Products Description

Upper nozzle(Stationary nozzle)is located within the tundish lining and conveys steel to the

controlling exchangeable tundish nozzle, which determines the steel flow. The stationary nozzle must be capable of withstanding long sequence times.Our Upper nozzle that incorporates a ultra-high densityLKZN-M or LKZN-H insert. The insert provides excellent erosion resistance and can provide extended casting sequence times.The lower surface of the stationary nozzle is ground to exacting tolerances to ensure maximum surface contact between the two nozzle components.

Lower Nozzle (EXCHANGABLE) is located within an assembly that is fixed to the bottom of the tundish.The design of the exchangeable nozzle can vary according to the system manufacturer.

We supplying a range of zirconia inserts and composite nozzle designs for the exchangeable

metering of steel. Zirconia inserts can be supplied for on-site assembly into metallic holding blocks where cementing, grinding, size banding and on site drying are required prior to use.

Product Production Process

Exchangeable tundish nozzle was manufactured by both cast process of fine grained alumina method or press process.

How to replace the refractory exchangeable tundish nozzle

1. Before replacing the exchangeable tundish nozzle, the medium pipe flowing through the equipment must be closed and the original tundish nozzle must be removed.

2. When installing a new refractory material exchangeable tundish nozzle, the installation position of the equipment should be cleaned and ensure that the new tundish nozzle completely matches the installation position of the machine body.

3. When installing a new tundish nozzle, wear-resistant bricks with high-quality sealing properties must be used, and the bolts and nuts must be tightened evenly during the installation process.

4. After the installation is completed, the collapse pressure of the equipment should be retested and ensure that it can work normally after startup.
