Steel Pellet

Description and Production procedure of Steel Pellet
Pellets are small balls of iron ore used in steel production. They are one of the
important sources of iron in the manufacture of steel. Pellet production is the
basis of the steel production process. Steel pellets are made from iron ore powder
with additives such as limestone, dolomite, olivine and binder bentonite. The
addition of these additives and adhesives, in addition to preventing a large
amount of gas produced by the evaporation of water from tending to rupture during
the initial stage of heating, can also increase the strength of the particles
before heating. The mixture is then mixed together in a mixer and fed into a disk
or drum to produce coarse particles, usually about 9-16mm. Heat treatment of
coarse particles, including drying, preheating, roasting, post-firing and cooling,
is performed to obtain high metallurgical resistance and appropriate properties.
The original particles are first fed into the hardening machine. Both the direct
grate and the grate-kiln dried the particles in the dry zone, then heated the
particles to about 800-900°C in the preheating zone, and then hardened at
temperatures of about 1200 to 1350°C. The pellet is then cooled to a suitable
temperature for transportation to the unloading equipment.



Application of Steel Pellet
Pellets are widely used in the iron and steel industry. Nothing can replace them.
The structure of the iron ore pellets in the blast furnace allows air to flow
between the pellets, which reduces the air resistance that passes up the charge
layer during smelting. In addition, pellets provide advantages for end users, such
as increased productivity of blast furnaces, increased opportunities for iron
content in charging, and better environmental performance compared to sintering
plants.

As there is a global decline in high-grade block minerals, pellets are made from
low-grade ores and are therefore relatively inexpensive and suitable for mass
production. Their uniform particle size can ensure good permeability of blast
furnace charge, and they have high voltage, good reducibility, high cold strength,
and easy to transport and storage, not crack. Pellets contain fewer harmful
elements, and they can also expand the source of raw materials for iron-making and
smelting fuels.
