| titleOfInvention | A kind of tensile strength 390MPa grades of automobile alloyed zinc hot dip galvanized steel and production method |
| abstract | The alloyed zinc hot dip galvanized steel of a kind of tensile strength 390MPa grades of automobile, its component and wt% are：C：0.07 ~ 0.10%, Si：≤ 0.03%, Mn：0.7 ~ 1.0%, P：0.010 ~ 0.025%, S≤0.010%, Als：0.020~0.070%；Production stage：Molten iron is pre-processed；Converter smelting and the processing of RH stoves；Continuous casting；To heating strand；Hot rolling；Batch；Pickling；Cold continuous rolling；Continuous annealing；Galvanizing；Alloying；Finishing；Online directly roller coat self-lubricating coating；By the drying of self-lubrication alloy plate.The present invention both can guarantee that yield strength was 290 ~ 320MPa, and tensile strength is that 390 ~ 440MPa, elongation percentage >=36%, 0.4 ~ 1.0 μm of roughness, PC value >=90, and composition and technique are simple, advantage of lower cost；Also have preferable plasticity concurrently, while by direct roller coat self-lubricating film, make efflorescence rank be upgraded to 1 grade, anti-grinded hardness index is excellent, can coin complex car inner plate and structural member. |
