Function Structure

Cold rolled ribbed steel bar annealing production line is complete automatic control: two sets of medium frequency power supply accomplish annealing of ribbed steel bar online. Realize synchronization control of production line by several sets of inverters driving the mechanism.

There are totally two sets of heating power supply of cold rolled ribbed steel bar annealing production line, the power and frequency of which are designed to be: 500kW/8kHz,100kW/8kHz. The power supply adopts parallel IGBT induction heating power supply. It is just because of online heating that there’re strict requirements concerning working status and synchronization control of the power supply.
