Recycling Waste to Recover Metal Alloys in A Solar Furnace

Abstract

It is known that the metallurgical industry is one of the largest sources of CO2 emissions [1]. As noted in [2] in 2000, ferrous metallurgy accounts for about 4.1% of global CO2 emissions. According to [3], in the production of pig iron, 19.6% of CO2 emissions are from sintering and 62% from blast furnaces. The specific energy consumption in an electric arc furnace is 310–640 kWh / t of steel [4]. In this case, coke is used as a reducing agent. The amount of CO2 emissions in this case is 1630–1960 kg / t of steel.
