The paper explores in depth a new annealing technology -electric pulse annealing treatment. To improve the disadvantage of the traditional annealing, such as, low efficiency, high energy consuming, polluting the environment, badly oxidation of the product surface, and so on, a new technique that carrying through the annealing and soften treatment with pulse electric current on the Q235 steels was put forward in the text. The experimental device was designed and the parameter was optimized in this assay. And also, the annealing mechanism was explored according to the analyzing of the metallurgical structure and the changing of the property of the steel wires. It is found through the analysis that the pull-out resistance of the wire is significantly decreased and the elongation is improved significantly after electric pulse treatment, and the effect of using high-strength pulse current treatment about 25 seconds (temperature up to 390°C) is similar to the effect with traditional annealing or even reduce the initial temperature.
