Nine methods for smelting power saving in induction melting furnace

1. In general, induction melting furnaces save electricity than slow furnaces. The same set of equipment is faster than slow power saving, while paying attention to the timing and tightness of feeding, the size of the furnace, etc., all of which meet the best power consumption at the same time.

2, induction melting furnace feeding needs to take into account the current meter, try to make the power stable, as much as possible to make the IF power supply equipment output the maximum power.

3. Remember to accurately control the temperature of the molten iron. Do not let the temperature of the electric furnace be too high or too high, which is unfavorable for power consumption and lining life. A good furnace can save electricity and high efficiency.

4. Select the appropriate IF power supply. If the induction melting furnace is too large or too small, it may increase the power consumption. The same large induction melting furnace saves power quickly, and the same fast induction melting furnace saves a lot of power, and the high voltage is lower than the low voltage. Casting time also affects power consumption, preferably 5-10 minutes.

5, try not to use cheap and use low-end equipment, of course, it is not necessarily high prices, some manufacturers to reduce costs, cut corners, low-cost competition, so the worse the equipment consumption is greater. 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 boot 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 transformers is also equal to saving electricity. A 630KVA transformer should be able to convert 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 it.

9, to achieve scientific oven. When the oven is to be closed, the cooling water of the induction coil should be closed (one-third of the normal water volume). It is best to intermittently supply water to maintain the outlet water temperature above 55 degrees, so as to facilitate the smooth discharge of water vapor, which can shorten the oven 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 costly, and the effect was not good.
