How do you calculate pcd in submerged arc furnace?

The PCD (Power Consumption per ton of metal produced) in a submerged arc furnace can be calculated using the formula:

[ \text{PCD} = \frac{\text{Total Power Input (kWh)}}{\text{Tons of Metal Produced}} ]

To determine the total power input, you need to sum the electrical energy consumed during the smelting process over a specific period. This value is then divided by the total weight of the metal produced in that same period to obtain the PCD in kWh per ton of metal.
