High Density Calcium Silicate Board

Specifications

High density calcium silicate insulation board

With density range 800-1000kgs/m3, high density calcium silicate insulation board is developed for the non-ferrous industry used for feeding, casting and molding of molten alumium 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 processability 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.

A. Characteristic

     Special carbon fibre makes it unparalleled strengh and low shrinkage

     Low thermal conductivity, low heat losses at higher temperature

     Non wetted by molten aluminium

     Resistance to thermal shock

     Excellent machining

     Asbestos-free

B. Application

     Furnace inside lining

     Continuous caster tips

     Transition plate

     Baffle plates

     Gasket,stopper

     Through liners

     Floats,Spouts

     Head box
