Wire drawing industry

Solution:

The supersonic flame spraying process is used to spray carbide ceramic coating on the surfaces of parts such as wire drawing tower wheels, wire drawing machines, wire drawing wheels, wire pulling cylinders, wire pulling plates, guide grooves, etc., which can make the surface hardness reach HRC75, which is far higher than that of mold steel or cold hard cast iron; the substrate of these parts can also be made of ordinary steel or cast iron, which not only reduces costs but also extends the service life.

The pulling force is increased during the pulling process. The force transmission between the roll and the steel wire is carried out by friction between the outside of the roll and the steel wire, which is subject to friction and causes wear. When the surface of the reel comes into contact with the steel wire, it is subjected to the high pressure on the surface of the wire drawing and the large amount of pulling heat brought by the steel wire in a dry friction state that is lack of water and lubricated. Therefore, the reel is a vulnerable part that withstands high temperature and wear.

The surface wear of the reel directly affects the quality of the steel wire, and excessive wear leads to an increase in production costs and a decrease in production efficiency. According to the matrix material, the reel can be divided into cast iron, cast steel, low carbon steel, medium-high carbon forged steel, medium-carbon steel, etc.
