Saving energy is important! About the use of induction furnace


The principle of induction furnace is to use electromagnetic induction to heat.

Therefore, in the production process, the electricity consumption of electric furnace is a very important problem. Today, we will introduce how to make electric furnace more electricity saving in use.

The same set of equipment, when the electric furnace is running at a slower speed, is more energy saving. At the same time, attention should be paid to the timing and compactness of charging, the size of the furnace, etc. All of these points can simultaneously meet the optimal power consumption. So in general, fast furnaces are more energy efficient than slow furnaces.

The furnace should be charged with the ammeter in mind to make the power supply as stable as possible and to maximize the power output of the power supply device.

Remember, the temperature of the hot metal should be accurately controlled, and the furnace temperature should not be too high or locally too high. This is not good for power consumption and lining life. A good feeder saves electricity and improves efficiency.

Select the appropriate electric furnace power supply equipment. If the furnace is too large or too small, it may increase power consumption. The same large electric furnace can save power quickly, the same fast electric furnace can save power greatly, and the high voltage saves more power than the low voltage. Casting time also affects power consumption, preferably within 5-10 minutes.

Don't try to use a low-grade device instead of a cheaper one. Of course, it doesn't have to be high prices. In order to reduce costs, some manufacturers cut corners and compete at low prices, so the worse the materials used in the equipment, the greater the loss. If the copper is not plated directly and thin copper is used, the device will start to look the same but will consume more and more power.

The entry line is uneconomic and must be large enough, otherwise the long-term losses are staggering.

Develop good starting habits, as full of power as possible, and reduce warming or baking time. When the power is not full, the power factor is low and the loss is large.

Increase transformer utilization. This is equivalent to saving electricity. For example, a 630kVa transformer should be able to produce 13-15 tons of molten iron in 10 hours. If you can only produce 10-11 tons, then your average electricity price must be higher than that.

Ovening and drying with scientific methods.

When dry, the cooling water of the induction coil should be turned off (one third of the normal water volume can be completed). It is best to supply water intermittently and keep the outlet water temperature above 55 degrees to promote smooth discharge of water vapor and thus shorten drying times. Some Stokers fail to pay attention and provide water properly.

As a result, steam escaping from the stove condenses back into water when it meets cold copper tubes, making the stove long, power-hungry and ineffective.
