Frequently Asked Questions
Q: What is the main function of ferro-Si-magnesium cored wire?
A: Its primary function is as a nodulizer, used in cast iron production to improve graphite morphology and enhance the mechanical properties and density of castings.
Q: How does this cored wire work?
A: The cored wire dissolves in the molten steel, releasing magnesium and ferrosilicon. Through chemical reactions, the graphite is spheroidized, improving the metal matrix structure.
Q: What processes are suitable for this material?
A: It is primarily used in the production of ductile iron and vermicular graphite iron to achieve nodularization and inoculation control.
Q: What are the storage requirements for cored wire?
A: Cored wire should be stored in a dry, well-ventilated environment, protected from moisture and oxidation to maintain the activity of the alloy powder.
Q: Can custom production be provided?
A: The ratio of magnesium, silicon, and calcium can be customized based on the molten iron composition and furnace type.
