Reference power consumption:

Iron melting: 520-610 degrees / ton fast, 750-980 degrees / ton slow

Steel melting: 550-650 degrees / ton fast, 800-1000 degrees / ton slow

Copper melting: 310-360 degrees / ton, aluminum melting: 200-260 degrees / ton

1. Fast induction melting furnace saves electricity compared to slow furnace. The same set of equipment saves electricity faster than slower. The timing of feeding and tightness, and the size of the furnace will affect the melting speed. These points must be optimized to minimize the power consumption.

2. The feeding should take into account the ammeter to make the power as stable as possible. Maximize the output of the induction melting furnace as much as possible.

3. Accurately control the temperature of the molten iron. Do not let the temperature be too high or locally too high. The high power consumption is not good for the life of the furnace lining. A good furnace worker can save electricity and be efficient.

4. Select the appropriate tonnage size induction melting furnace. Too large and too small may increase power consumption. The same large furnace saves power quickly, the same fast induction melting furnace saves power, and high voltage saves power compared to low voltage. The casting time also affects the power consumption, and it is best to control it within 5-10 minutes.

5, do not need low-grade induction melting furnace (also high price is good, after several agents distribution price is high after sale without long-term protection). The market competition is fierce. Some manufacturers cut corners and cut prices and compete at low prices. The worse the equipment, the greater the loss. If the copper bar is not directly plated, and the poorer and thinner copper material is used, the equipment seems to start to use the same, but the power consumption will become higher and higher.

6, the incoming line can not be saved, it must be large enough, otherwise the long-term loss is quite amazing.

7, develop a good boot habits, full power as much as possible and reduce heat preservation or baking time. When the power is not full, the power factor is low and the loss is large.

8. Increasing the transformer utilization rate is also equivalent to saving electricity. A 630KVA transformer should be able to melt 13-15T tons of molten iron within 10 hours. If you can only produce 10-11 tons, your average electricity price must be higher than him.

9. Scientific oven. When baking the induction melting furnace, the cooling water of the induction coil should be kept small (one-third of the normal amount of water can be used). It is best to intermittently supply water and keep the water temperature above 55 degrees to facilitate the smooth discharge of water vapor, which can shorten the time. Oven time. Some furnace workers did not pay attention to this point, and used the normal water supply. As a result, the discharged water vapor condensed into the water back to the cold copper tube, which resulted in a long and time-consuming oven with poor results.
