Silicon Carbide Graphite Crucible for Zinc Melting
Precision-Engineered for Efficient, Low-Temperature Zinc Processing
Product Overview
Our Silicon Carbide Graphite (SiC-Graphite) Crucibles are meticulously designed for zinc melting and alloying applications, combining the durability of silicon carbide with the thermal efficiency of graphite. Optimized for low-temperature stability (operating range: 400°C–800°C), these crucibles excel in galvanizing, zinc alloy production, and battery manufacturing, where precision and material purity are critical.
Key Differentiators
1. Zinc-Specific Thermal Management
Low-Temperature Efficiency: Engineered for rapid heating at 400°C–800°C, reducing energy consumption by 20% compared to standard crucibles.
Thermal Shock Resistance: Withstands frequent start-stop cycles common in batch zinc processing without cracking.
2. Enhanced Corrosion & Oxidation Resistance
Zinc Adhesion Prevention: Proprietary inner coating minimizes zinc buildup and oxide formation, ensuring consistent melt quality.
Slag Resistance: Reinforced material composition resorts zinc slag penetration, extending service life by 30%.
3. Precision for High-Purity Applications
Ultra-Smooth Surface: Reduces zinc drag-out and contamination, crucial for electroplating and high-purity zinc alloys.
