The hood type furnace annealing process at 700 °C of 1.9 mm and 1.0 mm thin sheet cold rolled with 62. 0% and 71.4% reduction of ultra-low carbon steel DC01 ( 0. 047% C ) and SPCC (0. 041 % C ) produced by CSP process at Baotou Iron and Steel Co has been simulated in laboratory by electric resistance furnace. Results show that the main textures of annealed cold rolling sheet are {111}〈110〉and {111}〈112〉 ； the orientation density of {112}〈110〉 in cold rolling sheet with reduction 71.4% annealed with faster heating rate is greatest

the proportion of large-angle grain boundary is larger

the density of textures is higher and the texture mainly concentrates near the -y orientation fibre.
