3 - 6 Mm Silicon Magnesium Fesimg Alloy

Nodulizer introduction:

     Nodularizer, also known as rare earth magnesium ferrosilicon alloy, is an additive that can promote the crystallization of graphite into spherical in cast iron. It is generally used in the field of cast iron. In the process of cast iron, the additive added to the molten iron to make the graphite precipitate in a spherical shape is called nodularizer. The nodulizer containing rare earth elements is called rare earth nodulizer

     Rare earth magnesium ferrosilicon alloy is an alloy made of molten silicon ferrosilicon, calcium, magnesium, rare earth, etc. It is a good spheroidizing agent with strong deoxidation and desulfurization effects. Ferrosilicon, rare earth ore, magnesium metal It is the main raw material for producing rare earth magnesium ferrosilicon alloy.
     The production of rare earth magnesium ferrosilicon alloy is carried out in an ore-heating furnace, which consumes a large amount of electricity, and can also be produced using an intermediate frequency furnace;

Nodulizer effect:

     (1) Spheroidization: make flake graphite into spherical shape
     (2) Anti-recession, keep the spherical graphite without deformation for a long time

Nodulizer application:

     1. Spheroidizing agent, creeping agent and inoculant of cast iron. Rare earth magnesium ferrosilicon alloy, also known as magnesium alloy spheroidizing agent, is a good inoculant with high mechanical strength and strong deoxidation and desulfurization effects;

     2. Additives for steelmaking: light rare earth magnesium ferrosilicon alloys used in the production of spheroidizing agents, creeping agents, inoculants, and also used as additives and alloying agents in the production of steel and iron. Used for refining, deoxidizing, denaturing, neutralizing low-melting point harmful impurities (Pb, arsenic, etc.) and solid solution alloying, forming new metal compounds, etc. to purify steel;
