High Reduction Mill as a Preforming Stage in a Continuous Rod Mill.

With the further development of round casters, the high reduction mill which allows to obtain rolling passes with cross-section reductions of more than 84% in one operation, is gaining importance as a preliminary stage in wire rod mills. It can be used separately, in combination with a shaping stand and as a roughing stand in continuous wire rod or light section rolling mills and allows the rolling both of smooth wire rods and rebars. Experience gathered with an Italian wire rolling mill, on which more than 250,000 tons have been rolled up till now, show that investment and operating cost are more favorable than in the case of conventional plant.
