Problems solved by technology

[0002] In the production and processing of metal wires for shelf back nets, sometimes the alloy wires need to be processed very thin, requiring strong comprehensive performance and not easy to break; however, the existing alloy wires do not have such performance conditions, although they can meet the basic requirements. The load-bearing strength requirements of the shelf, but when storing some goods with excessive weight and uneven weight distribution, it is obvious that its comprehensive performance is not high, brittle and easy to break
[0003] The existing production process of alloy metal wire is: tube loading, electroplating, drawing, annealing, cleaning, the stainless steel fiber processed by this process, the electroplating voltage is above 10-12V, the line speed is high, and the wire is easy to break when drawing. , the pass processing rate is small, the number of annealing is large, and the chemical elements of raw materials change greatly, so the comprehensive performance can never reach the ideal level
