Silicon Nitride Riser Tube is a high-performance ceramic component designed specifically for high temperature, high pressure, and highly corrosive industrial environments. It is widely used in fields, such as aluminum alloy casting, magnesium alloy casting, precision metal melting, and semiconductor manufacturing. Silicon nitride (Si3N4) has become a revolutionary alternative to traditional metal or quartz riser tubes due to its excellent physical and chemical properties, helping end-users improve production efficiency, reduce energy consumption, and extend equipment life.
IDEAL SOLUTION FOR HIGH-TEMPERATURE AND CORROSION-RESISTANT CASTING INDUSTRY
FEATURES:
1.Extreme high temperature stability
The temperature tolerance can reach over 1400 degree, and the long-term working temperature can reach 1200 degree. There is no softening deformation, ensuring the stability of molten metal flow.
2.Super strong thermal shock resistance
Silicon nitride has a low thermal expansion coefficient and excellent thermal shock resistance, which can resist severe temperature fluctuations during metal casting and avoid cracking.
3.Excellent corrosion resistance
It has extremely strong corrosion resistance to molten aluminum, magnesium, zinc and other metals and their alloys, avoiding impurity pollution and ensuring metal purity.
4.High mechanical strength and wear resistance
High hardness (Hv>1500), excellent bending strength (>800MPa), resistance to metal liquid erosion, and extended service life to 3-5 times that of ordinary materials.
5.Light weight and energy-saving environmental protection
Low density (3.2g/cm³), reducing equipment load; Non metallic materials and no oxidation or volatilization, reducing energy consumption and carbon emissions.
APPLICATIONS:
1.Low pressure casting of aluminum alloy/magnesium alloy
Used for the production of precision castings such as automotive wheels and engine cylinders, ensuring a smooth liquid lifting process and reducing porosity and defects.
2.High temperature melting equipment
As a guide pipe in vacuum induction melting furnaces and continuous casting systems, it can withstand the dual erosion of molten metal and slag.
