1. Press control: Metallurgical presses need to control power signals to achieve automated production. With the use of frequency converters, the operation of the press can be controlled by adjusting the frequency and voltage of the power signal, thereby achieving intelligent automatic control.

 2. Fan control: In the metallurgical industry, a large number of fans are needed to ventilate and cool molten iron and smelting furnaces. The frequency converter can be used to control the speed of the fan, thereby adjusting the air volume to adapt to different production conditions and save energy. reduce manufacturing cost.

 3. Conveyor belt control: Conveyor belts are needed to transport materials on production lines in the metallurgical industry, and the speed of the conveyor belts also needs to be controlled. The frequency converter can be used to accurately control the speed of the conveyor belt, thereby ensuring the smooth progress of the production process.
