WORKING METHOD FOR ROLLING FINISHED PROFILES FROM A FINAL DIMENSION, FROM A PRE-PROFILE COMING FROM A CONTINUOUS CASTING DEVICE

摘要

The invention concerns a method and a roll stand configuration for production of finished sections out of a preliminary continuously cast H section with the overall dimensions close to those of the final product. The sections are produced in a reversing mode of operation in a roll stand configuration with the following groups: a) a preliminary rolling group with vertical and horizontal roll stands (VDG, HDG); b) a compact rolling group with entry and exit universal roll stands (EUG, AUG) and an upsetting intermediate roll stand (SZG); c) a finishing group with one or more horizontal duo roll stands (DHGI, DHGII, DHGIII). The preliminary rolling group has a lateral transfer system (QT) between two rolling lines (WL1, WL2) incorporating respectively exit and entry roller conveyors (RG2, RG3). Production of the locking elements and the final sizing of the sections take place in the horizontal duo roll stands.
