Abstract

The testing facility used for simulation procedures of the thermomechanical history of continuously cast slabs before the straightening operation is described. The tests were made on in situ solidified specimens to reproduce the continuously cast microstructure and to follow the temperature history of the continuous casting process. The basic principle and procedure of the test are explained. The hot ductility curves and microstructures obtained are discussed for the approximate temperature range 700 to 1100 °C. Results are compared with one another and with other tensile test data.
