Problems solved by technology

[0002] In the production process of steel wire, especially in the production process of medium and high carbon steel wire, in order to ensure the normal progress of the drawing process and achieve the required final performance, lead quenching treatment is widely used for intermediate heat treatment at present, in order to obtain high Comprehensive mechanical properties and drawing properties, but due to the pollution of lead vapor and lead dust to the environment and the harm to the human body, with the enhancement of human environmental protection awareness, it is necessary to find an economical, clean and safe heat treatment method to replace lead quenching. It has become a very concerned and urgent problem in the field of metal products. Water bath treatment is an effective method to replace lead quenching and completely eradicate lead pollution. However, the strength of steel wire after traditional water bath treatment is lower than that of lead quenched steel wire. Without effective treatment before and after use, the process efficiency is reduced

Abstract

The invention relates to the technical field of steel wire processing, and discloses a production quenching process of a steel wire. The production quenching process comprises the following steps of unwinding: conveying the steel wire to a winding device at certain speed by virtue of a steel wire unwinding and winding device; heating: performing muffle heating or electric heating on the moving steel wire, wherein the heating temperature is between 850 to 1000 DEG C, and the steel wire is austenitized; drawing: performing roller die drawing on the austenitized steel wire, wherein the amount ofdrawing compression is controlled between 20% and 40%; and performing water bath treatment: performing water bath treatment on the drawn steel wire. According to the production quenching process of the steel wire, the borax cycle temperature and concentration are uniform, borax is saved, and the drawing is facilitated; the boron binding force is increased; the color of the steel wire and the surface boron quality are changed by drying, and the steel wire is conveniently stored and drawn after being wound; and the pickling concentration is high, the acid consumption is high, and the pickling effect is greatly increased by increasing the temperature.
