Molten Metal Handling Applications
International Syalons has supplied world leading advanced silicon nitride and sialon products to the molten metal handling industry for many years, utilising the outstanding chemical stability of our materials, particularly in contact with non–ferrous molten metals.
The exceptional heat and corrosion resistant properties of advanced silicon nitride and sialon ceramics have been utilised in a range of foundry products for non–ferrous molten metal handling. These include thermocouple protection sheaths, heater and riser tubes, ladles and other foundry products.
Syalon 101 has excellent thermal shock resistance as a result of its high strength, toughness and thermal conductivity. It is thermally very stable and extremely resistant to corrosion by most non–ferrous metals, particularly aluminium and zinc. There is therefore no contamination of the melt. In addition, Syalon 101 is non–wetting for most non–ferrous metals, making it very resistant to build up of dross and therefore very low maintenance.
These unique properties give sialon a significantly better service life over conventional products such as chill cast iron, silicon carbide and aluminium titanate, for example. Our products are used extensively in both primary and secondary aluminium smelters and in the holding furnacess and filter boxes of cast houses. Examples of the foundry products we manufacture include:
