Metallurgical Grade Ferrosilicon Nitride
High-temperature erosion resistant FeSiN for ironmaking refractories
Product Overview
Metallurgical grade Ferrosilicon Nitride (FeSiN) is a high-performance refractory raw material produced through controlled nitridation of ferrosilicon under industrial metallurgical conditions. The process forms stable Fe-Si-N phases with enhanced nitrogen incorporation and improved structural stability at elevated temperatures.
In ironmaking systems, it is mainly applied in blast furnace linings, runners, taphole clay, and high-wear refractory zones, where it functions as a structural reinforcement and erosion-resistant phase former.
Importance of Erosion Resistance in Ironmaking
Ironmaking refractories operate in an extreme multi-stress environment:
  • Continuous molten iron flow with high kinetic energy
  • Slag attack with aggressive chemical reactivity
  • Thermal cycling during furnace operation
  • Mechanical abrasion from solid inclusions and flow turbulence
Without sufficient erosion resistance, refractory linings suffer from rapid surface wear, channel enlargement, localized structural collapse, and shortened furnace campaign life.
Erosion Resistance Mechanisms
Formation of Hard Nitride Ceramic Phases
At high temperature, FeSiN promotes the formation of Si₃N₄-based phases that act as hard protective structures against mechanical wear.
Strengthening of Refractory Surface Integrity
The surface layer becomes denser and more resistant to direct molten iron impact.
Reduced Grain Detachment Under Flow Stress
Improved bonding between particles prevents structural breakdown under continuous erosion.
Stabilization of Microstructure in Hot Zones
Internal structure remains intact even under high thermal gradients and slag exposure.
