EnglishIt is mainly used for the drawing process of brass-plated NT, HT and ST strength steel cord and hydraulic hose steel wire. During drawing, it can form a stable lubricating film, effectively reducing the friction coefficient between the steel wire and the die, minimizing die wear and extending die service life. Meanwhile, it improves the surface finish of the steel wire, avoids defects such as scratches and cracks during drawing, ensures stable mechanical properties of the steel wire, and helps steel cord manufacturers reduce the defective rate caused by material flaws.
