Elongation factor of steel wire rope
There are many factors that will lead to the elongation of steel wire rope in use, and some factors lead to very small elongation, which can be ignored. Generally, the main causes of wire rope elongation are as follows, of which the first two are Important factors.
·Structural elongation: the elongation caused by the steel wire in each share and the position adjustment page of each strand in the steel wire rope; The length of the part caused by the free rotation of one end of the steel wire rope and the increase of the twist distance; Further elongation caused by the reduction of the metal area of the steel wire rope due to the wear of the internal steel wire. The above elongation is collectively referred to as structural elongation.
·Elastic elongation: elongation within the elastic range of a material due to tensile load.
·Plastic elongation: caused by a load exceeding the yield point of a material Sexual, inelastic elongation.
·Temperature: elongation or shortening caused by temperature change.
