Rojan Heatech Pre-formed Furnace Liners

Rojan Heatech Pre-formed Induction Furnace Liners avoid the undesirable and hazardous environmental effects from in situ rammed silica linings in foundries. They offer easier installation and removal without the dust normally associated with this operation. They also offer enhanced melt lives (some Australian users have achieved up to 50% improvements), greater reliability, as well as reduced down time and require no special skills to achieve a 100% reliable lining.

Aluminium Titanate

Rojan Aluminium Titanate products have outstanding properties, that make them especially suitable for application in industries involved in the melting of aluminium and non-ferrous alloys. These properties include:

relatively high melting point (1860°C)
non-wetted by, and non-reactive with many molten non-ferrous metals and alloys
very low thermal expansion coefficient
exceptional thermal shock resistance
low Young's modulus

 

Applications of Rojan Aluminium Titanate in the aluminium and non-ferrous industries include:

crucibles
pouring spouts
protective covers
riser tubes
stopper rods
thermocouple sheaths
ladles
floats
plugs
sprue bushes

 

Rojan's Aluminium titanate can offer significant life advantages over calcium silicate (40 x life) and fused silica (10 x life).

Silicon Nitride

Rojan acts as agents for International Syalons.  This material is seeing wider application in the aluminium smelting industry due to properties that include not being wetted by molten aluminium, good thermal conductivity and high strength.  This makes it an excellent material for thermocouple sheaths and heater tubes.  Stocks of popular sizes are maintained at our Western Australian based complex.

Rath Range of Products

Rojan are proud to be the Australian distributor for the Rath (Deutschland) GmbH range of refractory materials. The range of products includes:

High temperature vacuum formed shapes for the lining of furnaces up to temperatures of 1800°C in air; shapes can be boards or complex geometries and can be formed in bulk densities up to 1500kg/m3.

Gating systems and sliding gates for use in foundries to eliminate air inclusions and other defects in castings, with a modular assembly design, virtually any foundry situation can be accomodated.

Other products by Rath include Castables, Ceramic Fibre (blanket, rope and paper), Refractory Bricks and specialist materials such as fibre adhesives, rigidisers, coatings and support systems.
