Abstract
Heavy profiled supports or rails may be produced by rolling through a series of rolling stands. Material is passed through a two-high reversing pre-rolling stand, an edging stand, a reversing universal stand, a second compression stand, and a second reversing universal stand. When rails are to be produced the material is passed through stands in through-travel only. When rolling profiled supports it is preferable to replace the stand by a roller train section.
Claims3
A rolling mill train comprising two two-high reversing rolling stands;
