Graphite Stopper Head

Graphite Stopper Head

Graphite stopper heads are essential components in steelmaking ladles and tundishes, designed to control the flow of molten metal during casting operations. These graphite-based stoppers offer excellent thermal conductivity, erosion resistance, and machinability, ensuring precise regulation of metal flow rates and minimizing downtime during casting processes.
