INTRODUCTION:
Silicon Nitride Heater and Riser Tubes Silicon Nitride Heater and Riser Tubes Zhok manufacture a range of advanced ceramic
silicon nitride immersion heater and riser tubes for use in the aluminium
and non–ferrous molten metal handling industries.
Fine silicon nitride foundry products offer long life,
improved process reliability and are cost effective compared to
competitive materials, such as cast iron and refractory ceramics,
such as silicon carbide and aluminium titanate.
Zhok Si3N4 is an alloy of silicon nitride and combines excellent thermal
and mechanical properties.
Zhok Si3N4 has found extensive use in nonferrous molten metal
applications as a result of its high strength,
toughness, thermal shock resistannce, corrosion resistance and
its non–sticking nature in contact with aluminium and its alloys. Immersion heater tubes are the most effective method of
heating the melt in the aluminium processing industry.
Zhok Si3N4 tubes offer protection to heating elements due to
its excellent physical properties. The range of heater/riser tubes available is very diverse,
although we are limited to a maximum outside diameter of 200mm
and maximum length of 1500mm.
A selection of the tubes we currently manufacture are shown
in the tables below.
Other tubes can be manufactured to customer requirements.
Integral flanges can be made up to 30mm greater than the tube outside diameter.
