UNIVERSAL HEAVY-TYPE RAIL-PASS DESIGN

An attempt to introduce two new sections at the Nizhnii-Tagil Combine on the rail and structural mill is described, viz, heavy R-75 rails and OR-75 ramp rails in small roll-change batches between the normal R-65 rails. Due to the universal nature of the T-Shaped passes in the roughing stands it was found possible to do so to a large extent using the same rolls as used for the R-65 rails. A formula was deduced for calculating the width of the finishing pass which allows for the deformation of the section during subsequent cold straightening in the roller straightening machines. Roll-pass designs, reduction sequences, and methods of mounting the passes in the rolls are presented for rolling these R-75 and OR-75 rails.
