FLOW CONTROL
Precision refractories that control molten steel, directly impacting steel quality
Flow control refractories regulate the flow of molten steel during continuous casting. They must survive extreme thermal shock, erosion from high-velocity steel, and chemical attack from steel and slag, all while maintaining dimensional tolerances critical to casting quality.
