High-Performance Silicon Carbide 88% (1-3mm) - Premium Granular Deoxidizer for the Foundry Industry

ZhenAn's Silicon Carbide 88% in 1-3mm granular form is engineered specifically for foundry applications, delivering superior deoxidation performance and enhanced metal quality.

Eliminate Gas Defect Scrap: Drastically reduce hydrogen and nitrogen-related pinholes for pressure-tight, defect-free castings
Precision 1-3mm Sizing: Optimized granular distribution ensures rapid dissolution and 95%+ Silicon recovery in induction furnaces
Superior Graphite Nucleation: Increase eutectic cell count to prevent brittle "white-mouth" (chill) in thin-walled iron components
Slag Volume Reduction: Highly reactive formula reduces iron oxide in the slag, minimizing metal loss and skimming labor
ZhenAn Direct Logistics: Factory-scale production ensures stable chemical purity and JIT (Just-In-Time) delivery to your foundry

The Metallurgical Advantage of 1-3mm Granular SiC 88%

In the competitive landscape of iron casting, achieving consistent mechanical properties is a constant challenge. ZhenAn's 1-3mm Silicon Carbide serves as a vital metallurgical conditioner. Unlike traditional ferrosilicon, SiC provides a unique carbon-silicon synergy that modifies the solidification kinetics of molten iron.

The chemical reaction within the induction furnace or ladle is highly efficient: SiC + FeO → Fe + Si + CO↑. This reaction is strongly exothermic, meaning it generates internal "chemical heat," which helps maintain the fluidity of the melt without increasing external power consumption.

Practical Benefits for Foundry Applications

Microstructure Refinement

The 1-3mm granules act as powerful pre-inoculants. By providing a high density of stable nuclei, the SiC ensures that carbon precipitates as fine, evenly distributed graphite flakes (Type A) rather than brittle carbides, significantly improving the machinability of the iron.

Cost-Effective Alloying

Silicon Carbide 88% is the most economical way to increase both Carbon and Silicon levels simultaneously. By utilizing the "double-acting" nature of SiC, foundries can reduce their reliance on expensive high-purity pig iron and specialty carbon raisers.

Slag Reduction & Lining Protection

Aggressive slag is the primary cause of refractory failure. Our SiC 88% aggressively "cleans" the slag by reducing its FeO content. This results in a dry, non-aggressive slag that is easily removed and does not chemically attack the furnace lining.

Technical Specification & Batch Analysis

The following parameters define the metallurgical consistency of ZhenAn 1-3mm Silicon Carbide granules, specifically processed for high-performance foundry lines.

Property Parameter	Guaranteed Value	Physical Standard	Performance Data
SiC Content (Min)	88.0%	Size Distribution	1.0-3.0 mm (92% min)
Aluminum (Al)	≤ 1.1%	Melting Point	2,730°C (Dissociation)
Free Carbon (C)	≤ 3.5%	Moisture Content	≤ 0.4%
Ferrous Oxide (Fe₂O₃)	≤ 1.4%	Bulk Density	1.52 g/cm³
Phosphorus (P)	≤ 0.04%	Angle of Repose	32° - 35°

Why Leading Foundries Partner with ZhenAn

Reduced Scrap Rates: Consistent deoxidation leads to a significant decrease in casting rejection due to slag inclusions or gas holes
Controlled Sizing: Our 1-3mm granules are triple-screened to ensure they are dust-free, ensuring that the material reaches the molten bath rather than being lost to the exhaust system
SGS & ISO Compliance: Every shipment is accompanied by a full laboratory report, ensuring that the chemical signature of your melt remains within tight tolerances

FAQ: Frequently Asked Questions

1. Is 1-3mm the best size for induction furnace melting?

Yes. The 1-3mm size is small enough to have a massive reactive surface area for fast deoxidation, yet heavy enough to sink through the slag without being lost to the extraction system, providing more uniform recovery than large lumps.

2. How does SiC 88% improve the "chill" factor in iron?

By increasing the silicon activity and providing carbon nuclei, SiC 88% pushes the iron away from the "white iron" (carbide) zone and into the "gray iron" (graphite) zone, even in thin cross-sections that cool rapidly.

3. Can I use SiC 88% in ductile iron production?

Absolutely. While used most commonly in gray iron, it is an excellent deoxidizer for ductile iron base metal. It ensures the metal is "dead" (fully deoxidized) before the magnesium treatment, increasing the efficiency of the nodularizer.

4. What is the typical shelf life of these granules?

If stored in a dry, covered environment in the original ZhenAn jumbo bags, the material has an indefinite shelf life. It does not oxidize or degrade at room temperature.

5. How much Silicon is recovered from SiC 88%?

Under standard induction furnace conditions, you can expect a 92% to 95% recovery rate for Silicon and an 85% to 90% recovery rate for Carbon, making it much more efficient than coal-based recarburizers.

6. Does ZhenAn provide customized size specifications?

Yes. While 1-3mm is our standard metallurgical grade, we can adjust the screening (e.g., 1-5mm or 0-3mm) and chemical balance to meet the specific requirements of your automated dosing system.
