The rotating mold box is the slow rotation of the mold itself when the wire is drawn, and the lubricating powder is forced into the mold in a spiral manner, which increases the effect of powdering, prolongs the service life of the mold, and reduces the friction coefficient between the mold and the steel wire. Electricity is about 5%. At the same time, it avoids the wear of the fixed point of the mold due to the defects of the steel wire, and saves more than 10% of the mold. The steel wire has good roundness. At the entrance of the die, the lubricating powder that is melted or carbonized at high temperature rotates and is diluted or extruded. New lubricating powder enters the die continuously, and the yield of steel wire is increased by more than 20%.
