A wide variety of products go into the crucible system for induction melting.

Crucibles can be isostatically pressed, for uniform density, or cast in capacities up to 3000kg.  Backing the crucible is a monolithic rammed lining, a slip plane and possibly an outer sleeve or a quick-change crucible-basket assembly; atomising or metering nozzles may be required for bottom pouring

The casting manufacturing system also allows for special shapes to be made, such as ladles, tundishes, launders, pouring spouts.


Fibre Insulationfibre paper

Cerex can supply ceramic blanket and paper offering excellent thermal insulation characteristics for mould wrappings and ladle backup. Two qualities of fibre are available: refractory ceramic fibre and also mineral fibre, which is not classified as carcinogenic.

Ceramic Fibre Blanket is lightweight and flexible, being made from blown ceramic fibres. The long interlocking fibres give it a high strength and low shrinkage; if wet by water or steam, thermal and physical properties remain unaffected after drying.

Fibre blanket is available in a range of densities, 64, 96, 128 and 164 Kgm-3 and thicknesses, 6, 13, 20, 25, 38 and 50mm.

Ceramic fibre paper is made with shorter aluminosilicate fibres in a nonwoven matrix, held in place with a latex binder system. As such, there is some outgassing on first heat-up, although inorganic papers are available if this poses a problem.

Papers are available in thicknesses of 1-8mm; the inorganic range is limited to 1.6mm and 3.2mm.
