... metals at very high speeds in a somewhat continuous manner. Because other methods of metalworking, such as forging, are relatively slow, most ingots and large blooms are rolled into billets, bars, structural shapes, rods (for drawing into wire), and rounds for making seamless tubing. Steel slabs are...
