Slip plane Material (Mica)

The slip plane is positioned against the coil screed to provide a smooth surface. This is essential for uninhibited reversible movement of the refractory lining caused by its thermal expansion and contraction. The mica also offers a degree of protection against metal penetration.

Mica Mesh
A sandwich of metal mesh between two layers of mica is available which is used in systems that give early warning of metal penetration through a lining.
