In the harsh, high-heat environments of foundries and steel mills, only a few materials can endure high temperatures like sheet mica. Despite advances in insulation technology, mica remains a critical component in thermal and electrical protection systems — trusted by manufacturers for its unmatched performance under pressure.
Withstanding Extreme Temperatures
Steelmaking processes routinely expose equipment to temperatures above 1000°C. Sheet mica’s exceptional thermal resistance makes it ideal for:
- Furnace and ladle insulation
- Heat shields in induction and arc furnaces
- Protective liners for high-heat tools
Mica doesn’t melt, warp, or break down — even after repeated heating and cooling cycles — making it one of the most reliable materials for thermal management in heavy industry.
Protecting Electrical Systems in Harsh Environments
Steel plants rely on powerful electrical systems to drive arc furnaces, convey molten metal, and operate heavy machinery. Mica sheets serve as:
- Arc barriers and dielectric separators
- Insulation for busbars, terminals, and transformers
- Flash guards to prevent short circuits in high-voltage areas
Its ability to insulate at high temperatures ensures safe, uninterrupted operation even in the most demanding industrial conditions.
Proven Performance in Every Application
Whether it’s used in insulation pads for tundishes or slot liners in high-amp motors, mica is proven to extend equipment life and reduce downtime in steelmaking operations.
