electric consuption by rolling mills

Dynamic Estimation of Electrical Demand in Hot Rolling Millselectrical arc furnaces), the energy consumption in the downstream mills is far from insignificant. Out of the downstream processes, the hot rolling operation is certainly the largest consumer of energy, both in the form of fuel gas and electricity. The electrical consumption in the hot rolling operation is more than 70 kWh/ton.electric consuption by rolling mills,Energy Management in Small and Medium sized Re-rolling mills .Jun 19, 2017 . Energy Management in Small and Medium sized Re-rolling mills. Energy consumption in small and medium sized re-rolling mills takes place in two forms namely (i) electrical energy, and (ii) fuel or heat energy. Electrical energy is used directly in main rolling process for shaping of hot billets into rolled.

Energy Efficiency in Steel Re–Rolling Mills - Undp

Steel production is an energy-intensive process. It takes nearly 56-66 litres of furnace oil (or 226-269 kg of coal) and 165-192 Kilowatt-hour (KWh) of electricity to produce one ton of steel. The production of one ton of crude steel from iron ore generates about 1.2 tons of solid waste and approximately 2.5 tons of carbon.
