What matching slide gate plate works with metering nozzle?

For standard carbon steel production, alumina-carbon slide gate plates are the economical match for composite metering nozzles. For alloy steel and long-sequence casting, alumina-zirconia-carbon or zi

Why does tundish metering nozzle crack during continuous casting?

Tundish metering nozzle (tundish nozzle / metering nozzle) is a key flow control refractory installed at the bottom of the tundish, which stabilizes molten steel flow and controls casting speed. Crack

Will the zirconia nozzle shatter as soon as the pour begins?

More than 95% of early fracture incidents are related to improper handling or substandard products, rather than issues with the zirconia material itself.

Why are zirconia-based slide plates used in steelmaking?

Unless you're an expert in the steel industry, you've probably never heard of “zirconia slide plates.” But there's one thing you need to know: without them, molten steel would be impossible to control

What Is the Difference Between a Tundish Nozzle and a Metering Nozzle？

The key difference between a tundish nozzle and a metering nozzle lies in their distinct functions: the tundish nozzle serves as a “stable conduit” to ensure the smooth flow of molten metal, while the

What Are the Advantages of CNC Machined Tundish Metering Nozzles?

In the continuous casting process, the dimensional tolerances and surface finish of the sizing nozzle’s inner bore directly affect the stability of the liquid level in the mold and the pulling speed.

Why Choose Zirconia Tundish Nozzles for Molten Steel Casting?

Zirconia Tundish Nozzles are primarily chosen for their excellent high-temperature resistance, corrosion resistance, and chemical stability. They offer a longer service life, reducing the frequency of

Guide to Common Problems and Troubleshooting for Sliding Gate Systems

Drawing on years of hands-on industry experience, this guide identifies the most common issues with sliding gate systems, their causes, quick troubleshooting methods, and professional solutions to hel

How can nozzle blockages be prevented during continuous casting?

Preventing blockages in continuous casting nozzles is a systematic endeavor. By controlling molten steel quality at the smelting stage, upgrading nozzle hardware, refining process operations, and supp
