This equipment is used for online heating of trapezoidal aluminum ingots. The equipment has a rated power of 300KW, a rated frequency of 200HZ, and an online temperature increase of 80-100℃. For aluminum ingots with a cross-section of 2350 square millimeters, the hourly output is over 4 tons. Because the equipment automatically adjusts its output power, the power consumption per ton is controlled within 60 kWh . The equipment dimensions are 2400×1200×1300mm (or as per user requirements), with a total weight of approximately 2.5T and a water consumption of approximately 15 t/h. The bottom of the equipment is designed with linear guide rails, allowing for lateral movement of about 1 meter, facilitating removal when the frequency multiplier heating is not needed.
