Refractory Crucible Products

Refractory crucible and metal casting supplies

Anderman Industrial Ceramics currently supply a range of High Alumina, Zirconia and Boron Nitride refractory crucibles. Sizes range from a few cm3 to sectional units capable of holding over ten tonnes of molten metal. Our refractory crucibles, and metal casting supplies, are used mostly in vacuum melting operations but many are also used in Air melting foundries.

We have a wide range of standard sizes and are also able to supply custom size and shaped products to meet exacting customer demands. We also deliver a range of other refractory metal casting supplies such as pouring cups and filters. Our development process allows for many complex shapes to be formed with a high degree of accuracy so systems that require flow control, nozzles or precision launders are also possible

We are also able to supply stopper rods, thermocouple sheaths, Mica and ceramic papers.
