ABSTRACT:
In the rolling of wire or rod in a rolling line having a roughing or intermediate block whose rolling stands have non-adjustable rolls except for those at the exit end of the block, the rolls of the non-adjustable stands can be re-used at least once in the same stand location after being re-conditioned by reconditioning all the rolls defining a first series of sizing passes so as to form a second series of sizing passes whose individual sizes are larger than those of the first series. The change in dimensions of a given sizing pass as a result of reconditioning is less than the difference between the dimensions of that sizing pass after reconditioning (i.e. of the second series ) and the dimensions of the immediately preceding sizing pass before reconditioning (i.e. of the first series). Thus, after a second or subsequent reconditioning the rolls of a given stand are transferred to the immediately preceding stand for re-use to define the first series of sizing passes.
In this way, the amount of roll material removed at each reconditioning operation is reduced.
