Based on the burned sliding gate plate, we have developed the unburned complex sliding gate plate with excellent performance.
Features: unburned complex sliding gate plate has good effect and low cost on small and medium-sized ladle
High temperature burned alumina carbon sliding gate plate features: high strength, anti-scour, good thermal shock performance
Application:steel ladle and tundish continuous casting
