The deformation of the 6x19 pvc coated wire rope after heat treatment is generally considered to be caused by cooling, which is not true. 6x19 pvc coated wire rope, especially complex 6x19 pvc coated wire rope, the correctness of the processing technology often has a greater impact on the deformation of 6x19 pvc coated wire rope, the comparison of some 6x19 pvc coated wire rope heating process can be clearly seen The heating rate is faster and tends to produce larger deformation.
Any metal should be expanded when heated. Because the steel is heated, the temperature unevenness of each part in the same 6x19 pvc coated wire rope will inevitably cause the inconsistency of the expansion of the various parts in the mold, resulting in uneven heating. Internal stress. 6x19 pvc coated wire rope at the temperature below the phase transition point of steel, uneven heating mainly produces thermal stress, heating unevenness beyond the phase transition temperature, and also produces unequality of tissue transformation, which not only produces tissue stress. Therefore, the faster the heating rate, the greater the difference between the temperature of the surface and the core of the 6x19 pvc coated wire rope, and the greater the stress, the greater the deformation caused by the treatment of the 6x19 pvc coated wire rope.
