Silicon nitride bonded silicon carbide products - shaped products

Product Description:

Features: use temperature of 1400 DEG C, has good thermal stability, thermal shock performance is better than the ordinary refractory material and recrystallization of SiC, antioxidant, acid and alkali resistance, wear resistance, and has higher flexural strength. In the aluminum (Al), lead (Pb), zinc (Zn), copper (Cu) as the molten metal corrosion resistance, erosion resistance, no pollution.

  Pipe.

  1, the lift tube, aluminium wheel hub for industry, low expansion coefficient and good thermal shock resistance and strong corrosion resistance, good thermal shock resistance, thermal.

  2, the crucible heating sets, for aluminum liquid, it has good thermal conductivity, corrosion resistance, long life.

  3, the raceway tube, used for ground brick furnace, diameter 30-50mm, length less than 1500mm, high temperature resistance, no deformation, high strength.
