Graphite rods for stirring metal in a crucible are used to homogenize the structure of the molten alloy immediately before pouring it into the mold.
It is not recommended to use metal rods or similar materials for stirring molten metal immediately before pouring it into the mold, as the alloy may become contaminated with metal oxides.
Graphite rods are 250 mm long and available in diameters of 10, 15, 20, and 25 mm.
