Forging Process:
The overall die drawing method,the round strands are subjected to radial extrusion under the die wall during drawing, and are drawn and compressed into a fan-shaped section strand. While the wire rope adopts the interactive twist method, the lay length of the rope is increased and the twist of the strand is reduced. To balance the twisting moment of the rope with the total twisting moment of the strands, so as to achieve the non-rotation of the wire rope.
