在对进口的钢丝绳的检验中需要对在三维空间扭曲的钢丝绳试样进行矫直。这种矫直过程中不允许钢丝表面出现任何缺陷(砂孔、凹坑、裂纹),不允许钢丝截面发生变形,或因加工硬化而使其抗拉强度及扭转性能发生变化。如西德DIN51200/1960的金属材料试验一节中规定:如果需要可以将试样矫直。为了“矫直”,必须选用下列各种方法之一或根据协议进行。
Straightening of wire rope samples that are distorted in three-dimensional space is required in the examination of imported wire ropes. This straightening process does not allow any defects on the surface of the wire (sand holes, pits, cracks), does not allow deformation of the wire cross section, or due to work hardening and tensile strength and torsional properties change. For example, in the metal material test section of West Germany DIN51200 / 1960, the sample can be straightened if necessary. In order to “straighten”, you must choose one of the following methods or according to the agreement.
