Description

Technical Field

[0001] The present invention relates to the field of aluminum-clad steel wire production, and more particularly to a drawing system for aluminum-clad steel wire. Background Art

[0002] The mainstream bimetallic synchronous drawing process for aluminum-clad steel wire products uses a dry powder drawing method. This method uses a tungsten steel mold to form a pressure zone and a necking zone. The product is synchronously deformed by applying sufficient axial traction. The high temperature generated by the mold during the deformation process is continuously cooled by circulating water to prevent the mold from being subjected to sustained high temperatures and increased wear, which can reduce its service life. However, through continuous production experience, it has been found that the dry powder drawing method has the following disadvantages: dust emissions have a negative impact on the atmosphere, and long-term exposure to dust during production operations can easily cause respiratory diseases, posing an occupational hazard. The use of water cooling in dry powder drawing makes it difficult to control the temperature drop rate. Rapid temperature drops in cold seasons pose an adverse quenching risk to the use of tungsten steel metal molds, and repeated use of the mold over a long period of time can easily cause the mold to explode. Water cooling is corrosive to tungsten steel metal molds, and replaced molds require re-surface rust removal before they can be reused, reducing the mold's service life. The water vapor environment generated under high temperature conditions poses a corrosion risk to various equipment parts. Summary of the Invention
