| titleOfInvention | A kind of special extra deep drawing sheet steel of the electrogalvanizing on high roughness surface and production method |
| abstract | A kind of special extra deep drawing sheet steel of the electrogalvanizing on high roughness surface, its component and wt% are：C≤0.0018%, Si≤0.015%, Mn：0.05 ~ 0.18%, P≤0.015%, S≤0.010%, Nb：0.03 ~ 0.05%, Als：0.02~0.05%, N≤0.003%；Production method：Smelting, strand, hot rolling and cold rolling；Continuous annealing；It is smooth；After being cleaned through alkali cleaning, scrub, electrolytic degreasing and rinsing process, using gravitational method electrogalvanizing；It is stand-by.The present invention makes perpendicular to rolling direction on the premise of ensureing mild steel matter using mechanical property and with outside good tensile property：Yield strength=110 ~ 170MPa, tensile strength=260 ~ 330MPa, plastic strain ratio r 90 >=2.5, work hardening index n 90 >=0.22, elongation percentage A 80 Under mm >=43%, the roughness Ra of surface of steel plate is also set to be not less than 0.9 μm, plating coating bonding force is strong. |
