Graphite SiC Crucible for Induction Furnace | High Temperature Metal Melting Crucible

Description

Graphite SiC Crucible for induction furnace is a high-performance refractory container specially designed for melting and holding non-ferrous metals under high temperature conditions. It combines the excellent thermal conductivity of natural graphite with the outstanding corrosion resistance and thermal shock resistance of silicon carbide, making it an ideal choice for aluminum, copper, brass, zinc, and other metal melting applications.

Zibo Shengkai New Materials Co., Ltd. manufactures high-quality graphite SiC crucibles using advanced production technology and carefully selected raw materials to provide stable performance, long service life, and reliable operation in industrial melting environments.

Application of Graphite siC Crucible in Induction Furnace

Induction furnaces require crucibles with excellent thermal transfer efficiency, mechanical strength, and resistance to repeated heating cycles. Graphite SiC crucibles are widely used in:

-Aluminum melting and casting

-Copper and copper alloy melting

-Brass and bronze melting

-Zinc and lead alloy processing

-Precious metal melting

-Non-ferrous metal recycling

The crucible can withstand frequent heating and cooling cycles while maintaining structural stability, helping foundries improve melting efficiency and reduce production downtime.

Features of Our Graphite SiC Crucible for Induction Furnace

1. Excellent Thermal Conductivity

The high-quality graphite material inside the crucible provides fast and uniform heat transfer. During induction furnace operation, the crucible can efficiently transfer heat to the metal charge, reducing melting time and improving energy utilization.

2. Outstanding Thermal Shock Resistance

Induction furnaces involve rapid temperature changes during charging, melting, and pouring processes. The optimized graphite and SiC composition provides excellent thermal shock resistance, reducing the risk of cracking caused by repeated temperature fluctuations.

3. Strong Oxidation and Corrosion Resistance

Our graphite SiC crucibles are treated with high-temperature anti-oxidation coating technology. The protective coating reduces graphite oxidation and improves resistance against molten metal corrosion, extending crucible service life.

4. Low Molten Metal Penetration

The dense structure of the crucible helps prevent molten metal penetration and slag infiltration. This maintains crucible strength during long-term operation and improves melting stability.

5. Customized Sizes and Shapes Available

Different induction furnaces require different crucible dimensions. We provide customized graphite SiC crucibles according to:

-Furnace capacity

-Melting material

-Working temperature

-Installation requirements

Available shapes include cylindrical, conical, bowl type, and special customized designs.

Manufacturing Technology

Our graphite silicon carbide crucibles are produced with advanced cold isostatic pressing (CIP) technology, which creates a uniform and compact structure.

The main raw materials include:

-High purity natural flake graphite

-High quality silicon carbide aggregate

-Special refractory additives

The one-piece forming structure improves mechanical strength and reduces defects caused by traditional manufacturing methods.

Each crucible undergoes strict quality inspection before delivery to ensure stable performance in industrial applications.
