  • Patent number: 4883111
    Abstract: The mould includes wide side plates 4, 5 and adjustable narrow side plates 2, 3 which can be clamped by the wide side plates 4, 5. Adjusting cylinders 11 operable by a hydraulic pressure medium are used to adjust and tension the wide side plate 5. To prevent the tensioning from becoming accidentally loosened if the pressure medium fails, the wide side plate 5 is additionally supported, more particularly on clamping elements 12 which can be clamped to the piston rods 13 of the adjusting cylinders 11. A control device 21 activates the clamping elements 12 when a limit pressure is reached at the adjusting cylinders 11.

  • Patent number: 4336078
    Abstract: A process and apparatus for separating metallurgical products such as ingots, slabs or plate-shaped workpieces using a cutting torch disposed on one side of the product which follows a prescribed cutting line and which forms a front cutting edge on the surface of the product facing the torch and a rear cutting edge on the opposite side of the product and a cutting joint therebetween. At least one gaseous jet is directed at the rear cutting edge of the product to blow molten metal and liquid slag formed during cutting away from the rear cutting edge, thereby preventing the formation of flame burrs at the edges of the cutting joint.
