Silicon nitride ceramic welding rollers

Silicon nitride ceramic welding rollers, also known as aluminum tube welding ceramic rollers, harness the unique properties of silicon nitride material to meet the demands of high-temperature welding processes:

High Wear Resistance and Heat Resistance

Silicon nitride boasts a Vickers hardness up to 1500 HV and can withstand temperatures up to 1200°C, making welding rollers excel under continuous high-temperature conditions, ideal for metal processing applications, especially aluminum tube welding.

Excellent Mechanical Strength

With an elastic modulus of 290 GPa and flexural strength of 600 MPa, silicon nitride ensures stability and durability of welding rollers under high pressure.

Thermal Shock Resistance and Low Thermal Expansion Coefficient

It exhibits a thermal shock stability coefficient at 500°C and a thermal expansion coefficient of 3.1×10^-6/°C, ensuring dimensional stability and consistent performance of rollers in environments with significant temperature fluctuations.

Smooth Surface Treatment

The surface of welding rollers is exceptionally smooth, reducing surface damage to metal sheets or pipes during welding and enhancing operational efficiency.

Silicon nitride ceramic welding rollers play crucial roles in multiple key industrial sectors:

Metal Processing Industry

Especially in applications like aluminum tube welding, these welding rollers are used for conveying and supporting pipes or metal sheets, needing to withstand continuous high pressure and high temperatures.
