MICA ROLL/SHEET is used as an insulation layer between the working lining and induction furnace coil. It has several layers including a slip-plane layer made of mica and strengthen material, a fire-resistant safety-layer, and an electrical and thermal isolation layer. It comes in thicknesses between 0.2-3.5mm and various standard sizes in both roll and sheet forms.
3. Safety-Layer: Fire-resistant and protect coil against
refractory material.
Saperating-Layer: Barrier and protector.
Isolation-Layer: Electrical and thermal protection
Structure
4. Fastening gasket and washer: Tough and special
contraction design for industrial use.
Combine with CaSi Paper, ceramic mat. For industrial
furnace and customized product.
