2018-9-1 Agglomeration on this scale has the potential to be detrimental to blast furnace operations, negating the positive impacts gained by grinding the coal prior to injection. As a result of the potential scale of agglomeration, this detrimental effect is likely to occur irrespective of agglomerate/char reactivity.

2019-5-26 The composition of blast-furnace slag agglomerate was similar to the outer coating layer. Chemical equilibrium calculations showed that the original composition of the blast-furnace slag was close to the equilibrium composition, and hence there was no major driving force for reactions between that bed material and K and Ca from the fuel.

2017-12-20 Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine granulometry is produced, and thus iron agglomeration ...
