Capital Refractories offer a full range of coreless induction furnace linings, topping and patching products for a wide range of steels and high temperature alloys.
A range of chemically bonded high strength materials compatible with Capital’s dry linings.
High grade fine hydraulic cements.
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.
Hydraulically bonded multi-purpose castable.
