Production technology of preprocessing copper-clad steel wire matrix

The invention, relating to a production technology of copper-clad steel, particularly discloses a production technology of preprocessing a copper-clad steel wire matrix, successively comprising the following steps: husking, derusting with a wire brush, pickling, washing, boronizing, drawing, secondary washing, drying and spooling, and ammonia decomposition tempering. The technology has the following advantages: little pollution in the production process, complete treatment of the surface oxidation layer of the steel wire, bright surface of the steel wire, good anti-oxidation effect, and good binding force between the processed steel wire and the copper layer in the subsequent electroplating process.
