Mica Slip Plane

Mica slip plane (in roll or sheet form) is primarily designed to separate refractory linings from the coil grout of coreless induction furnaces and offer the following benefits:

· provides a vapor barrier against carbon gases,

· provides superior slip plane properties and protects the inductor coils from the expansion and contraction forces caused by thermal expansion of refractory lining,

· provides electrical insulation between the energized coil and the molten metal,

· optimizes the heat flow to prevent over-sintering of the refractory lining,

· prevents early leakage and subsequent costly damage to the coil,

· facilitates the “push out” of worn crucibles/linings

· extends the life of the crucible/refractory thereby reducing maintenance costs and down time,

· GR-Combi prevents excessive heat loss,

· GR-304 mesh/ GR 304 tanged plate provides a security alarm system for molten metal leakage.

GR-FOIL is a specially cold-formable mica roll with silicon impregnated and glass fiber reinforced. It’s a tearing resistant mica roll with high elasticity and high mechanical stability. It is used widely as a slip plane and coil insulation for coreless induction furnace, wrapping material for crucible form, protective barrier during sintering of lining materials. Temperature resistance is about 800- 1200°C.
