Abstract (en)

A measurement system (1) for measuring the position of the axes of the rollers of a containment and guide segment, adapted to contain and guide a cast product exiting from a crystallizer in a continuous casting process, the system comprising a robot (2) having an arm (4) provided at one end thereof with a reflector (5), said robot being adapted to move the reflector (5) in order to successively put it in contact with a plurality of points of each roller of the containment and guide segment; and comprising a laser tracker (3) adapted to track the reflector (5) by means of a laser beam and to calculate the position in space of each of said points of the containment and guide segment so as to determine the position of the axis of each roller.
