Manufacture of forged steel wire rope
Forged steel wire rope is twisted in the rope when the use of swaging process forging, the rope outer and inner layer of the wire deformation, the cross-section becomes: the outer rope each wire its exposed surface and the whole rope outside The tangent plane of the envelope surface becomes larger and the outer surface of each filament of some or all of the wires of the inner layer is polygonal and the tangential contact surface between the filament and the filament becomes larger and the gap between the wire and the wire becomes smaller, Forging wire rope with new features: non-rotating performance, elongation is small, not easy to deformation, resistance to extrusion, surface smooth, pass the good, wear-resistant, high density coefficient, the total breaking tension than similar products 15% Loose performance, easy to operate.
High-strength forged steel wire rope has a certain degree of difficulty in production, must be from the raw materials, heat treatment, drawing, twisting and winding of the various processes to strictly control. From the trial results, the technical data of products to similar products abroad sample requirements, but compared to the kind, the flexibility of steel wire rope there are still differences, to be further improved.
