The blast furnace double car hoist feeding control system using D32 inverter has been put into operation for more than three years, and has achieved good economic and social benefits

• The control device operates reliably, has good environmental adaptability, can resist harsh environments such as oil pollution, dust and damp heat, and has a low failure rate;

• Realize the smooth lifting and speed change of the feeder, and avoid the phenomenon of large start-up vibration, easy slippage and trailer phenomenon of the traditional winch system;

• Excellent current limiting characteristics, strong overload capacity, can effectively reduce frequency conversion overload, overcurrent protection, and maximize production continuity.
