ABSTRACT:
A high-speed rod and wire mill, particularly for single-strand, twist-free rolling. The mill includes a roughing train, at least one intermediate train and a subsequent finishing train, wherein each of the trains includes several rolling mill stands or rolling units. A finishing stand set may follow the finishing train. For a minimized series of passes in each train section, the roughing train has a crane tool for exchanging the rolls, the intermediate train has a manipulator for exchanging the rolls and the finishing train has a quick-exchange device for changing the rolls and possibly an additional manipulator. All rolling mill stands or rolling units in the individual train sections have overhung-mounted and removable rolls, so that the yield of the mill is increased.
