Main Features
1.Environmental protection: can effectively reduce environmental pollution.
2.Corrosion resistance: Strong anti-fouling, acid, corrosion, wear resistance, non-radioactive.
3.Surface cleanliness: The product surface is smooth and compact, not easy to be polluted by dust, and has good self-cleanliness.
4.Easy Maintenance: A slight loss is easy to repair.
1) hot-rolled pickling plate (coil) 1D: EAF -- VOD/AOD+LF (ESR for higher requirements) -- continuous casting CC -- billet heating -- descaling -- roughing (hot) -- finishing (hot) -- annealing -- pickling
