Ferro Silicon Nitride for Wear Resistance in High-Stress Steel
Ferrosilicon nitride is a mixture with Si3N4 as the main component,
usually accompanied by free iron, non-ferrosilicon nitride and a
small amount of other components. It is widely used in the fields
of steelmaking and refractory materials, especially in blast
furnace mud. It can significantly improve the plugging performance
of the mud and meet the needs of blast furnace tapping. The
stability of ferrosilicon nitride performs well at high
temperatures, especially in nitrogen atmosphere, where it can
maintain high stability.
Research on the high-temperature stability of ferrosilicon nitride
under nitrogen atmosphere shows that the phase composition changes
with the increase of the calcining temperature. For example, at
1500°C, the phases present in the sample are β-Si3N4, α-Si3N4,
Si2N2O, SiC and Fe3Si; while at 1600°C, the content of β-Si3N4
increases, and three ferrosilicon alloys, Fe3Si, Fe5Si3 and FeSi,
coexist. , α-Si3N4 and Si2N2O disappear; when the temperature rises
to 1700°C, the β-Si3N4 content decreases significantly and α-Si3N4,
Fe5Si3 and FeSi phases coexist, and the Fe3Si phase disappears.
The stability of ferrosilicon nitride is also related to its
particle size. The coarser ferrosilicon powder particle size is
conducive to the nitridation reaction, because the coarser
ferrosilicon powder will not cause the nitridation reaction to be
too fast in the early stage of the reaction, thus avoiding
over-sintering. In addition, ferrosilicon nitride has a series of
advantages such as high refractory resistance, good corrosion
resistance, high mechanical strength, good thermal shock
resistance, low thermal expansion rate and high oxidation
resistance. These characteristics make ferrosilicon nitride a good
application in refractory materials, especially in castables, gun
clay and composite refractory materials.
In summary, ferrosilicon nitride exhibits good stability in
high-temperature environments due to its excellent physical and
chemical properties, which makes it widely used in the refractory
and steelmaking industries.
