The grease content of copper wire drawing fluid can not be ignored for the lubricating performance of wire drawing
April 25, 2022
The fat content of the copper wire drawing solution can be simply understood as the thickness of the oil film formed in the deformation zone during the copper wire drawing process. Too high or too low the fat content of the copper wire drawing solution will affect the thickness of the oil film formed in the deformation zone during the copper wire drawing process. Although the drawing temperature and the viscosity used are also the main factors affecting the lubricity of copper wire drawing, the adverse reaction caused by the oil film thickness caused by the grease content cannot be ignored.
The common oil film thickness is too thick, the following situations will occur: 1. The oil film is too thick, and the pulled copper wire loses its surface gloss 2. The copper wire drawing process causes local unevenness and incompleteness of the oil film in the deformation area, resulting in an increase in the direct contact area, increased friction and oil spots on the surface of the drawn wire product. 3. If the fat content of copper wire drawing is too high, a part of it will be freed, causing the emulsion to be layered and adhered to the copper powder, suspended on the emulsion, sticking to the mold hole, causing blockage of the mold hole, and then breaking the wire. In severe cases, it will even directly lead to the deterioration of the lubricating oil, requiring the entire pool to be replaced, resulting in losses. If the fat content of the copper drawing fluid is too low, the oil film must be very thin, or a complete oil film cannot be formed. In the process of wire drawing, it is easy to cause cracks, so that the drawn copper wire and the die cannot be lubricated, and the friction force is increased, which will cause the following undesirable conditions: 1. The tensile force increases, which will lead to frequent disconnection 2. Friction increases, heat is generated, oil temperature rises, and fuel consumption increases 3. The surface quality of the drawn wire is reduced 4. The mold and the tower wheel wear quickly, and the copper powder increases Water-based copper wire drawing fluid is suitable for drawing and lubricating copper wire, and it is a powerful tool for wire drawing factories to improve the quality. Product Features: 1. The emulsification system is perfect, the water quality requirements are not high, and the emulsification stability of the copper wire drawing liquid will not be destroyed at the boiling temperature, so the wire drawing liquid is not easy to age. 2. It is suitable for high-speed wire drawing. It can be used at high speed for a long time at a top speed of 2500 m/min to 2800 m/min. 3. Strong rust resistance, special rust resistance, can make the copper after drawing maintain a bright surface for a long time.
