There are many conditions for selecting a pull lubricant, and sometimes it is constantly changing. Therefore, you can refer to the drawing conditions described earlier. Some of these contents have already been discussed. Here we mainly describe the drawing speed and cooling effect.
High speed drawing lubricant
Lubricant adaptability of up to 1000m / min above the drawing speed can usually be called high-speed drawing. We must use a lubricant that is added with extreme pressure additives or solid MoS2 additives. At the same time, should also be based on drawing different specifications, pay attention to the adjustment of the particle size of the lubricant in order to achieve the purpose of drawing.
2. Cooling effect
The cooling process in the drawing process is very important and is an important part of ensuring smooth drawing. Cooling effect can be considered from two aspects, one is the outside of the car plate, mold, wire cooling; the other is the lubricant itself can have the cooling effect.
External cooling factors will affect the choice of softening point of the lubricant. When the use of pulley line drawing machine, live sets of drawing machine drawing, the wire cooling effect than the use of diameter wire drawing machine is better. Each pass of the drawing heat is not easy to accumulate, to keep each pass into the line temperature is not high. In the high-speed drawing, if the softening point of the lubricant is slightly lower, but also to adapt to pull.
