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.

Low Porosity (≤10%): Prevents zinc infiltration, preserving crucible integrity and material purity.

4. Customized for Zinc Workflows

Tapered Shapes for precise pouring in galvanizing baths.

Integrated Skimming Ledges to streamline slag removal.

Sizes: 5L to 300L, tailored for small-scale workshops to industrial zinc processors.
