BOF Slag: Turning Waste Into Value
View through CrossRef
The bulk of steel production is met through the Basic Oxygen Furnace (BOF) route. In 2017, 71.6% (1206.9 million metric tons) of the world steel was produced through the BOF route[1]. The impurities present in hot metal are removed in the form of slag upon addition of fluxes and oxygen blowing during the converting process in BOF. This slag is known as steel making slag or BOF/LD slag and is considered as a solid waste by the steel industries. About 150-200 kg of BOF slag is generated per ton of liquid steel depending on the raw material chemistry and the steel grade requirement[2].
