Highly insulating coil castables coating refractory material designed specifically for coreless medium frequency furnace coil protection. This advanced material provides superior insulation, protection against molten metal leakage, and thermal stress buffering for industrial furnace applications.

• Protection Function: High strength, high density, and high insulation properties protect induction coils from molten metal breakdown and leakage
• Buffering Function: Smooth surface application buffers thermal expansion and contraction, reducing stress and preventing furnace lining cracks
• Insulation Function: Excellent electrical insulation prevents current leakage and short circuits between coils
• Material Advantages: High refractoriness, superior density, exceptional strength, smooth surface finish, strong fluidity, and excellent operability

Available in multiple formulations including corundum-based and aluminum silicate-based compositions to suit various industrial requirements and operating conditions.
