Product Introduction:
Table of Contents collapse
Silicon nitride ceramic rollers are mainly made of high-purity silicon carbide aggregates, silicon powder and other additives, and fired in a nitride furnace according to the theory of in situ generation.It has excellent resistance to the penetration and corrosion of various molten metals and alloys (such as aluminum, lead, tin, silver, brass, and nickel, etc.).
Features:
- High mechanical strength
- High fracture toughness
- Outstanding wear resistance
- Excellent thermal shock resistance
- Good resistance to oxidation
Application:
It can be widely used in thermal equipment in building sanitary ceramics, daily ceramics, electric ceramics, smelting industries (aluminum, copper, zinc, steel, etc.), heat treatment, environmental protection and other industries.
