Basic Information of Silicon Manganese Furnace Construction
A silicon-manganese furnace is a specialized smelting equipment primarily used for producing silicon-manganese alloy. Silicon-manganese alloy is a crucial alloy material widely used in steelmaking.
Our Mongolian customer has purchased high-alumina bricks, castable refractories, phosphate-bonded alumina cement, and high-alumina aggregates for lining their silicon-manganese furnace.
What Are The Advantages Of Using High-Alumina Bricks?
- High Temperature Resistance: Refractory materials must withstand the high-temperature environment inside the furnace and have a high melting point.
- Slag Resistance: Refractory materials should resist erosion from furnace slag to prevent premature damage to the lining.
- Thermal Shock Stability: The temperature variations in the silicon-manganese furnace are significant, so refractory materials should possess good thermal shock stability to prevent cracking.
- Mechanical Strength: Refractory materials should have sufficient mechanical strength to withstand the impact and pressure of materials inside the furnace.
- Thermal Conductivity: Select appropriate thermal conductivity based on the temperature requirements of different areas.

Structure of the Silicon-Manganese Furnace and Common Refractory Materials
- Furnace Shell: Furance shell provides the main structural support of the furnace, bearing the high temperatures and pressure inside. Commonly made of steel plates and refractory castables.
- Furnace Lining: Furnace lining is located on the inner wall of the furnace shell. It serves to insulate, resist wear, and protect the shell. This area commonly uses high-alumina bricks, carbon bricks, magnesia-carbon bricks, magnesia-carbon castables, high-alumina castables, etc.
- Electrodes: Electrodes generate high temperatures through electric arcs to melt the materials inside the furnace. Graphite electrodes are commonly used in this area.
- Cooling System: Cooling system is used to cool the furnace body and electrodes to prevent overheating of the equipment. This area commonly employs materials such as copper pipes and cast iron.
