    Ceramic Si3N4 Welding Rolls for Steel Tube Industry

    silicon nitride ceramics is an inorganic non-metallic material. It is a super-hard material, which has lubricity and is wear-resistant; except for hydrofluoric acid, it does not react with other inorganic acids. It is highly corrosive and resistant to oxidation at high temperatures. Moreover, it can resist high thermal shocks. It will not crack when heated to over 1,000°C in the air, cooled rapidly and then heated rapidly. Because of the excellent characteristics of Si3N4 ceramics, it’s often used to manufacture bearings, turbine blades, mechanical seal rings, permanent molds and other mechanical components. In the field of welding of copper stainless, and aluminum tubes, silicon nitride ceramic rolls have natural advantages.
