High-Efficiency Industrial Silicon Carbide 88% (1-3mm) for Steel Plant Deoxidation
Optimize your steel production process with ZhenAn's premium Silicon Carbide 88% granules, specifically engineered for superior deoxidation performance in modern steel plants.
- Reduce Silicon Costs: A high-performance alternative to Ferrosilicon 75 that lowers overall alloying expenditure by 15-25%.
- Optimal Thermal Balance: The exothermic reaction of 88% SiC provides "chemical heat," reducing electrical power consumption per heat.
- Precision 1-3mm Grains: Engineered for ladle furnace (LF) and induction charging to ensure deep melt penetration and zero float-loss.
- Aggressive Slag Reduction: Rapidly lowers FeO and MnO levels, leading to cleaner steel and improved alloy recovery rates.
- Reliable Bulk Supply: ZhenAn provides large-scale inventory with verified SGS/ISO certification for uninterrupted steel plant operations.
The Metallurgical Dynamics of 1-3mm SiC Granules
In the demanding environment of a steel plant, the speed of deoxidation is paramount. ZhenAn's 1-3mm Silicon Carbide Granules are specifically processed to bridge the gap between fine powders and heavy lumps. This sizing is ideal for automated feeding systems, ensuring a consistent flow rate and predictable chemical pickup.
When introduced into the molten bath, the SiC dissociation follows a strategic path:
The resulting CO gas provides a gentle stirring effect, which assists in the flotation of microscopic inclusions to the slag layer, effectively "washing" the steel.
Functional Excellence in Steel Production
Ladle Metallurgy (LF) Trimming
The 1-3mm grain size is the industry standard for ladle trimming. It dissolves rapidly enough to allow for final chemistry adjustments just minutes before casting, ensuring that the steel meets precise Carbon and Silicon specifications.
Induction Furnace Conditioning
For steel foundries using induction melting, SiC 88% provides a stable source of Silicon that does not cause the "carbon fade" often associated with metallic silicon additions. It stabilizes the melt chemistry and improves the internal soundness of the ingot.
Refractory Life Extension
By deoxidizing the slag at the slag-metal interface, our 1-3mm granules prevent the chemical "burning" of the ladle's refractory lining. This extension of ladle life significantly reduces maintenance downtime and refractory costs.

Why Procurement Teams Choose ZhenAn SiC 88%
- High Flowability: Our 1-3mm granules are triple-screened to remove oversized lumps and excessive fines, making them perfect for pneumatic or gravity-fed silo systems.
- Low Nitrogen Input: Critical for producing high-strength, low-alloy (HSLA) steels where nitrogen pick-up must be strictly limited.
- Global Export Expertise: ZhenAn manages the entire logistics chain, providing DDP/CIF terms to major steel hubs in the US, Europe, and Southeast Asia.
FAQ: Frequently Asked Questions
1. Is 1-3mm sizing better than 0-1mm powder for ladle deoxidation?
While powder reacts faster, 1-3mm granules are generally preferred for open ladles. The granules have enough mass to penetrate the slag layer and reach the molten metal, whereas powders can sometimes be trapped in the slag or lost to the exhaust system.
2. How does SiC 88% impact the sulfur content of the steel?
ZhenAn SiC 88% is inherently low in sulfur (typically <0.05%). By replacing traditional high-sulfur carbon raisers with SiC, steelmakers can achieve lower final sulfur levels without additional desulfurization steps.
3. What is the "Silicon Equivalent" of SiC 88%?
For calculation purposes, 100kg of SiC 88% typically provides about 61kg of Silicon and 26kg of Carbon. This high concentration allows for significant reduction in the volume of ferroalloys required per heat.
4. Can this material be used in automated feeding systems?
Yes. The 1-3mm sizing is specifically designed for high flowability. It does not "bridge" or "clog" in hoppers, ensuring that the precise weight of deoxidizer is delivered to the melt every time.
5. How does ZhenAn ensure the 88% purity is consistent?
We operate our own laboratory and perform batch-wise testing using X-ray fluorescence (XRF) and wet chemical analysis. Every shipment is accompanied by a Certificate of Analysis (COA) that matches the specific batch in the container.
6. Does the material require any special handling for safety?
Silicon Carbide is a stable, non-hazardous mineral. However, like all industrial granules, it should be handled with standard PPE (gloves and dust masks) to prevent inhalation of dust during the discharging process.
