Product Description
Zirconia Nozzle Inserts for Tundish Metering Nozzle
We manufacture a very wide range of high quality Zirconia Nozzle Insertss. Zirconia Nozzle Insertss are basically used for controlling the flow of steel from the Tundish to the Continuous Casting equipment. Different kind of Zirconia Nozzle Insertss include, Alumina, Alumina Carbon, Zirconia Alumina Nozzles, which are manufactured for single to multiple casting application. Alumina Carbon Zirconia Nozzle Insertss are made with Isostatic Pressing Process. which gives better performance compared to other nozzles. Zirconia Nozzles are manufactured using 65% to 95% Zirconia. it can be used where application demands Timing time upto 40hrs for Single to Multiple Casting.
Zirconia Nozzle Inserts is an important component of continuous casting. Through the Zirconia Nozzle Inserts, 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 Inserts remains constant is a most important measure of the quality. Usually, it is measured through the total use time in actual production.
Our Zirconia Nozzle Inserts has the properties of high refractoriness, good resistance to erosion, and can bear rushing scour etc.
Our customer included NEW SHALIMAR, SHALIMAR, MURTZA, PUNJAB. ANGANG,BAOGANG.
structural principle
Zirconia Nozzle Inserts for Tundish Metering Nozzle
The Zirconia Nozzle Inserts 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 Inserts is located at the bottom of the tundish, it's the channel of liquid steel to flow from the tundish into the crystallizer.
