Product Introduction
Refractory Spinel is a high-temperature refractory material synthesized from magnesium oxide (MgO) and aluminum oxide (Al₂O₃), mainly used in industrial furnace linings such as steel, glass, and cement.
Product Applications
High-Temperature Furnace Lining Material
Refractory Spinel is widely used in high-temperature industrial furnace linings, such as those used in steelmaking, cement rotary kilns, and ceramic kilns. Its temperature resistance reaches approximately 2000°C, ensuring the structural stability of the furnace in extreme environments.
Thermal Shock and Corrosion Resistant Layer
Due to its excellent thermal shock resistance, Spinel can withstand rapid temperature cycles without cracking. It also offers high corrosion resistance to slag and chemical media, extending the life of the furnace.
Glass and Non-Ferrous Metal Melting Furnace Lining
In glass and non-ferrous metal melting equipment, Spinel resists molten materials and corrosion, maintaining lining integrity and reducing maintenance frequency and downtime costs.
Company Advantages
Electric Arc Furnace Synthesis Process
The company uses multiple electric arc furnaces (EAFs) for high-temperature synthesis of refractory spinel, achieving complete raw material reaction and a stable MgAl₂O₄ phase ratio in the product, making it suitable for high-temperature linings with stringent phase structure requirements.
Multi-stage Magnetic Separation System
Using proprietary magnetic separation and screening equipment, iron impurities and unreacted residues are effectively controlled, resulting in high-purity finished products that meet the stringent chemical composition requirements of high-purity applications such as glass furnaces.
Sufficient Annual Production Capacity
Leveraging a refractory plant equipped with both an EAF and MRF, the company’s annual production capacity for spinel products meets the needs of multiple industrial customers, enabling quarterly and semi-annual delivery schedules to reduce procurement and inventory pressure.
