Jumbo zirconia nozzle insert for tundish upper nozzle-working life can reach 60hours continuously

Products Features:

Embedded our 5.4g/cm3 density of the zirconia insert for the tundish lower nozzle as flow controlling of steel liquid and slag refractory material widely used in the tundish in steel plant. It is most suitable to the upper nozzle (Inner nozzle)above the lower nozzle (outer nozzle) of the tundish furnace, after embedded in the alumina or corundum quality body, the composite tundish nozzle can be used in the sliding system of ladle and tundish directly, do not desired to heat before using. Especially used for smelting the special high grade steel types, such as low carton steel, alloy steel etc.

Production Process

Our low density of the zirconia nozzle insert as flow control refractory is made of the high quality of e-fuzed magnesia and zirconia grain and sand, bonding agent, through the the automatic system mixing, drying, pressing, inspecting, sintering, etc. series system process, then pack into the carton, and wooden box with the desired shipping mark sticked, then deliver to the china mainland and oversea from our factory.
