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.

The prime features of  Si3N4 Silicon Nitride Ceramic

1. Extraordinary thermal shock, it can withstand up to1000ºC
2. It’s easier to do precise machining, the tolerance can be 0.001mm
3. Chemical corrosion resistance under high temperature, except for HF and H3PO4
4. Extreme wear and abrasion resistance., much better than stainless steel
5. Great mechanical properties, hardness, compressive and flexural strength are much higher stainless steel
