Abstract
A method of rolling rod in which at least first and second strands are jointly rolled in a mill line having at least one final multistrand stand operating at a rolling speed which is variable as a result of predictable rolling events. Downstream of this stand the strands are separated and passed through single-strand mill stands and loops are provided upstream of the first single-strand mill stand in each line. Each loop has a loop length which can vary between a minimum and a maximum value. Before each of the rolling events occur at least one of the loop lengths is changed to an event optimizing value.
Claims11
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.
