Cold-rolled steel yog dab tsi?
1. Cold-rolled steel yog hlau ua los ntawm txias dov. Nyob rau hauv tej yam kev mob, cov hlau phaj tuaj yeem raug nias ntxiv rau hauv qhov xav tau tuab. Piv nrog rau cov hlau kub nias, nws cov thickness yuav ntau meej, thiab nto yuav smoother thiab zoo nkauj dua.
2. Nyob rau tib lub sijhawm, nws tseem tswj kev ua haujlwm ruaj khov, xws li kev ua haujlwm zoo heev, tab sis tsis tsim nyog rau kev ua haujlwm, yog li nws yuav tsum tau annealed ua ntej nws tuaj yeem xa mus rau cov neeg siv khoom. Qhov tuab yog loj thiab me, xws li qhov tsawg tshaj plaws yog 0.1 hli thiab qhov loj tshaj plaws yog li 8 hli.
ST12 yog zoo tib yam txias-kuav los tiag steel, uas belongs rau tus qauv German. Kuj tseem muaj ST13 lossis ST14. Cov ntaub ntawv ntawm ob qho tib si kuj txawv. Piv txwv li, ST13 belongs rau qib stamping, thiab ST14 belongs rau qib sib sib zog nqus. Raws li cov yam ntxwv ntawm kev ua haujlwm ntawm cov khoom siv no, lub zog tawm los yog nyob rau hauv 280MPA, lub zog tensile ntawm 270 ~ 410MPA, thiab elongation tom qab tawg yog tswj ntawm 80 hli.

GNEE feem ntau cuam tshuam rau hauv: carbon steel, galvanized, PPGL xim-coated coils, daim hlau, thiab lwm yam. thiab cov khoom siv sib sib zog nqus tau raug xa tawm mus rau Middle East, North America, South America, Europe, Africa, Australia thiab lwm thaj chaw, tsim lub ntiaj teb. kev lag luam network.
GNEE tau tsim cov tsev khaws khoom loj qhib dav hlau niaj hnub thiab cov tsev khaws khoom hauv tsev, nrog 20, 000 tons ntawm cov khoom muaj.
