Crucible offers durability and reduced energy consumption

The Molten Metal Systems business of Morgan Advanced Materials has extended its Syncarb Z2 crucible family with the introduction of a new crucible designed to provide longer service life and increased energy savings for customers in the aluminium processing industry.

Designed specifically for aluminium melting and holding applications, the Syncarb Z2 e2 product has undergone extensive laboratory and field testing with results confirming an operational performance that surpasses alternative crucibles in the areas of durability and reduced energy consumption.

The entire Syncarb Z2 line is composed of isostatically pressed, hybrid ceramic bonded crucibles with a high silicon carbide and graphite content. They display a higher breaking strength, due to an improved granulation process, resulting in increased resistance to damage and higher stresses during operation and handling.

The new Z2 e2 also brings a number of material and structural advantages to help improve crucible performance and foundry operations. As well as offering a 56 per cent higher transverse breaking strength than some other energy efficient crucibles, the Z2 e2 maintains integrity at relatively higher values due primarily to the granulation of the mix, processing parameters and advanced materials used.

In addition, through its advanced glaze technology, the Z2 e2 showed an average 10 per cent increase in oxidation resistance over competing products in both five and ten day Loss On Ignition (LOI) tests.

Morgan has been able to develop a crucible that has been scientifically proven by an independent laboratory to achieve superior thermal conductivity over all working ranges while maintaining a standard wall thickness. This achievement results in increased energy efficiency and savings for those operating in an environment of fluctuating and increasing energy prices.

Furthermore, while thermal conductivity will degrade over time as any crucible oxidises, the oxidation process occurs slower in the Morgan Syncarb Z2 e2 crucibles. This reduced degradation, combined with a higher thermal conductivity, results in further energy savings compared with alternative products, throughout its lifetime.

All this translates to longer run times, more cycles, less energy usage and an overall melting solution advantage.
