NFJ Passivated Iron

NFJ Passivated Iron Manufacturing Process: Metal oxides with iron content not less than 60% are crushed into particles with a granularity not exceeding 2mm. Light impurities are removed from the raw materials through air and magnetic separation. The particles are then placed in a crucible for calcination, with the addition of rare earth elements for foaming treatment. The material is crushed and evenly mixed with a carbon-based medium, soaked in a reinforcing composite, drained after soaking, and then dried and high-temperature sintered. The sintered material is granulated, subjected to magnetic and air separation, and then placed in a passivation reduction furnace with the introduction of nitrogen for passivation. After drying, magnetic separation, and air separation, the final product is obtained.

Application Analysis:

1. Addressing the issue of rusting of iron particles during use.

2. Solving the problem of excessive stacking density of iron particles, making it inconvenient to use.

3. Resolving the insufficient toughness of iron particles during use.

4. Addressing the difficulty of iron particles in bonding during use.

5. Solving the problem of insufficient contact surface when iron particles are mixed with other materials.
