Abstract

Process of heat treatment of rails to improve their properties, characterized in that it consists in submerging the still hot rail that leaves the rolling mill in a coolant maintained at a constant temperature, so that the steel undergoes complete isothermal, pearlitic, or preferably bainitic transformation.
