Ladle nozzle

Ladle nozzles, also known as ladle slide gate nozzles or ladle slide gates, are refractory components used in the steelmaking industry to control the flow of molten metal from the ladle to the tundish during continuous casting processes.

Product Details

Ladle Upper Nozzle The high-quality upper and lower nozzle are made of sintered corundum, fused corundum, fused mullite, etc. as the main raw materials. They are bonded with new resin combination, formed by high pressure, fired by high temperature hydrogenation, and free from oil immersion. with high strength, good high temperature resistance and corrosion resistance, strong thermal stability, long service life, etc.
