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.
