摘要
Austenitic steel shot at above 720 DEG C is fed into a fluidised bed of steel shot in a first container (20). Fluidising coolant air is passed through the bed to quench the steel shot to a temperature in the range of 250 DEG C to 450 DEG C. The quenched shot is fed to a static bed in a second container (12) where it is held at a temperature in the range of 250 DEG C to 450 DEG C for a length of time sufficient for it to develop a substantially bainitic structure.
