With density range 800-1000 kgs/m3 , high density calcium silicate insulation board is developed for the non-ferrous industry used for feeding ,casting and molding of molten aluminum and other non-ferrous metals, also can be used for clamping fixture of glass industry . In addition to its insulation, its characteristic of non-stick aluminum exerts a large. Superior strength and good process ability makes it the preferred material for precision CNC machined parts and complex components. There are two types, namely, glass fiber reinforced and carbon fiber reinforced.
Technical calcium silicate is a high performance technical ceramic manufactured from calcium silicate, it is asbestos and quartz free. The densities are ranging from 850 to 1100 kg/m³) and can be machined to very close tolerances. The non-wetting properties make these products ideally suited for non-ferrous metal casting applications. They are also used in a wide range of thermal process applications, and are rated for continuous use to 1832 °F (1000°C).
As a refractory material, it can be used in metal flow control applications in the aluminum industry, and as "hot face" linings in holding furnaces, die casting units and heat treatment equipment.
Technical calcium silicate board has high dimensional stability, and incorporates a unique particle reinforcement to increase fracture toughness and thermal shock resistance. These improvements extend the service life of the refractory components, and reduce operating costs.
Our products are widely used in billet and ingot casters as spouts, floats, trough dams, skim dams etc. Because of low shrinking, some of the material is very suitable for billet casting applications. The various of grades have specially tailored properties designed for use in specific applications in the metal casting industry.
