Silicon Nitride Stalk or Riser Tube

Feed Pipe in molten aluminum

Superior thermal shockresistance.Superior corrosion resistance. High strength and easy to handle.Even with flux, and it is hardly eroded. This ensures long life.

Silicon Nitride Riser Tube & Stalk assembly with SUS304 stailess steel flange.

1. Excellent mechanical strength and thermal shock resistance.

2. It has low wettability against molten aluminum, does not infiltrate, and is not easy to stick to aluminum slag inside and outside the tube wall, making daily maintenance more convenient and simple for aluminum casting customers.

3. The silicon nitride riser tube & stalk has high corrosion resistance, therefore the elution contaminants cannot penetrate into the molten aluminum, so as to ensure the high purity of the molten aluminum, thereby helping our customers to produce higher quality aluminum die-casting products.

4. The service life of the silicon nitride riser tube & stalk is 5-20 times that of the traditional stalk, which greatly reduces the number of replacements of the stalk for our customers, and at the same time fully guarantees the continuity and automation of our customers' production, which greatly improve the productivity and productivity for our customers.

5. As long as proper care and maintenance are strictly performed, silicon nitride risers can achieve a service life of more than one year.Applications in molten aluminum​​（Feed Pipe for low pressure aluminum die casting）

Features:

1. Good density and high strength

2. Excellent thermal conductivity and thermal shock resistance

3. It is non-wetting and corrosion-resistant with non-ferrous metal melts such as aluminum melt

4. High temperature resistance, low thermal expansion coefficient
