Description
Technical Field
The present invention relates to the field of ring travellers for textile spinning machines. More particularly, the present invention relates to a steel boronizing composition for ring traveler and a diffusion process thereof. Advantageously, the present invention improves the wear resistant ring traveler by changing the microstructure through a heat treatment process.
Background
The ring traveler is the finest and simplest mechanical element in the ring machine. It directly affects the quality of the yarns produced, since their role is to physically transform the raw materials into finished products. Therefore, the ring traveler plays a very important role in the ring spinning system. Rings and travellers have a particular influence on the yarn hairiness, among other things. The wear conditions and centering of the ring play a major role. The worn ring surface always leads to increased yarn hairiness results. Since the traveler is subjected to high mechanical and thermal stresses during the spinning operation, it remains a great challenge to improve the wear resistance of the traveler. Due to this contact, surface deformations such as scratches and diffusion deformations are unavoidable.
Accordingly, the present invention is intended to provide a steel boronizing composition for ring traveler and diffusion process for improving wear resistance of ring traveler by changing microstructure through heat treatment process.
