Hot ductility and strength of Continuous casting(CC) steels at elevated temperatures from CC processes were studied by physical simulation. The method is the hot ductility test. The design of test parameters and data interpretation are discussed. The results show that the bulging of CC steel slabs which is caused by the mechanism of creep has great influence on the formation of central segregation and internal cracks. Creep tests including static creep tests and dynamic creep ones were performed at 1200 and 1300℃. Effects of strain rate and temperature on hot ductility are also discussed and a simple model is presented to explain the interaction between hardening and softening.
