FAQ
Q1: Can the chemical composition be customized?
A: Yes. Besides standard grades (e.g., Ca28Si60, Ca30Si60), composition can be adjusted based on specific steel grades and process requirements.
Q2: What sizes and forms are available?
A: Common forms include lumps, granules, and powder, with sizes such as 0–10 mm or 10–100 mm. Custom sizing is typically supported for different feeding methods.
Q3: How does it improve steel quality?
A: It reacts strongly with oxygen and sulfur, forming larger inclusions that float easily, thereby reducing impurities and improving steel fluidity, ductility, and overall performance.
Q4: What is the typical packaging?
A: Standard packaging includes 25 kg bags or 1 MT jumbo bags, with customization available.
Q5: Is Calcium Silicon 6030 suitable as a substitute for aluminum deoxidation?
A: Yes. It is often used as an alternative to aluminum in final deoxidation, especially for high-quality and special steels where inclusion control is critical.
