Specifications

Aluminium Titanate Stalk Tube Riser Tube have a long life
No corrosion to aluminum
Lower thermal expansion
Wear-resistance

STA Aluminium Titanate Riser Tube or aluminium titanate Stalk Tube

 

Riser tube for low pressure casting machine is one of important parts. The melting aluminium (with the temperature 700~900) is sent to mould cavity from riser tube by pressure every 3~5 minutes. This asks the riser tube to be resistant of high temperature and thermal shock, no-wetting by molten aluminium, good air tightness .

Characteristics:

Excellent thermal shock resistance

No infiltration with the non-ferrous metal

Excellent wear resistance

Low thermal-expansion coefficient

The service life of the aluminum titanate riser tube can reach 60 days 

Application:

Aluminum Titanate riser tube / stalk tube can be used for the conveying , dosing of non-ferrous metal melts, especially for low pressure die casting of aluminium. The products can keep the purity of low pressure die casting products , and provide for the casting plants with high quality .

 

The aluminum titanate has higher melting point(1860°C±10°C),lower thermal expansion coefficient(RT—1000°C,α<2.0×10-6/°C) and excellent heat-shock resistance. Besides, the aluminum titanate don’t infiltrate with the metal melt(especially the non-ferrous metals) and glass melt. Therefore aluminum titanate can be widely used in the conditions of high-temperature resistance, heat-shock resistance and corrision resistance.
