Capital manufactures an extensive range of linings including spinel and mullite forming products. These have been specifically developed for a variety of metals and some allow for a mixed melting programme. The furnace lining products are complemented by a complete range of toppings, spout, repair, and patching materials.
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 air setting, chemically bonded high strength materials and dry vibration products 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.
