Abstract (en)
[origin: EP0014655A1] 1. A method of manufacturing crushing bodies from a ferrous alloy containing at least 1 % by weight of carbon, with axial symmetry or constant section, this method comprising shaping of the crushing bodies and a thermal treatment, the shaping comprising a solidification operation in an open ingot mould of a shaped section coming from continuous casting of said alloy, followed by division of said shaped section into billets and the thermal treatment being adapted to confer on the metal an austenitic or martensitic structure, this method being characterized in that the operation for dividing the shaped section into billets constitutes the final shaping operation of the crushing bodies to the exclusion of any plastic deformation thereof, so as to preserve for said bodies the radial crystallization structure resulting directly from the continuous casting of the shaped section.
