Abstract:In order to study the effect of coiling temperature on batch annealing recrystallization process of high strength IF steel 250P1, using the nitrogen heating furnace to simulate the batch annealing process, the recrystallization law of high strength IF steel 250P1 containing phosphorus was studied on the condition of high coiling temperature and low coiling temperature. The texture analysis of 700 ℃ annealing plate and finished plate were carried out by X- ray diffraction. And the microstructure of the finished plate was observed. The results showed that the recrystallization temperature of cold rolling plate with low coiling temperature and high coiling temperature were about 675 and 700 ℃, respectively. The annealing plate with low coiling temperature had the advanced {111} texture with high strength, higher {111}/{100} ratio and r value, and larger microstructure grain size.
