of the pellets due to the recrystallization of hematite phases
and the formation of recrystallized silicate phases such as
wollastonite, hedenbergite, anorthite, srebrodolskite, and
brownmillerite. This led to a substantial increase in the cold
compression strength (CCS) of the pellets.
Pellets with a basicity of 2.0 have weaker strength due
to insufficient slag bonding, which leads to a decline in their
strength and a slight increase in porosity. This is in contrast
to pellets with a basicity of 1.0, which generate more molten
slag phases and have stronger recrystallized phases.
