Flow control refractories are critical components in continuous casting and molten metal handling systems, where controlled flow, dimensional accuracy, and resistance to thermal and mechanical stress are essential. Champion Ceramics offers a range of precision-engineered slide gate, nozzle, well block, and gas purging refractories designed to perform reliably under severe steelmaking conditions.
Products are formulated with controlled chemistry, low porosity, and high-density microstructures to ensure stable performance under high temperature, pressure, and metal flow conditions.
Specialized compositions are available to suit different casting practices, steel grades, and operational requirements.
