The role of wire drawing lubricant

Wire Drawing lubricant, consider from the macroscopic process, can be summarized that the function of lubricant is good between wire and die hole, establish an ideal lubricating film isolation layer, which can make the metal plastic deformation has become easier, but also can reduce the friction coefficient, reduce energy consumption, good friction heat to control the drawing, drawing to ensure the normal and ensure the stability of product quality. In the process of drawing "drawing fever" of normal production drawing great harm. Therefore, the function of lubricant in theory can be summarized as follows: to prevent the drawing temperature. From the specific lubricant its role has two: prevent the adhesion of wire and die wall drawing, reduce the friction coefficient and prevent adhesion is very important. As long as the realization of the two objective, can inhibit drawing fever. So, this is from the requirement of lubricant A point of view. In addition, in the actual production, the lubricant quality assessment and drawing die life forever inseparable. Therefore, the quality of the mold itself. Even if the lubricant must ensure excellent, and the bad die hole, angle is not good, also can make the lubricant is poured out, cannot build good lubricating film on the metal surface. Especially in the high-speed wire drawing, in addition to the lubricant compressive capacity increase, mold quality factor is also very important. In short, in the study of the function of lubricant, the lubricant requirements at the same time, will be the inner link and die.
