What is the melting time of an induction furnace?

Power consumption at standard kW/kg ratio for Cast Iron (Ingot) is 560 kWh/ton. Means one ton of Cast Iron (Ingots) requires 560 kW for one hour (kWh). This number is varying for the metal to metal. This number is also depends on the type of the physical charge. This number is different if the physical charge is scrap. Power consumption for the melting cast scrap is 575 kWh/ton.

Require time to melt kg (1 ton) of cast iron is depends on the usage of power consumption from the power supply unit. If the capacity of the power supply is 500 kW and you are operating it on the full power means 500 kW than melting time can be calculated from below equation.

Here, let assume that charge is Cast Iron Ingot. So power consumption will be 560kWh/ton

500kw x time (t)                  560 kW x 1 hour
______________ = ___________________
1 ton                                           1 ton

In order to find time, solve above equation for time (t).
Time (t) =     ( 560 kW x 1 hour  ) / ( 1 ton x 500 kW)

Time (t) =     (560 kW x 1 hour) /  500 kW

Time (t) = 1.12 hour

Time (t) = 1.12 hour x 60 minutes = 67.2 minutes = Approx. 68 minutes

Therefore 68 minutes require to melting kg of cast Iron @ 500 kW.

If the power supply capacity is 700 kW and you are using full power (700kW) than require melting time can be determine using following method.

700 kw x time (t)                 560 kW x 1 hour
______________ = ___________________
1 ton                                      1 ton

In order to find time, solve above equation for time (t).
Time (t) =   ( 560 kW x 1 hour x 1 ton ) / ( 1 ton x 700 kW)
Time (t) =   (560 kW x 1 hour)  /  700 kW

Time (t) = 0.8 hour

Time (t) = 0.8 hour x 60 minutes = 48 minutes

Therefore 48 minutes take for melting kg of cast Iron @ 700 kW.

Power consumption is also depends on the manufacture of the furnace. Below is power consumption for the Electroheat furnace for different metals.

For Cast Iron melting 550-575 kWh/ton require
For SG Iron melting 550-600 kWh/ton require
For MS/SS melting 600-650 kWh/ton require
For light scrap of Aluminum melting 600-625 kWh/ton require For Solid scrap of Aluminum melting 500-575 kWh/ton require For Steel melting 625 kWh/ton require

1. The power of the induction melting furnace is different from the calculation of the operating power of general electromechanical equipment, but the basic principle is figured out, power = voltage × current, while the induction melting furnace power = DC voltage when estimating the power of the intermediate frequency electric furnace × DC current, so it seems that the power unit is Kw, which has a certain relationship with voltage and current.
2. Design and manufacture of induction melting furnaces The calculation power of induction heating furnaces in the industry should be more detailed. When calculating the power of induction heating furnaces in the industry, it is first necessary to determine the material, heating time, productivity, heating temperature, and heating of the induction heating furnace. The weight of the workpiece is considered comprehensively based on years of experience, and the power of the induction heating furnace designed and calculated in this way is relatively accurate.
3. In principle, the formula for calculating the power of an induction melting furnace is: the power of an induction melting furnace: P=(C×T×G) ÷ (0.24×S×η)

C=Specific heat of material (kcal/kg') G=Workpiece weight (kg) T=Heating temperature (')

t=time (S) η=heating efficiency (0.6)

How much power factor should be used as compensation for the 300 kW intermediate frequency melting furnace?

The power grid stipulates that for transformers with a capacity of 200KVA or more, the power factor below 0.9 will be fined step by step, and the power factor above 0.9 will be rewarded step by step. This means that the lower the power factor, the more fines, and the higher the power factor, the higher the reward, up to 0.95.

The power factor of the medium frequency is generally around 0.78, and contains 2-7 harmonics. When the theoretical calculation is compensated until the power factor is 1, 188KVAR reactive power compensation equipment is required. The actual design selection can be selected between 150-200. In addition, the traditional Capacitor bank compensation is easily damaged due to harmonic problems under this working condition, and adding a reactor can only filter out a single harmonic, and the filtering effect is not good. It is recommended to use a low-voltage SVG to filter out harmonics while compensating reactive power.

What is the power of a 3-ton intermediate frequency furnace?
The power of 3T is generally around kw, and the melting material is steel. If you are using other materials, you can call us directly for a consultation. The melting time is about 70 minutes per furnace.

What is the relationship between intermediate frequency power and intermediate frequency DC voltage and DC current?

The intermediate frequency power is the output power of the inverter, and the measurement is the power of the load (that is, the intermediate frequency quenching furnace if there is an output transformer, including the loss power of the output transformer).

The DC voltage is multiplied by the DC current to calculate the DC power. In addition to the intermediate frequency power, the DC power also includes the loss of the filter element (reactor or DC filter inductor), inverter thyristor or IGBT element, and the connecting busbar from the intermediate frequency output to the load.

So the intermediate frequency power is always smaller than the DC power. However, for a good intermediate frequency power supply, the difference between them (or the loss of the power supply) is not large, and it is reasonable within 5%.
