Zirconia nozzle refractory insert for tundish nozzle_Refractory mineral abrasives materials castables ramming materials-HENAN HONGTAI KILN REFRACTORY CO.,LTD.

Description

zirconia nozzle tundish is an important component of continuous casting. Through the zirconia nozzle tundish, the molten steel flows from the tundish into the crystallizer. During this process, the outlet aperture will be eroded and widened, the amount of molten steel per unit of time increases and the surface of molten steel in the crystallizer rises, which requires increasing casting speed to digest the excess molten steel. With the further erode and widen of outlet aperture, adjusting casting speed can not digest all the excess molten steel, then releasing the excess molten steel through the mouth of the emergency is adopted though it's a waste of steel enterprises. Therefore, whether the outlet aperture of zirconia nozzle tundish remains constant is a most important measure of the quality. Usually, it is measured through the total use time in actual production.

The structural principle:

The zirconia nozzle tundish is a combination of inner core and exterior. The inner core is made of stabilized zirconia and zircon sand, producing through molding machines and high-temperature calcination. The exterior is made of zirconium and corundum, producing through molding machines and low-temperature baking. zirconia nozzle tundish is located at the bottom of the tundish, it's the channel of liquid steel to flow from the tundish into the crystallizer.

Function of the zirconia nozzle tundish

1. Convey molten steel;

2. Control the flow rate of molten steel.
