摘要:
A method for removing burr in a continuous rolling process of the first aspect of the present invention comprises the steps of: joining the rear end of a preceding billet (10) with the front end of a succeeding billet (10) using the flash butt welding method while running both thereof; and grinding a burr on the welded part of the joined portion using a plurality of grinders (31) while the billets running and while rotating the grinders and moving thereof synchronously with the travelling speed of the billets. and A grinding machine for continuously rolling a round billet (20) comprises: a travelling body (11) shuttling along the direction of the round billet movement; a turret ring (55) supported by the travelling body in a rotatable state thereof; a plurality of grinding devices (51) arranged in a movable manner within a radius of the turret ring; and grinders (31) of the grinding device, which are set at a tilted angle against the center axis of the turret ring.
