolling yog cov txheej txheem ntawm kev ua kom cov ntawv hlau ntxiv rau lub hom phiaj tuab hauv qab qhov kub ntawm recrystallization ntawm chav tsev kub. Piv nrog kub dov steel phaj, txias dov steel phaj yog qhov tseeb dua nyob rau hauv thickness thiab muaj ib tug du thiab zoo nkauj nto.

Cold Rolled phaj zoo thiab qhov tsis zoo

1 qhov zoo

(1) ceev molding ceev, siab yield.

(2) txhim kho cov ntsiab lus ntawm cov hlau: txias dov tuaj yeem ua rau cov hlau los tsim cov yas loj deformation.

2 qhov tsis zoo

(1) cuam tshuam rau tag nrho thiab hauv zos buckling yam ntxwv ntawm steel.

(2) tsis zoo torsional zog: yooj yim torsion thaum khoov.

(3) me me phab ntsa thickness: tsis muaj thickening nyob rau hauv lub phaj articulation, tsis muaj zog muaj peev xwm los tiv thaiv localized concentrated loads.

Daim Ntawv Thov Txias Rolled Sheet thiab Cold Rolled Sawb muaj ntau yam kev siv, xws li tsheb tsim, khoom siv hluav taws xob, dov Tshuag, aviation, precision instrumentation, zaub mov kaus poom thiab lwm yam. Cold rolled nyias steel ntawv yog cov ntawv luv ntawm cov ntawv txias dov ntawm cov pa roj carbon zoo tib yam, tseem hu ua cov ntawv txias dov, uas qee zaum tsis raug raws li cov ntawv txias dov. Cov phaj txias yog tsim los ntawm cov pa roj carbon zoo tib yam steel kub dov steel sawb, tom qab ntxiv txias dov ua kom lub thickness tsawg dua 4 hli steel phaj. Vim yog dov nyob rau hauv chav tsev kub, tsis tsim hlau oxide, yog li ntawd, txias phaj saum npoo zoo, siab qhov tseeb, ua ke nrog kev kho annealing, nws cov khoom siv thiab cov txheej txheem zoo dua li cov ntawv kub dov, nyob rau hauv ntau qhov chaw, tshwj xeeb tshaj yog nyob rau hauv cov khoom. teb ntawm cov khoom siv hauv tsev tsim khoom, tau maj mam siv nws los hloov cov ntawv kub dov.
