Ultra-Clean Steel Production: Reach rigorous oxygen-reduction targets for specialty alloys and automotive-grade steels with 90% purity.
Rapid Dissolution Sizing: The 1-3mm precision granules ensure a high surface area for immediate reaction during ladle furnace (LF) processing.
Superior Recovery Rates: Achieve over 94% Silicon and 90% Carbon yield, reducing the reliance on high-cost ferrosilicon and synthetic graphite.
Refractory Longevity: Actively conditions the slag to reduce its chemical aggressiveness, shielding your furnace and ladle linings from erosion.
ZhenAn Global Logistics: Benefit from a Tier-1 industrial supply chain with ISO-certified consistency and dedicated maritime support for bulk orders.
The Metallurgical Edge of 90% Silicon Carbide
In precision steelmaking, the chemical potential of your deoxidizer dictates the final toughness and fatigue resistance of the metal. ZhenAn's 1-3mm SiC 90% is a high-density metallurgical tool that performs under the most demanding ladle conditions.
The dissociation of SiC in the molten bath is a critical exothermic event: SiC + 3[O] → SiO₂ + CO↑
This reaction not only strips the melt of oxygen but also releases thermal energy, assisting in maintaining the liquidus temperature without additional electrode power.
Performance Excellence in Steel Plant Operations
Precision Ladle Trimming
The 1-3mm grain size is engineered for gravity-fed or pneumatic injection systems. Its uniform flowability ensures that the calculated dose of Carbon and Silicon reaches the melt precisely when needed, ensuring "on-spec" chemistry for every heat.
Inclusion Morphology Management
High-purity SiC 90% facilitates the formation of liquid, easy-to-float silicates. By managing the oxygen potential effectively, it prevents the development of hard, angular alumina inclusions that can lead to nozzle clogging during continuous casting.
Slag Management & Energy Efficiency
Our 90% SiC granules reduce the FeO content in the slag, creating a more stable "reducing" slag. This environment protects expensive subsequent alloy additions (like Chromium and Vanadium) from oxidation, significantly lowering the "cost per ton" of the final alloy.

Why Procurement Teams Partner with ZhenAn
Minimal Impurities: With ultra-low sulfur and nitrogen, our SiC 90% is the safest choice for producing deep-drawing (DDQ) and high-strength low-alloy (HSLA) steels.
Screening Accuracy: We employ multi-stage mechanical sieving to ensure the 1-3mm range is free of oversized lumps that cause charging blockages.
SGS Verified Quality: Every shipment is accompanied by a full lab report. We welcome independent third-party inspections at the port of loading to verify chemical and physical specs.
FAQ: Frequently Asked Questions
Why is 90% purity SiC preferred over 88% for high-alloy steel?
High-alloy steels have very tight tolerances for impurities. SiC 90% provides a higher concentration of active elements with significantly lower levels of Fe₂O₃ and Al₂O₃, which ensures a cleaner final product and more stable chemistry hits.
How does the 1-3mm size improve recovery in the ladle?
The 1-3mm granules have the optimal mass to penetrate the slag-metal interface. Finer powders often get trapped in the slag or lost to the exhaust, while 1-3mm grains sink into the metal for maximum absorption.
Can SiC 90% replace 100% of my current recarburizer?
In many heats, yes. Because SiC 90% contains approximately 27% Carbon with very high recovery, it can replace a large portion of petroleum coke or anthracite, while providing "free" Silicon at the same time.
Does using Silicon Carbide affect the nitrogen levels in the steel?
Actually, it helps lower them. Many coal-based recarburizers are high in nitrogen. SiC 90% is virtually nitrogen-free, making it the ideal additive for nitrogen-sensitive steel grades.
What is the typical addition rate per ton of steel?
For standard deoxidation, 1.5kg to 3.5kg per ton is typical. However, for slag conditioning or significant Silicon/Carbon pickup, the dosage can be adjusted based on the specific furnace model and scrap quality.
How does ZhenAn protect the material during sea transit?
All export-grade SiC is packed in heavy-duty, double-layered jumbo bags with internal PE moisture-proof liners. This prevents moisture pickup and ensures the material stays dry even during long-distance maritime shipping.
