How adaptable is the induction heating power supply to continuous automated production?

The rapid heat treatment of steel pipes, steel rods and steel wires all adopts continuous heating production methods. Induction heating power supply must adapt to the following working conditions.

(1) The output power of the power supply remains stable under long-term continuous conditions. The induction heating power supply is required to have good working stability and reliability to ensure the continuous and stable operation of the production line. In this regard, the parallel inverter power supply is due to the series inverter power supply.

(2) The power capacity of a single induction annealing power supply is large. Large steel pipe quenching and tempering production lines need to be equipped with high-power heating inductors, and the power of each inductor can reach hundreds of kilowatts. Therefore, it is required to provide high-power variable frequency power supply for easy configuration and management. In this case, the parallel inverter power supply has superior conditions and can provide high-power variable frequency power, but the series inverter power supply is not competent.

(3) The output power of the induction annealing power supply should have a large control range. Large-scale steel induction heating rapid heat treatment production lines cover a wide range of steel specifications and sizes, and the heat treatment temperature range is large. The output power of the variable frequency power supply is required to be able to produce within a wide range. In this case, only parallel inverters can be used The power supply can better adapt to the requirements.

In summary, the selection of power supply type for induction annealing rapid heat treatment of steel is an important and comprehensive technical task. His choice depends on product type, output size, heat treatment process type and other conditions. The selection process should be based on experiments to verify the effectiveness of the treatment and then determine the type of power supply. At present, domestic induction heating manufacturers can supply various types of power supplies for users to choose from. Through joint cooperation between both parties, a reasonable heating power source will be selected.
