A METHOD TO PRODUCE HIGH FREQUENCY STOP-AND-GO MOVEMENT IN CONTINUOUS CASTING, ESPECIALLY OF WIRE RODS

摘要

A method to create high amplitude stop-and-go strokes in continuous casting of small cross section products, especially wire like. The method is based on swinging the cast wire itself on both sides to generate the movement at the solidifying down end of the wire. The drawing rolls operate simultaneously with steady (adjustable) speed. The swinging of the wire is generated between the upper end of the diecooler and the drawing rolls with e.g. a runner which is connected to an eccentric disk rotated by an electric motor. The amplitude and the frequency of the swinging and the speed of the drawing rolls can be varied and so achieve different movement forms in casting.
