4. Improved Billet Shape Modeling in Optimization of the Hot Rod and Wire Rolling Process
University essay from Institutionen för systemteknikAbstract : The hot rod and wire rolling process is widely used to produce rolled iron alloys in different shapes and dimensions. This industry has been under a constant development during the last decades. Today, complex geometries are produced at a high speed since it is possible to use several stands in each mill at the same time. READ MORE
