Capital manufactures an extensive range of spinel-forming linings. 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 supply a selection of high performance dry rammed products for vacuum induction melting furnaces to meet the mixture of the master alloy.
• Coral V40 • Coral V40-DT • CoralV43 • Coral V43-DT
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.
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.
