Steelmaking RE FeSiMg Spheroidizing Agent Additive Silver black Blocky
Product introduction:
The rare earth magnesium ferrosilicon alloy refers to an alloy prepared by melting ferrosilicon, calcium, magnesium, rare earth or the like. It is a good spheroidizing agent with strong deoxidation and desulfurization effects. Ferrosilicon, rare earth ore and magnesium metal are the main raw materials for the production of magnesium rare earth ferrosilicon. The rare earth magnesium-silicon alloy is produced in a submerged arc furnace that consumes a large amount of electric power, and can also be produced by an intermediate frequency furnace.
Product advantages:
1. Strong spherical ability, reducing the necessary residual magnesium, ensuring spherical graphite, amorphous processing and overactive components, high sulfur content, low temperature molten iron, eliminating the interference of spherical magnesium materials, rare rare materials affecting flexible iron pipes.
2. The spherical response has good moving conditions, the response is relatively stable, and the efficiency of the rinsing process is better.
3. The performance of flexible cast iron has been significantly improved. The amount of liquid added was increased by 40% compared to the flexible magnesium iron, the temperature at which the spherical magnesium oxide layer was formed was lowered by 50 ° C, and the expansion ratio was lowered from the shrinkage rate to 0.4. Used for shrinkage and crimping. Concrete defects such as pits, subcutaneous pores and cold diaphragms are reduced.
4. Since the thin iron purifies the molten iron and disperses the mixture, the casting defects are reduced, thereby improving the mechanical properties of the flexible iron. The tensile strength, elongation and hardness of flexible magnesium iron are generally increased by 10% compared to flexible magnesium iron.
5. The rare earth spherical magnesium material also has some ball resistance.
