1. Pipe

　1. The riser tube is used in the aluminum wheel hub industry, with corrosion resistance, good thermal shock stability, low thermal expansion coefficient and good thermal shock resistance.

　2. Crucible heating sleeve, used in liquid aluminum, has good thermal conductivity, corrosion resistance and long service life.

　3. The raceway pipe is used for the floor brick kiln, with a diameter of φ 30-50mm and a length of less than 1500mm. It is resistant to high temperature, does not deform, and has high strength.

2. Beam material

Square beams made of silicon nitride combined with silicon carbide are used in tunnel kilns, shuttle kilns, and inverted flame kilns. They have good bearing capacity. In order to increase the output of the kiln and make full use of the kiln space, silicon nitride combined with silicon carbide is selected. Ideal kiln equipment, and support frames for columns can be used at the same time.

3. Silicon nitride combined with silicon carbide thermocouple protection tube

Thermocouple protection tube, diameter φ 20-50mm, length 1600mm, used in high temperature kilns and various atmospheres, and can also be directly used in fusing liquids.

4. Burner series products

It has the characteristics of oxidation resistance, high strength, good thermal shock resistance, good thermal conductivity, wear resistance and corrosion resistance, and is widely used in high temperature kilns.

5. Other refractory products

It has the characteristics of initialize resistance, high temperature resistance, wear resistance and rapid change resistance, and is suitable for heat exchangers, cold air pipes, etc.

The use of silicon nitride combined with silicon carbide special-shaped products can not only obtain the effect of energy saving, but also ensure that the products are not subject to any pollution, and have a long service life and are easy to operate. We can produce various products according to customer needs.
