Abstract: A new simulator was developed to investigate continuous annealing processes and develop cold-rolled steel grades, on which the close annealing process in N2/H2 protective anmosphere is available with sheet pieces as specimens. During simulation the specimen may be tensioned with a hydraulic cylinder resistance-heated at high current and cooled by narrow-mouth nozzles for high-speed jetting/spraying, and the heating, cooling, tensioning and composition of atmosphere were all controlled according to preset parameters. The whole annealing process was implemented with no specimen moved. Describes the principle of design, system configuration, characteristics and main technical specifications of the simulator. Simulating results showed the homogeneity of micro-structure and balanced mechanical properties of the annealed specimens especially the better reproducibility of testing data.
