Slide gates use sliding plates to regulate flow through aligned openings, while stopper rods use a vertical rod that moves up/down to control flow through a nozzle. Slide gates offer better flow control precision, while stopper rods are simpler and more economical for certain applications.
Refractory ceramics provide exceptional thermal resistance to withstand molten steel temperatures (1500-1600°C), chemical inertness to prevent contamination, erosion resistance for extended service life, and thermal shock resistance during casting cycles.
Precise flow control ensures consistent steel delivery to the mold, preventing turbulence that causes defects, maintaining proper meniscus level for surface quality, optimizing casting speed, and reducing refractory wear for longer campaign life and lower operating costs.
