2 ton series medium frequency electric melting furnace

The rated capacity of the 2 ton series medium frequency electric furnace is 2 tons, which is suitable for metal smelting in the foundry industry. Its power supply structure adopts a series resonance circuit, which can realize a set of medium frequency power supply to supply power to two sets of furnace bodies or multiple sets of furnace bodies at the same time, commonly known as one tow Two medium frequency electric furnace

ONE, Technical parameters of 2 ton series medium frequency electric furnace

1. The 2 ton series medium frequency electric furnace is used for one melting and one protection, that is, one set of series resonance medium frequency power supply supplies power to two sets of furnace bodies at the same time, one furnace body is smelted and one furnace body is insulated. Conventionally, the power of the medium frequency power supply is 1800Kw. That is to say, the smelting power is 1500Kw, the heat preservation power is 300Kw, and the transformer capacity is 2000KVA.
2. The 2 ton series medium frequency electric furnace is used for double melting, that is, one set of series resonance medium frequency power supply supplies power to two sets of furnace bodies at the same time, and the two sets of furnace bodies are smelted at the same time. Conventionally, the power configuration of the medium frequency power supply is 2500Kw, that is to say, two sets of furnaces. The melting power of the body is 1250Kw, and the capacity of the configuration transformer is 3000KVA.
3. The conventional configuration of a 2-ton series medium frequency electric furnace is an medium frequency power supply, two furnace bodies, two resonant capacitors, a filter capacitor, four water-cooled cables, a furnace tilting console, a tilting furnace hydraulic system, four Set of hydraulic cylinders. <

TWO, The scope of application of 2 ton series medium frequency electric furnace

1. Two-ton series medium frequency electric furnace double melting, suitable for casting more than two tons or four tons in weight, where two sets of furnace bodies are required to be melted at the same time, and two furnaces of molten steel are poured at the same time.
2. The 2 ton series medium frequency electric furnace has one melting and one protection, which is suitable for automatic casting production lines. It requires continuous and uninterrupted tapping of molten steel or molten steel without interruption, and the production of sand molds is compatible with the melting rhythm.

THIRD, Advantages of 2 ton series medium frequency electric furnace

1. The current IL flowing through the inductor coil in the series inverter circuit of the 2-ton series medium frequency electric furnace is close to the active current, so Il is very small. Therefore, the electrical loss caused by Il in the inductor coil resistance is very small. The theoretical calculation and The experiment found that above 0.95, the series medium frequency furnace can save more than 10% of electricity. 2. The 2 ton series medium frequency electric furnace can achieve constant power output. For example, in the heating before forging, from cold material to forging temperature of 1250 degrees, or casting smelting from feeding to melting of 1650 degrees, the whole process can maintain full power, which is greatly improved;
2. The 2-ton series medium frequency electric furnace adopts large capacity Cd filtering. First, the three-phase power frequency input current is kept sine wave, and the medium frequency current is all bypassed by Cd at the DC end, and the power adjustment of the series inverter is realized in the inverter bridge. , Controllability, no rectification and commutation gap, no interference to the power grid.
3. The three-phase rectifier bridge of the 2 ton series medium frequency electric furnace is at zero degrees during operation, that is, the DC voltage is the maximum value. The large-capacity cd is directly integrated into the DC terminal, and the power factor of the grid is automatically maintained between 0.95-1 .
4. The start-up success rate of the 2-ton series medium frequency electric furnace is 100%. Because the current flowing through the inverter thyristor is a sine wave, there is no problem of turning on and off of the thyristor. That is, the inverter will not fail to commutation, no There is a startup problem.
