Abstract
PURPOSE:To make possible the single installation of feed various kinds of raw materials, by catching the steel material transmitted onto the elevating table on the entry side with multiple vertical roller groups movable to the side of the entry table. CONSTITUTION:When the pierced raw material W is transported on the roller table 39 is the arrowed direction F and stops in front of the pusher 40, and the pusher 40 is moved in the direction perpendicular to the roller table 39, and the pierced raw material W on the table 39 slips on the skid 41 and falls down onto the entry table 19, and is placed on the horizontal roller 21 of the entry table 19. Next, the hydraulic cylinder 35 is actuated, and the lever 31 is turned around the pin 30 through the tie-rod 33; hereby, the both side planes of the pierced raw material W on the entry table 19 are caught by multiple vertical rolls 32. Then, the pierced raw material W is pushed into the gap of the reducing rolls 18A of the piercing mill 18 by the pusher 42.
