ABSTRACT:
A process and apparatus for the continuous shearing of billets or bars of various shapes and sizes produced in a continuous casting plant wherein the shearing device moves in harmony with the billets is described. According to the process and as permitted by the apparatus, a first blade preferably the upper blade is caused to approach a billet and rest on it by means of hydraulic pressure working on cylinder/piston means, and thereafter a second blade positioned opposite the first blade is caused to move from supporting brackets to approach the billet and thereafter the blade caused to continue its course and cut into and shear the billet with the shears being supported substantially only by the billet during the shearing process. The device is relatively simple in design and is highly efficient.
