Where are zirconium oxide plates mainly used in steelmaking?

 

In steelmaking production, zirconium oxide sliding plates are indispensable high-performance refractory accessories. Due to their advantages of high-temperature resistance, corrosion resistance, and low wear, they are widely used in key stages of steelmaking and continuous casting. They are particularly suitable for harsh high-temperature molten steel conditions and are one of the core components ensuring the safety and stable production of steelmaking. Many steel enterprises will prioritize the selection of zirconium oxide sliding plates when choosing refractory accessories. The core reason is their durability and stability. Today, we will elaborate on its main application scenarios in steelmaking.

This is the most common and essential application scenario of zirconia sliding plates. Whether it is for the production of ordinary carbon steel or special steel, it is almost indispensable. Steel ladles and intermediate tundishes are the key equipment used to store and transfer molten steel during steelmaking. The sliding water outlet is the "switch" that controls the flow rate of molten steel and regulates the pouring volume. And the zirconia sliding plate is the core component of this "switch".

In the production of special steel (such as stainless steel, alloy steel) and calcium-treated steel, zirconium oxide sliding plates are indispensable. Zirconium oxide sliding plates can resist the erosion of strong corrosive steel slag and molten steel, are not prone to peeling or damage, can effectively reduce inclusions in the billet, improve the surface quality and intrinsic performance of the billet, and avoid production interruptions caused by sliding plate damage. They are particularly suitable for the production of special steel with high requirements for pouring stability.

Apart from the sliding water nozzle slide plate, the zirconium slide plate can also be used in some high-temperature areas of the steelmaking furnace and continuous casting equipment as a protective and isolation component. For example, at certain positions of the continuous casting mold, and as an auxiliary protective measure for the high-temperature inner lining of the steelmaking furnace, by leveraging its high-temperature resistance and corrosion resistance properties, it protects the equipment itself, reduces the damage caused by high temperatures and steel slag to the equipment, extends the equipment's service life, and lowers the equipment maintenance costs.

For steel enterprises, the use of zirconia sliding plates not only ensures the safety and stability of steelmaking production, reduces production accidents, but also improves the quality of steel billets and lowers maintenance and replacement costs. It is an indispensable and important refractory accessory in modern steelmaking production.
