Graphite Double Ring Crucible

Graphite Double Ring Crucible is a precision-machined graphite crucible featuring an integrated double-ring positioning structure for induction melting, precious metal processing, and high-temperature applications. 

Precision-machined double-ring positioning structure improves crucible stability in induction furnaces and supports automated melting operations.
Thermally stable graphite materials provide high-temperature performance and thermal shock resistance during repeated heating and cooling cycles.
High-purity graphite materials help minimize contamination risks and maintain melt quality during precious metal processing.
Optional densification treatment reduces graphite porosity and helps reduce molten metal penetration during extended melting operations.
High thermal conductivity enables rapid heat transfer and stable temperature distribution for efficient melting processes.
