Ceramic riser tubes are a key component for the manufacture of aluminum alloy products (especially for automotive parts) on low pressure casting machines. During casting production, the ceramic riser tube is directly in contact with the aluminum molten alloy so the quality and performance of the ceramic riser tube for the low pressure casting are quite demanding. The ceramic riser tubes produced by Tech Ceramic have not only good thermal shock resistance, high temperature creep resistance, acid and alkali resistance, oxidation resistance, resistance to molten metal corrosion such as aluminum, lead, tin, zinc, etc., but also has excellent thermal shock resistance, can meet the requirements of the low pressure foundry industry.
Riser Tube Material
- Aluminum Titanate
- Silicon Carbide
- Silicon Nitride
- Silicon Nitride Bonded Silicon Carbide
Aluminum Titanate Riser Tubes
Aluminum titanate riser tubes can not be wetted by aluminum alloy liquid and are featured with excellent resistance to thermal shock, low thermal conductivity which saves energy and their outstanding chemical and abrasive resistance ensure high purity of molten alloy.
Nitride Bonded Silicon Carbide Riser Tubes
Riser tubes made from NBSiC are ideal for the melting of non-ferrous metals such as aluminium alloys. NBSC riser tubes are widely used in non-ferrous metal casting industry, especially in aluminum alloy wheel low-pressure casting industry.
Silicon Nitride Riser Tubes
Silicon Nitride has been known for its low wettability and superior corrosion resistance of non ferrous metal melts. Silicon Nitride Low Pressure Riser Tubes offer long service lifetimes, due to good thermal shock resistance and good corrosion resistance.
