Research on cooling process and production practice of dual phase steel DP600 produced by horizontal furnace hot dip galvanizing line
To solve the problems of insufficient heating and cooling capacity in the production of hot-dip galvanized dual phase steel DP600 in a horizontal furnace,research on the production process of DP600 was carried out.This article draws the dynamic CCT curve of DP600 through component design and thermal simulation experiments,and study the effect of cooling process on the microstructure and properties of dual phase steel DP600.According to the dynamic CCT curve,combined with the heating,cooling and post-coating cooling capacity of the horizontal annealing furnace in the hot dip galvanizing line,the high-performance DP600 dual phase steel is successfully developed through the results verification of thermal simulation experiment.
