How Is Steel Waste Disposed Of And Recycled? – Insight Today

May 08, 2018· Solid waste is an essential by-product of the production of steel and iron. Unfortunately, due to the huge amounts of steel produced each year, the solid wastes resulting from the refining process results in significant environmental pollution. In the past, the grime and sludge produced by steel plants went by the name of 'waste'.

Iron & Steel — HeatCalc

The basic oxygen furnace (BOF) uses oxygen to refine pig iron into steel. The heat required for the refining and melting process is provided by the exothermic reaction within the furnace. For U.S. production, the very high temperature off-gases from the BOF equal 27 TBtu/yr of waste. heat.
