Steel shank/core is a precision cylindrical component in stopper rod systems that controls molten metal flow in continuous casting.
The steel shank/core is a critical structural component within stopper rod systems used in continuous casting operations. It serves as the central load-bearing element that transmits mechanical force from the actuator to the refractory nozzle tip, enabling precise regulation of molten steel flow from the tundish to the mold. This component must withstand extreme thermal cycling, mechanical stress, and corrosive environments while maintaining dimensional stability and alignment.

The steel shank/core serves as the structural backbone that transmits mechanical force from the actuator to the refractory tip, enabling precise control of molten metal flow during continuous casting operations.
High-temperature alloy steels with chromium-nickel content provide necessary creep resistance, oxidation resistance, and thermal stability required for continuous operation in molten metal environments up to 1200°C.
Precise diameter, straightness, and surface finish ensure proper alignment within the stopper rod assembly, prevent binding during operation, and maintain consistent flow control with minimal wear on surrounding components.
