Abstract

In accordance with experimental results about the annealing microstructure and texture of coldrolled deepdrawing sheet based on the compact strip production CSP process a twodimensional cellular automation simulation model considering real space and time scale was established to simulate recrystallization and grain growth during the actual batch annealing process The simulation results show that pancaked grains form during recrystallization 111 advantageous texture components become the main parts of the recrystallization texture After grain growth the pancaked grains coarsen gradually The content of 111 advantageous texture components in the annealing texture increases from 55vol to 65vol meanwhile the contents of 112〈110〉 and 100〈110〉 texture components decrease by 4 and 8 respectively compared with the recrystallization texture The simulation results of microstructure and texture evolution are also consistent with the experimental ones proving the accuracy and usefulness of the model
