Txheej txheem cej luam ntawm Cold Rolled Steel Chev

Qhov txias dov kauj yog ua los ntawm kub dov kauj. Nyob rau hauv cov txheej txheem txias dov, kub dov coil yog dov hauv qab qhov kub ntawm recrystallization, thiab feem ntau dov hlau yog dov nyob rau hauv chav tsev kub. Cov ntawv hlau uas muaj cov ntsiab lus silicon siab muaj cov brittleness thiab tsis tshua muaj plasticity, thiab yuav tsum tau preheated rau 200 ° C ua ntej txias dov. Txij li thaum lub txias dov coil tsis yog cua sov thaum lub sij hawm tsim khoom, tsis muaj qhov tsis xws luag xws li pitting thiab hlau oxide uas feem ntau pom nyob rau hauv kub dov, thiab qhov zoo ntawm qhov chaw thiab qhov kawg yog zoo.

Cold Rolled Coil Qib

1. Suav hom No. Q195, Q215, Q235, Q275 —Q — cov cai ntawm cov ntsiab lus tawm los (tso cai) ntawm cov pa roj carbon zoo tib yam steel, uas yog cov ntaub ntawv ntawm thawj Suav phonetic cov tsiaj ntawv ntawm "Qu"; 195, 215, 235, 255, 275 - raws li tus nqi ntawm lawv cov txiaj ntsig taw tes (limit), chav tsev: MPa MPa (N / mm2); vim cov khoom siv kho tshuab zoo ntawm Q235 steel lub zog, plasticity, toughness thiab weldability nyob rau hauv cov pa roj carbon zoo tib yam steel feem ntau, nws muaj peev xwm ua tau raws li cov kev cai dav dav ntawm kev siv, yog li cov peev txheej ntawm daim ntawv thov yog dav heev.

Daim ntawv thov ntawm Cold Rolled Steel Chev

Lub tshuab txias-dov coil muaj kev ua tau zoo, uas yog, los ntawm txias dov, txias-dov strip thiab steel ntawv nrog thinner thickness thiab siab dua precision yuav tau, nrog siab ncaj, siab smoothness, huv si thiab ci nto ntawm daim ntawv txias dov, thiab yooj yim txheej. Cov txheej txheem plated, ntau yam, siv dav, thiab cov yam ntxwv ntawm kev ua haujlwm siab stamping thiab tsis muaj kev laus, tsis tshua muaj qhov taw tes, yog li cov ntawv txias dov muaj ntau yam kev siv, feem ntau yog siv hauv tsheb, luam ntawv hlau nruas, kev tsim kho, khoom siv hauv tsev, tsheb kauj vab, thiab lwm yam.
