Why is there oxidation phenomenon in the single wire pulled out by the wire drawing machine?

1. The temperature of the cooling water in the sealing chamber is too high, exceeding 40 ℃, which results in the inability of the sealing chamber to achieve the required cooling effect on the single wire, resulting in the single wire still having a high temperature after annealing and oxidizing when encountering oxygen in the air at high temperatures.

2. If the saponification liquid content of the coolant in the sealed chamber is insufficient, it will increase the friction force between the monofilament and each guide wheel, which in turn will cause the temperature of the monofilament to rise again, causing surface oxidation of the monofilament.

3. The water pressure and quantity of cooling water in the sealed chamber are insufficient, making it impossible for the single wire to achieve satisfactory cooling effect.

Solution:

Frequently check whether the equipment for cooling circulating water operates normally and whether the cooling effect is normal;

Add substances that can increase the concentration of saponification solution in the sealed chamber at regular intervals, which can change the content of saponification solution in the cooling water and ensure that the monofilament can operate normally on the guide wheel;

Regularly check whether the water pressure of circulating water is normal, and constantly change the pressure and water volume of cooling water entering the sealing chamber according to the change of water pressure during production.
