Nodulizing agent, also called rare earth magnesium ferrosilicon alloy, is an additive that can promote the crystallization of graphite in ductile cast iron into a spherical shape. It is generally used in the field of casting cast iron. During the casting process, additives added to the molten iron to precipitate graphite in a spherical shape are called spheroidizing agents. , and the spheroidizing agent containing rare earth elements is called rare earth spheroidizing agent;
Rare earth magnesium ferrosilicon alloy is mainly an alloy formed by melting ferrosilicon, calcium, magnesium, rare earth, etc. It is a good spheroidizing agent and has strong deoxidation and desulfurization effects. Ferrosilicon, rare earth minerals, metals Magnesium is the main raw material for the production of rare earth magnesium ferrosilicon alloys;
Spheroidizing agent supply model: 3-8 spheroidizing agent, 5-8 spheroidizing agent, 7-8 spheroidizing agent
3-8.5-8.7-8 refers to the brand name of the spheroidizing agent, which is equivalent to a person's name. The spheroidizing agent can also be called rare earth magnesium ferrosilicon alloy.
Among them, 3, 5, and 7 in 3-8.5-8.7-8 represent the rare earth content, while 8.8.8 in 3-8.5-8.7-8 represent the magnesium content
