The Role of 90% SiC in High-End Metallurgy
In the production of specialized steels, such as automotive gear steel or stainless alloys, the precision of the deoxidation phase is critical. ZhenAn's 1-3mm SiC 90% serves as a potent dual-purpose additive. Unlike lower-grade deoxidizers, the 90% purity level ensures that the reaction is focused entirely on oxygen removal and stable carbon recovery.
This reaction not only strips oxygen from the molten metal but also delivers high-purity carbon into the solution, effectively replacing more volatile and lower-yield recarburizers.
Strategic Benefits for Steel Plants
Ladle Metallurgy (LF) Efficiency
The 1-3mm grain size is perfectly calibrated for automated dosing systems in ladle furnaces. It penetrates the slag layer effortlessly, providing predictable recovery of Silicon (>92%) and Carbon (>88%), which is essential for hitting tight chemistry specifications.
Inclusion Morphology Control
By rapidly lowering the oxygen potential of the melt, SiC 90% prevents formation of harmful macroscopic oxide inclusions. The resulting SiO2 is easily absorbed into the slag, leading to improved steel internal soundness and fatigue resistance.
Slag Management & Conditioning
High-purity SiC reduces the activity of iron oxides (FeO) in the slag. This creates a more stable, non-aggressive slag that is less corrosive to the ladle's refractory bricks, thereby extending lining life and reducing maintenance costs.

FAQ: Frequently Asked Questions
Why is 90% purity preferred over 88% SiC for ladle trimming?
High-end steel grades require minimal slag volume and very tight chemistry control. SiC 90% provides higher concentration of active elements with fewer impurities like Al₂O₃ and Fe₂O₃, which translates to cleaner steel and more predictable recovery rates.
How does the 1-3mm size affect the deoxidation speed?
The 1-3mm size provides optimal balance. It is small enough to have massive reactive surface area for fast deoxidation, yet heavy enough to sink through the slag without being lost to the furnace's extraction system, unlike fine powders.
Does SiC 90% help in reducing Nitrogen levels?
Yes. Unlike many carbon raisers (such as coal or coke) which can introduce Nitrogen into the melt, SiC 90% is virtually Nitrogen-free. This makes it ideal for Nitrogen-sensitive steel grades used in aerospace and high-strength fasteners.
Can this material be used in induction furnace melting?
Absolutely. In induction furnaces, 1-3mm SiC 90% is an excellent source of both Silicon and Carbon. It promotes more stable melt chemistry and helps create cleaner bath for precision casting.
How does ZhenAn guarantee the size distribution?
We utilize advanced vibratory screening technology and perform sieve analysis on every 50-ton lot. We guarantee that at least 92% of the material falls within the 1-3mm range, ensuring compatibility with automated feeding systems.
What is the storage requirement for SiC 90% granules?
SiC is chemically stable. However, to maintain highest recovery rates, it should be stored in dry, ventilated warehouse. ZhenAn's moisture-proof jumbo bags protect the material from ambient humidity during long-distance sea freight.
