spheroidizing agent effect

Spheroidizing agent, also known as rare earth magnesium ferrosilicon alloy, is an additive that can promote the crystallization of graphite in ball milled cast iron into a spherical shape. It 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 spheroidizing agent. The spheroidizing agent containing rare earth elements is called rare earth spheroidizing agent

Nodulizer model:

7-8 spheroidizing agent

Rare earth magnesium ferrosilicon alloy is an alloy made of ferrosilicon, calcium, magnesium, rare earth, etc. through melting. It is a good spheroidizing agent and has a strong deoxidizing and desulfurizing effect. Ferrosilicon, rare earth ore, metal magnesium 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 a submerged arc furnace, which consumes a lot of electricity, and can also be produced in an intermediate frequency furnace;

Spheroidizing agent effect:

(1) Spheroidizing: making flake graphite spherical

(2) Anti-decay, keep the spherical graphite without deformation for a long time

Nodulizer application:

1. Spheroidizing agent, vermicularizing agent and inoculant for cast iron. Rare earth magnesium ferrosilicon alloy is also called magnesium alloy spheroidizing agent. It is a good inoculant with high mechanical strength and strong deoxidation and desulfurization effects;

2. Steelmaking additives: light rare earth magnesium ferrosilicon alloy used in the production of spheroidizing agents, vermicularizing agents and inoculants, and also used as additives and alloying agents in the production of steel and iron. Used for refining, deoxidation, denaturation, neutralization of low melting point harmful impurities (Pb, arsenic, etc.) and solid solution alloying, forming new metal compounds, etc. to purify steel;


Spheroidizing agent size:

Spheroidizing agent supply particle size: 5-30mm (also can be processed according to customer requirements), gray-black solid thickness does not exceed 100mm.


Nodulizer packaging: 25 kg mother-in-child bag plus ton bag, or packaged according to customer requirements
