Why choose 10-50mm Ferro Silicon Nitride lumps for engineering and foundry applications?

The 10-50mm size range for Ferro Silicon Nitride (FeSiN) lumps is highly practical and efficient for engineering and foundry operations, especially in iron and steel metallurgy. This medium granularity ensures optimal reaction control, ease of dosing, and minimal dust generation​ during handling and melting processes.

Larger particles (above 50mm) may not dissolve or react efficiently in molten metal, while smaller particles (below 10mm) can lead to excessive dust, uneven distribution, or rapid reaction, which might compromise product quality. The 10-50mm lump form​ strikes the perfect balance-offering high reactivity when needed, yet controllable and stable​ during the metallurgical process.

These lumps are commonly used in nodular cast iron production, where controlled addition of FeSiN helps achieve uniform graphite nodule formation, improving the final casting's mechanical integrity. They also serve as inoculants or alloying agents​ in steel and special alloy manufacturing, where thermal shock resistance​ and nitrogen contribution​ are essential.
