The line is mainly used for copper wire drawing and continuous annealing. φ450 the drum wheel surface spray coating tungsten carbide, degree of hardness is high, the resistance to wear is good, the service life is long. The back guy main engine and the constant speed turn splitting independent motor-driven, has trades the mold function fast. The double plate continual recover of wire, trades the plate automatically, quaranteed trades the end of a thread the annealing quality. Uses the direct current mahine to actuate, the starting movement is steady. The electrical control, selects the import the driver and plc, the function is complete, the performance is stable.
