PURPOSE: To provide guide shoes with guidability equal to the guidability of stationary type guide shoes and to permit rapid replacement of guide shoes by fixing respectively one piece among the plural guide shoes on a pair of base bodies in parallel to a rolling line and moving the positions of the base bodies in a direction perpendicufar to the rolling line or fixing the positions.
CONSTITUTION: The guide shoes 2 are mounted at respective sides of hexagonal rotary disks 1. The sides of the rotary disks 1 of the guide shoes 2 and the corresponding side faces of the rotary disks 1 are attached with ruggedness in the longitudinal direction of the guide shoes 2 to prevent the guide shoes 2 from moving in a direction perpendicular to the hexagonal surfaces of the rotary disks. The reverse sides of the guide shoes 2 are guide surfaces, which restrain a billet or steel pipe by coming into contact therewith at the time of rolling. The rotary disks 1 are rotatable by revolving shafts 5. The rotary disks 1 are rotated to bring another guide surface in parallel with the rolling line when one guide surface wears. Pins 6 are then inserted into pin holes 6 to fix the rotary disks 1.
