Silicon nitride ceramic refining tube

Si3N4 or Sialon/Syalon is the suitable material for the refining process in molten aluminum.

●Good thermal shock resistance and high-temperature mechanical strength, light weight,high strength, and easy to process.

●Molten aluminum’s low wettability prevents stick of slagging in the tube, thus easy to maintain and operate.

●With unique and novel structure, the refining tube can guarantee refined powder get into the furnace timely, with its retractile character.

●Si3N4 has excellent corrosion resistance and wear resistance, and ensure longer working life. If proper maintenance, the actual using life can be up to 2-3 years.

●Our company can supply the refining tube as per customers’ needs.
