Description
RE FeSiMg the additive that can promote the crystallization of graphite in ball milled cast iron into a spherical shape is generally used in the field of cast iron. In the process of casting iron, the additive added to the molten iron to make the graphite precipitate in a spherical shape is called a nodulizer, and a nodulizer containing rare earth elements Rare earth spheroidizing agent.

Advantages
1. RE-FeSiMg:Strong spherical ability, reduce the amount of residual magnesium needed to ensure the spherical shape of graphite, crystallize processing and overactive components, high quality sulfur content, low temperature molten iron, interference of magnesium spherical material. Excludes, affects rare rare material flexible iron pipe.
2. RE-FeSiMg:The spherical response has good moving conditions and the response is relatively stable, improving the performance of the flushing process.
3. RE-FeSiMg:The castability of soft iron is greatly improved. Compared with magnesium soft iron, the added amount of liquid is increased by 40%, the forming temperature of magnesium spherical oxide film is reduced by 50°C, and the magnification is reduced from the shrinkage rate to 0.4. For contraction and clamping. Reduces concrete defects such as dimples, subcutaneous pores, and cold partitions.
4. RE-FeSiMg:Thin iron purifies molten iron and disperses the mixture, thus reducing casting defects and improving the mechanical properties of soft iron. The tensile strength, elongation and hardness of magnesium soft iron are generally increased by 10% compared to magnesium soft iron.
5. RE-FeSiMg:Rare earth magnesium spherical material also has a certain anti-spherical ability.
