LE GUIDE, DESTINE A SUPPORTER LES COTES DES BARRES D'ACIER SOUMISES A UN LAMINAGE PAR DES CYLINDRES NON CANNELES, COMPREND DES CHASSIS AVANT ET ARRIERE 1, 1 DE GUIDAGE DE LAMINAGE, COMBINES AFIN QU'ILS SOIENT EN BUTEE L'UN CONTRE L'AUTRE DANS UNE EMPRISE FORMEE ENTRE DEUX CYLINDRES AYANT DES CORPS CYLINDRIQUES, LES CHASSIS ETANT DESTINES A ENTOURER LES DEUX CYLINDRES VERS L'AVANT ET VERS L'ARRIERE AFIN QU'ILS FORMENT DES ZONES DELIMITEES DE LAMINAGE DISPOSEES COTE A COTE DANS LA DIRECTION AXIALE DES CYLINDRES ET SEPAREES PAR LES CHASSIS DE GUIDAGE DE LAMINAGE. A method of rolling steel rods or wires by grooveless rolls involves limiting to less than 1.5 the ratio of a long side to a short side of a rectangular cross-section blank material which has passed through each pair of grooveless rolls, or limiting the ratio of a diameter of each pair of grooveless rolls to a gap therebetween. A guide for rolling steel rods for supporting sides thereof comprises front and rear rolling guide frames consisting of partitions abuttingly connected to each other in a gap between a pair of rolls having cylindrical surface barrels to form defined rolling zones which are side by side along the roll barrels and divided by the partitions and capable of retaining steel rods being rolled, thereby effectively carrying out rolling of steel rods with grooveless rolls without twisting and deforming the steel rods into incorrect cross-sections.
