1. The fast furnace saves electricity compared to the slow furnace. The same set of intermediate frequency furnaces is faster than slower power saving. The timing and tightness of feeding and the size of the furnace will affect the melting speed. At this point, it is necessary to achieve the best power consumption at the same time.

2 , feeding needs to take into account the ammeter, try to make the power stable. Maximize the output power of the device as much as possible.

3 , precise control of molten iron temperature, do not let the temperature too high or local too high, high power consumption, lining life is not good, a good furnace can save energy and high efficiency.

4. Select the right equipment. If the furnace is too large or too small, it may increase the power consumption. The same large furnace saves power, and the same fast medium-frequency electric furnace saves electricity. The high voltage is lower than the low voltage. Casting time also affects power consumption, preferably 5-10 minutes.

5 , do not need low-end equipment (also not high price is good, after the agent sales price is high, there is no long-term protection). The market is fiercely competitive. Some manufacturers cut corners and compete at low prices, and the worse the equipment consumption is, the greater the loss. If the copper row is not plated directly and used with a thinner copper material, the device will start to look the same, but the power consumption will be higher and higher.

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

7 , develop a good booting habit, power as much as possible and reduce the insulation or baking time. When the power is not full, the power factor is low and the loss is large.

8 , improve the utilization of the transformer is also equal to power saving. A 630KVA transformer should be able to turn 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 cooling the medium frequency furnace, the cooling water of the induction coil should be turned off (one-third of the normal water volume). It is best to intermittently supply water to keep the water temperature above 55 degrees, so as to facilitate the smooth discharge of water vapor, which can shorten the drying. Furnace time. Some furnace workers did not pay attention to this point, and the water supply was normal. As a result, the water vapor discharged from the cold copper tube condensed into water, so that the oven was long and power-consuming, and the effect was not good.

Reference power consumption:

Fused    iron: fast 520-610 degrees / ton, slow 750-980 degrees / ton

   Fused steel: fast 550-650 degrees / ton, slow 800-1000 degrees / ton

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