‌Cushioning Function‌ Coil Grout Smooth Surface Insulation Function‌ Coil Grout

The primary function of coil grout is to be applied to the inner surface of coreless induction furnace coils, serving purposes of insulation, protection, and cushioning.

• Insulation: When used between coils, the grout provides excellent insulation, preventing current leakage and short circuits.
• Protection: Characterized by high strength, density, and insulation, the grout is specifically designed to protect coreless medium-frequency furnace coils. It prevents molten metal penetration and shields the induction coils from being punctured by molten metal.
• Cushioning: The smooth surface formed by the grout coating helps cushion the expansion and contraction of the induction coil lining, reducing thermal stress and preventing furnace lining cracks.

Additionally, coil grout offers advantages such as high refractoriness, compactness, strength, smooth surface, strong fluidity, and excellent workability.

Application Scenarios of Coil Grout

1. Foundry & Metal Melting Operations

• Coreless Induction Furnaces: Primary application for ferrous (iron, steel) and non-ferrous (aluminum, copper, zinc) metal melting

• Molten Metal Containment: Critical for preventing coil damage from metal leakage in high-temperature environments (up to 1800°C)

• Furnace Lining Protection: Works as a backup layer between the refractory lining and induction coil

2. Maintenance & Repair Applications

• Coil Reconditioning: Applied during coil refurbishment to restore insulation properties

• Preventive Maintenance: Proactively coats coils to extend service intervals

• Emergency Repairs: Provides rapid protection for damaged coil areas

3. Specialized Industrial Processes

• Vacuum Melting Furnaces: Where electrical insulation is critical

• Precision Casting Systems: For high-quality metal production requiring stable temperatures

• Continuous Casting Lines: Protects coils in prolonged operation cycles
