SiC Lift Tube

Material: Silicon Nitride bonded Silicon Carbide(N-SiC)

Applications: widely used in nonferrous metal casting area, especially low pressure casting for aluminum alloy wheel.

Working Temperature: ≤1600℃

Advantages

1. Anti-corrosion and anti-melting, no contamination to metal liquid.

2. No slag accumulated, no aluminum adhered, Airproof, preventing air hole on casting piece.

3. Good at thermal shock resistance, no crack

Si3N4 bonded SiC is a new type of high-grade refractory materials. It includes radiant tube, brick, deformed parts and so on. These products, which have energy saving, environmental protection, high temperature resistance, corrosion resistance and other advantages, can be widely applied in the field of Urban construction, Kiln Furniture, Steel and non-ferrous mental, chemical construction materials, etc.

Si3N4 bonded SiC products with high strength in normal temperature. Under 1200-1400℃, it can keeps almost same strength and hardness with it under normal temperature. As the environment is different, the maximum service temperature can reached up to 1650-1750℃.

These products are obtained by reaction sintering of a mix of SiC with Si fines and additives and nitridation in N2 atmosphere at~1450℃

The following reaction would take place:

3Si+2N2→Si3N4

3Si+SiO2+2N2→2Si2N2O

Si3N4+SiO2→2Si2N2O

Si3N4  Si2N2O act as binder for the SiC grains
