Silicon Nitride Riser Tube - High-Temperature Resistant Ceramic Tube for Aluminum Casting

Silicon Nitride Riser Tube High Temperature Resistant Ceramic Tube For Aluminum Casting

Description:

The silicon nitride riser tube is manufactured through isostatic pressing and gas pressure sintering processes, offering exceptional density and high-temperature mechanical strength. Designed specifically for aluminum casting, its unique material properties extend service life by over 10 times compared to conventional tubes, while minimizing air leakage and slagging. This results in higher-quality castings and reduced operational costs.

Typical application:

1. Low-Pressure/Gravity Casting: Aluminum wheels, engine blocks

2. Precision Casting: Aerospace components, heat sinks

3. Continuous Casting: Slabs, rods

Feature:

1. Excellent Thermal Shock Resistance

2. High-Temperature Resistance & Low Thermal Expansion

3. Corrosion Resistance & Non-Wetting

4. Long Lifespan & Easy Maintenance
