Reel in drawing process improve the drawing force, between the drum and wire transfer is relying on the outside of the drum and the friction between wire, drum under friction wear.Drum surface contact with the steel wire, in water lubrication under dry friction condition on the surface of the steel wire drawing of high pressure, and steel wire drawing heat in great quantities, therefore, drum is a bear high temperature, high wear quick-wear part.

Drum wear directly affect the quality of steel wire surface, rapid wear leads to the increase of production cost and low production efficiency.According to the substrate material, the drum can be divided into cast iron, cast steel, low carbon steel, high carbon forged steel, medium carbon steel, etc.Different substrate material, the use of their own after surface treatment, there will be a different wear patterns.

Drum wear resistance depends on the hardness of surface coating, also depends on the strength and hardness of the substrate.The above 5 types, base shear strength of cast iron drum, anti-wear material wear and adhesive wear ability is poor.Soft substrate material of low carbon steel drum, poor ability to resist plastic deformation.The strength and hardness are higher in high carbon steel drum wear resistance significantly better, especially after surface hardening and surface coating treatment of medium carbon steel drum wear resistance is better, reel in a state of low wear for a long time.

Using supersonic flame spraying technology in drawing drum, wire drawing machine, wire drawing, wire, wire drawing cylinder, wire collecting plate, groove parts such as surface coating carbide coating, can make the surface hardness of HRC75, far more than grinding tool steel or chilled cast iron of high wear resistance;Still can make these parts matrix using ordinary steel or cast iron manufacturing, both to reduce costs, and prolong service life.
