Synopsis : A continuous forging process invented by Kawasaki Steel is capable of producing rods and bars with no center segregation. This process is employed in a continuous forging machine that is used with the No. 3 continuous bloom caster at Mizushima Works. The method also makes it possible to control the chemical composition in the central region of continuously cast blooms, and has resulted in a noticeable improvement in the drawability of high-carbon steel rods and in the ease of drilling in the central region of carbon steel for machine structural use. By eliminating the segregation problem, this method makes it possible to increase the super-heat at the tundish and thus reduce the number of nonmetallic inclusions; improved rolling-contact fatigue life has consequently been obtained for bearing steel. |
