RE FeSiMg Ferro Silicon Magnesium For Liquid Iron 5mm 10mm

RE FeSiMg Ferro Silicon Magnesium For Liquid Iron 5mm 10mm​

RE FeSiMg Introduction:

     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;

     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 and metallic magnesium are the main raw materials for the production of 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;

Advantages of RE FeSiMg​:

     1. Strong spheroidizing ability, which reduces the amount of residual magnesium required to ensure graphite spheroidization, can treat sub-crystalline products and hypereutectic components, hot metal with higher sulfur content and lower temperature, and eliminates interference with rare earth magnesium spheroidizing agent The harmful effect of spheroidizing elements is a widely applicable spheroidizing agent for the production of ductile iron pipes, which is suitable for the current domestic smelting conditions.

     2. The spheroidization reaction kinetic conditions are good, the reaction is relatively stable, and the process performance of the impulse method is better.
     3. Significantly improve the casting performance of ductile iron, increase its fluidity by 40% compared with magnesium ductile iron, reduce the formation temperature of rare earth magnesium nodularizer oxide film by about 50℃, reduce the expansion value before shrinkage by 0.3 to 0.4%, and make shrinkage and pinch Casting defects such as slag, subcutaneous pores and cold partition are reduced.
     4. Due to the purification of molten iron and dispersion alloying of rare earths, casting defects are reduced, thus improving the mechanical properties of ductile iron. Compared with magnesium ductile iron, the tensile strength, elongation and impact toughness of rare earth magnesium ductile iron are general. To increase by 10%.
