  • For single-layer wound non-rotating wire rope, it is necessary to strictly abide by the above principles, otherwise it is easy to cause permanent deformation of wire rope structure; In the case of multilayer winding, the rotation of the rope is determined by the orientation of the reel’s rope groove to lay the foundation for the next layer. The friction between the wire rope and the extrusion pressure of the multi-layer winding drum are large, and the disorderly rope phenomenon is easy to occur. Therefore, the wire rope with a diameter slightly smaller than the pitch of the rope groove and the diameter of the rope groove should be selected to add the touch area between the wire rope and the drum.

  • Deoxygenation of boiling steel is incomplete, oxygen content is high, phosphorus and other impurities distribution is uneven, local overspending, aging sensitivity and cold brittle sensitivity are high, hot cracking tendency is added. If unqualified electrode is used, if the content of carbon and sulfur in the weld metal is too high, cracks will occur. For example, when factories use acidic electrodes to weld Q235-A steel, the high carbon fernoganese in the electrode coating will lead to thermal cracks in the weld.

  • The tensile strength of steel wire is high and the hardness is high. In the flattening process, the longitudinal movement resistance of steel wire per unit volume increases and the elongation decreases. The steel wire unit volume will move to the lateral resistance smaller, the width of the increase. On the contrary, the wire is easy to extend lengthwise, and its width decreases. This is the production of high steel wire hardness is easy to wide, small hardness, easy to stretch out of wide reasons. If the tensile strength deviation of steel wire is large, the hardness uniformity of steel wire strip is poor, the width difference of the billet rolled into large, will seriously affect the quality of the billet.

  • High quality galvanized wire in general, the zinc layer attached to the surface of the wire is relatively thick, so when we buy galvanized wire, as long as we look at the thickness of the zinc layer machine, we can generally judge whether the quality of galvanized wire is high quality.
