Why is the surface of the wire drawn by the drawing machine oxidized?
- Feb 09, 2018 -

In industry, wire drawing machine is a commonly used for drawing wire equipment, but in the process of drawing, often happen some problems, for example, we found that the use of wire drawing machine to pull out of the surface of the metal wire can produce different degree of oxidation, this is what reason is caused?

As we know, wire drawing machine usually belongs to continuous operation, the reason will be pulled out of the surface of the metal wire to produce different degree of oxidation of this kind of situation, probably there are three reasons, the concrete content is as follows:

In the first case, it is possible that the cooling water temperature in the sealed chamber does not meet the requirements, thus achieving the desired cooling effect. Such as cooling water temperature is very high, even more than 40 ℃, therefore, despite the cooling process but have not reached the standard of cooling, lead to pull wire drawing machine of monofilament still has high temperature after annealing, in this case oxygen in the air, thereby oxidizing phenomenon.

The second case, the inside of the chamber may be due to the sealed cooling fluid composition appeared problems, such as not enough saponification liquid, this kind of situation, will cause the wire drawing machine to pull out the friction between the wire and the idler pulley, as a result, and can make the wire temperature rises, the surface oxidation of the metal wire.

The third case, may be due to the sealed interior of the cooling water pressure is insufficient or too little water, this situation will lead to poor cooling effect, so you can't have good cooling effect, finally and pull wire drawing machine wire oxidation.

For such a problem, we suggest that the measures should be taken: 1. Check whether the equipment for cooling circulating water is functioning properly and whether the cooling effect is normal; 2. Every once in a while, a certain amount of material can be put into the sealed chamber to increase the concentration of saponifying liquid, thus ensuring that the wire can operate normally on the guide wheel; 3. Pay attention to the normal water pressure of circulating water, and adjust the pressure and water amount of cooling water in the sealed chamber according to the water pressure.

In the process of using the wire drawing machine, it is possible to solve the problem of oxidation of the wire in accordance with the above measures.
