What Is Fused Magnesite?
Fused magnesite is produced by melting high-purity magnesite (MgCO₃) in electric arc furnaces at temperatures above 2750°C. Once cooled and solidified, the material forms large crystalline blocks of nearly pure magnesium oxide (MgO) — a compound highly resistant to heat, slag, and chemical corrosion.
This makes fused magnesite an essential component in refractories used for steelmaking, cement kilns, glass furnaces, non-ferrous metal refining, and other extreme environments.
Key Benefits of Fused Magnesite in Refractories
- Exceptional Heat Resistance: With melting points over 2800°C, fused magnesite easily withstands the most intense thermal loads.
- Chemical Stability: It resists corrosion from alkaline slags, making it ideal for linings in basic oxygen furnaces (BOFs) and electric arc furnaces (EAFs).
- High Purity and Low Reactivity: Its low silica and iron content ensures minimal reactions with molten materials, reducing contamination.
- Mechanical Strength: The large crystal structure of fused magnesite enhances structural integrity and resistance to spalling.
Applications in High-Temperature Industries
- Steelmaking (BOF, EAF, Ladle Furnace): Used in magnesia-carbon bricks, gunning mixes, and ramming masses for critical areas like slag lines and sidewalls.
- Cement Industry: Used in linings of rotary kilns where thermal cycling and alkali attack are prevalent.
- Non-Ferrous Metallurgy: Suitable for furnaces used in copper and nickel smelting.
- Ceramic and Glass Manufacturing: Used for its stability and durability at high temperatures.
