Q1: The usual energy consumption in electric arc furnace steel making is __________ KWh/ton of steel.

ANS:B - 400 - 700

The usual energy consumption in electric arc furnace steelmaking is typically around 400 - 700 kWh/ton of steel. Electric arc furnace (EAF) steelmaking involves melting scrap steel using an electric arc generated by graphite electrodes. The energy required for this process primarily comes from the electricity used to power the electric arc furnace. The specific energy consumption can vary depending on factors such as the efficiency of the furnace, the type of steel being produced, and the scrap quality. However, on average, EAF steelmaking consumes approximately 400 to 700 kWh of electricity per ton of steel produced.
