Abstract:
A method of rolling rod comprising the steps of:(a) rolling at least a first and a second strand jointly in at least one multistrand mill stand operating at a rolling speed (v) variable as a result of predictable rolling events;(b) downstream of said multistrand mill stand separately rolling each of said strands in at least one respective single-strand mill stand;(c) forming a loop in each of said strands after the respective strand leaves said multistrand mill stand and before each strand enters the respective single-strand mill stand, each loop having a loop length (L) variable between a minimum value (L.sub.min) and a maximum value (L.sub.max); and(d) before each of said rolling events changing at least one of said loop lengths to an event-optimizing value.
