The structure and texture of 2.9 mm hot-rolled plate
0.9 mm cold-rolled sheet and annealed temper-rolled sheet of 0.04C low carbon steel DC03 produced by CSP process have been studied. Results showed that the structure of hot-rolled base plate was ferite matrix + a small amount of pearlite dispersed along grain-boundary
there was a little 40~ 100 nm MnS particles in ferrite matrix
and the AlN wasn't observed; the stricture of cold-rolled sheet was banded ferrite-pearlite containing a large amount of dislocation
and the {111} texture orientation was obvious in cold-rolled sheet; and the annealed temper-rolled sheet structure was ferrite and free carbide with a few of 10~30 nm precipitates
and the density of {111} was upto5.15 while the density of{100!decreased to 0.61.
