In the high-temperature operation of electric arc furnaces (EAF), the lining materials must withstand extreme temperature fluctuations, as well as erosion from molten steel and chemical slag. Choosing the right refractory materials not only extends the life of the furnace but also improves production efficiency. Zhongtang Materials (ZTM) offers a comprehensive range of refractory material solutions, addressing both construction and maintenance materials to help you quickly find suitable products that ensure efficient operation of electric arc furnaces (EAF) under demanding conditions.
1. Construction Refractory Materials
ZTM’s construction refractory materials are specifically designed to cope with the extreme high temperatures and chemical corrosive environments of electric arc furnaces (EAF), ensuring durability and stability for the furnace body, bottom, and key components.
Magnesia Bricks and Magnesia-Carbon Bricks (MgO-C bricks)
ZTM provides magnesia bricks and magnesia-carbon bricks (MgO-C bricks) that play a crucial role in the furnace body, bottom, and tapping areas of electric arc furnaces (EAF).
- Magnesia Bricks are primarily composed of high-purity fused magnesia, exhibiting excellent high-temperature resistance and slag erosion resistance, making them particularly suitable for the bottom and body of the furnace, maintaining long-term stability.
- Magnesia-Carbon Bricks (MgO-C bricks), made from magnesia and flake graphite, combine outstanding thermal shock resistance and chemical erosion resistance, making them ideal for areas subjected to high-temperature molten steel impacts and extreme loads, providing additional protection for these vulnerable areas.
EBT Bricks and Filling Sand for EBT
The tapping area of the electric arc furnace (EAF) is a critical part, and ZTM’s EBT bricks and filling sand for EBT offer comprehensive protection for this region.
- EBT Bricks feature excellent thermal shock resistance and wear resistance, ensuring structural stability in frequently operated high-temperature environments and extending the service life of the equipment.
- Filling Sand for EBT ensures the sealing of molten steel during flow, preventing leaks and ensuring safety and continuity during operations.
Bottom Ramming Mass and Precast Product
The bottom and top of the electric arc furnace (EAF) also require high-strength refractory materials, and ZTM’s bottom ramming mass and precast products provide the best construction solutions for these areas.
- Bottom Ramming Mass is a high-density, high-erosion-resistant material specifically designed to enhance the stability of the furnace bottom and extend its service life.
- Furnace Roof and Precast Block for Tapping Spout provide excellent thermal shock and high-temperature resistance for the top and tapping channels of the electric arc furnace (EAF), reducing maintenance frequency and improving overall equipment efficiency.
2. Maintenance Refractory Materials
Maintenance is crucial during the daily operation of electric arc furnaces (EAF). ZTM offers gunning mass and hot repair mass that efficiently address lining damage, ensuring continuous and effective operation of the equipment.
- Gunning Mass: ZTM’s gunning mass has high adhesion properties and is used for online repairs in electric arc furnaces (EAF). It can quickly repair cracks and erosion in the lining caused by high temperatures and wear, reducing further damage and extending the lining’s lifespan.
- Hot Repair Mass: Designed for non-shutdown repair work, hot repair mass can rapidly solidify and complete repairs under high-temperature conditions. These materials not only minimize equipment downtime but also ensure continuity in production, making them an ideal choice for efficient maintenance of electric arc furnaces (EAF).
