1. The fast furnace saves electricity compared to the slow furnace. The same set of equipment is faster than slower power saving. The timing and tightness of the feeding and the size of the furnace will affect the melting speed. These points need to be the best at the same time, the power consumption is the least.
2, the need to take into account the current meter, try to make the power stable. Maximize the output power of the device as much as possible.
3. Precisely control the temperature of molten iron. Do not let the temperature be too high or too high. It is not good for electricity consumption and lining life. A good furnace can save electricity and be efficient.
4. Choose 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 intermediate frequency furnace saves electricity. The high voltage is lower than the low voltage. Casting time also affects power consumption, and it is best be controlled in 5-10 minutes.
5, do not need low-end equipment . The market is fiercely competitive,Some manufacturers cut corners and compete at low prices, and the worse the equipment materials are, the greater the loss. If the copper row is not plated directly and used with a relatively thin 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 the transformer is also equal to power saving. 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 him.
9, scientific oven. When the medium frequency electric furnace is to be blown, the cooling water of the induction coil should be turned off (one third of the normal water volume), and the should be intermittently supplied with 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 costly, and the effect was not good.
Reference power consumption:
Fused iron: 520-610 degrees / ton, 750-980 degrees / ton slow
Fused steel: fast 550-650 degrees / ton, slow 800-1000 degrees / ton
Copper melting: 310-360 degrees / ton, molten aluminum: 200-260 degrees / ton
