Customizable Size Refractory Materials Tundish Nozzle Thermal Shock Resistance
Tundish Nozzle Lower Nozzle For Refractory
Description
The upper and lower nozzle are composed of three parts, the outer coat is aluminum-carbon, the inner core is zirconium, and the base brick is aluminum-magnesium carbon.By the precision process formula compression molding, high temperature firing assembly.
Tundish Lower Nozzle for ladles are made from corundum, bauxite, flake graphite, anti-oxidants and phenolic resins. They show features of excellent thermal shock resistance, stable performance, good corrosion and erosion resistance, and strong cracking resistance.
