Description

Ceramic bushing is located between the riser pipe and the lower mold.

Aluminum titanate ceramics can improve the quality of cast aluminum. The use time is about 50 days. The price is lower than that of silicon nitride ceramic. It is a cost-effective riser material. Mainly used for low-pressure cast aluminum in key parts such as automobile steel rims and cylinders.


Property

1. Excellent thermal shock resistance.

2. It does not infiltrate with non-ferrous metal solutions such as aluminum melt

3. Higher room temperature and high temperature strength.

4. Excellent wear and corrosion resistance.

5. Low thermal expansion coefficient.


Production background of aluminum titanate riser:

Aluminum titanate riser tube has high room temperature and high temperature strength, corrosion resistance, low thermal expansion coefficient and good thermal shock resistance. It does not drop slag, does not burst, and has excellent performance such as long service life. It is not compatible with aluminum solution. The characteristics of infiltration make it an ideal material for riser pipes, nozzles, risers, etc. in the metallurgical low-pressure casting industry. At present, high-quality riser pipes mainly rely on imports in China. First, the cost is high, and second, the continuity of production cannot be guaranteed. The birth of the aluminum titanate ceramic riser tube has far-reaching significance for the transformation and upgrading of my country's traditional industrial technology and the revitalization of the automotive electronics industry.
