Advantages of rare earth magnesium ferrosilicon alloys 

What are the advantages of rare earth magnesium ferrosilicon alloys:

1. Strong spheroidization ability, reduce the amount of residual magnesium required for graphite spheroidization, can process subcrystalline products and supereutectic components, molten iron with higher sulfur content and slightly lower temperature, eliminating the harmful effect of interfering with rare earth magnesium nodularizer nodularizing elements, for the production of ductile iron pipe is a widely applicable nodularizer, adapt to the current domestic smelting conditions.　

2. The kinetic conditions of the spheroidization reaction are good, the reaction is relatively stable, and the process performance of the rush-in method is better.

3. Improve the casting performance of ductile iron, increase the fluidity by 40% compared with magnesium ductile iron, reduce the formation temperature of rare earth magnesium nodularizer oxide film by about 50 °C, reduce the expansion value before shrinkage by 0.3 to 0.4%, and reduce casting defects such as shrinkage looseness, slag inclusion, subcutaneous pores, cold partition, etc.

4. Due to the purification of molten iron and dispersion alloying of rare earths, casting defects are reduced, thereby improving the mechanical properties of ductile iron, and compared with magnesium ductile iron, the tensile strength, elongation and impact toughness of rare earth magnesium ductile iron are generally increased by 10%.

5. Yttrium-containing rare earth magnesium nodularizer also has a certain ability to resist spheroidization and recession.

The company sells nodularizers, there are 3-8#, 5-8#, etc., you can consult for details!
