Abstract
The invention provides a preparation process of a tungsten wire rope special for a crystal growth device. A twisting mechanism of the tungsten wire rope adopts an epicyclic gear train to enable each tungsten wire to inversely revolve on axis per se for a circle with respect to a twisting center while the twisted tungsten wire rope is twisted for a circle, so that the twisted tungsten wires are wound mutually and tightly without loosing easily. Due to twisting of multiple strands of basic threads, the wire threads in the center, the twisting of an inner layer and the twisting of an outer layer can be finished for once; or the twisting of the multiple layers of the finished tungsten wire ropes (ropes) can be finished for once in a manner of two layers. The preparation process of the tungsten wire rope, disclosed by the invention, removes inner stress generated after the twisting of the tungsten wires and simplifies the technical process.
