Abstract
A method and apparatus for finish rolling long products such as bars, rods and the like, comprising: in a first operational mode, rolling the products through a finishing block and a reducing sizing mill arranged on a primary pass line; and in a second operational mode, diverting the products from the primary pass line to a secondary pass line bypassing the finishing block and then back to the primary pass line for rolling in the reducing sizing mill. Optionally and preferably, a cooling unit is shifted between the primary and secondary pass lines to cool products being rolled in each operational mode.
Claims5
A rolling mill finishing section for rolling long products such as bars and rods, comprising:
- a finishing block and a reducing sizing mill arranged sequentially along a primary pass line;
- a secondary pass line departing from said primary pass line at an upstream junction preceding said finishing block, said secondary pass line bypassing said finishing block to rejoin said primary pass line at a downstream junction preceding said reducing sizing mill;
- switch mechanisms at said junctions, said switch mechanisms being operable in a first mode to direct products along said primary pass line for rolling in both said finishing block and said reducing sizing mill, and being operable in a second mode to direct products initially along said secondary pass line to bypass said finishing block and then to return said products to said primary pass line for rolling in said reducing sizing mill;
- and
- a water cooling unit located between said upstream and downstream junctions, and means for shifting said water cooling unit between said primary and secondary pass lines to cool products being rolled in each of said modes.

- in a second operational mode, diverting said products from said primary pass line to a secondary pass line bypassing said finishing block and then back to said primary pass line for rolling in said reducing sizing mill;
- and
- shifting a water cooling unit between said primary and secondary pass lines to cool products being rolled in each of said operational modes.
