Advantages of high quality nodulizer

What are the basic requirements for spheroidizing agents when a foundry selects one?

• (1) Strong spheroidizing ability;

• (2) Abundant resources, low price, and easy to melt;

• (3) Strong adaptability to molten iron of various components (such as eutectic degree, sulfur content, anti-spheroidizing elements and alloying elements) and temperatures;

• (4) Good spheroidizing reaction kinetics, relatively stable reaction, easy removal of reaction products, small dosage, small temperature drop, and good spheroidizing processability.

         High-quality Nodulizer are reflected in the following aspects:

1. Good affinity: Good Nodulizerhave good affinity with sulfur and oxygen in molten steel. They react less when put into molten steel, but have good deoxidation and desulfurization effects;

2. They can significantly improve the graphite morphology of cast iron: From the name of the Nodulizer, it can be seen that its function is to spheroidize, but in the cast iron industry, this function is particularly important. Putting a good Nodulizerin the molten iron can gradually change the graphite morphology from flake to spherical, greatly improving the quality of cast iron;

3. NodulizerSmall and uniform density, low boiling point: good Nodulizerhas small and uniform density. The small density can automatically float after being put into the Nodulizer. In actual use, the boiling point is much lower than the boiling point of molten iron, which can allow magnesium to be converted into gas at the treatment temperature, and has a self-stirring effect, thereby improving the spheroidization effect;

4. Good content, density and particles: The magnesium oxide content of a good Nodulizeris equal to about 10% of the magnesium content. A good Nodulizeris dense, has no segregation, no shrinkage cavities or shrinkage, and is not powdered. A good Nodulizer has uniform particle size distribution, no powdery alloy, and obtuse polygonal particles are preferred.
