PURPOSE:To shorten the time for switching a line and to improve productivity by arranging the table rollers before and behind a rolling roll like steps and making the level of each table roller into a prescribed curvature in rolling a steel bar or wire with rolling rolls with a caliber. CONSTITUTION:When the rolling line is switched, even if the difference of elavation is generated between the level of the lower roll 1B of upper and lower rolling rolls 1A, 1B with the caliber 1a and the level of pass lines P, L, the bar/wire W is made to reach the level of pass line, because the bar/wire which is passed through on the table rollers 3 after completing rolling is bent into the curve with the prescribed curvature R with these table rollers 3. Therefore, it becomes unnecessary to change the level at the time of switching the rolling line. |
