ABSTRACT This invention relates to a method of and apparatus for the positioning of thick slabs to be introduced into a furnace, particularly into a walking-beam furnace, said positioning being effected with the aid of optical means and electronic means . By this method, at each lateral region opposite the furnace mouth , onto the upper surface of a slab and at the region of its end faces , there are projected at least two blades of light of a given length, which are normal to the direction of entrance and advance into the furnace and parallel to each other, the ends of which are perfectly aligned on a straight line which is parallel to the direction of entrance and advance into the furnace, said blades producing parallel lines of light on said surface of the slab , said lines being interrupted at the end edges of said slab. The deceleration of the slab transporting movement, and the stoppage thereof, is determined with the aid of electronic means as a function of the length of said lines of light .
