— The T2 brick has 2.07 kg of steel slag. For these constructions, approximately 2.6 Mt/year of steel slag and 454.7 thousand tons of iron ore tailings would be consumed. Considering the BOF slag generation ratio per ton of steel (Wimmer et al. 2014), the total amount of BOF steel slag produced in Brazil in 2015 was 3.1 Mt. In doing so, the ...
— Under the condition of global carbon neutrality, reducing carbon emissions has become a new trend in the development of the steel industry [1,2,3].The blast furnace is the largest vertical reactor, which currently bears the vast majority of the current hot metal production work [].In the normal production process, the blast furnace hearth is full of …
According to Pandey, in comparison to normal highways, the ones made out of steel slag are 30 per cent less thick because of better material characteristics. "The construction costs of such steel slag roads will also be around 30 per cent cheaper. The Hazira road uses around 1 lakh tons of processed steel slag."
